The Prime Pinnacle is a pretty good speaker. The Polk LSiM speakers are a very difficult load for an amplifier, so you should have a good amp before considering those. Your Pioneer AVR won't cut it. I did hear those Boston Acoustics speakers a few years ago and I liked them. The JBL Loft speakers probably aren't terrible, but I don't know much about them. The Definitive Technology Speakers are expected to be used in a larger room than what you have due to the bipole design. I don't that would work well in your situation.\n\nOne thing you should consider is the tweeter height versus your listening position. If you do go with a tower speaker, make sure the height of the tweeter is roughly level with your ear height when seated in your listening position. Measure your ear height at the position that you normally listen to your system at, and see how high these towers are and where the tweeter is mounted on the tower.\n\nBut again, I don't know why you are so hung up on these tower speakers. Their advantages over bookshelf speakers are headroom and bass extension. You won't be taking advantage of the bass extension since you are using subwoofers, and you certainly won't be taking advantage of their dynamic range since they can get way louder than you would be able to tolerate at such a close distance. Bigger isn't necessarily better with regards to loudspeakers.\n\nThanks for the info\n\nThere are 2 main reasons I want towers, I like how towers look as they are more imposing than bookshelf speakers and they are much easier to set up for me since I don't have to get stands for them.\nAlso thanks for the tip about the tweeters being ear level, I'll have to measure my current ones as they are about perfectly ear level.\n\nThis may be entirely subjective but I noticed on my brothers system he had bookshelf speakers and tower speakers that were from the same brand (and model) and the towers also seemed to make a "fuller, smoother" sound.
