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

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.

I have SVS Ultra bookshelf speakers with a SVS sub and they kick butt.
