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.

great value great speaker!!!!!!

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

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

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!!

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!!

Undecided

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
