Love Hard Rock, and I've gone through a number of speakers.
Some suggestions.
Ohm Walsh 5000's or 4900's. The 5000's essentially have a 4 band EQ on the back. But, you actually want to take advantage of room reflections. Really like mine, and plenty of bass slam, no subwoofers needed. HUGE soundstage, excellent with live music. I sold off more expensive speakers to make this move. It's a different older design, but has been refined. Not much makes sense about them other than the sound when properly set-up. They are not perfect, but they do an awful lot right.
In the Legacy - I would find a way to score some of the Focus SE's used. I do like the Legacy line-up, no substitute for displacement. I think the Focus SE is worth stretching for, or finding used. LOTS of used ones out there pop up. Good Rock and Roll Speaker. I have come close on the Focus SE a few times. It's a big and heavy beast. I like it a fair amount better than the Signature SE, which given the budget I would look used.
Used Vandersteens - Nice big open live sound.
A21 has plenty of juice to push either around. Neither is overly bright, which unfortunately a lot of older Hard Rock recordings are bright, shitty recordings. So, the smoother speakers I find help if you listen louder like me
others...
JBL 4367 - Fun Rock Speaker. Some of the M2 technology (the M2 if you want to go a different direction, sell off your parasound and use a pro-amp and DSP is an awesome rock speaker)
JBL 3900/4700 - great fun speakers, excellent drum sound. May not dive as deep as you want. I owned the 3900's for a while. Felt they needed a sub.
JTR - small builder out of the midwest, like his stuff.
Salk Song 3 encore. Maybe the "truest" sounding speaker. Plays deep, accurate. Not quite as much thump, but a great speaker and craftsmanship blows just about everyone else away.
ATC - awesome midrange and snap. Biggest issue is you have to spend an awful lot to get into their range that you won't want a sub.
