My HT Sub is from VMPS. I have the Original sub in Piano Black with the Mega woofers, improved wire, and interior sound coating. The sub has a single 12" Carbon woven woofer facing forward, with a Paper 15" Radiator facing the floor. On a scale of 1-10 I give it a 9.5! Only taking off for its size. Not all women would accept this table size woofer. In fact I now keep a blanket folded on top of it, as people tend to walk in and sit down on it lol! Musically it ROCKS! Many people use this woofer who use ribbon speakers, as this sub does better then most in keeping up with the fast ribbons. Its a must for Magnepan users. My woofer is tuned to 18hz, so as you can guess... It goes VERY low. I drive mine with a Bridged Rotel Amp that gives it around 400 Watts. I bought mine silightly used. They can be bought pre-made, with a kit but not assembeled, Or speakers and plan only, you build the cabinets yourself. The site is
