Fi Technical

I have 1 15 BTL Fully loaded, i was playing it today and it started smoking then went out. I have it on a Orion Hcca 5000, the gain was not up it was below half way, i wasn't playing it for a long time, i don't know what could be the problem. I have heard that Orion amps are hard to tune, i dont kno what the HPF ,and the LPF is suppose to be set to could someone help me.

ive got a plan for my two 12" BL's. it comes out to be 5.5 cubes..is this too big? i can easly shrink it down or make it bigger if needed. thanks.

Just Got my car finally! OMG! YES finally.... ffs Vauxhall (Opel) Corsa Sxi Twinport 3 Dr it is... now i have an Fi Q 15" which im going to go sealed and will be making a new enclosure in the workshop soon, thats sorted, going to get my self a sundown 1000 amp.. now i was just wondering about wiring products, http://www.knukonceptz.co.uk/productDetail...?prodID=KLM-AK0 http://www.knukonceptz.co.uk/productDetail...?prodID=KAR2-6M http://www.knukonceptz.co.uk/productDetail...rodID=KAR124BLS http://www.knukonceptz.co.uk/productDetail.cfm?prodID=ANL200 and some form of terminal cup for box i just want to know if this will/should cover everything to get my sub up and pumping …

Obviously, you can already tell I am major noob at all this, but learning. I am getting the 4 15" BL's when I save up enough to do everything. What I need to know is what Ohm do I need to pick for the BL's. I have yet to get a amp. I was hoping to run 2 amps, maybe the Kicker 2500.1, but not sure. Any and all info on what Ohm setting and amp I should get would make my day better. Thanks.

If one does decide to get this option does this by any means help increase the subs BL and if so do you guys have a estimated number...

I have been having trouble trying to understand on how to make a box design, so I was just going to see if anyone here could help me. I know that when some one asks this question they tend to leave out important information when needing help so I'm going to give you all the info I can, and please tell me if I am missing anything.

i would like to know what is causing my sub to get to the point where i smell voice coil.. the sub is a 08 15" bl flatwound coil p chamfer in a 3.4 cubic ft box tuned to about 42 hurtz. Could the box be to small, port not proper size, lenght or could i be pushing it to hard? I am running jbl gto 1400 at 2ohms thank for any and all input.oh yea sub is d1

Waiting till thursday to order teh new 12" Q but I want to get started on the box... I've got room for a 29.5x19x8.75 deep box... (this is going in the back of a 350z) This puts it at about 2.05 sq ft after the driver displacement. I was going to go sealed, but have changed to ported... I need to figure out the length of the ROUND port to use... I saw a post on the 350z forum where a guy used two 3" ports at about 32Hz "needed 34" total of 3" port to be tuned @32Hz" Can someone confirm, using your awesome math skills, that 34 inches total of 3" port is correct? I'll need to split the ports into two ports... I'm aiming for this look... FI Q12 in the Z... - MY350Z.COM For…

I ordered a 12in fi bl with cooling and flatwind to run from a hifonics brutus brz1700.1. It will be putting out 1700rms at 1 ohm and the sub is dvc 2 ohm. I was planning on a box with the dimensions of 30x30x15 with a 2.75 in port. I was going to tune it to 34 hz so how long should the port be? Or should I get an aero port instead? I want the loudest possible setup with what i have.

I have a Fi Q 15 with BP power in about a 5 cuft box. 3.5 for the sub and the rest is displacements for sub and port. I have the box tuned to 31hz. I read the recommendations for the sub off of this forum and it says about 12-16 square inches of port area per cubic foot of volume. So that would translate from 42in-56in squared of port cross section and i have about 48 inches squared (its 13.75in W x 3.5in H x 36in L) and not very much air is moving through the port and it is not very loud. Maybe it needs more break in time? Thanks

ok i have 2 fi btl 18's, 2 cresendo 3kwp, 2 xs power 3100's, iraggi amputator 300a, big three. i jus have NEVER heard of anyone putting an 18" btl in a 9.5NET or bigger cu. ft. box per sub everrr!! and i dont really know what optimal its gunna be daily driver, i want as much SPL AS I CAN GET AT LOWER FREQUENCIES such as, i wanted to tune port at 32hz. HOW MUCH PORT AREA PER CU. FT.? i kno im a noob i on this forum but i know wat im doin everything except box specs. i was thinking up fire subs bo dimensions, 45"width x 41" depth x 24" height INTERNTAL DIMENSIONS ARE 42"width 38"depth 21"height, btw i was going to use two layers of 3/4" mdf all way around so total of 1.5"…

