Fi Technical

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 )

Ok here is my question, If I cut the circle out to the circle in the specs will the SSD fit in there ok? If not what size should I make the circle. Here is the plans (I changed up the baffle so it would not be between both sides) Pics:

i got rid of my RE SE 15 recently. ran it in 3 cube sealed,amazing lows, but looking for more output sealed if poss. could i expect more output with a Q 15 sealed due to higher excursion than the SE? if not and ported is the only way, will the Q 15 work well with a 28hz tuning in a box smaller than 4 cubes? my goal is amazing low end extension like my SE had sealed, just louder. i dont feel that a Q 12 will be capable sealed of this compared to the RE 15. amp is a Sundown sae-1200d

i'm looking for a speaker box plan for my fi bl 18. would this box work or should i go bigger? http://img35.imageshack.us/my.php?image=5c...hz62sqin6hk.png

i have 2 jl w7's 12inch, that are both froze, is it possible to recone them with FI recone kit? i was kinda new to this recone stuff sorry, if you can help me i would appreciate it, i would actually rather ship it to FI but i cant ever get ahold of anyone. thanks

I have a 3.5 cube box in my truck. i was wondering your thoughts. what would be louder? i can only mount the 12s down fire but i can mount the 10 into the cab? ant thought? thanks subs ran of a saz1500 for now

hey guys, I have a wedge box that goes behind my bench seat in my truck. its about 2.8ft3 before sub and port displacement. right now i have a 4in round port that is about 7-7.1in in length. so that puts me at about 35hz tunning wize. however i just upgraded my amp and bought a SSD. so i want to mkae sure for port is good. i will be re tunning to about 33hz so that will make my port longer. however should i upgrade to a 5in round? i dont know much about what would make a good port. i thought as long as it was tuned to the right hz it didnt matter. please offer any advise. i cant wait for the SSD to get in!

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?

I am debating if I should dampen the custom box when I get my 12 fi bl 2ohm. Also what do you guys think about powering it with a PDX 1.1000 at 4ohm ~1229 rms?

I have my 18 bl and my car now so im ready to construct my box to fit my trunk. Ill be running the sub and amp at 1000rms at 32mhz. The trunk has alot of space but im worried about putting the box into the trunk so if anyone can give me the proper dimensions for 32hz please let me know and does anone know a good calculator tool for this so i can calculate the port size also? THANKS!

alright guys i have just ordered a 18" btl 18 dual 2 ohm and was wondering what is the possible wiring options that i can run it at ( what ohm ) thanx.

Sorry if this is covered elsewhere but I can't seem to find the answer im lookin for I've got two alpine pdx1.1000 rated at 1000w rms. One of these would be underpowering a btl rt? And I couldn't run two to one sub? What would you guys do? I have an audi A4 so only one huge box would fit in my trunk

like the topic says im experimenting with my RE MT to see which coil amp combination will work best, so I would like to know thanx guys , and is there a longer version of the original dual 0.7(actual quad 1.4) coil ?? im in dire need of xmax to get louder... im hearing slapping when i get that sub moving alot( could i be bouncing off the dust cap? I dont think im bottoming out)... last time i ripped the coil right off of the spiders (quad stiff) that was with 4 ab 500.1 gain all the way down ( only got them to produce 75xx watts before sub exploded)or should I be using a different basket with 10" spiders? btw this is a 15" with 12 spoke basket

I'm seriously considering getting a Fi BL 12 and was wondering if the amp I link to below this would still be a good choice. Thanks in advance. http://www.db-r.com/sell/store2/index.php?main_page=product_info&cPath=65_67_69_105&products_id=248

Configure Speaker: Ohm: dual 1 dual 2 P Chamfer: no yes +$10 Cooling: no yes +$40 HiXmCoil: no yes +$20 Daily or SPL: Daily SPL Induct Heat Ring: no yes +$25 Universal: no yes I can't seem to find what these options mean and/or how eeach affects the end product and I would like to order a couple of the Fi 18" BLTs. I will be playing them daily. Does anyone know where these options are explained so that I can decide what to choose and why?

what would be a good box for 2 15" bl series subs.

Im going to get 2 12" SSD's if i want to wire them to a 1 ohm load should i get the dual 1 or dual 2 ohm. subs.

Am using two Q 15s but in to seperate cambers that are in 2.9-3.0 cuft enclosures after all displacement, is this too small?. Would it be better to use a single or a dual camber? I was told that the single would hit harder. What do you guys think? The box is tune to 30Hz using a port that is 2 X 14 and 16.75 inches long. Am still in da building stages so i can change some things just alittle if its necessary.

what is the difference between dual one or dual 2 ohm??? im looking to power up at btl 18 will 2 rockford 2500?

I was just wondering if it was possible to replace the push terminals on the BTL with the terminals you need a hex key to open and close, could someone also tell me what gauge wire will fit in the push terminals. I don't have it yet, I'm just asking if its possible.

ok, gonna be fun fitting this in my grand am. removed the double fold backseat. and plan on put a box running all the way from the trunk to behind the driver seat here are some plans for the box its about 9-10 cubic ft right now. questions? shape dosent matter dose it? do u think ill need some more support? how big should i make the port?

How are you guys/gals fitting such long ports that are necessary for the Q12 into not very large boxes (1.8-2.5 cuf). I am designing a ported box for my single Q12. (2.2ish cuf @ 32ish hz) I am looking at a 6" port that is around 30 inches long. Is everyone using slot ports with multiple bends? I am not looking to compete or steal any secret designs. I am just looking for suggestions of what other people are doing to port the Q12. Thanks.

I am going to use my 12" in a room setup for listening to music, it will be on a 500 watt dayton plate amp. what size sealed enclosure would you recommend, looking to keep it under 2 cubic feet.

Would you recommend multiple ports are a large single port for 2 Q 18 D1s with cooling and the extra spider on an AudioQue AQ2200d, in 20 cubes after displacement tuned to 28 Hz? Car is a 2004 Tahoe with the max box dimension limits being about 27 H x 49.5 W x 36.5 D. I had a few designs floating around, I think one was with 4 8.5" round ports, one with two slots along the bottom of the box, and one was a rectangle in the center measuring 15.5 H x 19 W, so 294 in^2s area and was 22.35 in. long. The dimension limits leave about 7-9 inches between the box and the rear, 7 at the top and 9 at the bottom. I was thinking the large port might not have enough port speed, but …

What is the best option setup on a BTL for SPL use only and how much power will they take for Burps only?
