Scanspeak 15M/4531K-00 5 ½" Paper Cone Revelator Midrange- 148mm- 4 ohm
Spec Sheet PDF
Features slit-paper non-resonant cone and dust cap structure, dynamic linear suspension, SD-1 magnet system, "Grasshopper" cast chassis with maximized air flow, glass fiber voice coil former and resonance terminating mounting system. The 15M/4531K is intended for use as a midrange, with a usable frequency range between 100Hz and 6kHz. As you can see from the response curve, this speaker has a lot of energy in the upper frequency range.
The Revelator woofers and subwoofers feature very rigid cones in paper or aluminium that operate as a piston over a wide frequency range, in combination with Scan-Speak's low-loss linear suspension and the patented Symmetrical Drive (SD-1) results in very low distortion and a smooth and well behaved frequency response as well as perfect transient reproduction.
- Excellent Midrange Reproduction
- Sliced Cone (Controls Cone Breakups)
- High Output 90dB @ 2,83V
- Patented Symmetrical Drive motor design
- Low-loss linear suspension
- Die cast Alu Chassis vented below spider
We'd suggest 2 to 3 liters, enough to enclose the midrange, well stuffed and damped. F3 about 140 Hz. Sample internal dimensions 7" x 7" x 4.3" deep.
