    I've been E-mailing Scott from Fi Audio back and forth but it usually takes a while for response and i realize hes bussy at the dB Drag World Finals. I desperately need these specifications for my Fi X 12s. LE in Mega Hertz- Z in Ohms- PE in watts- Ive been trying to get this info for weeks now so that i can finally build my box. I would really appreciate it if someone could help. Thanks, Ben

    Hey guys, Finally ordered my Q, 15" w Cooling+Spider... so pumped! but now I have a dilemma I have ported box that is built to the specs of 3ft. cubed @33hz, but wanted to know if I will hear any audible difference by going to a 3.5cube @33hz? Is it worth it for the Q? Goals are just to have the loudest setup given my amp (1500d sundown), sub, and trunk space Just wanna know what, if anything, i would be missing out by keeping the box at 3 cubes thanks

    I am running a fullyloaded bl15 off a planet audio bb2400 making about 1600rms. Electrical- big three, 1/0 throughout, second battery in rear, voltage stays around 14.3, drops to 13.6 for tones. My first enclosure was 5ft^3 tuned 36, 60 sq" port, with bracing, angle boards and routered port edges. Sub faces drivers seat while port fires up behind passenger seat. I hit a 143.8 meca style. Built a new box 3.5 ft^3 tuned 45 with all the bracing, angle boards and routered port edges and dropped to 141.7. I wanted to find out what box changes I may make to increase score, and if I was crazy trying to reach a 150 with a bl?

    Hey guys. Got a question concerning how much power to give a BTL. My previous system was a loaded 12" BL @ 1ohm load, and pushed by a 1500D amplifier with gains at about 7/10 and 4V headunit @ 22/35. I figure it was about 1200RMS? Now, I see all these people with BTL's saying they push them with 3500RMS+. I just don't see how that's going to be possible.. I'm asking because I figured I could get away with running a 2500D amp for a single loaded 12" Fi BTL . Should I really be looking at more powerful amps?

    i just planned to put my 18 btl in a 6th order bandpass (60 hz / 30 hz tuning) and i already got the wood sawed too. ive never tried a bp yet so i thought it would be nice to give it a chance. what do you think? is it better to put the btl in a big ported box or go with the 6 th order. i currently have a 5 cft ported box @ 30 hz but i want to increase efficiency and loudness of the box. amp is a bxi 2610.

It gonna be subs firing up port along bottom out back. Im aiming for S.Q.L, i figure it will be loud regardless I'm not trying to put up huge numbers i want it to be very deep and clear thats all So im thinking Height = 26.5" Width = 47" Depth = 39" All in 3/4"MDF / im doubling the top sheet where the woofers are going. According to the RE Box calculator which i dont know how accurate it is it tells me Internal Displacement = 16.068 CuFt Before Sub (0.24CuFt x 2),minor Bracing( maybe .4CuFt) and After Port Displacement.…

  18. This is a box plan I made, and want some output on this. I was hoping someone could double check "my work" as you would call it, to see if everything seems okay. Image attached along with specs below: box image Specs: For a 15" fi ssd in a 1st gen mazda 6 trunk. .75 MDF Gross box volume 4.05 cu ft. Net volume: I suck at math, no clue. Hoping to be within 3-3.5 cu ft range? 4" aeroport tuned @ 33hz. ***optional setup (I am leaning towards this)*** 4.05 cu ft. gross with 6" aeroport tuned @ 35hz. Dimensions: 15" tall x 35" wide x 30" BD x 4" TD x 29.15" angled front panel length. As I said, honest opinions are GREATLY appreciated, as I want to nail this project. Thanks! -…

    I was plan of buying 4 Fi BL series 15's. I needed to know how much RMS wattage could the speakers really take. I am going with the flatwind voicecoil, with the cooling option, and the daily driver. I already have an amp in mind that puts out 4kw. If the speakers can take a little more I will looking into maybe a 5kw amp. I do plan to use a bass processor in line with the amp. I am open to any suggestions.

    Title says it all. I can build a enclosure with about 11 cu ft (internal volume, displacement of the subs has been removed). I read on a forum a while ago that you get the best SQ if you go with a big vented enclosure. I want to hit the lows but not to loose the highs completely. I listen to almost everything that's called music. That means from Queen to ATB to Bob Marley. My goal is SQ. The car is a Toyota Celica GT, this one: I will be using a Hifonics BXi 2610D amplifier pushing 2600W rms on to two Fi Q 18" subs. The optimal vented enclosure as I have read is from 6-10 cu ft for one, meaning 12-20 cu.ft. for two subs. Or 4-8 cu.ft. for a sealed enclosure, 8-16 cu.f…
