Fi Technical

just wanted to let you know scott that i sent you an email yesterday concerning this so you can check your junk mail folder incase it was sent there. let me know if you got the email. it was for a BTL 18 fully loaded. email is [email protected]

My 12 " Qs sounded bad since i bought them a few weeks ago (used) so today i figured i would build a new ported box for just 1 instead of having both in a sealed box. This is what i found when i took the woofer out. Looks like the motor wants off the basket pretty bad!!!!!

just crusin didnt even make it off my street sub up like half way.. sub cuts out, amps not in protect, no sound whatsoever out of the sub... pull out the DMM.. 2.1 ohms resistance at the wires out the sub (my dual 1 BTL in series) ok.. sub is not blown? set to voltage.. check the outputs on the amp got fluctuation in voltage with music on, unplug the RCAs voltlage stops fluctuating.. so i figure I'm getting signal from the amp, from the headunit, to the sub... where the hell is my problem I'm stumped.. Dual 1 ohm 18" BTL in 6.7 cubes@31hz in series to 2ohms Hifonics XX-Cyclops wired to 2 ohms ~3KW RMS been running it this way for about 2 years maybe longer.. didnt c…

Does anyone know what the F3 for a pair of X 10's sealed in 1cft will be? Will be at 800~900 wrms for the pair. I listen to metal-hard rock, with the occasional techno/hiphop just for show off. Trying to save some space and these woofers call for some tiny sealed numbers so I think this is the way to go.

X series boxes!! 10” X series ported box cut sheet! 1.14 cubic feet @ 32Hz 12” X series ported box cut sheet! 2.3 cubic feet @ 32Hz 15” X series ported box cut sheet! 3.2 cubic feet @ 32Hz

ok i have a major question i just payed for two of the 12" x series subs on the black "Fi"day sale so my question is are they 300w rms like the site says or really 250w rms beacause if they are 250 i will have to change my order to some different subs because i need more wattage than 250 i was hoping the 300w rms it said on the site was right and maybe even underated so i could push 700w rms through the both of them

Could a X10 with the BP power option be put in a larger box than .55cuft sealed? I have a box that is ~.75cuft and another that is ~1.2 cuft. Both sealed. Just curious how/if it would work in one of the larger boxes. With the BP option, what rms can I expect to run in the .55cuft box? And if poss what rms in the larger boxes? Thanks

??? Thanks

Why does the FI Q have 27mm xmax and the BL only 21. Does this increase with options like the BTL? I'm sure the numbers are correct. Any help will be greatly appreciated. Trying to research which subs to use for my application. 418s in a single reflex bandpass. I heard lil johns 1612s ssd's and they were very smooth. I've been leaning towards the BL's myself but cannot for 1 second knock the SSD's. just a little confused on the Q's Xmax being the most in the lineup. Thanks again - Joe Rod

I was just wondering if you guys could make a dual 1 or .7 recone for a 05 XXX?

great news...just ht 150.7 on the termlab with my setup... all i had too do was turn the sub volume on the HU up.... 2 bl 12's crescendo 3k amp.........

I'm wondering if this is a good idea. The box being 12 cubic feet @ 35 hz with 189 square inches of port. That's about 15.7 square inches per cubic foot. I can tune slightly lower, but will sacrifice port area. Is this a good design for daily driving?

I havnt heard back from you yet, did the recone kits get sent out cause i really need them by the weekend, and you told me they would be here in time. If you can send me the tracking info please. Thanks: Les Rutherford

Hey Scott, Les here i been trying to get in touch with you for a while now about the recone kits. Please get back to me ASAP i need them fast

I've got a Q15 with BP Power in 4 cubes @ 32Hz with 58.5 sq. inches of port powered by a Sundown Audio SAE-1000D in my grand marquis, and I want to try a new enclosure. This is a trunk car and the seats do not fold down. What were your favorite enclosure specs for the Q15?
