New and Improved Alpine Type-R:

This 10" Type-R subwoofer offers 600W RMS enhancing your system with the cleanest sound and most efficient force control. This subwoofer has voice coils made from 180°C high temperature wire on spiral cut aluminum former enhancing structure durability. Delivering the best bass output, the Alpine SWR-1023D has been redesigned to enhance audio playback and 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. With an updated assembly, this subwoofer is able to withstand higher temperatures more efficiently without distortion allowing the best sound possible. Type-R's greatly improved installation options by allowing a shallower mounting depth. 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.
1200 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.
2 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 - 500 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-1023D AND SWR-1223D

June 17, 2011

I purchased 1 Alpine SWR-1023D and 2 SWR-1223D sub woofers.
The SWR-1023d is the latest 10 inch, 2 ohm, dual voice coil modle of the alpine type "r" sub. The srw-1223 is the 12 inch modle with the same voice coil setup.
I have been installing high preformance car audio and home theater systems for 30 years. I have built many award winning systems and i can say at this price you cant touch these subs. The only thing that comes close to this level of preformance is the jl audio w7 series subs. Which will out preform these subs by a very small margin, for $450 each. Dollar for dollar these speakers kick but, I drive the 10" with a class d 1024 watt mono amp and drive the 2-12" with a 1800 watt per ch stereo amp. These amps run the speakers very hard but can not seem to hurt them. Other speaker systems that I have run with these amps ran out of x-max (forward or rearward cone movement) but these have handeled everything i have thrown at them. I am sure if you get stupid with these speakers you can break anything but if you use them properly they will last and kick your but with incrediably loud and low bass.

GREAT SUB!

March 19, 2011

I got this sub when it first came out for 170-180 about half a year ago. It was my first sub and i had it hooked up to an old Rockford amp that put out 550 rms in to 2 and it was ok alot of people hate on tens when the only big diff. is that 12's and 15's and others just push more air. And just a couple weeks ago i baught a Alpine Mrp-m1000 amp and hook it up to the type r i had it at 4 ohms so ithe amp was pushing 600W into the sub and thats what it Rms is anyways and let me tell you this thing was LOUD .........I HIGHLY Recommend this sub and if you do get it then deff. look in to getting an mrp-m1000 it costs alot but it is a really good amp and if you upgrade to type x ( which i am and just ordered ) you will already have an amp

BOOOOOMMMM!

October 17, 2011

if there were a 6th star it would be selected in all of the catagories this sub is amazingly easy to install and kicks like none other. Not saying that you Should but i have 2 of these into a monoblock that pushes 1500 watts RMS through the subs and these subs have never thought about blowing. Extremely well made. You will not be disapointed in the purchase of these subs cleanest bass you will find.

Excellent Subwoofer, great price

October 29, 2010

This particular subwoofer, the 10" Alpine Type R (SWR-1023), is a 500 watt RMS sub that is great for someone who is looking for some high quality sound, with a really good amount of thump, and at a low price.

The sub is installed in a custom fiberglass enclosure (0.7 CuFt) built into the right cubby behind the wheel well. It looks great and sounds even better.

For the price, you simply won't find a comparable subwoofer. You may find ones that claim more power handling capability, and you'll certainly be able find some that cost less. But this one will have better sound, better quality, and better reliability.

very well built

May 7, 2010

Way better than what i had before. I replaced Phoenix Gold with these. It's like day, and night. Good quality, good sound. they barely move, and produce nice bass. Very tight, they also fit in a small box. I had to make a ring spacer out of 3/4" particle board, but managed to get them under the rear seats of my 2004 dodge ram. I recommend these if you have limited space. reasonable price too!

What did you say?

December 15, 2011

I've got two of these under the rear seat of my Nissan Titan powered with 1200 watts from a Cadence ZRS-C65. I wish I could have two 12's in a ported enclosure, but that's not feasible with keeping the truck's seat configuration. Despite that, these obviously get loud in a 0.6 ft^3 per sub sealed enclosure. With the two bass boost options on the amp they get reasonably low, as in B- overall, and an A+ rating for diameter and enclosure type and volume.

When supplied with Lil' Wayne's "A Milli" or Mt. Eden's "Omen" I end up deaf for half a day.

alpines #1!

October 8, 2010

i bought two alpine type-r 10" and they won my class in a M.E.C.A competition.... only was running on 400 watts but i punched out 135.7DB on the sound meter...i ran them in a 4th order bandpass so they should have been louder than 135.7DBif i was ported but i ran with a walmart amp and still won. type r's are awesome! best bang for the buck!
