    These sub's sound amazing.nice deep bass.

  3. Amazing for an 8

    Posted by Garrett, clackamas OR on 27th Apr 2016

    Have this in a slot ported box off a Memphis 1200.1 at 2/3 gain

    It's in a ford ranger.
    Beyond any 8 I have heard.
    Will kill any ten and easily those "super winners" with a 12 on 300 watts an ass whooping.

    I was a bit skeptical at first glance opening the boxes. I never owned an 8" sub and expected it to perform like this. I powered them up free-air and yup i am

  5. Another great sub from sundown

    Posted by Joe on 26th Aug 2015

    Ordered 2 x8 duel 2 ohm both arrived double boxed
    These are some of the most beastly 8's I've ever seen
    Running a incriminator audio 20.1 at 2 ohms and these subs just laugh at it box is about .92 cubes per sub tuned at about
    36hz and these subs get down for sure
    Hand down the best 8 on the market right now

  6. Baddest 8 inch woofer on the planet !!

    Posted by Andre on 10th Aug 2015

    I have 2 of these bad boys on 2500 watts RMS and they take it all day long . I just ordered 2 more for a total of 4 . The air movement is crazy . If looking for big , deep , low bass and space is a issue this is the woofer for you . Don't take my word for it check YouTube .

  7. Remarkable for an 8 inch woofer

    Posted by Mason Williams on 10th Mar 2015

    I received this thing about a week ago, I had one before it was just used and needed replaced. I put this thing in a 0.78 cuft ported enclosure tuned at 38 hz. This little monster gets down and is down right amazing. I have had woofers in many sizes from 10 to 18's, but this was my first eight. I didn't think it would excel the way it does with low end notes nor did I expect so much volume, I only have 500 watt on it now. Would love to hear two of these with proper box, electrical and power to them.
