Description

Scan-Speak 4.5" Illuminator Midrange
12MU/8731T-00 in 8 ohm
 

The Illuminator woofers are based on compact under-hung motor systems with large neodymium ring magnets. The patent pending motor offers a very long linear excursion together with a very high force factor. The top plate is shaped to “guide” the backside airflow around the motor and with the very open cast aluminum chassis design the driver is virtually free from compression.

The under-hung voice coil is precision wound with CCAW ribbon wire on a titanium bobbin for a low loss yet high power handling design. The vented pole piece has contoured openings to eliminate any hint of turbulence noise. The uniquely shaped top plate and open air frame ensure there is virtually no dynamic compression caused by restriction of the diaphragm back wave.

  • Neodymium magnet
  • Under hung motor system
  • One piece cone and dust cap, full cone technology
  • Very Wide Frequency Response 100-10KHz
  • Patented Symmetrical Drive (SD-3)
  • Low-loss Linear Suspension
  • Foam surround
  • High Output 87dB @ 2,83V

Madisound recommends: a 2 liter sealed enclosure, loosely filled with wool or acousta-stuf.  Your F3 in this enclosure is 185 to 200Hz, depending on the amount of stuffing.

Realism
I used two in a sealed box. It sounds like the performers are right there. Fantastic transparency, depth, dynamics and detail -- very happy with this driver. After about 60 hours they broke in suddenly with a wow factor I didn't expect. I was satisfied before break-in and amazed after.
Each speaker has two 26W/8861T woofers, 2 12MU/8731T mid and one D3004/664000 Berillium tweeter.
