IQM

The newest WHT IQM series featuring 8" WHT woofers with 20 Ohms impedance and triple winding voice coils. Two or three driver units can be combined to work together. The IQM bass response can be tuned with the adjustable passive bass control system.

 

Changing the room bass response with acoustic panels can overdamp the midrange and treble frequencies. IQM offers a simple and very effective solution.

 

By closing or opening the IQM ports only bass response can be adjusted without affecting midrange and treble. So called "close box" can be created by closing all three ports making the IQM a very flexible speaker. With 97dB efficiency IQM represents the perfect match for tube and solid state amplifiers.
