Frequency Response:

38Hz-35Khz +/- 3 db

Impedance:

8 Ohms nominal @ 1000 kHz- Very easy load on any amplifier including low powered tube amps. See Impedance & fantastic phase curves below

Sensitivity:

88 db (1 Watt, 2.83 V @ 1 Meter)

Bass/Midrange Driver:

7" Carbon Graphite Fiber/Paper Pulp composite cone with non-resonant low loss butyl rubber surround & Kapton voice coil former & die cast frame with massive magnet, bass reflex loaded- rear port.

This unit is an improved version of the highly praised 18W/8545-00 midwoofer, where a new aluminum chassis, an updated cone and a new spider as well as a few other details are introduced, these updates improves mechanical stability and sound performance.

High-quality magnet system design with patented Symmetric Drive (SD-1) continues to be a key feature. The magnet system is the new SD-1 system which eliminates modulation and dynamic distortion, as well as clipping distortion created as it exceeds its maximum linear excursion.
