Class-D recommendation

tinear123 OP
Looking for a class-D recommendation. The amp will be from 30 - 600Hz. Everything above 600Hz is taken care of by a class-A amp.

You’ve got the right amp there for the mids and highs, for the bass and lower mids a Class-D is a good cheap choice.

All Class-D’s do bass well between 8-4ohms, (most get current starved around 2ohms) so your ok with your bass units being 4ohm

I would even give a 3000w Behringer a trial for around $420 from major outlets, with those you can usually take them back for a small restocking fee. And with those Behringers they have input level controls so you can get the gains matched with the Class-A you have.

I have a Legacy Audio PowerBloc2 available that would work nicely. 650w into 4 ohms and 1000 damping factor.

I just bought one of these for a 15" sealed box sub I am building to go with my Vandersteens (to complete my bass swarm with the two Velodyne subs I have already)

1,100 watts x 1 (4 ohms)

ClassDAudio.com several options. Solid bass control. Overbuilt is an understatement. Yes, I know. Small operation, etc. Not going to argue with anyone. Have two. Pleased. Buy them new and you will be well within your budget. Great support.

Currently I’m checking out a Class D amp. I have been reading some pretty impressive reviews on the Merrill Veritas Monoblocks.
