Are there any bookshelf speakers that sound good on a bookshelf?

Vandersteen VLR CT.

Had a pair for about two years now and really like them. (Paired with Ayre integrated.) They are especially good at low to mid volume listening (about 85dB and below.) Room is 20x14. In fact, I plan to go Vandersteen when I step up to floor-standers, based on my experience with the VLRs. Exceptional.

Proac Response 2 or 2R.   Great speaker, with a front port.   In my experience, anything with a rear port needs a foam plug when located in a bookshelf, and then the bass response rolls off, and then life becomes a little less enjoyable.  I’m sure there are exceptions, but that’s my experience.  Of course imaging will suffer with a bookshelf location, but if this is a “real world” situation not involving a dedicated room, then I have had the best luck with the Response 2’s.   

Save lots of money try the KEF LS50, awesome speaker!!!

Dynsudio secial 40 is around 3500..its.not several thousand dollars. 

I overhauled my office last year, created a perfect triangle with bookcases opposite my desk, my chair/monitor dead center, primarily streaming Pandora music or YouTube video from PC.

bought a pair of bookcase speakers (no ports, shallow depth) to mix with my existing Velodyne Sub. I am extremely happy, added a TT and R2R in the system.

After research I decided to limit my search to models with 6-1/2" drivers, a bit more directional bass, then let the sub blend in.

I ordered two pairs, 1 for my shop, another 'better' for my office. I ended up using them opposite to that.

eBay, vintage B&W DM100i, horizontal on shelves ear level. (they say 6" piston size)

A crossover in the sub removes the low bass frequencies makes it easier for both the amp and the bookcase speakers to do a great job. The speakers will not be in a self-made cloud of bass blob.
