Fi Technical

hey whats up guys just got my box built from this guy that has built them for me before and never had a problem but this one just looks not right so i need help from you guys....the deminsions are....width is 48" height is 22" depth is 31.50 port hole is 3.75 x 22 port length is 27.75 and it is supposed to be tuned at 32hrtz...does this sound right or do i need to have him redo it thanks if i forgot something let me know thanks again

Just got this with copper coils. What gauge speaker cable should I use? I was going to feed it 700 watts RMS.

i did some measuring and the biggest i can go is 4.5 or less.. so ill have to get a bl 15 instead of the 18 that i had planned.. and i plann on getting a hifonics 1606. box tuned to 32. what you guys think. should i get any of the options. heres the box i got http://www.subwoofertools.com/forum/ported...mp;Fs=&CE=0

i have four btl 18s. is it safe to try to drill the terminals to make them just a little bit wider? i cant fit a full piece of 8 gauge into one terminal, i have to trim it just a little bit. and trying to fit two 8 gauge wires into one terminal i might as well just use 12 or 14 gauge because i have to trim the 8 gauge down so much its ridiculous. how bout taking either a unibit/varibit/stepbit (call it what u want), or a slightly bigger drill bit and try to make them bigger? extremely bad idea and i'm gonna end up needing to replace something because i'll break something? or be very careful and go slow and it will work? 2000 rms u would think u could fit a big ass wire …

I ordered recones for Konaki motors, if you can remember, I have the thread up in the General Fi section, anyway, I was wondering what type of spiders and coils you used in the recones construction. It looked to me like 3 spiders were used and the coils were copper flatwind. Also would like to find out what you guys would estimate the power handling (rms) of the sub would be with the soft parts you sent me. They are seeing probably 1200 watts each, which I am sure they can handle fine, I do not plan on upgrading my amp EVER, but I am wondering just out of curiosity what the rms of these things would be.

do anyone know what the prices will be to recone an ssd 12 2dvc Flatwind Coil?

2 18in btl's fully loaded 12 cuft tune 34hz Port wide 18.5 in height 5 in lenth 10 in That is 185 sq in 12 x 15.42 = 185.04 right? thanks

I'm about to purchase one to go with my JBL 1200.1 Plan is to make a sealed enclosure. I have up to 3 cubes to work with and I see that Fi recommends 2-2.6 What size should I make it? I'm looking for deep and tight bass. I love low lows and when the sub just slams. Other question is weight. How much does a Q15 weigh? Last question is can I run the full 1200 watts to the Q15? thank you

i want to get a 15" BTL and put it in a 1999 dodge stratus. i cant decide if i want a ported box with the BTL firing at a 45 degree angle towards the trunk and have the port firing towards the seats (i currently leave my back seat down, it is MUCH louder). OR go with a sealed box with the BTL firing towards the seats with my back seat down. i was thinking a Hifonics Brutus 2406 for it, which is 2,400 watts RMS at 1 ohm. i would get it fully loaded. PLEASE MAKE ALL THE RECOMMENDATIONS YOU WISH! another thing is the new BTL's, there is no triple stack magnet!?!?!?!?!?!? it is just a single magnet, why would they to that???

in my f150 ext cab with a 12" ssd with flatwind and bp and hifonics bxi1206

well not really, i still have to double baffle it, and carpet it. its 4.5 cubes, 67.5^2 inches of port at 34 hz.

hello, ive been looking on her for the past while and only see box designs made up for 1 btl 18. does anyone have anything made of for 2 of them? thanks

I plan on ordering a SSD 18" pretty soon and I'm attempting to make my own box. I'm only 16 and I'm not very good at math so if you guys could help me it would be greatly appreciated. I used the box calculator over at ssa and this is what I got. The 18" SSD needs 6-10cuft and needs to be tuned at 33hz, well I came up with some numbers and I got 19.5"H/ 36"W/ 18.5"D and after displacement that gives me 5.9cuft. And then it gives me the port length, area, and volume. (Port Length = 0.722 inches) (Port Area = 7.069 inches squared) (Port Volume = 0.003 ft cubed) What do I do with those numbers? I have no idea of how to tune a port or anything like that so I will need some he…

