Peavey SP 4BX - Dual 15 Inch - Three way Cabinet - 2000 watts has an ingenious 3-way design that improves low-end performance and produces clearer sound in the high frequency range!
This quasi three-way enclosure has two 15 inch Peavey Black Widow® speakers capable of handling up to 4000 watts peak power and have field replaceable baskets for quick, easy repair. Peavey engineers have designed a much more efficient crossover that directs low frequencies to both woofers while limiting mid-range frequencies to only the top woofer. Upper-mids and high frequencies are handled by an RX 22 titanium driver that is ferrofluid cooled for maximum tweeter performance and longevity. Peavey's exclusive Quadratic Throat Waveguide technology actually reduces horn distortion and aims sound directly at the audience, not over their heads. Rugged hardwood construction, utilizing extensive internal bracing produces tighter bass response while significantly reducing the cabinet weight. Finished in a durable thick black carpet the SP® 4BX has heavy-duty handles and kick back wheels for easy transportation.
