We recommend 12 to 16 sqin per cuft of enclosure for most ported applications. Scotts phone...

Looking at half that or less for the kit. Shipping depends if it is a kit or a complete recone. Stuck in Denver... stupid planes. Scotts phone.

We had a bunch of them go out on Mon and Tues. I will get a list going when I get back from SBN... if your names not on the list, well sorry... no shirt for you (or atleast I dont know you need one yet ) I figured adding the www.ficaraudio.com to the stickers was only an invitation to problems. The plain Fi logo could be for just about anything. For the larger 12" stickers, I do have some of the web address that can be added underneath for those that like to flirt with danger Thanks, Scott

If its a 3" coil Im sure I can. Ill have to do a little research on that one when I get back from SBN. Thanks, Scott

All orders up until this morning have been charged and processed. Your status on the sub might not have been updated yet... but we did have 3 BTL18 orders on the 16th (not sure which is yours) but all have been processed and paid for. We are trying to get ALL orders out before mid Thursday as 2 out of 5 Fi people will be heading out to SBN in Daytona. While I am gone, we will still have production going on some items... others that need heavier machining will have to wait until late Monday to be finished and shipped. I am sorry about the delays for SBN Thanks... Scott

2 cuft tuned to 32Hz will play the lows with authority. Definitely need to set up the subsonic filter correctly (28Hz or so). You should be set. I have told people for many years that FS is not an indication of bottom end extension (well it can be for IB and some other applications... but it really isnt much of an issue there either). Otherwise those that are using BTLs with an even stiffer suspension and often similar moving mass wouldnt drop deep (and I think they do ) If there is anything else I can help with, let me know. Thanks, Scott

The universal feature does allow for any of the coils in that series to be swapped in and out. But it sets the gapping relative to the pole tolerences selected (SPL or Daily). With the SPL tolerences things are much tighter and are designed strictly for SPL. With the daily tolerences things are designed to have a little looser gapping to allow for less coil rub and rock issues for daily applications. For those that wish to use a sub for both daily and weekend SPL, we recommend the daily versions. Can he run the SPL subs daily? Probably, but we do not recommend it. Thanks, Scott

X10 $109 X12 $119 No provisions for sales via the site anymore... we do still have parts on hand for them, but will be rolling those into another company shortly. If you want to order one, please send an email to [email protected] Thanks, Scott

Tom, I have some anti-bunch thongs screened for you. We got you covered

Mellow out people...sheesh. I like this place because we NEVER have the need to flex mod powers or have snide comments. Im definitely not a fan of pissing matches, but apparently since Im a hot race horse (per another post ), Ill assume I can pee like one too. Per FEA it comes in at 26.7mm. With rounding up it is 27, rounding down it is 26. 1mm would never make a difference in this case and is safe to say that coil deviations at the ends for lead out would have enough one way or the other as well. Along the lines of JimJ... its nie to have Xmax, but if the balance of the specs dont fit the application, it really doesnt matter much if it moves more. Thanks... Scott

I like it. I know its drawbacks and abilities fairly well in having used it on a few drivers and having played with it LOTS in the past couple of years. It is being used for a new lineup for a HT company I do OEM for and Im sure itll make its way into other products Thanks... Scott

Its not that they cant be incorporated together, its just that in many instances it creates way too much weight. There really isnt a point to making a flatwind copper coil that weighs 400 grams, just to do it if it doesnt have a benefit (especially for the extra cost). And making one that has similar weight and sizing to the current round wire copper coils so that it has optimal benefits for TS params... is somewhat of a waste as well. We try to optimize things for cost and performance. Doing it just to do it really doesnt make much sense... kind of like adding a 3rd magnet to the older X series as an option and charging more for it simply because we can. Doesnt do anything, so we dont have it. We are working on more options for drivers, but we want to make sure that they provide a solid difference or gain before we offer them. I can add 50 different things to the lists simply to "hook" people and rack up some extra $$$s per sale. But I wouldnt be happy if I purchased an option that really didnt do anything. So far, the things we have available have been thoroughly tested and are known to make a real difference in performance or application. All future additions will do the same thing. Along the lines of "updating" current drivers too... I will try to make most options retrofitable as well. Obviously if we produce a machining option, you cant add that to a preassembled driver, but as far as coils, spiders, and other palnned items, they will all be able to be used in current subs (provided that the "universal" option is selected or that the coils you have were gapped correctly or close enough for the newer coils). Im not designing new coils that are larger than the current "universal" gap. Really wouldnt see a benefit in doing so, and I also want to keep things swapable as well. Thanks... Scott

mrray13... no need to get pushy Email me your address and shirt size ([email protected]). I know you have contributed WAY more than what was required for a non-owner. Ill get a list from Nick and Shawn shortly of all of the people that have completed the task and have PMd or emailed them... then cross reference it what I have so far. For those that we do not have complete info on, we will try and contact or post their names on the forum so that they can get us an address and shirt size. I have 7 people so far that have sent me info and have been checked as "good to go". Ill get their shirts/stickers packed and shipped by Monday. Thanks and have a good weekend, Scott

