Fi Technical

Thinking about switching up from my 15 BTL to 2 Qs 15... Would I see any huge difference in loudness... I mean the BTL is god awful loud but I'm always wondering. Trying to figure how to fit everything back there the two dekas, 2 1500ds and a 100.4. Thinkin 7 cubes @ 30 hz.

ok so the ssds are rated at 1000w ... so if you have them fully loaded ... what would that do for the rms power handling?

Why is the recommended tuning frequency for the Q 18 so low?

So since my order still hasn't shipped after 10 business days, I might as well make sure my box dimensions are correct. Going with a 3.5 cube ft box tuned ~32 Hz Port is 17" by 3" and 37 inches long Anyone see anything wrong with this? Thanks.

Umm I'm having a bit of a problem. I need someone to go into bass box pro or whatever you like and design me a box. The external dimensions are 27Hx40Wx25D. I'd like it ported. Please don't tell me to get different subs or a different car, I just can't make that happen.

I had an enclosure built and waiting for it to arrive. I am impatient and wondering what you guys think about the demensions. I got a basic 12" Q D1. Sealed enclosure: Width= 14.75" Height= 12" Depth= 15" Which is said to be 1.27 cubic feet "net volume" I am planning on facing the sub upward toward the roof in the back seat of my truck

Due to tight angles I need to know the OD on the Motor for a 12" BL. Thanks

Other than thiele small params and the small pics, it's hard to know all of the differences.... the Q has a smaller pole vent? larger magnets? The single 2 ohm IB3 is a 2 layer coil, the Q is 4 layer. The Q's Fs isn't much higher than the IB3's and the motor doesn't seem tooo much bigger.... IF I had the extra $$$ at the time I would have gotten a Q because it would have been much better for my application, I could have gotten the dual 1 ohm coils and ran my Lanzar OPTI2000D at .5 ohm and everything would have been GREAT. But I only had enough for the IB3, and so I let the lower Fs and higher Xmax ease my mind about doing what i had to do. If I could go back in time, I k…

building a normal box but using two layers of 3/4 mdf all around, which way would be the strongest? i know the first would be the easiest with less cutting, but would number 2 be so much stronger that i should definetly go with that method? Number 1 Number 2 any opinions are appreciated!

Looking to build new system. Planing on using a Memphis 2500 watt amp to each sub. This system will be mostly for SPL but also some daily listening. Will be using 10" or 12" subs. Just wondering which Fi sub would work best. Will start with 2 subs but move to 3 at a later time and maybe a Memphis Mojo 4kw to each also.

i have purchased two 12 inch FI Bls both are dual 1 ohm, and have cooling and hyperpoles. i am purchasing a box from sonicelectronix.com that fit the specifications of the subs. my question for you is wich amplifier would you recomend? i plan on wiring both of the subs for a 1 ohm load so i was gonna go with a SOUNDSTREAM PCX 2000d any suggestions ?

I need to recone my BL and was wanting to know if I can recone it to BTL using the double stacked magnet kit.

Hows this sound to you guys. (2)15 Bls Box: 17x39x22 = 6.54cubes (after displacement) Will (2)4in flared ports be enough port area or not enough? suggestions please

would one of this be good or two for a pair of 18Q's...?any other suggestions on an amp is welcomed. http://www.woofersetc.com/index.cfm?fuseac...Product_ID=1818

Ok so how do i wire my speaker wires from my box terminal to my amp just - - and ++ this is for 1 ohm

Hello, I was wondering if someone would be kind enough to assist me with my first enclosure build. I created an enclosure in Torres that seems to meet my needs, but I am not quite sure if there is enough port area for these subwoofers. Being a long time lurker, I know the people here are quite knowledgeable, so I figured I would throw it out there to see if it will work, or if it needs to be changed up. Here is the screenshot for what I have worked up so far in Torres: Does that seem good enough for port area? This is going in the trunk of a 2004 Toyota Corolla. The dimensions for height and width are the max that I can get away with for front firing subs. If …

I have a custom box already built that i have a 15 in at 3.5 cubic feet. I was wondering how a 12 inch btl would respond to 2k watts in that overly large box? P.S. its tuned to 32 hz

Hey everyone i have an 05 civic coupe and i am wanting to put a 4 cubic foot box in the trunk. Does anyone know if this is possible and what dimensions i should use. I am going ported with a btl 15 n2. any enclosure help or ideas is really helpful. i am building this myself so nothing too crazy.

ok, I'm about to attempt to build my first enclosure for Fi Q 12. 1.9ft ^3 tuned 30hz. Where can I get demensions and what items do I need. Such as brands of glue, type of screws, etc. If I Take mesurements to Home Depo, Will they cut the pieces for me? Is it difficult to make a Enclosure, I read that its pretty easy.

right now i have 1 12" ssd fully powered in a ported box. it is 16X22X14. it sounds good and i listen to almost everything from rap to techno. I was wondering if it would be better to switch to a sealed box? i mean one advantage would be less used space. and which direction should i face the box also...

i was wonderin if i could use two of the same amps 1000rms to each [email protected]

Ineed a box for 1 18'' needs to be sealed.I can build one,but dont have the resources nor will my park let me.Stupid country club noise regulations.Shops only build 10s & 12s around here.Can someone help me please?

hey guys im really tight on space..the sub will go into a 2007 cadillac cts and id like to retain some trunk space..i know fi suggests 2.8-4 cuft for a 15..but whats the smallest i can go without suffering any loss in perfomance quality wise and output?

Any chance I could get approximate T/S Specs for my re-coned subwoofers? The hybrids consist of Memphis 15-MOJO15Q1 (15" Quad 1 Ohm Voice Coils) mated to Fi D2 soft-parts with older style tinsel leads. I purchased these already assembled from a friend but he didn't have any specs on them at all. Any help would be greatly appreciated. Thanks, Charlie Buffalo

Is it ok to feed a single BTL 12" with 3000wrms daily? any issues you think I may encounter? thanks!
