Ya, Ive got foam padding under mine for hard floors, keeps them from walking and gravel from sticking/digging into the line-x. It doubles as trailer packing material between cabs. No corners on my, just naked.
I'm impressed they pass the Evan TRX test, but I think Im gonna keep my RMX2450s wired up to mine, they seem a very good match.
never had to clip them.
Update: I had a long drive home in the snow and thought about Evan's outing with the Growlers.
I don't believe you can simply throw speakers together and call it a system and expect it to perform to it's full potential.
My thoughts:
1 As a system both the tops and subs need to be "dialed in". You can simply crank the tops and expect the subs to keep up.
2 If the tops are very efficient compared to the subs, they most probably dont need as much gain as the subs. In other words you cant simply swap in another set of subs while leaving your tops gain the same and expect it to sound right.
2a. My experience shows that large linoleum floored halls EAT up bass.
3 Another sip of beer.. (that was a tough ride home thru the woods...) ah better, OK, if premise #1 and #2 are correct, then you need to start at the lowest common denominator, which is the max SPL you can get for the subs with the power you have. That means you need to back off the tops gain to match the subs.
4 No matter how large the room, your system is what it is, with the subs being the limiting factor, in this instance. Its not their fault, you simply need 2 more of them - remember - those are only 500W 12" drivers in those cabinets, 4 cabinets for large hall would not be unreasonable, especially with those screaming tops.
Usually sub power and cabinet "density" is more than the mains, from my experience.
Glad Im not in a ditch,
Mike
