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.
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 new Alnico driver, developed under FEA software, is designed around a 1 kg central magnet of Alnico 5. This arrangement allows 100% of the magnet’s energy to be captured.

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