Powering Legacy Audio Speaker System


I have 15-20 year old Legacy Audio speakers that were passed down to me.  I'm going to hook them up as a 5.1 system with the following configuration:. All speakers are 4 ohm, and I've listed the sensitivity next to the model.

Front towers: Classic series- 92db at 2.83 V/1m
Center: Silverscreen 2 - 98db
Rear bookshelf: Studio series- 90.5db
Subwoofer: Powered Impact 

I'm looking for a receiver that can adequately drive this system.  I don't have the budget to do separates even if that is the best way to go.

Any recommendations would be greatly appreciated

I would stay away from a receiver.  Are there any multi channel integrated amps you could look at?  Maybe a used Anthem? 
Those speakers are fairly efficient, but they're going to work best with a lot of power.  A receiver could work and it would be OK for home theater and casual music listening.  You say you don't have the budget for separates.  What is your budget?
Check out accessories4less.  They have a number of receivers in your price range.  I don't have any specific recommendations as all of my gear is comprised of separates.  I'd look at some of the Yamaha offerings.
If you run your hdmi directly into your tv and optical to your reciever I would reccomend one of the older powerhouses like the Denon 5803. It's gonna sound better than any of the new light weight recievers anywhere near its used cost. Weighs 60lbs and is 170 watts a channel. Was over 4k new. 
Should be able to get a good one for under 400 if you look around. I lucked out and found a near perfect one in a Pawn shop for I believe $130. I also have a newer Denon 3808ci which was a $1600 receiver. The 5803 sounds much better.
