Hi, I've been looking at the discussions about frontfiring vs. downfiring subwoofers, and the article at AdireAudio.com about sag of drivers measured as a percentage of Xmax and the possibility of mounting one that way. Even if my drivers look very cool I'd still like to mount them in a downfiring configuration, just so that curious hands or pets won't damage them. Still, from a logical point of view, I find the following situations. 1) Gravity. I'd think a subwoofer would need to use a lot more energy in pulling a subwoofer's cone up than from side to side. 2) Impact. I'd assume that the soundwave that emanates from a front-firing subwoofer "hits" you harder than a sonic wave that hits the floor first and then sends the vibrations on all directions. 3) Accuracy. A front firing sub, IMHO, should be more accurate, since the soundwave travels to you directly. I'd think some kind of distortion is added if the sub fires downward first. Still, *all* of Adire's designs are downfiring... and all Sonotubes are downfiring... so something must be *right* about it. If I decide to mount my subs in a downfiring position (I checked their specs against Adire's recommendation, and they have around 3% sag vs. Xmax, so I'm ok), what should I do to be assured of accurate sound? Mount maybe a panel of MDF 4" underneath the driver? Would that be overkill? Should I only space the driver from the floor by 4"? Thanks for your help!
