Product Sheet

Thanks to a long work about drive units, Supravox’s engineers designed the majority of their loudspeakers without filtering which is the best way to optimize a exceptional sound reproduction and natural restitution.

This TQWT (Tapered Quarter Wave Tube) enclosure is a full range enclosure equipped with a 215 Heritage bi-cone EXC.

Alnico, one of the oldest magnet formula with its Ticonal cousin, offer high remanence, almost perfect temperature ratio, very high usage temperature of 450°C, but low coercivity for old and usual grades.

It’s a very good, and expensive, magnet which needs careful design of the magnet assembly to exploit its qualities.

The all-new loudspeaker is based on the original T. 215 SRTF diaphragm from the 1960s. We have indeed developed this loudspeaker by starting from original models in order to find the sound qualities that have satisfied music lovers over the past decades.

We designed this driver around our classic 215 aluminum frame.

The underhung motor field has been optimized using FEA software, its high manufacturing quality is ensured by an CNC lathe.

For this 215 we have designed a new lightweight coil made of copper-plated aluminum wire on Nomex former.

A thorough study of membrane treatment ensures a linear, and very extensive, response.
