[QUOTE="Michael John, post: 80049, member: 830"] Re: Coaxial Wedge Collaboration I completed a 2nd pair of wedges based around the B&C 12FHX76 and this time opted for biamping. (My mistakenly said 12HCX76 in the previous posts.) Today I created DSP settings and ran one side by side with the previous BMS 12CN680 wedge. The passive BMS was already fairly flat. I EQ'd the B&C quite flat and close to the BMS. Overall I really like both. They're excellent drivers, don't need much EQ and sound very clear. Some brief observations. The B&C horn (60x40) horn is noticably more sensitive to moving off axis that the BMS (80x60). I think I prefer the BMS. The BMS magnitude response has a 5 dB bump at around 16.5 kHz. With both drivers broadly EQ'd flat, the BMS is higher above 16 kHz and to me it's subtle but audible. (I was reluctant to push the B&C with a filter to get a closer match.) I think I prefer the extended HF of the BMS and there's something nice about it's smoothness. Both cabinets are ~24 litre and have ports tuned at about 60 Hz, but the BMS extends just slightly lower in frequency: in measurements and faintly audibly. I only listened at low to moderate levels. When I get some loud time, I'll post again. [/QUOTE]
