    I was going to give this JBL Subwoofers 4 Stars... but for the price I got them 2 for $65 it was a great deal. The Subs Sound good... Not the loudest but good bass. Overall it's a great deal if you can get them on sale.

    Not Correct specs

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Well, pretty disappointed not sure what the actual specs are for these speakers. Site says 300w box says 250w site says 23HZ for the frequency response box says 35Hz. I'm more concerned about the frequency response for the low end sound then the wattage. Not sure i want to keep these. please change the site to be accurate. a lot of people are going to be getting a different product then they think they are.
