B&W Signature HTM
¥ 600,000 (1 unit, released in November 2001)
Commentary
This is a center speaker of the Signature800 series developed as a B & W 35th anniversary model.
Two 16.5 cm paper / Kevlar / cone type woofers are installed in the low range.
The mid-range is equipped with a 16 cm diameter Kevlar fiber cone FST mid-range.
This unit uses an extra-large neodymium (NdFeB) magnet with a high magnetic force for the magnetic circuit. The outer diameter of the magnetic circuit is slimmer to reduce back reflection. In addition, an extra-thick plate and short voice coil are used. By making the plate extremely thick relative to the voice coil winding width, distortion at high volume and modulation due to voice coil magnetic field are reduced.
A 2.5 cm metal dome type tweeter is installed in the high range.
Silver, which has lower electrical resistance than copper, is used for the cap of the pole piece to suppress the inductance of the voice coil to the ultra-high frequency range, expand the ultra-high frequency reproduction limit, and reduce harmonic distortion.
The enclosure is round in shape, has a matrix structure inside, and has a high-gloss Gray Tiger Eye wood finish.
