12" RE MX vs 15" FI Q off ~1500w

Which would get louder and/or sound better?

The Q will have the cone area advantage and most likely will have the ability to get louder, bp option included. Not sure about SQ though. I have yet to hear an MX.

 
have fun with those coils //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif 3 ppl in the last month have had them come unwound on them.. possibly a user error..

Let's hope so (shoulda said something early!//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif) I already sent the payment. It's a waiting game now.

 
hey, tell me how it sounds (re mx) bc i was thinking about a 15" Fi Q with cooling option, but seeing that many people voted a 12" re mx MORE than a 15" Fi Q, im having my doubts now.

anyone want to explain why a 12" re mx would be a better choice than a 15" fi q?

good luck with your re mx, and thanks to anyone who helps me with my questions.

 
Well, stuff wouldn't be here until the middle of next week. So earlier i can have anything install is next weekend. But i'll be building the box this weekend.

But no luck finding help with enclosure. RE recommend 1.0ft^3 sealed and 2.0ft^3 ported. Don, who i am buying the sub from said he had it in 1.7ft sealed and it sound very nice.

So i'll be building both a 1.7ft sealed and a 2.5ft ported @ 33 hz and see which i like. What's the effect of increasing the box volume without changing the frequency?

I would say RMS ratings and efficiency. Also in ported boxes sensitivity rises making a sub reach mechanical limits easier but, if you know what your doing either sub will work of that power. In my opinion I will chose the Mx for that power in a port.

 
making the box larger will help with lower notes, and make the box more efficient making the woofer need less power to move a certain amount. Also, i THINK higher freqencies roll off much sooner with a larger box:)

I would of defiantly voted for the MX also. JUst cuz I love the look, and they sound mmmm mm good:yumyum:

 
I've attached my box plan with all dimension and layout. Can someone please double check my #?

Also, the NET volume was calculated without considering the 2 flares, i can't imagine they'll make a difference.

Thanks! I would hate for port noise to ruin my experience with a beauty!
