I agree with Podeschi about how well managed the port is in the LS50. I've got a real bias against ported speakers in my small (11x12)room but the LS50 works in that room remarkably well and is the first ported design I've had in there that doesn't start to get on my nerves after a few weeks of listening. It's a nice speaker. I rotate it in and out of the system along with the Harbeth P3ESR and would be hard pressed to pick a favorite as each has its own strengths and weaknesses vs. the other.
Best Bookshelf speaker 1300.00 budget
Imaging/clarity are most important. Will be used as 2 channel stereo system with no sub. Don't need alot of bass for my listening..however some is needed. Have listened to Revel M105 1300.00 pr and from reputation Ascend Acoustics Sierra 1 for 850 or so. Willing to listen to recommendations. This is for a small living room that is not closed in...10 by 12.
