Best overall Speakers for $2,500.00 or less, New?

The only speakers that I can think of that would satisfy your requirements (without the need of a subwoofer) will require you to troll the used market, but are well within your price range. Thiel CS3.6. I recently picked up a pair that look brand new for well under that. They are indeed very much a full-range speaker (29Hz-20kHz, +/- 1.5 db), and I think do a pretty darn good job of hitting all of your requirements. And Thiel will, in general, continue to honor warranty repairs beyond the 10 year period and for subsequent owners, so long as it was not user abuse.

Snell E.5 are $1,400.00 have a rear firing tweeter to add spaciousness. It's a floorstander with 2) 6 1/2" woofers and a 1" tweeter. 43" tall and 46 lbs each. Side by side, much better than Monitor Audio silver 9's.
Polk Lsi 15's are about $1,500 and more bass with side firing woofers but I think the Snell's are better.

magnepan 1.6 and a subwoofer. It's going to be though to get something as uncolored as a maggies for your price range. And definitely NOT with a floorstander. I would demo the Paradigms and the Magnepans to see which brand you might prefer.

Here is one vote for the Vonschweikert VR-2. Absolutely amazing full range speaker that lists for $2500 but can be had for less. Best speaker I have heard in this price range. Listen if you can, before you buy anything. Good Luck,

For magical midrange and staging, brand new BBC LS3/5A mini-monitors from Stirling Broadcast with "reference" outboard crossover and "reference" cabinets will set you back 2300+ duckaleros. Stands available from Stirling will bring total to 2500. Can't beat w/ stick.
