General Fi

well im sorry to say i wont be able to get a 15" btl. because my wife and i found out were going to have a baby. so i was thinking about an SQ setup. with a 10. probably a Q10. and i am thinking about building a fiberglass box for it.. how would i go about doing this. what size and should it be sealed or have a little port. so i hope to do this. sorry about the btl thing really really wanted to get one of those. so yeah. thanks.

lookin for some pics of a 12" bl side, top, and bottom and a review if anyone has one on the 12 thanks

will banana plugs fit in the push terminal on the bl's

I was just curious about the specs on the lineup,specificly the Q.Maybe its just the picture but the Q18 looks like it has a small mag.Whats the weight of the whole sub?whats the mag weight in oz?Im sure its designed for that application but the BTL is the only sub that looks proportionate.Dont get me wrong everything Fi does I like.My eyes have a hard time with big sub little mag.Hope this makes sense to everybody!

Ok, here's my question..FI is obviously amazing. I want one!!! I'm driving a 99 Malibu and I want to put a 15"Q in. I'm trying to decide if it's worth it for me to build an ABC box, a standard ported box, or possibly a CRX box. I want clean and loud...don't care about the complexity of an ABC as I find it fun. My only problem is that I deisng an ABC box at 3.5cu ft, 30 hz tune, with 50 sq in of port area. I'm not sure if taht's enough port area. I will be powering the sub with an MTX 6500d. Any help would be great!!!

I'm sick of my mediocre system, and its only been about 3 weeks. My DD m1 did eventually turn on, but is emitting a lot of rf noise. So yay for new amp. I am looking for 1200-1500 watts @ 1 ohm. My budget is 600 dollars. To power a 15" Q. Current prospect amps: US xt4000d DD M1a Diamond D6 1500.1 Electrical Upgrades: None yet. eventually a 180 amp excessive amperage alt and a kinetik power-cell. Power wire is currently 4 gauge with a 150 amp mini anl fuse 8" from the battery. Big 3 is not done yet, it has been too damn cold. The internal Box dimensions will be: 14" tall x 20" deep x 26" wide. 48 sq inches of port (4"x12") 25 inches long Box will be constructed out of 3/4…

Hi i'm in the process of building my box for the 15" BTL, I wanna know how long the port will have to be to have a tuning of 32hz. My dimensions are 40 x 20 x 20 with double bracing 3/4" MDF. i did the math and with the double bracing, the internal volume is roughly 7.5 cubes. I wanna know how long the port will have to be at 4", 5" and 6" tall. Thx guys, Fi rocks

im getting an explorer XLT and im wandering how 4 18" q's sealed would do VS. 2 18" BTLs ported. which would get louder which would sound better? im thinkin that the Q's would win both scenarios but i thought id come here to see what everyone thinks...

Please Send me your Videos of your Fi Subs. Any and everyone you have. Please tell me the Specs of the system. Sub, Amp and Box... Thanks guys...

Hey guys, I thought it would be a good idea if we could have a place to check the status on our subs upon request. With the new contest, I thought it would be a great addition to the board. The UPS tracking number is one way to check, but when your in my situation, about 4+ days for an SSD, I think it would be nice to know how your sub is doing, and when it will ship out. I know the guys at Fi are busy, and although this would be a great addition to the forum, they have the final call if this thread is a go. So I will start. Please include your name, e-mail, day payment was recieved, and type of subwoofer.

Welll I have already decided to go bigger(And i love building things)...So this box is up for sale. Its only been used for a week, but will stay in my jeep untill its sold...if its even sold. I didn't build this to sell it so I'm not asking much... 110 + Shipping... I will replace the carpet before hand as I ran out of carpet the first time lol so the bottom part isnt fully covered... 6 Cubes @ 32hz with 95.6 Sq/in of Port Area Box Dimensions are 16.5 X 45 X 24 Sounds AWESOME...

