I would go with a stand mount 2 way if it were me. I have a big system in a big room and also have had many systems in my smaller bedroom. I am always amazed at how much bass a small speaker can pump out in the bedroom compared to my giant speakers in a huge room. I've had floor standers in the bedroom and they've always been a little boomy sounding. With a space that small I wouldn't bother with a bigger speaker they aren't made for that kind of space. Lots of exciting choices for 10K!
Good Used Speakers ($8K-10K) For A Little Listening Room
I know that this is a tough one, because speakers are so subjective. My dedicated 2 channel listening room is only 10ft x 10ft. I listen to mostly jazz and rock. I currently use a Plinius SA100 Mk III (recapped and upgraded) driving Joseph Audio RM25XL's. I'm thinking of upgrading and was wondering what speakers would be a good upgrade for a small listening room. I like the Joseph Audio sound, but want more. I was thinking of Pulsars or maybe Perspectives. First, is my room too small for floor standing speakers? Second, what other speakers in the $8-10K range used would be a good fit in a small room?
