Fi Technical

hello i was just wondering if i could get an update on my sub...i sent it in last month and got a reply that it was in....and then replied back to fr...and haven't heard since thanks....josh

Have any of you used an SSD 10 for home subwoofer use and does it work well. I have a high quality 2 channel stereo system at home and use a subwoofer to fill in the bottom end. My present sub has an RE Audio SR10 dual 2 ohm driver and a 500 watt rms amplifier. I am wondering if I would get an improvement by using a Fi SSD 10 dual 2 ohm driver. It would be used in a sealed enclosure to get best quality bass and be the high QTS version. Any opinions would be welcome. I am a bit confused about cabinet size as I keep seeing different optimum box sizes quoted, ideally I would like to know what the HQTS actually is so that I can model it in WIN ISD. I assume all other T&S …

I am looking for more SQ so i figured i would go sealed. But since i have a larger space, should i go ported? I want tight-punchy bass, I like feelin some of the high bass. My current box is huge and ported, so i think this would be the right change (sealed). Thanks

I'm putting a BL 18" just with just the P chamfer in my van ill be running 1200 rms too it. the room i got is 49"w 41"L 41"H. i really need too see like a print out. too look at while i'm making it. i want it too hit low. and i know nothing about tunning so if you could explain that too that would be nice. alot of people were talking about haveing it 7 cubic feet and tuned too 33hz would that be a good setup for the box? thank you.

Anyone know the total weight of the 12 SSD? Or even just the magnet weight? thanks

I was wondering if this box would be big enough for two 15" fi btls. The box is 38 length X 25 width X 23 height. After displacemnt of everything its around 7.5 cubes at 31hz. The port is 6 wide and 25.5 long. It would be for daily use and each ran a sundown 3000d. thanks for the help

Got my bl today, went to bolt it into the box and noticed that the holes in the gasket don't go all the way through. I can see the holes on the bottom then the lip that comes off of the surround goes over the whole and blocks it. Do i drill through it?

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.

i want to recone my 18 to a 10, any body know who i can contact for one or a price?

ok so the set up would be 3 12" BTL's (fully loaded) and 3 sundown 3000d's..I'm lookin for some basic dimensions for an encloser and some places online that can do a quality build.Also,any suggestions on port Fq. would be appreciated..It's gonna be a daily driver in a '96 impala trunk so i have room to play with.Thanks!

Hey I own a 03 Tiburon GT and am planing on putting in 2 12" BLTs with 2 SAZ-3000ds. I want to compete in SPL but also want to be able to listen to music (not as important). What type of box should i get ported or seal and should I get a wall or will it just be a waste of wood. I don't want to do a wall unless it will boost me db. Thanks for the help, I don't have a clue what to do.

Hey guys girls just wondering before i tear the system outta my tahoe and redo it which box will be better....the current box is for 2 18" fully loaded BTLS...ea sub has 6cuft after displacement and tuned to 32hrtz...but would it be louder deeper etc if the box was 1 chamber tuned with both subs..kinda like steve meades...just wondering.....also running 300amp ho alt (soon to be 2) big 3 all 0 gauge 5 batteries 2 US AMP MD-3D 1 on ea sub....let me know if im forgetting anything thanks

ok someone told me before that if they were standard 3" coils then they could be reconed. well i got bored and ripped on of my blown T1's apart. outside of the coil is 3.204"-3.244" and the inside of the coil is 3.020"-3.051". bent a lil bit, maybe from removing it. how much would it cost to recone? how much power would it be able to handle? would i just be better off buying ssd's? thanks. p.s.- any more dimensions needed ill see what i can do, its kinda hard to get into the basket with a 6" dial caliper . but ill see what i can do if ya need me to. the gap in the motor is approx. .145"

It is 6.5 cufeet internally tuned to 30hz with 111 inches of port area. What is your guys thoughts on it? to much/to little port area? not enough room inside the box? just post what you think on it.

ok so i hooked up my new fi ssd and my kicker 750.1 amp. ok so the problem. when i turn the volume down all the way on my kenwood kvt911 headunit. i still can hear a little bass. then when i turn it up its not loud at allll. i turned the bass up on headunit and still the same thing im soo confused someone please help

I currently have a Q12 in a 1.35 sealed enclosure powered by a Cadence TXA-1000d. It sounds really good right now, but I cant help but think this sub can handle a couple hundo more watts on a constant basis. Am I right that it can handle more or is it just wishful thinkin?

