      Those other guys don't know what they're talking about

      Overall: 5 out of 5

      Anyone who has any trouble with the volume or bass levels from this speaker is because they dont have an adequate power source. This speaker takes a lot of power to move the cone, especially at an 8 Ohm resistance. I decided to use this with the 100W mcm subwoofer amp, and it takes full power, with very impressive bass. Best $22 subwoofer money can buy. These speakers are very rare now too. Pyramid speakers are discontinued. These will soon be collectors items

      Look the part but do not perform well at all. Not efficient and weak bass

      Overall: 1.5 out of 5

      I bought these to replace cheap 12 inch Radio Shack monitor woofers that had a simple high pass crossover. I added a 2k crossover and these woofers but was surprised to find the new speaker/crossover required a large amount of power (200 watt ch 8ohms Crown xls) to make any sound at all. I removed the crossover and replaced the high pass and no change. These speakers while rated at high efficiency are simply NOT and the bass is almost non existent. I don't use them at all until I can replace them. the original radio shack speakers were pretty powerful compared to these :-c

      Worst than I expect

      Overall: 1 out of 5

      I buy 2 of this to replace a damaged OEM woofers and really disappoint me. At around $20, I dont expect too much from this woofer but once installed in the box it really disappoint me. I can't say anything good of this "Pyramid" woofer. Not even the price because you can find a really good woofer at a excellent price from "MCM Audio Select" brand.
