Here is Atlas PD-5vh http://www.atlassound.com/compression-driver-40w-16ω Does this mean the B&C DCM50 actually needs less attenuation than a k55v? And my usage will be less than 10w power handling 90% of the time. More thoughts welcome

Thanks Dean. But per B&C website, the DCM50 has an efficiency at 108.5db/1w, and K55v is 110db/1w (as per Atlas website). Will this be close enough as an "approximate drop in" replacement? http://www.bcspeakers.com/products/hf-driver/2-0/dcm50

Thanks Dave! About your comment on DCM50 being too sensitve to use with Type A, how about using a lower tap on the autoformer? (In my case it is a 3636 transformer from Bob Crites with 1-18db attenuation setting)?

Any advice will be appreciated

Hi guys, New here. Have been tweaking my La Scala the last few months. Bought soldered lig version K55v, replaced the mid horn with Azura Le Cleac'h flare round, tweeter replaced by B&C DE120 with a cheap PRV tractrix waveguide (us$8 each on Parts Express). I made a new Type A crossover using russian K75-10 pio capacitors. I am curious about a better mid driver, and have been thinking about the B&C DCM50. My listening space isn't very big, neither do I listen to very loud volume in most instances, so I guess the DCM50 should still be ok, although I may make another crossover similar to AlK's Universal or John Albright's DHAX2. My question is: should I get the 16ohm or 8ohm version? For example, in the Universal there is a 10ohm resistor across the autoformer which I think is to flatten the 16ohm (of k55) to something around 8ohm, and this necessitates a change of high pass capacitance from Type A's 13uf to 48uf. So If I get a 8ohm DCM50, the 48uf would not be correct and need to be adjusted. I am hoping someone can throw a torch here. Thanks

Hi Dean! I received your k55v. They work magic! Thanks, despite the bit of waiting.

Hi Dean, have you shipped my pair?
