Thanks Keith @Purité Audio

A couple of quick facts while still in prototype phase:
  • Basically a scaled-up design of Model M1 as a standing speaker, so wide baffle and very shallow: 1100 x 480 x 185 mm (apx. 3.6 x 15.75 x 0.6 ft.)
  • It shared the same 44 mm (1.75") titanium compression driver as Model M1, but within a bigger waveguide.
  • Midbass driver is a 250 mm (10") low distortion design with an Nd-motor in a closed cabinet. Because of it's linear motor and suspension design (verified via Klippel LSI) is can also deliver quite bit of bass.
  • Additional bass is a 300 mm (12") mounted a the lower back in a ventilated cabinet (2x aerodynamic optimized ports, each located on the side wall). We haven't decided yet which driver, but there are two left. Both share the same impressive specs, like a 100mm (4") voicecoil, +/- >10 mm xmax and a 200mm (8") magnet. Each driver can deliver 105 dB SPL @35 Hz, which gives you plenty of headroom and should be sufficient with any music and non-artificial content.
  • Similar to Model M1 the overall concept is to shape directivity at every frequency in combination with the waveguide (hights), wide baffle (mids) and the cardioid pattern (bass).
  • Furthermore there will be patterns to help you integrate bass into your room.
  • Electronics will be integrated within the speaker this time, expect apx. 1000W SMPS classD per loudspeaker (Pascal again).
  • Since we use the same DSP platform like Model M1, most filters are FIR based and linear-phase. Also there is advanced limiters and dynamic-EQ, which give you an extra turbo when you need it.
I will post some update form time to time.

I know that you are the one making them, but I don't think they measure six feet in any direction.

And measurements matter here! :)