Well today I decided to finally pull the trigger on a 15" bl. Lately Ive hear that the SQ on this woofer has been better then people expected while still wangin I built a box last weekend and its been sitting in my car, and I just couldnt stand the though of an empty subwoofer box just sitting there. I will definately post a review + be on step closer to a free shirt woot! Thanks guys Im really looking forward to seeing what this baby can do

Hi I just got my 12" BL and I'm starting the box for it. The box will be about 2.6 ft^3 and tuned to 33Hz I was just wondering if a 3" port would work or if i should use a 4" port. I'd like to know if there is any difference in SQ or output with a different diameter port.

How come it drops off so bad at 60 Hz where other subs do not? http://bigbassman.realmofexcursion.com/sub/ssd.htm

Well, around december i received my 12" Fi Q from my uncle who knew me too well i guess. It was given as a gift. So im going to break down this topic into the reveiw first, then into my ?'s Packaging, First Impressions: Upon opening the box, the sub was wrapped well and contained in a nice packaged box. only one of the blue things were somewhat worn, so it was slopped down a little, but as i said it was a gift, and probably not handled the best. But still was in perfect shape When i opened the sub up to take it out and expect at the house, the first thing i noticed was how nice the magnet frame was painted. No scuffs. Later, after more inspection i noticed how stiff the s…

Well to begin, I will report on my expierence with FI customer service! I ordered through the site and paid with my paypal account, the site was very easy to understand and use! Once I ordered, I began harrassing Scott with all kinds of annoying questions. Scott answered everything I asked as best as he could, without complaint! I even sweated Ndmstang a few times, he too was helpfull and understanding. So all in all customer service was top notch. Tracking was so so, UPS sucks in my honest opinion, that has nothing to do with FI at all though! They rarely updated the info for tracking, it always looked as if my sub was just sitting around. I am biased though because I l…

Alright so I have had my system in for a couple of months now and I have finally had some time to really get to know it. Now that the hype of having a new system is over I am starting to listen to my normal music and not just rap, so thats stuff like 311, Eve 6, and Modest Mouse. And i have to say is that, it sounds amazing for being a 15. It keeps up with the fastest drum kicks and its clean and crisp. I could not be happier with the SQ of this sub. Before i had 2 10's and those were amazing for rock but this is just as good if not better, I got the benefit of being much louder and having lower notes but did not give up any accuracy! Now for the SPL side of the Q. This …

I know SQ is rather subjective, but what are some opinions of BL compared to the Q. Maybe the easier way to do it would be rating each on a 1-10 scale, not sure. Either way, I would just like to know any and all opinions about the BL sound quality. Feel free to compare, rate, whatever. Thanks!

i really liked this pic so i copied it, but now its gone well its back im pretty sure its a 12" Q any pics from before please share them here THANKS these are some 18" Q pics

This summer I will be looking to upgrade my system. I am strongly considering an Fi product, but I do not yet know which one. I guess my question is what the minimum and maximum power you would suggest running on the SSD, Q, and BL. I would not be purchasing a BTL due to power requirments. I certainly do not want to blow a new sub, but I do not want to underpower them either. So, what is the power range, as well as optimal for each of the three? Thanks

Hello. I have only recently entered the world of Fi. Before the BL came out, when I was first looking around, there was another line of subwoofers. Are these still available thru Fi or not? If so, what are the specs on them? I did not think to record them before the X disapeared from the site. Thanks for the help! Ben

Wow so far these things are amazing. one problem...Only have one md2 working sucks but still amazing. here is some pics and a nice little flexing vid. Ill post some more in a little. Da VID...

Two fully loaded btls on a memphis 4kd 12 cubic foot box @ 34 hz. Straight up nasty. These vids suck but i worked with what I had. Anyways... O hell yeah....Dirty car sucks...

Recently I purchased two 12 inch ssds from Fi car audio. I was looking for something loud yet retain good sound quality. I first built a box which is 4.5 cubes tuned to 33 hz. I have them hooked up at 1 ohm to a US amps Md2. At first i thought the low end was lacking so i contacted scott and told him and he told me about the copper coils vs the aluminum coils. Well the copper coils made that much of a differnce because i love these subs. They play the lows nicely and get loud. The sound quality could be better. But being that im a bass head it doesnt bother me at all. Compared to a sx which everyone wants to compare them to. I would say they are alike except more musical …
