    • "Wow, more than I expected" by robotundergroun on 11/1/2012
      Overall: 5 out of 5

      Was mulling over if I should refoam my old Optimus 12" PRO-SWS 501 subwoofer. Since the driver is proprietary, I had trouble finding a surround that would work well. I found this driver while searching for dual 8 ohm subs here and Parts Express. This thing is pretty beefy as far as home speakers go. You don't need something crazy like a car woofer and car subs don't come in dual 8 ohm configurations. Drops in with no hole mods. Sounds SO MUCH BETTER than the original! The bass is more pronounced and can really be felt. The sensitivity is not the same though. A bit lower than the original driver... However due to the heavier motor structure, I decided to dedicate a receiver to it and pump it up to my taste. Thank you MCM! Great choice and a great price.

    • "Good middle of the road replacement" by Skyhook55 on 7/9/2012
      Overall: 4.5 out of 5

      This speaker replaced a blown woofer in my Cerwyn Vega full range car enclosure. I had an amp blow and burned out the OEM speaker. I chose this one as a suitable replacement, and the 8 ohm voice coils will load the new amp less, but at the cost of slightly less db energy. The first woofer MCM sent was defective. The voice coil was rubbing on the magnet structure. They graciously exchanged it for another one. They fully covered my UPS charge to return it as well as UPS charge for the new one! SUPER job MCM! The new speaker is fine and sounds pretty darn good too. A good speaker for smaller ported enclosures.

    • "Great woofer for almost any application" by ryonemoto on 10/16/2009
      Overall: 5 out of 5

      To give you an idea of the versatility of this woofer, I'm currently using it on my PA floor monitor speaker that doubles as a subwoofer. Granted that this woofer was designed for home or automobile application, it none the less has flexibility to be used in a PA bass cabinet application due to its unusually high efficiency (96 dB/ 2.83V/ 1 meter). I had this idea of PA floor monitor that doubles as a bass amplifier when I saw Fender's Bassman 150 combo amp. This compact 150 watt bass amplifier impressed me in that I could hear strong bass output 70 feet away from the stage when I'm mixing FOH. That's with a single 12" woofer. So I figured if I can find a subwoofer with good efficiency and small Vas, I could build it into a floor monitor, and it will serve dual purpose as a floor monitor/bass amp. I first looked at Pyramid 1254, but it was out of production. Then I found this woofer. It was perfect. I put it into a 1.5 cu. ft enclosure, and tuned the port to 36 Hz. With this setup, the bass is down 3 dB at 50

    • "High performance, moderate price!" by bucksnort on 5/22/2009

      I used this woofer in the very first sub/sat system that I ever built. I calculated the cabinet to be 3.41 cu. ft. and it measured I.D.= 12"w. X 15"d. X 32 3/4"h. I used dual ports, each one measuring 2"dia. X 5 1/4" long for an F3 of 35 Hz. You can trust me on these calculations; I have extensive knowledge in loudspeaker design and concept. I crossed the voice coils over at 80 Hz each, using a 12dB high and low pass filter, although a 100-150 Hz crossover may work every bit as well. This woofer kicks ass and will shake the room and vibrate the furniture... really! Although it will not dig deep into to 20-plus Hz range, at 35 Hz it will perform impressively well with music or video. To be honest, I was completely blown-away by the performance of this seemingly "generic" woofer!!! I would highly recommend it for any application you should choose! For the money, why not just buy it and experiment with your own personal design... you can't go wrong!
