do u have parts available to recone a treo ssx15? dvc 1ohm thanx, Peter

looking at an 18" Q in a 4cuft sealed box....would a us md-1d be too much for power, or should i look into the bl line?

Ok, well Im trying all I can do to get some cf out of the box that im making to go under my back seat of my truck... I have figured out I can get about .74 cf out of my box but i might be able to get another .1-.2 cf out of it.... If it stays at the .74 cf, what would that do to the sound? I can use polly fill in it also, would that help? And if i can manage to get it up to .8-.9 before displacement, how much better would that be because it will be a decent ammount of work to get those extra few tenths of a cf...

Can someone give me the screw hole diameter of the 15" Fi BL? I saw the outer diameter was 15.625" but did not see a screw hole diameter. I am working with limited height and don't want the screws to be lined up on one of the boxes wall. Hoping I can save around a 0.5" inch on the height just having the outer surround overlay on the outer 3/4" edge of the box. Thank you for any help! I would measure it myself but I am ordering the woofer in the next few days and want to start the build now.

Im in the process of designing a box for one Fi Q 15 and I have a couple quick questions. If went over the 12-16 square inches of vent area per cubic foot of volume would this affect the sound Quality? I was just curious because I have seen a few enclosures that definatly go over this and sound amazing. I am going for more sound quality vs. SPL but want to get the most out of my subs. Also I am planning on tuning the box to 32 hz, that was the recomended optimal freq. for the 12" Q but does this also apply to the 15" Q? Any help would be really appreciated. Thanks in advance, Zach

Hey guys, my enclosure is nearly finished. The specs are.... It's 3.97 cubes before displacement, so I am guessing around 3.5 after due to the sub displacement and the bracing. The box is tuned around 33hz. I've tryed it in my friends vehicle and it pounds pretty hard. Not 100% happy yet. I'm thinking that's just because it's not broken in yet. I heard it in a Ford Expedtion, but the sub will be going in a 96 Cutlass Supreme. Hopefully it will get much louder. I'm powering it with a JL 1000/1. But what I'm wanting to know is are those good specs for the box? That's about the biggest box I could fit in the trunk. Help would be appreciated!

Hello everyone It has been awhile since ive las longed on to this accound but now im back. I got a Fi Bl 15" about 3 yrs ago and i would have to say it was the best/ loudest/best built sub ive ever come across. I had my box made by a guy out in Canada. His company name was Pound That Sound. Since i havent been on this website in awhile ive noticed that he no longs makes enclousres.... Ive been looking around for someone to help me with my next built since ive gotten a new car. Im sticking with the BL and i going to have the same set up likelast time, 1 BL 15" w/ hyper pole option. Now my question to anyone who wants to answer is... is there anybody you would recommend for…

Looking at building sub box for BL 18 also considering possibly running 2 BL 18s and wondering minimum cu ft for both in the one box ported box-- is L=3' W=2' H= 1.5' i did the calculation right im sure but just wanna double check thatll be enough cu ft hey Thanks

when u enter the box design posted on the forums for the ssd into the re box calculator i get a tune of 30 hz ??? is this right cuz i need to change the dimensions a bit for it to work for me i making a rear center console for a 10 ssd. and also i can only seem to get 17" of port area not the 27 i assume i need will this be a problum ??? and also i will not have a L port just a straight slot. any suggestions or help would be appreciated thx

Am planning on using the Hifonics BXi2008 on 2 15 Fi Q's, would BP be necessary?

I noticed that on the first view of the cut sheet for the bl 15 that it says the width of the box is 33 3/4" but on the other two views it is 34" , is that some kind of mix up or am I missing something?

I'm going to order four 10 " Q's to be mounted sealed each connected to it's own Alpine PDX 1.1000 , ( all 4 were benched at 1200 RMS ) , my question is BP power or no BP power , i have seen posts where they were said to perform wonderfully under 1000 watts , and many more that stated they could take more , so i'm confused as to if i should BP them or nt please answer , thank you

so im looking to build a new box for the blow through in my truck. trying to think of some new designs to make it interesting. is there any benefit to having the subs angle towards eachother? i was thinking having them facing eachother down the center with plexi on each end so you can see the inside. thoughts?

