Speakers that sound great in terrible rooms

Smaller is often better with speakers in rooms with bad acoustics.

My wife's sunroom is pretty bad.   I've tried a lot of speakers in there but the tiny  Vanatoo Transparent 1 Encore speakers on Isoacoustic stands in there really shine.  I think the built in signal processing helps.

That’s why there are headphones.

I unfortunatwly have no personal experience with Ohm Walsh speakers (yet,) but I'm surprised no one else has mentioned them. (At least I didn't spot anyone mentioning them during a quick skim of the responses.) One of the most commonly praised aspects of the Ohm speakers is that not only are they one of the few speakers that sound good in live/untreated rooms, but they are actually meant for such rooms!

Ohm Walsh are always a good choice in general IMHO regardless of room acoustics, more so than more directional designs.

Just going to say give these guy's a shot. Dumped my Sonus Faber Olymlica II for the the Celest and zero regrets and this is an American Company that is run by musicians.
