For bookshelves with a wood finish that are interesting, look at Revel PerformaBe M126Be in Walnut. Beryllium tweeters that are airy without sibilance and good mids and clear punch in the lows down to about 80-60 Hz depending on room gain. They look gorgeous with a high-end furniture quality look. I run with subs which you’ll want with any bookshelves in a large room.
Have some fun with bookshelf monitors!!
This is ANOTHER what speaker should I buy. But here is the thing. I might have a speaker problem......
I currently own the following speakers: Dynaudio Evoke 50s (my main room) driven by Prima Luna, Watkins Gen 4 (secondary room) driven by Cary amp, Harbeth P3ESR (office) driven by retro Grant Fidelity tube amp, and Wharfedale Evo 4.2 (home theater) driven by an NAD AVR. If you ask my wife that's about seven too many speakers.
BUT
I have a new large room, lots of glass, 10' ceilings, and have to use an NAD 3050 amplifier. Speakers have to sit on a bookshelf, have a wood or white finish, and most importantly be interesting!
SO...
with a $5,000 top end (and goal to be half of that) tell me what you buy.