Hey guys I'm running (2) 12 btl on 4000rms tuned at 35hz. My low past freq is set some where between 75hz-80hz but no high past filter.I ordered an pfmod adjustable subsonic filter but I'm not sure should I set it at 30hz or 35hz. I would have preferred setting it at 33hz but it not an option on the filter that I'm useing. Fi recommend setting 2hz to 3hz below enclosure tuning thank guys.

i want to build a new enlosure for my 18 btl. ive never done any bandpass box before and now id like to try it. do you have any suggestions or a website were i can find a good instruction how to build a 6th order bandpass (calculator)? i have a suv and ~10 cft of space.

I am getting ready to build a box for a btl n2 18 and I found these cut sheets on the forums Fi links to from their home page. http://www.soundsolutionsaudio.com/forum/topic/44518-btl-box-cut-sheets/ The dimensions just so happen to be perfect to fit in my escape in the area I have left. I have 3 questions. Is this a decent box design? Is there any problem laying the box on its back to fire sub up port up? ( too close to back hatch I think to fire back ) And it shows the hole the sub goes in as 16 3/4 diameter. Is that right for an 18 inch btl? I figured it would be close to 18 inches?

I'm curious if you guys could build one for that sub? 4" coil, 10" spider landing Must use a spider spacer too. Which I have, it uses an inverted neo motor OD is close to 4-3/16" maybe 4-5/32. My calipars don't go past 4" lol thank you

I see a lot of people using the SSD to augment their existing home theaters all the time. Is there something that can be done to lower the FS? Maybe a different spider pack or gap adjustment. Thank you for your time and response, Chris

So I have a buddy that

So I just recently ordered a fully loaded Fi Q 15" and now I need to decide on an amplifier. I'm thinking either a Hifonics HFi2000D or a Hifonics Brutus BRZ2400.1D. I will be running them at 1 ohm. Do you think 2400 watts rms is too much for a fully loaded Q? I think it should be okay, but I would like to hear some other opinions.

Are they measured when the subs are new and stiff, or after they're broken in?

Im gonna get 2 12in BTLs and I was wondering if they could handle 3,000RMS or higher and not have to worry about it, and the sub would be a daily sub but fully loaded otherwise.

would a kicker zx 2500.1 be to much power for a loaded fi bl 18 daily?

So I guess this isn't really Fi specific but I've got this box modeled up in sketchup and I'm wondering if it would be beneficial to add an angled piece to each corner and to cut an angle into the inside turn of the port at the corner or if leaving it the way it is would be fine. I haven't ever heard a back to back comparison with two similar boxes, one with the angled corners and one without so any input would be great!

Hello Im building a box soon for a Fi BTL N2 15, and its going in a honda accord. But im tired of thinking that all the sound is in the trunk, so i was planning on removing the backseats, and build the box so the sub and the port would point forwards. (So the sub and port would be right behind where the seatback's should have been and the box inside the trunk. (kinda like this: What do you guys think? Would i get more sound pressure in the front seats this way? Or would it be better with the sub in the trunk and maybe port up the parcel shelf? Any ideas what would give me most pressure in the frontseats? Thanks alot

I decided to wire my entire system myself. My question is wiring the dual 1 ohm 15 " ssd to the MTX X1000D mono bloc class d amp. Im okay with everything else. Just need to know how to wire the subwoofer to the amp to 2ohms..The amp is rated 1000W rms at 2ohm. Thanks in advance.
