Best speakers for classic rock

Jbl l-65, l-200, l-300. If you can find them in good condition and reasonable price. 
Forget l-100. Overrated and shrill 

Sealed box acoustic suspension to get that midbass punch.  This ported stuff is for tea parties.  😊

I had EPI 120s when I was a kid. Those things can rock! I am not an expert on the range available at that price level today, but for $2500 you can either get a pair of new in box ELAC UniFi UF-5 Towers, which I did own at one time. Excellent speakers for the money. Take the change and invest it back into your system. Another idea is to buy a pair of Magnepan .7i or 1.7i speakers. Depending on which you get you may have enough left over for a subwoofer. The Magnepans have an unbeatable soundstage for the money. I have the 1.7i pair and love them. Taking delivery of a pair of Magico A3 at the end of the month (I hope) and the battle will begin!!

McIntosh 252 Integrated Amp and a pair of B&W 804 D3's.  Listening to them now and they sound great no matter what I am playing.  The 252 is a tube amp.

I highly recommend to go to places like Magnolia inside the Best Buy and listen for yourself. Burn your favorite songs (I did 30-60 secs clips for 12 songs) and listen for yourself songs that you like to listen to. The more expensive speakers recommended by many others were not for me after listening songs I would like to listened to in the listening room. It's very subjective. Only you can tell.