Curt, Nope... the third company (OEM) I am referring to is another business I own and do OEM and consulting work for the HT market. Not an overseas supplier. But, the drivers will remain the exact same as I mentioned earlier for the HT guys. I will change things up and produce a similar driver but with a different basket and physically geared more towards mobile audio. Dont fear... the poly 6.5 as you know it will be around for quite some time. I am very fond of the design (I had a "little" say in it ) Thanks, Scott
-
I need to make an addendum to this post later today stating that when you complete the task (or feel you have and want us to check) please be sure to PM or email us with your account name, real name and address, along with your shirt size. We have received quite a few of them in emails with no info attached whatsoever... and its hard to try and match things up without it. We will be packing up and shipping out the first batch of them over this weekend. So to those that have already given full info and completed it, you should probably have a shirt in the mailbox next week Thanks, Scott

Is it an out of country order, or for something other than a Fi product? Not sure what your email is (no email name posted in profile). Simply send me an email to [email protected] and Ill get back to you later today. Thanks...

ngsm13... why thank you... I think I am no longer affiliated with DeStijl. I sold that at the beginning of 2006. Fi and Ascendant are two completely separate companies. Its a little complicated to say how things are set up (as legalities make it complicated to cover your butt under all circumstances). While there are actually 3 companies involved, there really is only one set of people building them. Completed Fi products stay where they are currently being made (albeit for only a couple hours before they are shipped out). Completed Ascendant products will move to separate building for warehousing and shipping. And the third company is for OEM and consulting work (so as not to burden either Fi or Ascendant legally with other OEM work). So for the most part, if you tried to contact any of the 3 companies, you would pretty much get me Fi will always be a direct only company. Ascendant will be a dealer based company with 1 online sales outlet. The other company you probably dont need to worry about unless you have a need for HT OEM work. Thanks, Scott

Takes a little trial and error as I have run across different "qualities" of MDF. Id try a small piece first to see how close you need to kerf cut things. Steve seemed to use wood glue, and Im sure that the modern "expanding" glues out there would work great. I used to put tape on the edges of the cuts and fill with resin before I bent things. Solidified them quite well. Box looks a little odd on the port section of things. Will there be dead space there as well? Can you MS Paint a quick side shot of how the port will look in the box? Thanks, Scott

Id offer my 2 cents but as soon as I saw "Astro"... Shawn is the only real authority on that one.

Congrats on the excellent score and showing to all of your team. We are just glad that we could help be a part of it. Thanks, Scott (oh and pics would be appreciated )
-
Short answer...Nope. The more time passes, the more I see the niche market that Fi is working its way into. I feel customers and the company is better suited cultivating that and only doing subs... and more options Ascendant will have all of the above... much of the work I have dont for Fi will transfer over to that. Seems to make more sense for a dealer based company that will move more products... to spend the $$$ on some nice tooling. We will get the original poly 6.5s rolling again, and then update them with a new tooled basket a few months after to integrate a grill and and be a little more car audio oriented with its sizing (HT guys dont fear... we will keep the original basket as a standard item as well) Ascendant, down the road a little, will have 2 component sets as well as some coaxes (market demands them). Thanks, Scott

I believe that pair of SSDs had shipped either on Monday or today. I will check when I get into the office tomorrow. If they did, them you stand a good chance of getting them in by the weekend. Thanks, Scott

its gone thanks, scotts phone

Thanks for the review. Im figuring you were the one I sent out the D1 copper proto coils to... as I did make one for a customer(and with my awful memory at this point, I couldnt tell you who it was if my life depended on it). I need to get them up on the web shortly as well since I was very happy with the results in testing (worked just like the original D2s). Thanks, Scott

Sealed sub box dimensions calc. and reduction help?!?!?
Fi Car Audio replied to Z1truth's topic in Fi Technical
Im getting red Xs for the pics right now, so I cant really check the enclosure sizing. But if its a trapezoid, with the top and bottoms being different sizes, but width and height being equal, then you simply do W X H X ((Top + Bottom)/2) in inches... then divide by 1728 to give you the volume in cuft. I absolutely love the box. That has to be the nicest drop in Ive ever seen... and like you said, he is doing quite a bit of business with those. At .7cuft per chamber, you are looking at .58 after displacement which will yield a .59 Qtc. Most people will find this too low for their tastes, although I tend to like .7 and lower Qtc sealed alignements. Very smooth and natural sounding. Shrinking things down to .33 cuft yields a .71 Qtc which is maximally flat. Like I mentioned before... most people like a higher Qtc .9-1 since it tends to emphasize/exxagerate things a little more. But at that point, you would really be choking the enclosure down. As ///M5 mentioned, drop them in as is and listen. You might find yourself liking them in the standard space (if you have a very solid midbass up front). Noting your initial impressions of them, then listening for a couple of days, see if you need things to "tighten" up some or not. If you do, you can shrink the enclosure up by adding either solid layers of MDF (which weighs a bit and Im figuring in that car you dont want to load it down), small empty MDF boxes (1/2" MDF is plenty for something like this). Large pieces of closed cell foam (syrofoam blocks would be fine and add minimal weight), or whatever you can stuff in their that is "solid" to take up space. You are in the opposite position from most people. Usually people are trying to stuff too large of a driver in too small of a space and dealing with a high Qtc. You can lower the Qtc some by using polyfill to stuff the enclosure and this maxes out at 1 lb per cuft and about a 15% increase in perceived enclsoure volume increase and the resulting Qtc change. If you have any other questions, let me know. Thanks, Scott
