  • "Great product with excellent value" by greywolf0723 on 9/27/2014

    I purchased a pair of these to replace some tired 15 inch Pioneer woofers. Previously I had built a new box and used the same speakers, but the speakers were old and beat up. At first I was a little disappointed because I was getting very little bass out of them, then I remembered that they have to have some break in time. I have had them operational now for about 2 weeks, and they keep getting louder. As the speakers break in, their sensitivity increases, and movement becomes smoother and less uninhibited. Now they sound great, with plenty of loudness and clarity for movies or music. I will buy this speaker again. I am currently ordering the 10 inch versions for another project.

    Bought these to supplement existing DJ system. I had a set of old cabinets, put these in to see how they would work, they are great. Took my time breaking them in, put 2 per cabinet, 18"x40"x14" with 2 4" ports 5.5" long, crossed over at 700Hz. Nice tight bass, punchy without peaks in response.

  • "Good low-cost organ subwoofer replacement" by jbird604 on 3/10/2013
    Overall: 5 out of 5
    Value:
    Quality:

    Tremendous bass and power, especially considering the very low price. We've used these many times to replace the rotted-out foam-surround drivers in 1980's or 1990's church organ speaker systems. Sure, they're not exact replacements per all the parameters, but they sound great, probably just as good as the originals, and seem to be very durable. I'd rather use these than exact replacements with foam. The efficiency ratings actually don't tell the whole story, as the response curve is weighted toward the bottom and these speakers are louder at 100 Hz than they are at 1000 Hz. My sense is that the low end gets extended by an octave or more when installed in pairs in big subwoofer cabinets like the Rodgers P32. So they pack a lot of punch. Most stock organ amps only deliver 100 watts, so the fairly low power handling figure is of no concern in this application.

    Replaced a speaker in one of my Tower speakers that goes to my Kenwood system! Sounds Great. Good quality construction of the speaker! I would buy them again if I need them in the future.

    I was not expecting much from this woofer, but it really has a kick to it! I put it in a box I had laying around [I normally make custom boxes for each sub] and it really worked. Its a sealed box with ~1.7 cu. ft. Well worth the money!

    I have used this woofer for replacing blown 15" speakers in some LOWER end PA cabinets & Bass Amps. They work fine for that but would NOT recommend them for a DESIGN requiring a driver over 75 to 100 WATTS.

    These make perfect subwoofers for a home theatre application. The woofers are not high end but they do create enough bass in a home theatre setting to impress anybody. I have four of them in a custom 2' by 2' by 4' box built to be in a corner of a room. The 15's put out an enormous amount of sound. I was really impressed by the quality, and sound of a $25 woofer, but you have to remember they're not $200 woofers, and their not going to preform like them either.
