Fella's, I am running 2 BL 12's in a ported 4.23 cubic ft enclosure tuned at 33hz. Is this enclosure large enough for the BL subs? The enclosure is 1" thick all sides, braced inside 1" thick and has a 2" front baffle so i know its strong enough.

placed an order this weekend for a 12" BL that will be running off of a hifonics 1606. i've drawn out plans for a box thats 2.33@33hz w/33 sq. in. of port area (haha). will the hifonics be enough to push the sub? i can go bigger on the box to let it use the power a bit more efficiently, but whats your guys' opinions on this? anyone w/experience as to exactly how much power the hifonics is capable of putting out?

i don't really want to take up the whole back window up i did some measurements and i can do a box that's 52.5W x 24.5H x 16.5 deep. externally that's 12.28 Cuft 10.18 cuft internal. After displacements of the 2 18's and 3 6 inch aeroports that are 12 inches long each it gives it an internal volume of 9.083. will this be enough for 2 18's for bass racing the 140-149.9 class? i am ordering 4 Sundown 1500's when jacob gets the new ones in. i plan on strapping at 1.4 so each amp will see .7. i also will have 6 optima group 31 yellow top batteries.

Ok, after everything i think i have finally decide to get 2 bl 15's. I just need what amp you guys would suggest using on them and i only have about 600 to spend on the amp. Thanks.

Hey, I've been looking at Fi car audio for a while to help fix my BMW's horrible lack of bass. I was originally looking at the 12" Q but after reading around I decided that the BL would better suit my needs, I now am at this problem I know my trunk can fit the optimum box dimensions for the 10" and 12" but I dont really want to sacrifice all that space but then I want it to also to be hitting pretty hard. Also whats a good amp recommendation for the best price/performance

Hi im gettting a 12" q and i was wondering if this could be done? I just dont want to worry about tinsel slap and i kind of like the look better thanks

I am getting one 10" Fi SSD sub-woofer very soon and I am having a bit of trouble on what to do for the enclosure. I drive a small, 1998 Ford Pickup, single cab. I am convinced, and determined, that it is possible to put a sub in any vehicle, but there really is very limited space back there to put anything. Does anyone have any experience or suggestions? I am looking for the best sound I can get, but I understand if it won't be optimal. Getting the materials and building it will be no problem, just need to know how to tackle this.

This is my original plan and am wanting to make sure this is my best option for Loud and clean bass. I was used to running 1 Audioque 15" ported at 29hz in 7.5cu ft box off of 1400w, it was ungodly! Current setup - 1 Audioque 15" Sealed in 2.2 cu ft off of 1400w. It is a little less loud in the low frequency area due to a lot lower group delay as well but like how it sounds as well. Anyways, my current project is to have 3 12" Qs off of 3 optidrive 2000ds. Each q would be wired to 0.35ohms all in a common chamber sealed box roughly 2-2.4cu ft stuffed with polyfill (emailed fi about this to see what they say bout the polyfill). Now, these amps are rated at doind 1,600w at…

I have 2 FI BL 12's in a 4.23 cubic ft custom enclosure. The enclosure is tuned at 33hz. Is it possible to play below tuning? Also i cant seem to find anyone to set my gains properly so i will i know if i am clipping?

I just finished building my box last night.... Double baffle,Fiberglass,etc... My box after bracing and before the Port was 8.25cuft(internal)I have 119 sqin of port tuned to 30hz. After the displacement of the port I now have 5.85cuft. Now is my box 8cuft tuned to 30hz OR is it 5.85cuft tuned to 30hz??? And would that be too small for an 18?? thanks

So i am about about to add another BL to the trunk the both will be dual 2's, daily, P Chamfer, and univeral features.. Im looking at sundown audio for my amp. Which model should i go with? any reccomendations, sundown or any other brands?

getting two 12inch BTL's fully loaded, dual 2 whats the optimal cubic feet this box should consist of and optimal port size

not trying to be a pain but are the specs going to be posted anytime soon.i know the specs say they are a sealed sub but everyone knows how well they perform ported now they have been out for a while.

