In Reply to: We are going to try the 1st order acoustic slopes only, first. posted by Timbo in Oz on September 22, 2014 at 14:44:57:
Sorry, you lost me. The drivers you described can't do 1st order acoustic slopes at 160/170Hz due to their natural rolloffs. Do you mean 1st order electric crossover combined with the natural rolloff?
I find with integrating bass drivers and midbass / fullrange drivers, it's not always as difficult as it sounds like on paper. Then again, I don't shoot for a *naturallly* transient accurate response. When doing digital I can use forward/reverse phase correction (group delay correction) or FIR filters. With analog I usually overlap electrical filters with acoustic rolloffs and shoot for 3rd or 4th order.
To be honest, I used to be very enthusiastic about transient accurate systems, but now it's not so much of a deal breaker for me.
Some people have problems with "absolute polarity" and other such delicacies - and switch polarity to and fro between recordings to figure out which is right. Others just say non-TA speaker systems just don't "sound right" and that only dynamic TA designs or planar speakers will do. Often the bass modules added to planar speakers are not TA. Many say TA is only important in the midband.
I really don't think you'll have too much trouble.
Also - why voltage match the amps? Are the drivers gain matched? I usually null the gain difference between drivers *using* the amps rather than add passive components for padding down drivers. Anyways, I was just curious about that. Gain matched amps didn't seem to be a requirement here so long as the final gain of each "cabinet" is correct.
Cheers,
Presto
