The 6.5 transducers Quantum Series 6.5"(4 ohm) was designed for demanding bass and midrange applications. It works equally well for hi-fi level car audio.

Features:


1. Alum field-stabilizing ring inside magnet assembly for reduced high-level distortion
2. Vented voice coil former for reduced distortion and compression
3. New vented chassis for lower air flow speed reducing audible distortion
4. Heavy-duty black fiber glass voice coil bobbin to increase power handling and reduce mechanical losses resulting in better dynamic performance and low-level details
5. Large motor system with 1¼" voice coil diameter and 90 mm magnet for better control, power handling, and efficiency
6. Black magnet parts for better heat transfer to increase power handling
7. Linear suspension with specially designed Conex damper (spider) for long durability under extreme operating conditions
