Bookshelf speakers: Micca MB42X/Infinity Primus P143/Pioneer BS22/Sony B1000
I'm looking for a set of bookshelves to upgrade from my standard TV speakers...I have to place them on a shelf mounted underneath my TV and have a little over 7 inches of depth to work with, the speakers are going to have to be placed against the wall or very close to it.
Considering that I'm connecting straight to the TV and that the speakers have to be placed against the wall and without a sub, which of the following should I go with?
1. Sony SS-B100: 5.25 inch speakers and front ported, ok reviews.
2. Infinity Primus P143: 4 inch speakers and front ported, good reviews.
3. Pioneer SP-BS22-LR: 4 inch speakers, rear ported, good reviews.
4. Micca MB42X: 4 inch speakers, rear ported, reviews seem to love these.
I'm mostly concerned with musicality and bass response considering that I'm going without a sub. The Miccas seem to get great reviews, but I'm not sure if I would be better off with something like the Infinity due to the front ported design considering necessary wall placement. Then there's the matter of the Sony speakers having larger speakers than the others...
Any input or advice?
