Fi Technical

I have 10 foot of it to go from the box to the amp, and while I haven't seen the sub yet, I'm having a hard time seeing 8 gauge in a 1ohm configuration on the coils. Will it fit? Or should I use 12 gauge for inside the box? (This isn't really a question about power...I already have 10 foot of 8 gauge so it's more availability. I'd have to go buy anything but the 8 which I have)

Hey guys, Im really hoping someone can help me out with this..i purchased a sp4 about 2 months ago,but recently put it in my car 3 days ago as i was waiting until i had everything i needed to run my setup properly.. amp gain was set with an o-scope so no clipping and also radio was under point of clipping also. (amp -sundown saz 3000,cd player pioneer avh-4300, all 0 guage wire (monster) and a 270 amp alt from dc power..and some deka d31 batts.I pulled up home and after i turned off my car i noticed a smell comiing from my trunk and opened it and heard what sounded like flames burning. there was a lot of smoke coming from my port and it would not stop so i hurried to pul…

currently running a sundown saz1500 powering a fully loaded 12in fi bl in a 2.5 cu ft box tuned to 34 hz. I was recently at a local audio shop and had the main guy set my gains properly so i did no have any clipping. I was not very impressed with the outcome. As i come to find i had been running with clipping since day one and my system is now quieter. He told me to tune my box to 40-42hz and it would be louder. My question is how much louder? and will i still be able to play most rap music? What would be the lowest tone i could safely play?

Look at title. As an example, a 15" Fi SSD both D1 and D2 have the same specs except for a 40% higher BL on the D2, can someone please explain what is happening that makes this configuration have that much more motor force?

Is this possible I can't really find the tech specs of the two anymore so im not sure if there are any size differences between the two

Site says the cutout is 14.125 what does that equal out to? I have a router jig, is it like 14 1/16? Or 14 1/8?

friend wants to buy a BL 12 and place it in his car. he wants it even with teh rear seats so its a bit tall of a box. does this look proper for such a sub? http://imgur.com/a/IUDaJ

I am just trying to find the T/S parameters for the heat ring option. I am wanting to add it to lower inductance but wanted to know what the new inductance would be. Secondly I will be putting 3500watts to a pair of Q 15's and dont believe I would need any extra cooling options. I will add the chamfering option but being on a tight budget I will probably skip the Bp/cooling option and just go with the standard Q. I also wanted to know what the Mechanical Xmax is? I only plan on using these to Xmax and less but I do like to know all parameters of my speakers before pushing them. Thanks for any help from anyone.

Is 5ft^3 net to much for a BL 15 running on 1200wrms?? My plan is to make a box with an 8" or 10" PVC aero port. If Im correct... 1. With 5ft^3 net and an 8" port would give me 10 in^2 of port area per ft^3 box area. 10 in^2 seems to low... 2. With 5ft^3 net and a 10" port that would give me 15.7 in^2 per ft^3 box area. 3. But FI recomends running 4ft^3 box and with an 8" port that would give me 12.5 in^2 per ft^3 box area. If I tune my box at 32hz which option would work the best for daily use on all types of music?? Any help would be aewsome.

So I've had this Q since 2009, bought it off someone, and Im gonna order a recone for it soon because the surround got damaged, just wondering if its possibe if anyone can look at it n tell me which options it had? it was dual 2 ohm coils. Only thing i can tell is im pretty sure it didnt have the cooling option. thanks in advance

I was wondering if 11.25 net tuned to 31hz and 166.25 square inches of port is too much for 4 fully loaded 12 inch BL subs running off of 6,000 watts of power?

I am thinking about getting a pair of fi q 12's I am going to be running them ported in a daily trunk setup on a Saz-3500v2. I am getting the cooling option for sure but for I am not sure if I should get the extra spider & the internal lead options, I am thinking no on these options but I would like some opinions before I drop my cash on these subs.

Is 12 cubes net tuned to 31hz too much for 4 BL 12's? How about 140 inches of port?

Did the guys at Fi re-evalutate the SP4 and change the RMS from 2500 to 3000 watts, or did they redesign it to increase RMS?

Would it be smart to run the BLs down to 0.5ohms for daily use if I upgraded all my electrical? The amp is an Atomic 3000.1d

Thinking about going with SP4 15 inch subs. Anyone can help with how many cubes I should build too and how many inches of port? Will be running them on about 6K of power. Thanks

I have 4 FI BL 12's and was wondering how many cubes net should I build an enclosure for them? Also how low should I tune to do hair tricks? They will be seeing a little over 6,000 watts of power.

http://imgur.com/a/lNcLR#0 i have two sets of images its this album. a 33hz tune and a 36hz tune. i intend to build the entire box minus one side (leaving it to be held on by only screws) and change out the port as i test the subs volume. once i have things set ill glue on the final side. i would greatly appreciate it if someone would check my math and offer and criticism on what i have laid out here. thank you very much.

ok so the ssds are rated at 1000w ... so if you have them fully loaded ... what would that do for the rms power handling?

Can I get someone to assist me with an enclosure design for dual SP4 18s. Max dimensions are 27L x 30D x 30H. I'm currently running 2 15s and wanting to go with 18s. Power is a non issue since I'm now using two Crescendo 3.5ks. If this is possible please let me know. Looking to order the subs this week.

I own a BL and am buying an SP4. will this box design work perfectly for the SP4 and well enough for the BL? did i screw up on anything? at the bottom of my port i have bracing crossing it, will this be an issue? should the port be fully open down to the bottom of the box? i could not find any great info on port area for the SP4 so im sitting a bit over the 16 multiplier right now. i was thinking of adding a bit of that fluff to the box to make the sub feel it was in an enclosure closer to 8 cubic; is this a good idea? im going for SQ at high volume, or at least as much SQ as the SP4 can give me. what should i change, all opinions welcome. thank you. http://imgur.…

I just built a new enclosure and was wondering if 118 inches of port tuned around 31hz ok for my 4 fully loaded BL 12's?

Hello all, I'm planning a new build and was going to use 4 DAD BD woofers but have been also looking around at different companies and wondered if anyone could compare the DAD BD's to the Fi SSD. I already own a BD-15 and love it, but have no experience with Fi audio what so ever. I'm going to run either 4 15's or 4 12's (most likely 12's) in my 1999 Subaru Impreza on a Cactus 5K. I need to get loud at fill tilt but sound good a lower volumes, my DAD woofers do this VERY well. If anyone has experience with these two woofers any info is appreciated.

My BL just stared making the noise yesterday, the sub is hooked up to a MTX TA81001. The gain is set at little over half. I really hope the voice coil is not going out.

Hello everyone If anyone has the free time and could come up with a simple box for me that would be great. Id like to run them sealed and i will be giving them plenty of juice. ab 400.1 @ .5ohm. I have the electrical to back the amp up. The box will be going in a mazda 3 hatchback. Thanks for the time. Give me a email address and ill send over a few bucks via paypal. Thanks again.
