Does any one know what the QTS becomes on the option of raising the QTS? I plan on getting a pair for sealed, but want to know what the QTS are. Also Plan to run a 1500 rms to each, should i get a extra spider? just dont want to lose the low end making it to stiff in a sealed box. input would be greatly appreciated.

hey all my brother is about to buy a 15 Bl(d2, cooling) and hopeing to run it off a b120d(brutus) in an enclosure witch is about 3.4-3.7 cubes...idk about how much port tho.. i do have a couple of questions tho.. is the Bl ok to run at 1200, i know the rms is at 1k and i think it can take the extra 200 watts but i want to make sure that it can, can it? is 3.4-3.7 cube well enough to run the bl at, and if so how much port would i be looking at? ok with ported boxes is it better to have the sub more towards the begining of the port or further away from the port begining? thanks, steveyblack

friend wants to buy a BL 12 and place it in his car. he wants it even with teh rear seats so its a bit tall of a box. does this look proper for such a sub? http://imgur.com/a/IUDaJ

Hi, i recently bought a recone kit for my Btl. It was a 12" and I am upgrading to an 18". I cut the surround and spider to remove the cone. Now, i see the screws holding the basket to the motor. Simple, right? Well i cant get the screws to break from the motor. They were soldered on to the metal. I broke the solder with a screwdriver, and now i'm left with six screws that WILL NOT budge. I really put some power behind one screwdriver and the screw started to strip on the top. Any ideas?

what kind of enclosure am i looking for? i have a 1995 lumina, and now im seeing what kind of box i should go for. ( i have a very large trunk. ) i think my MTX JH55 is a 4 cube box. and i still have room for a little more, could someone post the exact and best enclosure for the FI BL 15? and is there any very good box builder for xp or vista? also could i get exact specs for the 15bl with cooling, daily, universal, and a red dustcap. ALSO would a hifonics 1200ixd amp wire at 1 ohm be ok to power this amazing sub?

Putting a brand spankin new 15" Q dual 2ohm in a 97 honda accord. This is for daily music kinda stuff, no comps, I just want it to be clean and wang on the lows. I was wondering if anyone has had experience with these trunks and knows what can fit in em. I am thinking that ported would sound best but am open to all suggestions. Also, if ported should I go with slot port, aero, other? If my measurements are correct, Max we're looking at 17 tall x 32 wide x 22 deep. Will a ported 3.0 ft^3 sound as nice as 4.0 ft^3? Any help would be great

Basically I'm stuck between two designs. The first one is 4.3cf with a 6" flared aeroport tuned to 35Hz. The second enclosure is 3.5cf tuned to 32Hz using a slot port, with 54" of square port. The power is 1000 watts rms at 1 ohm.

I am running (2) of the 12SSD's in a ported box at right about 4 cu. ft. net and its tuned to about 32 hz. power is rated Zapco 1000W if I can get another cu. ft. What can i expect in the characteristic of the box? More efficent? more boomy? I do not want to make it sloppy, it's already ported which is a trade off for me to begin with. Or I might consider the max sized sealed box. How would you compair that to my existing ported box? thanks

I was wondering to expand my knowledge and thought others here would benefit from my ever growing thirst for knowledge... i thought i would ask to help myself avoid these problems and also help educate those that aren't aware of these issues and how to avoid and/or discover the following problems.. Anyways.... as it pertains to sub woofers (particularly Fi built ones since i own some) 1. What is mechanical failure? 2. What are signs of mechanical failure (sight, sound, smell)? 3. What are the most common reasons for a sub to experience mechanical failure ? 4. What is thermal issues/problems in regards to sub woofers 5. What are signs of Thermal problems/issues (sight, so…

I bought a fi q 12 last year. I bought it with the intention to put it in a ported box. I have a genesis, the box is wayy to big for my trunk. I kept the sub in my garage until now. im planning on making the smallest sealed box possible for the sub, which i beleive is .8 . I selected a whole bunch of options, cant remember which ones though. Are there any options on the fi website that says the sub would have to be exclusivly for ported boxes? I know they have the high qts option, for sealed boxes. Im not too good with all these subwoofer terms, lol. I just want to know if i can put the sub in a sealed box without worrying im going to mess the sub up.

