Fi Technical

Hey guys I have a question about the Q series woofers: a 12 Q in a ported box or a 15 Q in a sealed box is what I am debating now given a 2.5 ft box for either one: 1.) which will be louder? 2.) which will play lower? 3.) which will have better SQ for rock?

Got a 12" Fi BL that needs reconed but was curious if I can recone with a totally different brand ie. Incriminator, Ascendant, Sundown, DD, etc

What does the flatwind coil and bp power options do when buying the subwoofer? Im new to Fi and what the subs for spl.

My enclosure is built at 2.5 cuft, my current port area is 10x4x21, tuned to 39 hz, I want to change this so its tuned to 32 and I would need to add 14 in in length, unfortunatly not possible. So I looked into it and I could change my port to 10x3x25, what will I lose(or gain) by changing the port area ?

would one of this be good or two for a pair of 18Q's...?any other suggestions on an amp is welcomed. http://www.woofersetc.com/index.cfm?fuseac...Product_ID=1818

Ineed a box for 1 18'' needs to be sealed.I can build one,but dont have the resources nor will my park let me.Stupid country club noise regulations.Shops only build 10s & 12s around here.Can someone help me please?

New to Fi and just picked up a 18" btl. Need some suggestions on box size and tuning. I have about 10 cubes gross before driver and port. Looking to do a sub up, port back, tuned to maybe 35hz with 4k of power. A few have said that these have tremendous bottom end so I'd like to tune appropriately.

Hey. I going to have a 12" ssd with copper coil and the kicker zx1000.1 amp and i was wandering if i would be alright using 4 gauge power and ground wires because thats what i had for my old setup which wasnt as powerful...or should i just run 2 gauge wires???

Will be doing a 4th order for a single 15" Q. Was going to make the sealed chamber 1.8cubes and the ported chamber around 4 cubes and tune around 44-48 with 16-20" of port per cube. Does anyone see any issue with this...

I read the recommendations for each speaker, but still have a few questions. First, I'm going to be ordering a dual 2ohm fully loaded 15BTL, Its going to be for daily with roughly 2500rms to it. My question is, is going fully loaded the right choice? Or will some of the options hurt the power handling instead of help it? For instance the universal option because of the gap size? thanks for the help

So heres the deal: I bought 2 12 X's A few months back during the clearance, and I put them in a horrible prefab ported box with circle ports and after about 2 days, a blown out side panel. Supposed to get 1.6-2.2 cuft in a ported box, I think theyre getting 1 each. It sounds decent I guess, but if I get it past about 1/3 volume, I get the worse port noise I've ever heard. I just got back from Home Depot, and I bought a 4x8 sheet of 3/4 MDF. I'm planning on starting the construction of my new box tomorrow. I've decided on sealed, because to be honest, theres about 0 chance of me successfully building a ported box. Here are the stats for the X series 12's: Sealed box: .9-…

Any chance I could get approximate T/S Specs for my re-coned subwoofers? The hybrids consist of Memphis 15-MOJO15Q1 (15" Quad 1 Ohm Voice Coils) mated to Fi D2 soft-parts with older style tinsel leads. I purchased these already assembled from a friend but he didn't have any specs on them at all. Any help would be greatly appreciated. Thanks, Charlie Buffalo

Is it ok to feed a single BTL 12" with 3000wrms daily? any issues you think I may encounter? thanks!

I was just wondering, if when adding a port to your box do I minus the width of port and then I'll have my true area of space the actual woofers will be in?

right now i have 1 12" ssd fully powered in a ported box. it is 16X22X14. it sounds good and i listen to almost everything from rap to techno. I was wondering if it would be better to switch to a sealed box? i mean one advantage would be less used space. and which direction should i face the box also...

I was wondering if it would be possible to use a Q 12 in an infinite baffle setup. I would only be using around 300-400 watts. Any help would be much appreciated. (I know Fi has an IB sub, but since I have the Q already I would like to use it. If not then ill end up selling it and get the IB3 )

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 need a box for meca event the 20th here is what i have to work with 18 tall 24 deep 49 wide please help i'm try to break the 50's sorry it's in a 98 tahoe

hi all i have been planing a blowthru on my 01 tacoma using two fi q 18s and two soundstream trx2000ds. now i have come up with a few ideas for a box but was wondering if there were any pros out ther that would like to offer up some advice. i was thinking of having one sub on either side with a center slot port ond a combined volume of 22 cubes tuned to 28 hz. also i have heard pete from ttb has some great designs but he hasnt gotten back to me yet thanks

Hey, So I got a 15" Q D2 right now and just sold my crappy amp. I'm planning to get either the SAZ 1000D or a SAE 1200D. Which would be better if eventually I will get another 15" Q D2?

Ok I have a 07 Saturn ion I'm going to put in a q18 in the trunk. The box from the cut sheet for a ported box won't fit.... My trunk is 14.7 cf so getting a 7 cf box in there can happen I'm just clueless on how to go about it. My opening is 19x40 Ball parking that. of course there is the angle too... Any tips or ticks to get this built and in there would be very helpful. Also I hope I posted this in the correct spot.. Also I feel havering the sub firing tends the trunk lid would be my best bet

What are the differences if both would be ran on a sundown saz 1500? I have a fully loaded bl now and it's not as loud as I expected. Would the 2 12 in ssd subs be louder?

ok i plan on running 2 SSD 12's off a AQ1200D @ 1 ohm. the box it gonna be roughly 4.4 cubes depending on how much the aeros take up for space. what would you guys suggest for aero size? i know i would need less port area for aeros then say a slot port but im not sure how much less i can use. i was thinking 1 6" aero which would give me 28 sq inches of port area (6.27 per cube) or i was thinking of going with 3 4" aeros which would give me 37 sq inches of port area (8.69 per cube) now i know thats less then the recommended port area for slot ports but i was wondering if either of those would be acceptable for aero ports.

Can it be sealed and sound just as good ported?

Ok i wanna take a go at the blow throu deal. Can anyon help me ? I need tips. Do i make my port the blow throu part or just make the box and set port infront of it. Wat are some ways to make the box weather proof. How should i make the blow throu on the bottom or standing up? Thanks
