It just isn't appropriate for classic rock. Keep in mind it's rare where I can tune a system to the room - often I can't even soundcheck with the mains up (or even at all) :facepalm: .

Also my entire system fits in my Scion xA hatchback - the clientele I service can't afford to be paying me to own a truck or to even haul the trailer usually. My largest subs are Rog 186 18" folded horns that can keep folks back 15+ feet at full boogie, ~ 140db@1m :o . http://www.speakerplans.com/index.php?id=186horn

Different worlds you and I :) .

Fair enough. But don't poo-poo my observations until you've had a chance to experience a full blown rig. I suspect you'll be pleasantly surprised. Even A list classic rock bands are using these rigs to their fullest potential on a daily basis.

RoadRanger:
I've been to too many big "classic rock" concerts where they were mixed like them annoying "boom boom" cars that drive by shaking your windows. Sorry, that just ain't what older rock sounded like. OTOH I don't mind modern music mixed that way if that's what it is supposed to sound like. Also the venues I'm in generally frown upon you vibrating their bottles off the shelves LOL. YMMV.

This will be the last post I'll make on the subject. I'll submit that the reason "classic rock" sounded the way it did was not due to choice but rather limitations of the technology of the day. Both PA and vinyl records couldn't go that low. Records cut with frequencies down really low could cause the stylus to skate and skip on turntables. The Beatles had to really fight with EMI to get the high pass filter lowered when they went to master and still couldn't get everything the wanted. PAs of the day couldn't go down that low either. Many of the classic rock bands that tour now wished they could have had that extension and headroom that's available now. So though you may not like it as a matter of preference or because it's not the way you're used to hearing those bands, it doesn't mean that's the way the band wanted it to be. I've mixed a ton of bands over the years and still do. In many cases, the classic rock type bands like and want the extension. Some don't because they too wanted it to sound like days of old. It's all good either way.

My personal preference at shows of most relatively modern genres is to be able to actually feel the music, not just hear it. It puts me more in the moment when I get enveloped in the lows so long as it's not masking the tops excessively. To each their own.

RoadRanger:
Most important frequencies for "feel" is the chest wall resonance at 50-100 Hz :

I used to do something similar. I had a pair of JBL JRX-125 mains (which for what I was doing sounded great on their own), and for larger rooms with raised stages, or outdoors, I added a pair of Avatar 212 bass cabs, each about 1/3 in from the sides of the stage, tucked along the front of the stage to use the floor and stage knee wall as a great big folded bass "horn." People loved it, and it sounded great. I was mixing almost all kinds of music, but mostly classic and alt rock. No mud, just thump.

I think the JBLs would go down to about 35Hz on their own, and that's about where the Avatars bottomed out, too. The JBLs were by no means flat that low, and the Avatars really helped to even out the range without really pushing amps too hard.

My current rig is a bit more modest -- a pair of 15+horn cabinets on sticks (Peavey PVX15) and a Mackie 18" powered sub. It rocks well enough, though the mains can sound a little boxy in some rooms if I'm not careful with the main EQ. The next audio project is to build a pair of 15" psuedo subs. I've designed the L-slot-ported boxes with a resonant frequency of about 30Hz, and the drivers I'll be using start their rolloff at about 40Hz. In theory, they should be pretty solid in the 40-100Hz range, and I'm expecting to cross over right around 100Hz or so.

I cart my PA gear around in a Hyundai Elantra Touring (i30), along with my keyboard rig. It's a tight squeeze, but I get it there! :)
