Very small very sensitive floor stander 1000?

I've got a Pro-Ject amp box powering the Arros just fine for rear surround (or is it?). I'm really a two channel guy who dabbles in surround. Fronts are Wilson Benesch Curves powered by Kharma MP-150s. I have a used Zamp already purchased, which I was going to swap in as the rear surround amp for the Arros, and then use the Pro-Ject with the new speakers as a bedroom system.

I second the Monitor Audio RS6 idea. Really like those speakers, even driven by modest AV receiver.

How about Focal Chorus 714V? They are very efficient, a little more than 35" tall and sound very good.

I would also have suggested the Triangle Altea EX, but they are over 40 inches tall.

I have had the Preludes, Arros and Micro Walsh Talls in my listening room at one time or another. The Preludes are handsome and, used, a real bargain. And they're skinny... but if they're too tall for your location, so be it.

The Arros and and the Micro Walsh Talls are exactly the same height, but present a slightly different footprint. The Arros are 5" wide and 7" deep. The Micro Walsh Talls are 6 x 6 inches, so they look a little larger from the front.

I'd suggest giving John Strohbeen at Ohm a call. Tell him about your location and amp situation. He's a good guy and will be honest with you. The Ohms have a 120-day in home audition period, so you can't go too far wrong with them.
