Reaper Build and Performance

The RW1-8's Closed Cell Polyurethane Surround is the same compound used in the making of countless gasket and insulation products, known for its adhesive bonding properties. Reaper PU surrounds have built-in expansion pockets to flex and relieve stresses during extreme use. Surrounds of Reaper woofers are double overcast stitched directly to the cone surface. In addition to superior adhesives, overcast stitching improves the conventional bond between cone and surround.


Reaper Build and Performance

Heat build-up is a leading cause of catastrophic woofer failure. Venting built into the T-Yoke, back plate, and voice coil extract and dissipate heat, ensuring Reaper woofers remain cool and going for longer play times. In addition, Reaper woofers use 1" long, 2" diameter 100% OFC Copper voice coils and vented Aluminum former to further handle, extract and dissipate any heat build-up, resulting in improved power handling.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Reaper (Power Acoustik)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
8"
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.
600 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.
240 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.
Single
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.
2"
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".
89 dB
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.
Black
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.
Polypropylene
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.
Ribbed Poly-Foam
Magnet Structure
Defines the overall structure of the subwoofers magnet.
Single Stacked
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.
No
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.
0.45 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.
0.75 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.
0.75 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.
1.0 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.
4-1/4"
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.
7-13/16"
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.
39.72 Hz
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.
62.9409 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.
0.5813
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.
0.6491
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.
4.0380 ohms
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.
5.5675

great value great speaker!!!!!!

January 8, 2015

i bought 2 of these speakers about 4 months ago and put off reviewing them untill i had time to get them nice and broke in. i have them under powered with a 600 watt boss amp running the pair and even with the lack of power they push out 126 db on my spl gauge and verry clean bass with no noticable distortion. all in all i was verry pleased that a speaker which cost less than $50 and fit into a narrow truck box would hit this hard and sound this clear. amazing value!!!

Best value and real surprise Bass accuracy and volume

June 25, 2013

I built a 42" x 10" x 10" rectangular style box and divided it right in the middle giving them 1 cubic ft each. I placed the speakers 4 inches from the ends and used sch 80 3' PVC to port the same side. I have them running bridged on 1/2 of a Pyramid Gold Series 4ch 1800w amp.

The bass is so accurate and so much more than I had anticipated. All my friends are blown away by how much sound you get from them. I put this box in the cargo space of a 1990 Geo Tracker LSI. You cant go wrong with these.

PS: they are as tough as they look.

Biggest 8's for the buck

September 20, 2013

I purchased 2 of these for my 1990 Geo Tracker restore and WOW!!!! These things just don't quit. I used 1 cft per speaker with a 3" pvc port to 1.5 inches from the back of the box and they are extremely accurate. I am running both briged off of one side of an 1800watt 4 channel amp (so essentially 900 watts peak) and they run clean for days :)

Great bass for a great price!!

January 8, 2016

So for a while, I have been contemplating on switching out my 8in sub for a 10in. I fabricated my own 8in sub box (measured at 0.35 cubic feet) a while back for my 2012 Honda Fit, but the sub that I had just wasn't doing it for me. So I decided to give an 8in sub one more chance. This sub SURPASSED my expectations. First off, the sub is very well built and looks mean. They say that you can't get much deep bass from 8in subs. This sub has AMAZING deep bass and AWESOME punch!! I highly recommend this sub to anyone that wants a sub that will not only save space, but also save money and produce fantastic bass!!

Power Acoustic RW1-8 rocks

April 17, 2016

These litte 8's hit hard. I have 2 in a share 1.5ft3 box and I only have 60 watts to each, not even close to the 250 they are rated for. They fill my suv with bass. With more more power to these they would be even better. I highly recommend them.

Good sound

March 26, 2016

I used them to rebuild some super old RadioShack speakers, they sound great; hit all the tones from sub low through the low range and the louder they go the better they sound, I was able to eliminate my subwoofer from my sound system with these in my RadioShack bookshelf speakers. overall I'm exceptionally pleased.

I got one because it was so cheap and looked touch as nails.. Put it in a 0.85 cu ft sealed which is within its design and I couldn't get it to do much.. I know it's just an 8in.. But at 240 or so watts I expected more.. Might do better in ported.. 10in prolly better...I'm returning mine, I got two twelves at 1200w so maybe I am just spoiled lol

Great amp

November 22, 2015

Looks great, operates even better. Could not have asked for more from such a reasonably priced amp. Puts out plenty of juice to run my two 240 watt RMS subs. The subs clip before the amp does. Time will tell if it will last. When it is powered on, a blue light illuminates on the front panel of the amp.

It was cheap, highly rated, and recommended by a friend of mines who professionally builds performance sound systems although it was my second choice since the audiobahn sub I wanted wasn't available.

These look like durable speakers for a good price. The reviews are good. Great choice of subs for anyone who has a space restriction, or who wants punchier, more responsive bass.

will this woofer fit in a 2001 suburban LS Power Acoustik RW1_8 are will It replace the old one in the truck?
A shopper on Jul 28, 2015
Best Answer: If you have an existing 8" it can replace it. If not it will fit almost anywhere. I have had 2 of these before and was very impressed by how responsive they were. Not for big bass, but definitely adds a nice element to your music for the price.
