Can you provide some insights about the Mummy’s sound ,etc and what you drove them with?
Sorry for the late reply. I drove the Mummy’s with my current gear, a Belles SA-30 class-A poweramp and SOtM sDP-1000 DAC/preamp (and a PC-based source with an Audiophilleo 2 + PurePower USB-S/PDIF converter + JRiver MC25 DLNA and NAS drive), and before that also a NuForce poweramp and DAC.
The Mummy’s were rather coherent sounding and versatile speakers. I really liked the OSWG waveguide fitted with the BMS 4524 compression driver and what it did from some 1,6-1,8kHz on up (an impressive feat by the 12" Beyma 12BR70 to go this high in the decent manner it did). Apart from slight material resonance/signature some of the least horn-sounding variants I’ve heard, with a rather "mild" imprinting. In its specific MkIII implementation a bit tipped-up in the top end, slightly recessed central mids, and a relatively dynamic midbass though fattening up a bit towards the port tune. Nice, sphere-like soundstage. I preferred blocking one of the two ports in each speaker.
