Customer Testimonials  

"I recently purchased a Tempest driver for installation into a home built subwoofer. Performance of the subwoofer has been terrific with the new driver. The box is 178L (internal) made from birch plywood. I'm using an old JBL PS120 100 watt amplifier. The subwoofer was originally tuned with 4" diameter schedule 40 PVC pipe. Air velocity at 20 Hz was so high that the port made loud noises from the air flow. That problem was solved by using 6" diameter PVC pipe tuned to 19 Hz. I'm also using an ART 351 equalizer to flatten room reponse. With the Tempest driver, 6" diameter port tuned to 19 Hz, and a little equalization on the ART 351 (+4 db at 20 Hz) the subwoofer plays flat to 20 Hz in my living room which is >6500 cu ft. Output level is also very good in that large room. Output and frequency response match or exceed the performance of my Paradigm PW-2200 subwoofer, which I modified with a longer 4" diameter flared tube to bring its box resonance down to 22 Hz. Without that modification, the PW-2200 would normally not perform very well at 20 Hz. Using a shorter 23 Hz port and listening to music, the Tempest fills my entire basement (>20,000 cu ft) with high levels of bass. A little boomy, but a lot of fun. I've also used this opportunity to enlist the aid of my younger 13 yr old son and teach him about subwoofer design. We've had a lot of fun together. Thanks for selling such a wonderful product at a reasonable price." --David S.

".......he was great to deal with, I highly recommend them." --Armen K.

"I was treated to some of the highest quality bass that I've ever heard"...."To say I'm extremely pleased is to say the least. It is good to know that I was able to purchase a Tempest based sub achieving bass performance that I would have to pay much more for else where." -- Darren F.

"I have to say that the experience of buying the sub was top-notch."...."I've never heard anything like it, and I've listened to a lot of subs and nothing even comes close to it for even 3 times the price! It's absolutely a keeper, Kyle would have to pry it out of my cold, dead hands to get it back now."...."Bravo guys! Incredible product!" -- Jerry W.

"I ordered a 88.5 liter sub cabinet and it is a work of art. If you want to build a sub and don't have the wood working tools these guys are the way to go." -- Gary E.

"This is my first subwoofer, but this thing rocks!"...."This was the best shopping experience I have ever had, and it was online to boot." -- Allen L.