I'm in need of some help on a box build. I'm planning on getting 1(one) fully loaded FI BL 12" dual 2ohm. I would like to know what size and type of port to use, I would like a slot port (not sure what its called) tuned at the recommended 32 hz. If some one could get me some ideas on the size of port to use and that sort of stuff(i have no clue how to make a good port). I have a 3d cad package (SolidWorks 2007) to were I can design it my self I just have no clue what size and type of port to use, or how to use it. The set up is going in a Chevy Cavalier 2 door (rear seat does fold down, not sure if its relivent) and the amp I'm using is a Power Acoustik BAMF 2000/D (r…

Hey i blew my speaker and i been sending FI emails and myspacing them, but i haven't heard anything from them. Anyone know how to go about sending my speaker to them, or how to get in touch with them, like a phone number, or something.

How do these dimensions look for my Fi Q12 d1 Box outside diameter after using 3/4" MDF: Box: 33.5 x 14.5 x 12 Port: 1.5 x 13 x 16.5 This should give me 2.53 ft3 (before taking away sub/port displacement) and be tuned to ~32 Hz. I have been using website like the12volt.com and a couple others. I tried the RE enclosure app, but I think it is a little off. Not too sure. I appreciate any help! If this box looks off, what would be better? Thanks.

I have one SSD10 D2 with copper coils in a sealed box with about 600 watts rms coming from a Phoenix Gold Ti600.2 I know going ported will give me more output but i'd really like to stay with the sealed box I have because it fits perfect in the truck. So, i've been looking into getting a 1000 watt amp like a Sundown 1000 or Alpine PDX 1000. Would this upgrade be worth it or should I stick with what I have?

Finally got my hands back on some straight street jam material. AKA: Qs and a BTL UFO I've seen some UFO BTLs have a spacer in between basket and the motor. Is this just an adapter for basket patterns or is it a beneficial option to the sub? Excited for my new Fi experience and so is the wife =]

I am wanting to know if these numbers are sufficient for a vented enclosure for for a 12" BL. I will have it hooked up to a MTX TA81001 A 1 ohm in the trunk of my 06 Honda Civic. Any suggestions would be greatly appreciated. Width: 36" Height: 18" Depth: 15" Port Height: 16.5" Port Width: 2.5" Port Length 1: 11.75" Port Length 2: 6" Total Port Length: 22.25" Port Area: 41.25" Internal Port Volume: 917.8125" Port Volume Displacement: 930.5625" Box Volume: 3.909 cubic ft Tuned Frequency: 32 Hz

I have a 07 Tahoe and 2 BL dual 1 ohm 18s on a hifonics BXi 2010. I was looking to add 2 more 18 BLs in a 18cu. ft. ported box tuned to 32Hz. I also wanted to upgrade my amps to 2 RF T2500-BDs strapped at 2ohms. My question is will this be too much power for the subs? They are fully loaded for daily use. Please help. Thanx.

Two Rockford 1500.1bdcp and four fi bl 15s dual 1ohm, with these amps can they pound the bl pretty hard. If I build a custom box for my jeep srt8 will it be loud as hell breath taking, head ache bass. And can anybody help me with box dimensions , cubic ft, airspace in chambers, port size and wat to tune to.

Hey finally making some progress and decided to get the Q instead of BTL which will be here on the 3rd. Just wondering whats a good amp to power it at around 1000w-1500w at a 2ohm load. Also what are some good .5ohm stable amps out there and about how many watts would I be looking at running it at .5 instead of 2ohm Plan on going with around a 3cu ported box tuned at around 32hz to go in a 03 honda civic coupe. (If this information helps)

Just was wondering, how much rms do you guys think a new FIBL 15 daily with no upgrades could take?

You guys must be busy...I sent a few emails and all I get is a message saying something about email delays...o well I guess I will have to wait a couple more weeks to knwo when my subs will be shipped back to me.

I need some one to send me a template for a 15" Btl So i can see if i can fit them before i buy them. Also so i can get the holes cut for once they come.
