If you want to know how necessary these are, along with spikes and high priced cables, head on over to the DIY speakers and subs section. That's where the guys who really
know how speakers work hang, and where you'll find some truly jaw dropping systems. You won't find any mention there of iso pads, spikes, or cables, because those guys know better than to waste money on things that don't work.
All recommendations of what is best for any given room is completely subjective. Most of us don't have any idea what a "perfect" listening position in a "perfect" room is like. Me, personally, my room is less than ideal, but I make due with what I have. My Auralex Grammas seem to help response in MY room. Could this be placebo? Of course. It is all a matter of what any person is willing to spend their hard earned money on. I would personally never advocate high priced cables, but am rather giving my opinion on something I've had experience with.
That being said, again to any Outlaw owners I would suggest (and recommend) a product from Auralex.
Again, my room is less than ideal, and I, personally, feel like I achieve a better response from my subs on Grammas. IMHO, if you're spending that much money on a sub, what's an extra $40 to produce a bit more of an expectation?
Keep in mind this is all coming from someone who originally had the gain on their sub at 5+, and did not understand anyone on this forum who had theirs set at less than 2. Mine are both now set at less than 2.
Dedicated HT rooms VS functional HT "areas" are a very different being.
Would I love a dedicated HT room? Of course, who wouldn't? Realistically, we all make due with what we have, whether it be WAF, or functionality.
I, personally would love to be able to afford a room with bass traps, diffusers, and such but in a living space, that does not, have a chance at functionality. Any who are considering, and I'm sure there are plenty DIY's to making products similar to those that Auralex produces, but myself, I'd rather just fork the money for a Gramma.
