Customer Reviews
4 out of 5 (3 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "very impressed"
Overall: used a pair of these in a DIY cab, copy of EV T-18s. Wow, they punch!. the cab, by default has a natural roll off somewhere around 40-45 hz, leaving an open road to kick drum and bass freqs. broke them in at a 6 hour festival a few weeks ago, and these things took all 1200 watts/each i threw at them with ease. perfect for rock, country, pop bands without alot of sub bass to reproduce. will be buying more to add to the stack. ZZounds were wonderful as always!
Style of Music: christian rock, P/W, metal

1. zZounds offers the industry‘s most musician-friendly payment plans

zZounds offers a variety of Play as You Pay installment plans that allow you to get the gear you want today. While our competitors might offer house credit cards that require you to fill out an application and pass a credit check, our payment plans are easy to get, simple to use, and, best of all, accrue zero interest. Unlike those house credit cards that can leave you vulnerable to exorbitant interest charges once the promotional period ends, we never have and never will charge interest when you take advantage of one of the zZounds Play as You Pay plans.
