    Can't really explain how good these are!...but I'll try.

    Overall: 5 out of 5

    Background and Setup: I thought of building 2 subwoofers for my home theater and getting rid of the bulky Polk 12" subwoofer. Then I built 2 separate ported boxes for these speakers and put near the front stage. Have it connected at 4ohm configuration with the Parts-Express SPA250 plate amplifier.

    Now to the actual review: Right off the bat, there was a tremondous improvement in the mid-bass region exceeding any bose setup you see in Best buy. Then after hearing some familiar songs I felt, there was a decrease in the real low levels(under 30hz).

    So I went back and connected my Polk 12" behind the seats with 180 phase shift. Then I blended all the speakers with the correct crossover.

    These speakers at 200Hz crossover, Gain set at middle. Front Stage. 0degrees shift
    Polk PSW505 12" subwoofer crossover at 90Hz, gain set at middle. Behind the seats. 180 phase shift.

    I cannot imagine it would be such an improvement!! I realized what I was missing all these days. Every beat feels like coming from the stage and ending behind us. Crispness and loudness, precise beats due to the comparatively small drivers.

    Without a doubt, I would recommend these woofers anytime.

    These speakers are definitely worth the money - Frequency is 28HZ to 2.5KHZ - speakers actually have a 2 inch voice coil and that makes the speakers 77% better than listed. It is very doubtful anyone can find an 8 inch, 8 ohm speaker that works better than these. MCM this was a great investment for me.

    Using them in a 400W Subwoofer ... sounds better than the original speakers
