Proac Response D40R or D48R

cmach, is the D-48R a significant step up from the D-30R?  I am considering the D-30R.

A new version is on the way the D30S that use the same revised new driver of the D48.
 The D48 must be significant step up from D30 due the extra driver ; deeper bass and more clarity and control in the mid.

Randyhat,

If you have the room size for a D-48R I think its worth the extra $$. It takes all the strengths of the D-30R and expands on them. Better dynamics, more resolution and a completely  effortless sound. That being said, for my room the D-30R was the better fit and I've really
been impressed with it.

Kclone my room size is 16 x12.

I think it's better to wait for the new D30SR.

itzhak1969, I pulled the trigger on the D48s, but I won't be able to give you impressions because it won't be here for a few weeks (ordered silk white, takes awhile).   Sounds like you are thinking about the D30SR anyway.  Good luck in your search.
