Thanks Keith @Purité Audio
A couple of quick facts while still in prototype phase:
I will post some update form time to time.
- 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 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 know that you are the one making them, but I don't think they measure six feet in any direction.

What is mid bass displacement?
Sry just curious. How deep you have to go with the tweeter that you still have good dircetivity match with the 10inch?? And why you changed the active system to a active speaker?
I mean displacement overall , but most speakers I owned lack “slam” for lack of a better word the typical 6,5” speaker does not do that![]()
Roland, looking at the position of the 25 cm mid unit on the front, I expect to see some boundary effects (Allison Effect) in the upper bass lower mid range region due to the floor. I’d estimate 125-200 Hz. Will the mid range be rolled off to the woofer so that it does not operate in this region, or are you using some other means to avoid this problem?
The speaker is very thin, so will you be adding a base or outriggers to improve stability ?
Lastly, may I urge you to build a convolution engine into the speaker’s firmware so that it can run filters? D&D 8C can run REW generated filters, Genelec and Avantgarde Zero offer their own software options. All 21st century DSP speakers should have this feature, IMO.
