The bass drivers of the Revelator series are equipped with very rigid aluminium diaphragms with piston-like excursion over a wide frequency range. In combination with Scan Speaks low-loss linear suspension and the patented Symmetrical Drive (SD-1), very low distortion, a smooth and linear frequency response and perfect pulse response are achieved.
Characteristics:
* Patented symmetrical-drive drive
* Low-loss linear suspension
* die-cast aluminium basket with rear-ventilated centring spider
* Rigid aluminium membrane (black)
* SBR rubber bead with low damping
* Ferrite magnet drive with rubber protective cap (to reduce resonances)
Use as woofer
* Power handling sinus 90 Watt
* Impedance 8 Ohm
* outer dimension 222 mm
* Basket material die-cast aluminium
* weight approx. 4 Kg
* Frequency range 25 Hz - 1 kHz
Thiele small parameters:
* resonant frequency fs: 23 Hz
* mech. quality Qms: 4.9
* electr. quality Qes: 0.32
* Total Q factor Qts: 0.30
* Equivalent volume Vas: 87.7 litres
* effective mechanical mass Mms: 37 g
* diaphragm stroke +/- Xmax: 14 mm
* membrane area Sd: 220 cm²
* Sound pressure dB: 86 SPL
The woofers were used in a high-end A.O.S "Monitor 45TL-BE" kit. The -3dB point should have been about 35 Hz.
I was always satisfied with the woofers. But I moved to a larger version. M+HT will continue to be used by me.
The price for the woofers are 400.- EUR + 20.- EUR for shipping within EU.
technically perfect. Slight traces of use are unavoidable. Sale of private: No return, exchange

As written I keep M+HT and use a new Woofer: Audio Technology "Flexunit"10C77-25-10-KAP
I also use an active equalization within a closed cabinet.
