Part of good <$100 sub for home theater, 11/23/2007 10:52:40 AM

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!

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.
