[QUOTE="squeak9798, post: 801198, member: 555320"] Audibly there is little difference. The main difference is that, with the sub mounted "normal", the sub is displacing a certain volume of air within the box....so you need to make the box slightly bigger to account for this. You don't have this with inverted subs because the subs basket/magnet assembly is not in the box. Keep in mind, RMS is NOT a power requirement. If you have 4 1000w RMS subwoofers, you [I]DO NOT[/I] [B]need[/B] 4000w RMS to power them. RMS power is typically a thermal power handling figure. So, theoretically they should be able to thermally handle 4000w RMS. But, mechanical power handling is box dependent. Put those 4 subs in a large sealed box, and it is doubtful that they will handle 4000w mechanically (i.e. you could physically damage them). 3000w or 2500w may be all that is needed to make them reach their full excursion. Also keep in mind that it takes a rather large increase in power to notice a little audible increase in output. So, you don't have to give them [I]exactly[/I] their RMS power. If you have a 500w RMS sub, 400w to it would not sound any different than 500w. It's very likely that 350w wouldn't sound much if any different than 500w to the sub. Plus, like I said earlier.....power handling is box dependent. In the right enclosure, 500w RMS may actually be too much power for the sub even though that's what it's RMS rating is. Every company gets bad reviews at some point or another. Nobodies perfect. Should sound pretty much identical. [/QUOTE]
