IDQS Subwoofers redefine the performance standard for small thin mount subwoofers. With a very high linear excursion created from the precise motor and suspension design, the IDQS Subwoofers provide you with great sound quality, power handling, and accurate low-frequency reproduction in the smallest of spaces.

Features:

• High Excursion Design: Allows acoustically linear bass output at all rated power levels.
• Parabolic Santoprene Surround: Ensures cone linearity and control.
• Poly/Mica Cone: Delivers strong, distortion-free bass reproduction while still capturing all the musical nuances.
• Nomex Spider: Provides consistent control throughout the piston range and the life of the woofer.
• Poly Carbonate Neck Joint: Handles more raw power without mechanical failure or flex, while isolating heat from the BASV voice coil former and the cone.
• American Made Flat Wound Extended Voice Coil: Offers higher magnetic flux (strength) and more voice coil "traction" in the magnetic gap, with over 1.75” of linear travel in the magnetic gap.
• Extended Y-35 Motor Structure: Enables the voice coil to move freely without mechanical bottoming out while producing a powerful flux field.
• Field Replaceable Cone Assembly: Can be changed in 10 minutes using only 16 screws and alignment shims provided in the recone kits.
