Efficient floorstndrs. to reach above furniture


I'm getting nowhere except frustrated trying to fill large space with sound from Silverline 17.5 monitors. Subs didn't work. I'm now soliciting suggestions for efficient floorstanders with drivers located near top of cabinet to surmount obstructing furniture. Space is: 17 X 30 w/ 10 foot ceilings and adjoining 2 - storey entry. Power: Creek Creek 5350 se., which I may have to upgrade. My total budget for speakers and more powerful amp is
$ 4000.00 (used). Thanks!

Coincident Partial Eclipse or Total Eclipse if you can fine a pair for 4 grand. Both sound great, are very efficient, and I don't see a need to buy a new amp. Good Luck.
Stuart,

Well a little over I agree - listed used prices comes to $4500.

JBL Performance Series PS1400 PT800 is around $2500 used.

An older Bryston 4B ST is around $1200 used.

A Bryston Bp 25 sells for around $800 used.

I figured you could haggle - I found 54 preamps listed at less than $300 - so you could go that route. Sorry if this was no help to you.
Shadorne, I should've clarified that ideally, I'd prefer to keep my Creek and just swap out speakers. Thanks to all who suggested speakers-- I will start to research recommendations The Zu's are very appealing, due to their return policy, but will look into others as well.
Agree 100% with Coincident Total Eclipse. $4K on Audiogon. And you won't have to upgrade amp - very efficient and tall. If you have to, you can stand them on 6" Timbernation maple blocks - I did this.
