i have two btl 18 fully loaded daily, im getting two cresendo audio 3kwp's amps, only part i dont know how and where to design the port at i want the port tuned to 32 hz, im doing the subs up firing , my external max dimensions are 45" W x 33" D x 23.5" H. i need help with port design and/or placement as in a port type crx, slot port, ect ect... which one do you guys think will have most output and will coincide with my box dimensions. . p.s. do you guys think the XS power 3100 is a good battery to run with this setup? along with the yellow top under the hood.

Hey I was just wondering, which pair of subwoofers would hit louder on the same power, 2 12" BLs or 2 12" Alpine Type X's. any input would be appreciated, so long as it isn't fanboyish, if that makes sense.

Hello all! I just order a ssd15 over the weekend and was gonna be powering it at 800 RMS. Currently my order is for just the basic 15, no flatwind, no bp power. But now I have the opportunity to get a better amp and I am trying to decide between the Sundown SAE 1200 and the sundown SAZ 1000, I read with the flatwind and bp power you can put a lot more power into it, so i was looking at changing my order to include one or both of the upgrades. Both of those amps are the same price so I wasnt sure which to go with. So the question is! : Which amp with which upgrades would give me the best performance for the sub? Thanks, Ryan

i was going to get a fi bl 12 but now in thinkin about getting the fi blt 12. if i get a blt what would be a good amp for it? and how much louder is a btl than a bl?

I'm kicking around the notion of upgrading my Atlas to IB3s. I wanted to know if the IB3 line was going to get upgraded to the single magnet design like the other sub lines did? If they are going to be updated, is there a time line? I'd like to get the latest and greatest. Thanks.

i was looking at the fi website and both have the same rms so can someone tell me the difference

im buying a new truck 2003 chevy silverado swb 4x4 reg cab i went and measured i can fit 2 12s sealed or 2 10s ported im going with the fi ssd i already have an amp its an audiopipe 1500d the fi's are going to be stock no upgrades.

Ok so I have a few questions about getting two 12" Fi BL's, I want to buy two of them, but want to make sure they will fit in the trunk of a Honda Accord Coupe first. They will be powered by a Cadence ZRS-8 which will do around 18-1900 rms @ 1 ohm. 1. What size of a box will I need for two 12" BL's 2. Will the subs be louder if they have there own chambers/port? 3. What does the box need to be tuned to for them to sound the loudest but still sounding good with music? In case you need to know what type of music I listen to, I listen to a pretty wide variety such as, hip hop, rap, screamo, metal, some techno, and alternative.

I'm looking for strictly output here. I have room for about a 4 cuft box to house 2 12's or 1 15 in a ported enclosure. My question, if I gave the same amount of power to 2 12" SSD's as opposed to one 15" BTL, what would have the greater output? It's roughly the same price for each option, so that's why I'm wondering.

i have another buddy looking to get a 18 inch btl and he wants to build the box before he gets the sub.... seems like a bad idea to me lol dunno why but i would like to know how much sub displacement to account for when building the box for a single 18 btl... he refuses to listin and jst gets all pissy when i tell him to get the sub first then make the box to fit it.... so before he does somthing stupid i was thinking maybe this info could be found here.....

Just wondering so i'll know how much plexi glass to get so you can see the whole subwoofer while it's sitting in the box. So it's obviously 15" wide put how tall is it? Hope someone can help me or Nick over at Fi. Thank you

what is the shipping weight of btl 12 fully loaded ?

Im ordering a subwoofer but first I would like to know the real RMS not peak power i see 3 different size subs with Rms: 2000W * | 2000W * * stands for not legit?

Just got the UPS email last Monday. Shipped/Billed On:24/05/2010 Type:Package Service:STANDARD Weight:43.00 Lbs <-------------WOW! talking about woofer on Steroids! I cant wait... :popcorn:

Hey guys whats up will i have a problem running one btl off that much power?

should i use 8 gauge wire to wire it down to 1 ohm to amplifier or will it be to thick?? im just worried that the wire will not fit when i connect positive from amplifier to other positive double wire in same opening.

All I can Say is WOW. I went from an 12" Alpine 1243d SWS. I love the way the SSD sounds. So clear and deep. Im only running 600 watts right now but hopefully more in the future. I'm gonna recommend Fi subs to everyone. Great job. Customer for life

Is the new Q that much better? I guess what I'm asking is, if I can buy a used fully loaded Q for $185 shipped, Is the new Q that much better to spend $330 shipped? I know I'm comparing used to new, But, what does the new Q do better than the old one? Beside look sexier. And before I get any crap about not searching. I did. I went back three months on all three Fi forums and didn't find a thread comparing the old and new Q.

i'm thinking about either getting 2 fi bl 12's or 15's. i was wondering what would be better for sq and spl if it's hooked up to either a audioque 2200d or a sundown 2000d?

Hey guys Im set on buying the 15" BL the options im looking at purchasing is the Hyper Pole and Flatwind Coil and Daily im looking at getting the Hifonics Brutus Bxi1610D amp which puts out 1200 RMS at 2 ohms and 1600 RMS at 1 ohm. I would rather have it on 1 ohm but can the BL with those options Handle that power Daily with no problems.. I wont be blasting it full too much. If not then i guess i gotta settle with 2 ohms but i heard Hifonics RMS is underrated? I have stock electrical with Alpine Deck and a oversized Capacitor with 4 Gauge wire. Dont know the measurements but i'm going to put it into a ported box thank you !

I'm looking to get 2 BL 12's installed , and was wondering if there were any suggestions on amps for my system. I want a quality amp that'll go great with the system, but dont want to drop top dollar for it. Any suggestions?

12" q or 12" bl ok i was woundering which sub would be louder both in a box with 2.5^3ft tuned to 33hz. with the same amp and be able to tell me why! both subs will be stock no options powered by a rockford fosgate p1000-1bd thanks

ok im going to get a fi bl 12" sub its going to be powered by a rockford fosgate p1000-1bd amp... was seeing if i needed to get any of the options or keep it stock

Are the BL's in stock? I know you build them after order so I guess I should say parts If so, i'll be ordering tomorrow. Thanks

Just got my new 12" SSD's and now I'm looking for an amp to push them. I know it says they will take 800rms a piece but will they take more? And if yes then will they be able to handle 1250rms a piece? I have them wired at 1 ohm together and I use them daily.
