Best speakers for classic rock

Ohm walsh, klipsch, jbl. If I was was just naming brands that you could find something new or used in your budget.

GE Triton 3+.  With the powered woofers and 92 dB efficiency, they will rock the house. 

B&W 802 . Old school 

I listen to predominantly classic rock - Led Zeppelin, Hendrix, Pink Floyd, Black Sabbath, etc. I also listen to jazz. 

Last year I got a pair of Klipsch RP-600M bookshelf speakers paired with a Cronus Magnum II tube amp, and it’s a great sounding combo for the rock and the jazz. I listen to mostly vinyl with this setup, haven’t picked up a DAC to venture into digital audio besides my Chrome Cast Audio. 

This is well below your budget but thought I’d chime in. Good luck! 

Klipschorns. They have a huge sound, even when driven by a 2 watt Miniwatt valve amp.

Ditto for most of the Zu range.

Enjoy the journey!
