If any of you had a choice between 18" subs, what would you do?
(qty:1) Ficaraudio SSD18
(qty:2) Mach5 MJ18
The sub(s) would be going behind the screen wall in a dedicated theater room measuring approx. 13'Wx25'Dx8'H. Size of enclosure will not matter but have ruled out IB (for now anyways). The sub(s) will be fed 500w. The sub will be used mostly for movies and I'd like to get as low and loud as possible.
IF you are comparing 2 to 1... then I would say right about even....
2 machs moving in unison would move slightly less air than 1 F1...
to calculate swept volume SDx Xmax x 2= SV...
for one F1....50820Cd
for 2 Machs.....49392Cd..
You rather get 2 15 inch tempests...which will move 50480cd....which is about dead even with 1 F1.
Here's a REALLY dumb question....
Who makes the tempest? Whould you be able to get me a website so that I can take a look at them also? Tax time is here and I just might go for 2 subs. I was looking at 18"'s but if 15"'s will kick my chest in just the same, then they are worth the look.
I don't know about those...but looking at the specs..they lack dual voice coils, less xmax .... but pretty close... I haven't seen too many of those in actual usage...so I can't tell for sure.
You are a stones throw away from the Canadian distrubutor of the Tempest..who is in Abbotsford... do you have a connection in getting stuff form Part Express without paying shipping and customs?Last time I ordered something from PE... it cost me more than double in shipping and customs... with Fedex...

Hey Kanaris, couldn't you get PE to ship USPS??? I always avoid UPS and FedEx like the PLAGUE man!! LOL!
Yeah, I'll be in Vancouver this weekend, we might just pick up 2 Tempests Classics while we're there!
The sub will be located behind the screen wall so size will not matter. Also, with your choice in sub, what amp and how much power would you use. Remember, I want the sub(s) to dig down really deep and loud.
FYI, I had build a sub with a 12" titanic and 500 BASH amp but it did not move me.
These were modified for IB use. Check with him to see what would work best in a ported or sealed box for Home Theater given your specific situation.
According to him, the stock Q18's have too stiff a suspension for normal home use... they were designed for ulitimate car use with extremely high power and SPL capabilities.
The reason for "over doing" the subs is because due to the large size, the enclosure will be located beuind the screen wall but the screen wall would have to built around the sub enclosure which means that I need to get this right first before proceeding with the construction of the screen wall.
Based on your information, I can try (1) Q18 first to see how that goes.
Do you have Scott's email address or his contact information so that I can go over my project with him?
