Diamond D308
DIAMOND - D308D2/4
8" Dual Voice Coil Subwoofer

Like our D3 amplifiers, our D3 series 2 subwoofers are the definition of value and performance. With large 2.5" dual voice coils, available in 2 ohm or dual 4 ohm, beautiful polished back plates and dual spiders, with woven tinsel leads, these subs have features found in much more expensive models. All D3 series 2 subwoofers handle up to 400 watts RMS. Our proprietary aluminum dust cap pulls heat away from the voice coil so they play louder, longer.

These woofers work well in sealed enclosures but put them in a vented one and they absolutely excel. Visit an authorized dealer today to see and hear for yourself.

Original D3 still available in 8" and 15".