Hey everyone ! I got the aq1200d and the 15" BL ready but i made a ported box that i want to make smaller for more room in the trunk and its just a pain to get in. I was just wondering what is the smallest ported box measurements I could use to get as much as i can out of the sub while being tuned to around 32-33 hz. Please help! thnx

I'm currently looking at components to go with my 12" BL. I'm going to either go with Rainbow SLC 265s or SLC 265 Kicks. What I was wondering was with my box tuned to 32 Hz would my BL get loud enough up to 80 Hz to be able to have my high pass at 80 for the Kicks? Thanks

Not at the same time! I have two boxes built for my single 12BL. (D2, loaded, daily) One is 2.5cuft @ 32. Slot port. Homemade The other is 2.0cuft @ 32. Kerfed port. PTS They are both designed around the 12BL t/a parameters. Two questions. Is the BTL a substantial upgrade from the BL? Could I use the 12BTL in the same box which was designed for the 12BL?

So I got 3 15 in dual 2s wired in series tuned to 33hz on an audiopipe 30001d amp isn't turned up a little under half no clipping and as normal subs gets a little warm never hot enough to where u can smell the coils burning up. Now my issue i ran into today Is I was listening to them going to lunch with no problems and shut the truck off and came back out and just turned system on and how I can describe it is one of the subs instantly started to make a distorted rattling noise... kinda sounds like the sub is farting all lower frequency but not noticeable at higher frequencys. I pulled speaker out and the coils dont have any noticeable scratching or rubbing.. Now I'm just …

ok so I have used a few different calculators and got different lengths... the box is gunna be 4.0ft^3 for a 15" Q tuned to 32 HZ on carstereo.com calculator i got H 6"xW 10"xL 28" on winisd pro i got 6x10x 32.9 L?? what one should I got with or are there any other calculators I should look at? also what would my port area be looking at and would I be in the recommended 12-16" range? Thank for any help -Ryan

I've got 2 15" BTL's and the tinsels have snapped off. How can I get some replacements?

I have a 07 Tahoe and 2 BL dual 1 ohm 18s on a hifonics BXi 2010. I was looking to add 2 more 18 BLs in a 18cu. ft. ported box tuned to 32Hz. I also wanted to upgrade my amps to 2 RF T2500-BDs strapped at 2ohms. My question is will this be too much power for the subs? They are fully loaded for daily use. Please help. Thanx.

whats up guys. i need to figure out some dimensions for the btl 18" sub so i can fit it in my 1962 chevy belair. any adice would be greatly appreciated

i finally found a box to fit my beautiful babies! i just need to know whether to buy it or not. heres the catch. according to fi standards: Q 12

I am looking for a recone for an SSA Icon motor and was wondering if you could do it. I am looking for max SQ as it is going to be for home use with a pair of B&W DM603 speakers. I also need a basket, I am looking for a 12" recone and basket.

thanks everyone need a little help i have a new bl 15 loaded, enclosure 4 cb tuned to 32 hz, im trying to adjust my amp and head unit settings for this sub ive tried several things but i dont feel that its right... the amp is a hifonics bxi 2008d mono, and the head unit is a pioneer deh p7900... ok now ive played around with it a little and to get decent sound (bass) ive had to set this amp to gain level 3/4 up, and bass eq 3/4 up, subsonic a little over half way, and low pass a little over half way... and the head unit settings hpf 80hz, (sla) all way up, loud off, sub 1 normal, sub 2 to +6 and im guessing the band thats on this setting with this is the low pass at 100…

Can anyone recommend one? I purchased a dual 2 ohm Fi BL 15 and my current amp does not have a subsonic filter (which the install guy says will be needed to best tune the system). Some of the amps on the SSA website don't tell me what load they are stable at in Mono.
