New and Improved Alpine Type-R:

Introducing the 10" Dual 4 ohm Type-R subwoofer powering a peak of 1800 watts of pure power! This reinforced pulp cone woofer delivers the best bass output, while having enhanced audio playback to become your ideal sound system. Type-R's new depth design offers a 20% reduction while adding the new and improved magnet structure. With this updated double-stacked strontium magnet, this product gains over 20% more motor force to provide a louder, cleaner bass. The optimized CRC machined motor creates an even magnetic field to provide the user with less distortion and overall improves the subwoofers power handling. This subwoofer features a High-Amplitude Multi Roll (HAMR) to provide excellent excursion with overall better output. Having a new and improved airflow management system controlling the temperature of the voice coils, the air is redirected across the heatsink to avoid overheating. With heavy playing time, this heatsink feature minimizes the amount of compression to reduce any heat damage to the voice coils giving you a long-lasting subwoofer.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Type-R (Alpine)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
10"
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
1800 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
600 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Dual
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
26 - 400 Hz
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
83 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
20 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Dark Gray
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Kevlar Fiber
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Santoprene Rubber
Magnet Structure
Defines the overall structure of the subwoofers magnet.
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
Optional (Accessory required and sold separately)
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.5 cubic feet
Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.0 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.8 cubic feet
Optimum Ported Box Volume
This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.5 cubic feet
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
6"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
9-1/16"
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

No

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 10.
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 10.
Efficiency Bandwidth Product (EBP)
This number represents the trade off between having an efficient woofer and one with a wide bandwidth. To calculate this number, take the Fs and divide it by the Qes. If the number is below 50, the woofer is designed for a sealed enclosure only. If it's between 50-100 it can be used in either. Lastly, if it's greater than 100 it's designed for vented enclosures.

Alpine SWR-1043D

January 22, 2012

I would recommend this sub to anybody. I had it in a crew cab Chevy Colorado in a sealed box. The sub hit all the notes well and deep. There's more than enough power there for me And I listen to mainly rock and some rap. The design of the subwoofer is great as well, very well built and the mounting depth was perfect for what i was looking for. I love it and will buy another if this one ever gives out!!!

was great unitl...

January 19, 2012

It blew on me. I had two hooked up to a RF T-1000D, Birth sheet said 1102 @ 1 ohm. So slightly under powered. For three months it sounded great! Loud, clean, clear bass but one of them blew on me last night and the other one isn't in good shape. They were in a small sealed box because I have a mustang and dont want to spend 800$ for a custom install, so it's more so my fault than sub failure. A bit of advice make sure they're in a ported box so the voice coils dont burn up on you like mine did.

Deciding which sub started and ended with 2 ohm or 4 ohm

April 21, 2013

I knew it was going to be an Alpine Type R 10" sub. All I had to do was figure out the configuration I was going to be most comfortable with now and in the future and the dvc 4 ohm was the answer. I could have looked at other subs but Type Xs are expensive so I devoted more time figuring out the best ohm load.

My certainty on Alpine subs was matched by my knowledge of the vendor I eventually purchased from and that was Sonic Electronix fulfilling through A*****.

Claims of top customer service can be posted anywhere, said by anyone. Where the rubber hits the road is when you are the party seeking customer service and receiving customer service that you were never expecting. Sonic answered the bell when I needed to complete an RMA. Weighing the cost benefit of the possibility of running into a completely unexpected scenario always has you leaning towards Sonic. I like purchasing from them and I will do so again

Ridiculous bass for only a single 10"

December 16, 2012

I got this older model Type-R and figured i'd give it a shot. I wanted to do it right and figured i could outhit my friends two twelves, so i put this ten into a ProBox 110SPB and it definitely did the job. I'm only running 400 watts rms from an Alpine MRP-M450 and it still hits harder than two twelves. The low notes player so clear and the bass is just amazing without having to empty out my wallet.

May 13, 2012

I just purchased and installed this sub in a 0.75 cu/ft sealed enclosure with a 500watt Alpine amp and it did squat. I then purchased the 101KPRO ported enclosure from Sonic. The bass now renders my rear view mirror useless due to the bass. This single sub/box combo sounds like a pair of twelves. Amazing!

Sweet subs

April 25, 2012

I have 2 of these lil guys wired down to 1 ohm and they pound. I run them for long periods of time before on 3/4 volume and they dont get hot at all they barely get warm. I have come very close to breaking my back window in my truck, if I have them too loud. If you want a small sub that can hit hard and last forever this is one of the best.

Very nice...

January 10, 2012

Once I pulled this out of the box I was very impressed with the build quality, not surprised, but impressed none the less. Sub definitely needs to broken in, cone is very stiff when new. Sound is incredible, very clean, tight bass. Wouldn't recommend for those looking for wide, boomy bass. Although with the right equipment and box probably could fulfill those needs as well. Make sure not to under power, fairly power hungry. However, when powered right, very nice.

Awesome Sub!

November 7, 2011

Placed one SWR-1043D in a 1 sq/ft sealed box at the very back passenger side corner of my 240sx hatch. I am feeding it about 500W/rms with a Kenwood KAC-8105D. It really beats!! However we placed the same setup in a downward firing under seat box for my friends GMC, wish we would have gone with two.

For the money I have few complaints. I am used to larger subs(12-15) and this is not like those. The audible bass is loud and clean but its not shaking the car next to me. Which is what I was looking for when I bought only one of these. I installed it in a .6^2ft box and am happy to have most of my trunk back to being useable.

Very Good Sub for the price

September 16, 2011

I have one of these in a chevrolet astro van, and since its only a ten i was doubting it, but was i wrong. This thing pounds, of course i made a box probably around 3 cubic feet, but this thing is nice, especially for the price. Alpine always has good things anyways so i decided to try it out, i used to have a type e but its not comparison for the lows. My box is ported and i have one in the astro and it will make the roof rack jump and make all the doors rattle. Not sure about the sealed box, tried but didnt like the sound. A VERY GOOD BUY. always check the ohms before you hook it up though.

Awesome sound

August 28, 2011

I had a bottom of the line Polk sub before I got the Alpine (the Polk blew out pretty quickly) and there's really no comparison. The Alpine is much more punchy, hits higher notes more clearly, and sounds much better. I compare it to listing to music at high volume with some decent computer speakers (Polk) to being at the concert and really feeling the bass (Alpine). You feel much more of the music, which is one of the cool things about listening to a live band. Anyways, I've had this sub for several months now (I got an e-mail from sonic-electronix asking for a review) and am a true Alpine fan.

I have one of these 10" type-r's sitting in one of my cars getting about 400 watts rms from an alpine amp. For the money, this is a great amp. It can easily push 600 watts rms cleanly. I like that the 10" hits hard and precisely. Good clean sub bass. Would def recommend to all my friends.