Hello Guys. I guess I could introduce my self before i start asking crazy questions..My name is David, I am a Firefighter, I live in Mississippi...I ordered one of the Fi 15 BL with the cooling option, Flatwind option and Universal setup..Daily driver...I am going to be powering with a Xt4000d Us Amps Amp. I have a Honda Civic and I will be using a ported box in the trunk..I have designed a box and was wondering if you guys that see these designs everyday think this one will do me justice...I used some measurements I took of my trunk and how I would like the box to sit...I will 45 all the corners in the box and build it as close to this as possible...Please look and tel…

Well, here's the deal. I've been running my 15" Q in a sealed box for the last month or so and I am wanting to build a ported box for it sometime soon and need help getting a design together. I have no problem building stuff, I'm just no good at getting something together that will be right for my application (right ft^3, right port size, cut sizes, etc.). Below is a pic. of the largest outside dimensions I can possibly go with. The 4" rise is to clear the tranny hump (it's going in an ext. cab silverado.) I'm wanting something tuned to ~33 hz or so. If anyone can get together a design for me, that would be great. Just send me a PM or reply on here and we can go into fu…

How are you guys/gals fitting such long ports that are necessary for the Q12 into not very large boxes (1.8-2.5 cuf). I am designing a ported box for my single Q12. (2.2ish cuf @ 32ish hz) I am looking at a 6" port that is around 30 inches long. Is everyone using slot ports with multiple bends? I am not looking to compete or steal any secret designs. I am just looking for suggestions of what other people are doing to port the Q12. Thanks.

Never mounted an amplifier right next to a woofer before, so it i tried it. Currently I have two 15" Fi Q's mounted invertedly behind the back seat of my car. There was just enough room to mount the p450.4 in between the magnets of the Q's, which positioned the amp perfectly at the reach through in the back seat. Doesn't seem to affect any perfomance aspect of the amplifier, so I guess all is good there, maybe i got lucky, or maybe i'm just sketchin. Next item of business though, What about mounting batteries too close to woofers? Does it matter? Talking kinetiks here too, not some cheap lead acid. I wouldn't see why this would be a problem, but I learn new things al…

Hey guys, After putting my 15" BL together in a 3.5cuft box, which sounds awesome, now I just have to fix my amp problems. Anyways, I have to build a box for a friend for her 15" Q. I suggested sealed since she wants to do more stuff in the trunk and I didn't want to take up the whole trunk like my box! We both have Scion tC. I was thinking a box for the 15" Q sealed with the exterior dimension of 12" high x 32" wide x 16" deep, with 3/4" wood. That will give an interior volume of 2.69cuft w/o sub displacement, so with the sub it is 2.5cuft. The sub will be powered by a Kicker sx1250.1 amp, that amp supposedly gives out 1250 watts at 1 ohm. So with that given se…

I have two MA XL15s that I want to recone. how do I go about doing that. Must I ship the subs to FI? here is a picture of the sub in case people don't remember them

I have 2 rockford P2 15" d on a TMA amplifier 500.1 in a 4.5 Cu. Ft. Box ported. I'm in the process to get 2 Bl 12" d2 and I need the know if the HIFONICS BRUTUS BXi2608D will be a good option (cheap one) in a 5.0Cu. Ft. This will go in the trunk of a Toyota Yaris 5 door. My budget is pretty tight, that the main reason why I decided the BXi2608D. Here are the pics of my trunk Visit My Website

I just ordered a 15'" bl. I order a dual 1 cause I wanted to run 1ohm. I forgot that with 1 ohm you can only got to 2 or .5. If I get another bl dual 1 could I wire it in a (series/parallel) and get 1 ohm. Thanks all

what are the mounting depths and displacements of btl's when you get the extra magnet? i tried the search but nothing comes up. also, it would be nice to have it all in one place for future reference. *edit*..... i just read that you guys are releasing a new btl. in any case what are the mounting depths of both new and old?

Would you recommend multiple ports are a large single port for 2 Q 18 D1s with cooling and the extra spider on an AudioQue AQ2200d, in 20 cubes after displacement tuned to 28 Hz? Car is a 2004 Tahoe with the max box dimension limits being about 27 H x 49.5 W x 36.5 D. I had a few designs floating around, I think one was with 4 8.5" round ports, one with two slots along the bottom of the box, and one was a rectangle in the center measuring 15.5 H x 19 W, so 294 in^2s area and was 22.35 in. long. The dimension limits leave about 7-9 inches between the box and the rear, 7 at the top and 9 at the bottom. I was thinking the large port might not have enough port speed, but …

I'm pretty sure this isn't possible but, I was wondering if the Q series was universal. I have a Q10 D1 coils paired with a Sundown sae-1000D wired at 2ohms. I know that some of the subs you can change with a recone. Otherwise anyone know some magical way to get a 1ohm load on my amp haha.

I am in need of two 15" recones and baskets with screws for my RE SX's at the moment, I will need two more at a later date. I need dual 1's with some slightly bigger tinsel leads, not the spl ones from the btls, if that is posible. I need the total price for all of that shipped to 47987. Thanks; Andrew
