Pioneer SP-FS52 speakers without a subwoofer

[PCFan]

I currently have a pair Pioneer bookshelf speakers on speaker stands that go down to 55 Hz and I don't have a subwoofer due to a lack of space. Pioneer's latest model for floor standing speakers are the SP-FS52 which goes down to 40 Hz, so that's about a 15 Hz improvement in bass performance compared to what I have right now. I also sit about 4-5 ft away from my speakers when watching my TV. I also would think that it would look better to have floor standing speakers next to my TV instead of bookshelf speakers on stands. I have a fairly high-end receiver, a Yamaha RX-V667. Would these floor standing speakers be an improvement in bass performance compared to my bookshelf speakers? Also I was considering the Polk TSi 300's, but they don't have dedicated woofers for bass which the Pioneer has 2 dedicated woofers for bass, and the Polk's are more expensive. Remember, that I don't want a subwoofer but want deeper bass.

I had my brother pick up a pair of the last gen pioneer Towers. The 51's. I had a pair of the 41 bookshelves.
Comparing the two I thought the towers were really great. Yes much more bass and volume output. Supposedly the newer version is even better.

I've listened to the new Pioneer towers and they are quite good for $300 a pair. They will be an improvement from what you have both in terms of sound quality and bass output.

I don't know that there is another pair of towers for $300 that would give you better sound quality. In terms of pure bass output, the Sony SSF-7000 speakers would probably be your best bet for towers in that budget, but I wouldn't be surprised if the pioneers got the edge in overall quality.