Whats up everyone. I'm new to this site and im looking for some help with my box build. I just got a Fi Bl 15 dual 1 fully loaded and i am wondering what dimensions i should use to get the most slap outta this sub. I went to RE Audio and used there box calculator and came up with: W: 38" H: 18" D: 17.5"... Port width: 4" port Length 12.75. Second port length: 16"....with 4.2 cu ft. in total for volume. Box is Tuned to: 31.63 hz Does that sound alright? Also im buying a Hifonics BXi 2010D to power the BL so id be giving it 2000 watts. Is that to much? Let me know what you guys think. Thanks

Forum, I have a SUV and my setup is 2 BL 12's in a shared chamber ported enclosure tuned at 33hz. I was wondering would the subs sound better facing forward or to the rear of my SUV tailgate? The subs and port are on the same baffle. Right now i have them facing forward and it sounds really good but just wondering am i losing out on that chest pounding bass if they are facing the rear?

What are some good amps that can put out 1600RMS at 1 OHM. Please post the price of the amps if you can. Dont want to spend to much.

I am buying 4 15's and I wanted to know which was the better choice. I understand that they both have the same RMS wattage I am going for more spl and lower bass. I wanted to know which sub would produce more bass in the lower octave. I have no problem as far as space I just wanted to know which produces more output.

Hey. I am doing a 5.5 ported box in a hatch of my 1995 camaro, off of a hifonics 20006D, What Sub(s) would you recommend? I want the sub to hit the lows and be pretty loud. I was thinking a 18" BL. Tuned to 36-37. Or maybe 2 15" SSDs? Not sure if these subs will be suffocating in the box that is 5.5 without displacements.

need help guys ..i cant decide what to get ...here is a little info,i have a trans am and the box i going to get that fits the rear well it has 1.92 cubic feet per side ...i was going to go with 2 15" or 2 12" ....the amp i am going to use is a sundown 1500d the 2-12" i was looking at are FI SSD or FI Q and the 2-15"are fi ssd or fi q...its a sealed box ....for that amount of air space (1.92cu ft per side) what would give me the best bass sound...thanks

i've been reading about the whole tinsel slap thing and it's kind of scaring me... i got a single 15 hybrid transmission line built by stratusrt01 a few months ago, he okay'd to me that sub a btl would work fine in there, are their any plans in the future for any upgrades to the tinsel leads? i was thinking of getting a fully loaded 15, the car is 2002 caddy deville, the box is stout as fudge, resin on the seams, i'ma 250 pound dude and i jump on it all the time, and it's rock solid. i dont do music for the numbers, i just a daily beater, just trying to get some feedback from the people with experiance. Thanks in advance fellas.

I have a 12'' fi Q and when i got my box built the guys put a separate wire on each voice coil. Its a dual 2 ohm sub. What is the final ohm i am getting once i connect it to my amp?

Hi guys, need help on box measurements, such as specs for depth, height, length, port size for my ssd 12" in a sedan for trunk firing, thanks in advance

Well here it goes, I am planning on running 2 18" Q series Fi's in my daily driver(2000 GMC Safari). I need box design ideas for this aplication, I want it to be more aimed at sq then db. I am running a Alpine pdx 1000.1 to each 18 at 4ohms at 1000watts rms. The room I have available for the build in the back measures 50 inches wide by 34 inches deep by 21 inches tall. plan on useing 3/4 mdf for box. Pritty much need to know everything what hrz to tune it at, How many ports, what size ports, slot ported or round. Let me know what you think any ideas would be a great help. Also when are the Q's going to be available to order.

Ok if I build a box that has a port that 'folds' would that be just as good as a regualr port?

Hello, I'm thinking about getting 1 18" bl sub pretty soon, so I'm designing the enclosure now to make sure it fits. I have a 2000 Crown Victoria Police Interceptor, so the trunk is pretty big. I want to do a sub up, port back enclosure, but I'm open to anything. I'd like to get it around 7ft^3. Here are a couple pics from a crown vic's trunk. I wrote in my trunk dimensions on one of them. They are (as accurate as I could get ) 26"D x 41"W x 20" H (13" clearance under the spare tire, 20" for the whole trunk) Heres a video with the kind of enclosure I would like to build Would this be possible in my trunk? Also, what dimensions should I be looking at for my port? I'm a…

Hey so i want to tune my box to 32 hz. but i am confused on how this whole box design works. The previous systems that i have had i just bought boxes, but this time i want to build my own. I drive a jeep cherokee so I have plenty of room in the back end for a big box. 1 12" Fi Btl sub. Dual 2 ohm, fully loaded. Brand new. (I have not purchased it yet, but when I do, this is what I am going to buy) Wheel well to wheel well is about 42 inches. Back seat to back door is about 25 inches due to my seat coming out at an angle. (I lose about 8 inches) The floor of the back end to the roof is about 38 inches. The floor to the top of my backseat is about 18.5 inches. Here are some…
