    I have an Older 12" Q thats blown. I''ve finally decided to get it reconed but I want to build a ported box for it too. I see the the diagrams and cut sheets for the new Q, but i'm not sure if that will work for older model Q. It's also unfortunate that the cut sheets for that one are a tad too large for my trunk. I have a maximum of 30W 15H 18D, but depth can vary a bit. i was hoping on building the box during the time it takes to get my Q reconed. That should give me enough time to learn how to design a ported box. I have no idea on how to calculate port length and all that jazz. Thanks.

    I got chris at fishercustoms.com to design me box for 2 BL 18's. Its little over 18 cubes before port and sub and around 15 after, tuned to 33hz. Port is 10.5" wide. Figured i would post up design, hopefully i will have it built next couple weeks. We been workin 7 days a week, so as soon as i get a break, will get started on it.

    i recently ordered a fi q 10 and it came in today i hooked it up to my RF p6002 wired 4 ohms and when ever i turn the volume up i hear a awful rattling noise it sounds like it is coming from under the dust cap. i read through the forum and found another person that had the same problem and i think it said his dust cap broke the glue loose or something. if this is the problem how do i fix it? and what do i need to do to fix it? again this is a brand new sub and has never been used before. does fi even test the subs before sending them out?

    Is this too big of a "enclosure and port" for a daily. For 2 fully loaded BTL15 with a T4k ......11.1ft3 (net) with 160sq" of shared port tuned to 30hz....after sub and port displacement subtracted I got a total of 8.6ft3 which would be 4.3ft3 and 80sq" of port per sub. Is that too big?

    I'm looking at building a custom box for my 2 fully loaded fi btl 15s and need some help with the dimensioning. Im looking at have a 9.5 net cubic foot box tuned to 32-34hz with a solid wall brace in the middle separating the two subs. For power im looking at either 2 rf t2500-1bds, 2 sundown audio saz 3000ds, or a autotek mean machine 4000.1. Does this seem like a good setup. Im looking at putting it into a chevy silverado ext. cab of course with all of the electrical upgrades also. Thanks for any help

    about to drop in a pair of d2 bl 15's loaded for daily to replace my d1 q's (to go a little easier on my american bass vfl 200.1, thing smoked on me before and cost over 300 to fix) in 8.2 cubes @ 32 hz. was pushing the q's to their limits, about 1300 watts each, and raising the load to 1.4 ohms (3kw at 1 ohm) i'll probably be giving the bl's about the same power, maybe a tad more. can i expect the bl's to be louder across the board? will they still pick up the lows as well as the q's did or will i need more power to get that low end extension?

    Hey guys, first post! Haha. Well, I recently just received my 15" BTL in the mail. I was looking and it and noticed that there were no screw holes for mounting the sub to your box. So how do you mount it? Another question I had was, is there a special way that I should be breakin in the sub? I didn't know if there was a good way to do it. Thanks guys and appreciate all the feedback.

    I have two 15" SSDs with copper coils, going to be running them off of a Kicker ZX1500.1. I don't have a lot of room to work with after I reinstall the back seats of my truck and all, and I was wondering if anyone has had experience running them in a sealed enclosure? What's the smallest I can afford to run?

    ok guys, currently now I have an 18" BL fully loaded for daily. Its being powered by a JBL BP1200.1 at 1200 watts. Its in a 5 cu ft box tuned to 30Hz firing upward. The reason it is firing upward is because I cannot fit an 18" into my trunk rear facing. With a 15" though...I would be able to fit it rear firing into my trunk. So my question is...what sort of difference would i see? obviously i'd see a drop in ouput i'd imagine...but at the saem time, would it be noticable? Right now my BL is fully loaded for daily driving (daily option, flat wind, cooling). So at 1200 watts, even though its 200 over RMS, it isn't really pushing the sub to that much of its capability im gu…

    Hey guys, as the topic says I have a problem with a SSD 12... the spider feels very weak in a spot like there is a crack under the top one. So my question is will it be fine to run like that? (i don't know how long its been that way but it worked fine till the day I took it out) or do I need a recone so it doesn't get any worse? Thanks

  20. I plan on building the enclosure per Fi's specs of 1.5 ft @33hz. The dimensions I have come up with is 14.5" x 14.5" x 18" using3/4" MDF this gives me 1.4937ft after subtracting the woofer and material displacement. I can add to the 14.5" sections of the enclosure if need be to account for port displacement. I'm not familiar with how to calculate port displacement though so I'll need some help on that as well. I planned on mounting the sub on the 14.5" X 18" side and would also prefer to have the port on that side as well. I just want to make sure that I get this right. I'm looking for maximum SQ but still want to have good output. It will be powered by 550w/rms in a PT …

  24. Started by appleyard,

    As titled says. my max dimension is W33 H17 D26 which I calculate would be 6.52cu^3 after speaker displacement. I have 6.25 round ports and I know its kinna small for the 15Q but thats what I'm planning to use. When I use winisd (i know) with 6.5 cu^3 and 2 round 6.25" port tuned to 30hz I got a 23.57" long. I know my calculation is off because I have not deduct port displacement but hope someone can give input. I know the box is kinna small for the 2 15 but thats the only space I can spare. Most online port calculator wouldn't allow me to calculate 2 ports. Also the sub will be powered by 2 SAZ1500d. Thanks
