8" High Excursion Woofer
This high performance woofer features extremely long throw design for outstanding low frequency response, thought impossible of drivers this size. Optimized for vented enclosures, it is great for home theater or autosound applications, as a compact subwoofer, or as a woofer in a three–way design.

  Ok, so I got this little work horse back in December for a car audio application and I was very happy with the performance of this speaker. However, after just 3 1/2 months of use it failed on me. I think next time I'm going to go with another brand for a replacement sub. Not quite durable enough for me. -Jeff

  Extraordinary bass - use two woofers in an Isobaric design box (face to face). For example, construct a simple, slotted box: 11”W x 14- 3/4D x 18-1/4" T (outside dimensions) - using ¾” MDF. Install a 3/4" slot port at the bottom, 9-1/2”W x 10-3/4”D (inside dimensions). This will tune the box at 31 hz. Space the woofers 1/2" apart so they have plenty of room to move, wire the speakers in series (8ohm) and use a MCM 200 watt plate amplifier. No need for damping material. I have built two of these cabinets and the results are amazing, the lowest and most detailed bass that I have ever heard. This design will astonish any home theater enthusiast, even if they have sub-woofers that cost much much more.

  I bought this woofer for a horn-loaded car subwoofer (An Autotuba designed by Bill Fitzmaurice, to be specific) and was amazed at the output of this box. It went over so well that my wife stole mine until I built a second one for her car. I love the look on people's faces when I explain that all I've got running is a 100 watt 8" driver that cost less than $50. It replaced a dual-10" loaded sealed box that cost $600 altogether and used 1200 watts. And the new box is louder and cleaner. Awesome driver.

  I purchased this sub to build a tapped horn enclosure for it. I am using a cheap 115W amp to power it in a tapped horn enclosure about 2 cubic feet in size. This system by itself is powerful enough to hang with most 10" and 12" subs in much larger enclosures. For the price this sub cannot be beat.

  I was impressed with this woofer in a 2 cubic foot ported enclosure tuned to 30 htz and a MCM 200 watt amplifier, the bass bubbles down extremely low. However, I decided to try two woofers face to face in a 1 cubic ported enclosure (excluding the slotted port, again tuned to 30htz). The results are incredible, tremendously low, powerful bass. I did switch to a 200 watt stereo amp set in a bridged mode. Speakers are connected in series so the speaker load is 8 ohms. This speaker has a noticeably smooth response from 25htz – to 100htz. A wonderful speaker and a great value, I may try the cast iron version next.

  I installed this 8" woofer in a Toyota RAV4. I mounted it in a .24 cu. ft. ported enclosure (along with an 8" grill MCM 50-525 and matching blue carpet). It was hard installing a 13" port in that small of a box, but it was worth it! I powered this woofer with a Power Acoustik OV2-420 car amplifier. Let me tell you, this speaker surprised me after I installed it. It handles the 190 watts RMS well and complemented the stock speaker system well. I couldn't believe you could hear the woofer outside the RAV4. The stock system had too much midbass, so to balance it out, I turned down the bass knob and turned up the subwoofer. I would argue that this sub has better sound quality and more deep bass than some more expensive subs that I have heard that require much larger boxes. Why would you take up your whole cargo area when you can build a box the size of a sheet of paper? Only complaint I have is the paper cone. Hopefully it holds up to the elements and 140 degree heat. Great Speaker.

  The high excursion along with the low Fs made this driver in a 1 cu ft enclosure outperform larger subs I have built. This guy and your 100watt module for less than $100 will wipe out way more expensive units.

  Great small vented design from AudioXpress produces outstanding crisp clear bass using the speaker and an MCM subamp like the 50-6272. Really shakes the floor. I built several of these, one speaker failed after a year, thus the low quality rating. Wait for these to go on sale for <$25 and the amps for ~$50, that's value!
