Fi Technical

hello its me again I AM A be buiding my box tomorrow but i dont have a desing yet, ive tryed winisd but i just dont get it and i dont realy trust the reaudio calculator, so if somobody here with good experience building boxes would just make up a desing for me i will pay 5 dollars through paypal sorry but im kinda broke... lolz my dimensions are 39" width 19"height and do whatever deep i just need from 6 to 8 cuft. thanks a lot.

How would i wire this my friend told me to get the dual 1 ohm and he knows what he's talkin about but the amp is rated at 1000 rms @ 2 ohms. Can someone tell me how to wire this

Hey everyone. I am a new member but have been reading a lot of threads here for a while. I recently purchased a 12'' SSD with the copper coil option for my 03 S-10 ext cab. I plan on throwing the recommended RMS or more at it. I am now struggling to figure out what type of enclosure to build for it. I have read good things about sealed and ported for this subwoofer. My goal is to have a good sounding setup that has the potential to be loud if I felt the need. I want to build a ported enclosure but am afraid of port noise seeing the enclosure is in the cab with me. I can build a sealed enclosure also pending peoples thoughts on this. If anyone with knowledge on desig…

I need help with box specs. I have 4 BL 15's going in a 2003 tahoe. I want to face them up( at the roof) and have these measurements; 48 wide, 28 high, 36 deep. Can someone give me a box layout or cut sheet with port measurements to make this a winner. Daily playing tuned low 29-32hz please. Thanks in Advance.

I had an enclosure built and waiting for it to arrive. I am impatient and wondering what you guys think about the demensions. I got a basic 12" Q D1. Sealed enclosure: Width= 14.75" Height= 12" Depth= 15" Which is said to be 1.27 cubic feet "net volume" I am planning on facing the sub upward toward the roof in the back seat of my truck

How much does 1 BL 10 weigh? Also, if running 1,400w to one, can i get away with p chamfer or is cooling required?

I was told I can wire this in series to achieve 2ohms. But when I looked up a diagram for the wiring, it didn't make any sense. can someonen post a link of a good diagram? The amp is rated at 1200 watts @2ohms. rms. I figured this would be a perfect match for the Q. Thanks for the help.

I am kinda worried about something damaging my Q. It is going to be firing upward, toward the roof of my tacoma in the extra cab. But i don't want it to be in the way of the sub (excursion)

If I were to order 3/4 MDF boards from Home Depot. How much should I get? I want to get a LITTLE more then I should get, but not an overload of it. This is for a 20H x 25W x 20D box that will hold a 15" BTL. Thanks, -Curt

Would you guys suggest tuning a BL 15" to 28hz? Has anyone tuned their box for one that low?

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.

Ok, I give up. I need some more direction in building a ported enclosure for my Q10. Right now, it has about .5ft^3 in a sealed enclosure and I really love the way it sounds, I would just like it a little louder (or alot haha.) But anyway, this is in an extended cab S10. I have to admit, its alittle underpowered with my Sundown sae-1000d because it wired at 2ohms. So it gets about 600rms. Any ideas? I would like to use tube for my ports if possible, not really a fan of slot ports, but i'm open to anything. Thanks, Mike B.

I will be building my first custom box for a Fi Q15. I will be putting it in a 1994 Toyota Camry. The cargo space is 14.9 cuft, I will edit my post later knowing the actual dimensions I know there are a lot of experts on this forum that can give me some helpful advice on how to prepare the box and how to correctly brace it. I have used a layout generator online and I was wondering if these dimensions were suitable for it. Net Volume: 3.3 cubic feet Tuning Frequency: 32 Hz Port Width: 4.75 inches Port Area: 78.375 Square Inches Port Length: 55.25 inches External Dimensions: 28 wide x 18 tall x 26.75 deep. Color Count Width Height Top/Bottom 2 28 inches 26.75 inches Red 1 2…

Are you guys able to recone a 10" TC OEM woofer. The surround had ripped completely from the center cone and i just want to have it fixed.

I recently found out my Tinsel Leads were blown and i'm not sure how to fix it... Is this something i could fix on my own? Or will i need to send it in? If so how much will it cost? and where do i send it in too?

I am planning to purchase a BTL 15 when they are available, i would like to know what kinda applications this sub is gonna be adaptable to. I had a DD 9515G, but everytime i talk to them via e-mail or on the phone their customer service is severely lacking lately. So i sold it. I would like to run one of the BTL's in the DD's place daily in a T-line Enclosure, and then in a standard slot ported, or possibly kerf ported enclosure for when i wanna meter it. What kind of options are gonna be available, and what the specifics of them. I went the the website, and the options and just complete overview of the sub is obviously being revised for the new model. Options i reme…

Hi! I

I am building a vented sub box for a 12in BTL thats Fully loaded.. it is going into a 2005 Honda Civic... right now I have the Height as 15inches, the width at 32inches and the depth at 13inches.. it comes out to 2.70 cubes I am tryin to figure out the Port size and length for the box to have it tuned to 32hz if anyone could help me I would greatly appreciate it.

scott, been sending some email this past few days, did'nt get any reply is everything ok? pls. check your email...thank you

hello, If anyone can tell me the port length for a 15inch fully loaded BTL that would be great. they took down the specs for the new woofer i guess, making it unable for me to read it. So if anyone can tell me all the port information for a 15inch btl i would really appreciate it. Thank you

I want to build a sealed box 25X15X17 for a Q15 is that big enough? Should I add any bracing, if so where Thanks Jacob

ok here's what i got...99 mustang rear seat delete wanna do a bl 15 d1 sub up port back in a 4.36cf box@33hz(that's internal)...i was told on here that fi's specs for cf are after speaker displacement...internal dimesions for box are 15x15x33.5...as for the port i got 4x15x25.66....does this sound cool...btw that 4.36cf is before port/bracing deplacement..as i stated earlier i was told that the fi specs for speaker displacement are already included....if someone can confirm that this is all good i would greatly appreciate it

What's the smallest you think i could go with a BL 18. I'd probably wire down to 2 ohms and get about 1100 out of my amp if i went sealed. I've got some extra wood from the real box, and i thought that i could make a box to take up only one seat for when i want to take an extra person, but still have some sound. I don't see a ported working because i couldnt make the port big enough i dont think, maybe i'm wrong. Anybody ever sealed a BL 18? I doubt too many have, but what would it sound like? (also, when i say small, max dimensions that id like to use are: 23H*17-18D*22W, which is 4.4 cu ft after wood displacement.) PS: regular box is 6 cu ft tuned to 34 hz, so please d…

hey all. i want as big of a sub as possible but the only problem is that i will have only 16.5" of height in my trunk. thats means if i get a bl 15 my sub will be very close to touching the wood (height wise) in my subwoofer encloser. is it bad if the sub doesnt have a lot of clearance height wise in its encloser or does that only apply sideways in corelation to the port. just wondering if i should be ok soundwise with a tight box or will i sacrifise sound quality by doing this and just stick to getting a bl12. thx -phil

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.
