Disagree with Curro101; I think the speaker needs a firm basis so it can shift the air and get a good bass note. Although the carpet is quite firm, and I have used it as separation for my "infinite" baffle cabinet, I do wonder if the support is enough for the speaker mount. My puny 6" are mounted on 1/2" MDF platform.
Agree with PMB, that good separation (along with good support) is needed to get the kick of the bass from the speaker. It's OK for the tweeters and mid range, they do not need to shift air in the same way a sub does.
Looking at the installation on the R171, in the door there is a big sub (8", I think) that is mounted reversed (magnet out).
In an upgrade thread, these were replaced with better speakers, but mounted the same way, and only mod from traditional was to wire the sub out of phase (so the air movement was in phase).
I seem to remember someone mentioning that the same is done on the R170, so the clearance behind the hole that the magnet would go into is not important.
So I'm looking at my rear speaker installation, and wondering.
Should I get the 5"x7" and mount them inverted? This would then use the bulkhead as separation, and also as strong a mount as can be obtained. Only down side is that the cone creates a pressure spot, and this would be wasted into the bulkhead zone.
But then many sub speakers are downward firing, and seem to use the port for the best impact.
Wonder where the port of the chamber behind the bulkhead is?
And how will I mount the speaker grille for the rear speakers? Perhaps the existing speaker mount frame will provide that fixture!
