The most dramatic improvement you will ever make to any audio system is by adding a subwoofer.  Why? Dynamic bass is heard as well as felt! It adds emotion to the music.  A great subwoofer makes an impression on everyone.  Diamond Audio offers five different series of subwoofers.  Each as unique as the people who use them.  From the patented TDX™ technology of the HEX Pro, to the shallow mount convenience of the HEX Shallow,  installers the world over have been raving about the flexibility of Diamond Audio subwoofers for years


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.
