MiniDSP 2x4HD used with a high efficiency system

belyin... Once I get farther into the tuning I'll give you some feedback on the Voxativ AC-2.6 drivers.  I do like very much the AER's but have had a hard time keeping them alive for any reasonable length of time.  I looked at a number of driver options.  The Voxativ line spans from ~ $1.5k/pr to of course $25k/pr much less than the AER DB-2 or 3.  The AC-2.6 is the middle 8" and lists for a sensible $3.7k/ matched pr.  For the base I am using Bert's BD-15 Reference Compact design at present but am considering change.  I really like the transient response of the La Scala "W" horn.

tinear . . .  I bought my AER's lightly used quite a while ago. I think they correspond to DB-1 in their current line-up. Do you know anyone in the States who can refoam them? I saw a post somewhere recently that related someone's effort to do it themselves, and it sounded daunting. I have never heard true horn-loaded bass in a home setting--as always one picks one's compromises! 

I heard of someone servicing AER in the DC area a while back.  Let me see if I can find the info.  The tolerances of these drivers is very tight.
