General Fi

Hello folks. I been a forum lurker for quite a while. I happened to run across a pair of Fi X 10 inch preproduction models. I have no clue as to the specs of these. A guy locally has them for sale..and I was very interested in them. Would anybody happen to know the specs(rms, suggested enclosure size) on the X's as I assume they were from the first run of the sub. Thanks

Let's drop all known FI video's and links on this one soon to be sweet thread so we'll all have access without looking all over man's creation First up Daytona Spring Break Nationals 2007. The settup is 8 15" BTL's dual mags with 8 Kicker 2500's modded I think. Watch this video and then ask yourself what a triple mag should be capable of. This video is very impressive and the owner of the van is none other than our own Shawn Fleming. FI BUILT TO LAST I'll be back with more. Let's see how many you can find. An FI scavenger hunt. 1st place-A cool thread !!!!!!!!!!!! Ready set go!!

i ordered a fi btl and it was suppose to arrive yesterday. I was at work and wen i got home there was no note on my door so i can pick it up. Nobody was at home to sign for it so wat should i do? Do i need to contact UPS?

Im looking to buy a FI 15". The sub will be in a jeep. Which application would be the best? I was thinking about the BTL. For the most SPL which options should I add? Also what type of amp should I be looking at? Im not trying to spend a ton on an amp. I found a nice Planet Audio thats 3000@1ohm. Me and a buddy will build the enclosure. Let me know! Also...is the BTL alotttt louder than the BL?

Wondering if anyone has matched a passive radiator with the Q 12 before? If so what radiator, if not is there any recommendations? Looking at making a home theater sub

I have a new 15in Q that will be going into roughly 3.5cu after port and displacement. Would it be ok to use one 6in round port with flared ends? Looking for 28-29hz tuning. I can do 43.75sq in with a 3.5 x 12.5 slot port but the box will be much more difficult to build. Which would sound better? This will be a console style box, sub forward and port will fire into the side wall.

Hi, I have a strange issue that seems to be getting worse. Ill start from when I think it happened. My friend and I built a 4CF box for 2 FI SSD tuned to 30HZ. When we put the box in my cobalt I noticed that the wire terminals were upside down. I didnt care at the time I was just wanted it done for the time being. This was back in 2010. A few weeks later I decided to have my other buddy help me remove the box and put it in the right way.and reposition the subwoofers so that the labels looked the right way. When I was reorienting the subs I unhooked one completly to show my buddy,turns out when I hooked it up I wired the coils out of phase. I didnt know until I was on my w…

Whats the major diff between a 15" FI BTL and a 15" Ascendant Audio Mayhem? Features and Nitche market.... I mean, I thought I read that the same guys designed and build both.... Both look pretty sweet... I would not mind owning either... Just real quick as I'm at work, was crusing the net on break but the biggest difference I saw besides cosmetics was the Mayhem has Silver 8AWG Push terminals 2500W RMS vs the BTL Did not see anything about the terminals listed on the site for the BTLs 2000w RMA Looking at all the Parameters most of the specs seem pretty close... within a digt or two... I'm sure there are others, but thats all I saw in the time I had.... Just curious …

Whats the average wait time for a couple sp4 15's?

I have two sealed subs 47L enclosures built around the Peerless 830500 driver. This driver is rated at 12.5mm xmax. Details here: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=297-608 Extensive details about my sub here: http://www.linkwitzlab.com/thor-intro.htm Bottom line is that I would like more output as I am bottoming my existing subs. I'm okay with building new boxes but ideally I would like to use the same crossover as it is tailed to work with my main speakers (Linkwitz Orion) Assuming that the 28mm xmax spec of the Q12 is one way rather than p-p, this driver should give me about 6-7db of headroom. I modeled my 830500 vs the Q12 in WinISD and the re…

Props to FI,as i said we are getting ready for a 3x dbdrag in Pa. so i slapped a box together to give me a starting point,lol,,and i didnt expect much out of it because we hadent tuned the encloser in yet as to my suprise it burped a 148.3 in the zx3...enough said i couldnt ask for a better starting point...i think if i can stabalize my voltage and build a few more boxes i should be able to run into the 50s.

Fi SSD 18" = 229 GBP = 327 EUR = 425 USD = WTF ???..and either way i have to pay +20%tax+shipping) my question to guys from Fi would Fi send the sub(SSD 18) to Slovenia (with UPS) ...how long would it take and COST ??? you would make a VERY HAPPY BASS ADDICT …

Hey can someone help me find a sub grill that will work for an Fi Q 12"? The one for my old type R works but im worried about the edges because the FI has that rubber rim that sticks out quit a bit.

I'm desperately seeking a recone kit for my Avalanche 15. I've had several people suggest that Fi Audio might be able to help me. Scott is a name that has been mentioned on a few occasions as well. Can anyone get me in contact with Scott, or help me find a recone kit? TIA!!!

Hi there i have an 18" BTL the older style one with the tripple magnet and while taking out the whole system so i could design a new box i pulled out the sub from the old box and spotted that the spider on the btl was ripped in about 2-3 places 1 of them being a noticeable rip and the other 2 look like there about to rip and also i found out that where the spider is glued to the cone the spider was coming unglued in a few places. I wanted to know does this mean that i need a re-cone or is it salvageable, pictures are below, the pictures below are of the major rip one Thanks

I was wondering if someone can give me a qoute for Fi BL 12 shipped to Hawaii.(zip code is 96792) I want to order 1 next month

Okay so i went to Freemans Audio today to give the guy my idea of what i wanted to do with the box. I arrived with the intention of sealing off the trunk and having the sub faced towards the cabin.... the guy said that it would be better to have it in the trunk facing the trunk becuase it would resonant off the trunk, if it fired into the cabin, i would be the first thing it hit... For "my way" wouldnt there be less trunk rattle and it be louder to there ear? versus "his way" would have more trunk rattle and some of the sound would be sealed in the trunk??? I dont have to long before i have to tell them my final plan... tommorow they will most likely start working on it a…
