The Heavy Duty Street Series 6.5 inch 350W Subwoofer improves on its predecessor in terms of build, sound quality, heat dispersion, and frequency response. Note: Because of its smaller form factor, the 6.5-inch version specifications vary from the rest of the series. See the specifications tab for full details. The HDS2 series is an affordable option for your daily-driver car audio system build.
First, choose a sealed, ported, or band-pass enclosure. Once you decide on an enclosure option, pair your sub(s) with the appropriate S Series monoblock amp. From there, enjoy easy wiring thanks to 10 AWG push terminals (14 AWG direct leads in the 6.5 and 8-inch models). Soon you'll be on your way to a dramatically enhanced listening experience.
As with any SoundQubed subwoofer, proper break-in is key to enjoying long life from your HDS2.2 sub. Make sure you follow the steps to loosen up the suspension before pushing these subs to the limit.The HDS2 series uses a 2.5-inch diameter, four-layer, copper dual voice coil with a conical back plate for longer travel. High-temperature adhesives and high quality coil wire guarantee reliable long-term performance and a healthy level of bass! The HDS2 series feature cast aluminum frames. This upgrade provides better heat sinking and increased excursion over stamped-steel baskets. A softer three-piece spider system achieves enhanced performance and lower tuning. An Extended Range of Motion (EROM) surround profile keeps your cone diameter as large as possible while allowing for long, controlled excursion. The EROM profile gives you more cone area, greater stiffness, and lower mass for more accurate coil signal response. The HDS2 has a non-pressed, fiber added cone for maximum rigidity and long life.