I have 4 15" kicker's in my car right now running off 2 hifonics 2006's. i am thinking about putting either 4 18's into a truck or 2 18's of the trunk of my car. i want to flex and have a lot of bass. i already sound loud i my car but i want more. do you think i am jumping out there to far with purchasing 4 fi btl 18's? and if so what sloutions do any of you have for me to get flex and more bass? I will probably using the same amps or buying the slightly higher rated brutus. Oh just fyi the car is a lincoln towncar

I recently purchased a 12" Q series sub. I am installing it in a ported enclosure and I am curious to the size and tuning. After purchasing the sub I found a deal too good to pass up on an amp that is a little underpowered for the Q. It is a kicker zx750.1. It puts out between 800-900 watts rms. I see on the pinned topic at the top the recommended ported enclosure is 1.8-2.5@ 28-33hz. With 12-16 square inches of port volume. My question is should I change the box size or port area since the speaker will not be driven at full rms power? I want to get as much out of the speaker as I can with the power I have available. I thought I would ask on here instead of calling seeing…

Hello I'm new to this forum as i have just purchased a used Q18 " sub and i want to get the best from the sub for my suburban, i listen to rock and rap and i want to make a ported sub enclosure for it, sub up port back. my question first is could anyone help me design a enclosure with the best tuning for all around use? i love the lows but i would like it to not only go low but have a punchy bass aswell. if anyone could help a Fi newb with this it would be much apreciated. thank's i'll give specs of the area i have to work with, 47w 24d 22h ,99 suburban using a fosgate t5002 pushing aproximatly 800 watts, my goals are just a daily driver setup with good sound quality. an…

I'm looking for the exact dimensions of the MT gap or the exact coil dimensions to see what other coils will work with it. If Scott or Nick see this i'd appreciate some info. If anyone has the MT coil sitting around and has access to a dial caliper or something to measure precisely I would really appreciate the help. Or if anyone knows the gap dimensions off the top of their head lol...

alrighty fellas i've decided to go with a 18'' btl-n2 and my truck is a 2000 gmc sierra ext cab long bed. i know the rear seat is gonna be gone i am planning on pushing the 18 with a soundstream dtr3400 and a ported box tuned around 32 hz so if anyone can reccomend enclosure specs i beleive my dimensions with the back seat out are 54'' long , 34'' tall, 24'' deep. if any body can help me out i greatly appreaciate it

I haven't built it yet I am just exploring options and found a design I kind of like. 8 cu. ft. tuned to 34 hz with 101.25 square inches of port. The port opening will be 4.5 " wide and 21.5" long. The box dimensions are 33x24x27.5 overall. It will be a crx style box , and will go inside of the cab of a 2000 chevy silverado. I plan on pointing the port towards the driver's side and have the sub behind the passengers seat. Do these specs seem alright to everyone? Would a different direction with the ports yield better results? Does that tuning seem alright or should I go lower/ higher? I want SPL but also enjoy the low notes that a highly tuned box sometimes lack. If any…

If u get the full cooling option on the btls does that include the pole piece venting also as well as the side venting. Or is it just the side venting and the pole piece is covered?

Other than thiele small params and the small pics, it's hard to know all of the differences.... the Q has a smaller pole vent? larger magnets? The single 2 ohm IB3 is a 2 layer coil, the Q is 4 layer. The Q's Fs isn't much higher than the IB3's and the motor doesn't seem tooo much bigger.... IF I had the extra $$$ at the time I would have gotten a Q because it would have been much better for my application, I could have gotten the dual 1 ohm coils and ran my Lanzar OPTI2000D at .5 ohm and everything would have been GREAT. But I only had enough for the IB3, and so I let the lower Fs and higher Xmax ease my mind about doing what i had to do. If I could go back in time, I k…

hi i need to rebuild a couple tc9 based eclipse subs and i was told this was a good place to look. how can i go about purchasing a recone kit or two? they are 12" subs dual 4 ohm coils. im looking for something that can hopefully handle more power than the eclipse coils thanks in advance chris
