I’m about to push the button to get 2 SVS 3000 micros to add to ATC SCM40s.

The SB1000 Pro is only a little bigger, goes lower, and is cheaper if you can deal with its larger size.  That’s all I got. 

Excellent stuff, and I totally agree the subs will bring you to a level you never knew was there — probably about the best absolute upgrade you could make.  Of course, there’s always power conditioning, power cables, interconnects, digital and erhernet IC, room treatments, etc.  It never ends, but I have a feeling you know that and should’ve never said anything will “finish things off” for you.  Silly person.  All you did was upset the audio Gods who will now strike down on you with furious anger and take even more $$$ from you.  Deep down you know I’m right. 

Congrats!  I’m sure you’re gonna be thrilled.  Please follow up with impressions if you could.  BTW, SVS has excellent customer service so you might want to describe your room to them and they’ll probably cut down your tinker time considerably with some helpful tips — that’s what I’d do.  Once you get them dialed in let your wife listen to a good recording and while it’s playing turn the subs off and look at her reaction.  She might end up really loving those small boxes.  And if she cuts you some slack with this audio silliness I’d say you got a good one and a keeper.  Love your speakers BTW.  Are they version 1 or 2, and what amp are you driving them with?

Agree the subs likely need some time to loosen up and settle in.  

Congrats, and I’d buy the wife some flowers for being such a good sport.
