Recommendations Please: Bookshelf Speakers no Larger than 7"x12"x8"

thats tough...maybe splurge and get the audioengine hd4s or something

Triangle?  front ported  the ones smaller than the Comete

You might want to see if Best Buy still carries Polk T-15 bookshelves.  They’re 7”w x 10.5” h x 7.5” d.  Definitely not the pinnacle of high performance.....I found them to punch well above their weight though and enjoyed listening to a pair of these in a 14’ x 24’ art studio for awhile.  Not rear ported and, if they’re still being offered, I would suspect they can be had for less than $100 US, new.

ADS L400 

I should clarify. I am wanting to spend around $200 for just the L and R speakers. Also, I could extend this up to, say, $400 if necessary. I am not including the sub in this price requirement.
