Which gr research speaker should I replace my vandersteen 3a dogs with? 12×18 room.80% TV and movies 25% music

   Either a pair of GR Research N3 TL's or AV3 TL's would be my recommendation. Also, either a pair of N3S or
AV3S with a GR Research 12" servo subwoofer would sound great too.

If you want to match or better the Vandersteen 3A's low bass response of -3dB @ 26Hz you are going to have to use a sub in combination with the main speaker. None of Danny's current models (that I'm aware of) incorporate the subs into a single tower like the 3A's. However, I don't know what the low frequency extension of the LS6 and LS9 is.

If you want to go with sealed speakers you could use a pair of N3S's like Ron suggested and put them on top of a pair of of servo 8"s like rak313 is building in this thread http://www.audiocircle.com/index.php?topic=126451.0 .

If you have the room and want to go open baffle you could mate OB servo subs (either 8" or 12") with the LGK MMTMM speaker being discussed here http://www.audiocircle.com/index.php?topic=126112.0

Lots of options depending on your needs, desires, restrictions
