I trust they will.

What kinda vehicle is that? You said you face it forward, have you tried facing it towards the back? Allowing the sub/port to load off the rear truck/hatch can provide a little extra umph. Don't hurt to try.

For daily about 12 in^2 each "Port Area" or "Port Area Per Foot"? Couple more Questions: 1. Being that there's no pole vent, very little space needs to be left behind sub and thus allowing the build of a little shallower enclosure? 2. What's the displacement?

I'm in for 2. Payment sent. I'll cheers to that!

Porting difficulties, and thus the PR, is due to it only being a single 8"? Going with 2 or more should make porting a bit more manageable, right?

Wondering if it might be possible that I got the wrong gasket with my kit, assuming there are different gaskets besides the obvious being overall diameter. Are there different gaskets for different Fi subs?

I ordered a recone kit w/ basket for a Q. Wondering what all is included with this recone kit--push terminals, bolts for basket to motor, shim, CA glue, etc.? I'd like to have everything on hand when kit comes in.

FYI, it came with bolts/screws and terminals. Thanks FI

Thanks for info. Be nice to get fresh stuff for my recone.

Thanks for the info. I ordered glue from them. Starting with motor only. I have the terminals, just no bolts. Anybody know what size/specs bolts used on this sub?

I appreciate the info you guys have shared here. I resoldered the leads, mounted and "test drove". The Q enclosure also seems to have made quite an improvement. And for kicks, a video.

I came across this Fi on my local Craigslist. I've made arrangements to purchase it today from the seller. However, it's not a true Fi in the sense that its been pieced together, apparently with a different motor. I was told its a dual 2 ohm and here is what's used to describe this sub: Would have been nice if it were a complete Fi product, but it is what it is. Anybody recognize this creation and/or its components and does the description match the pictured sub's composition? Also, I'm open to facts/opinions about its performance in its current state. Thanks guys.

You're right, that somebody was me. So that braided sleeve there should be totally soldered along with the braided lead running in the sleeve?

I heard no distortion, what I heard was a loud pop/clank something of that nature. Took the sub out the box today and found this: Now I'm not 100% sure that was the problem, but looks pretty promising. It never made that "pop" sound in the old box so I'm thinking the dangling posts has a lot to do with it or perhaps the new box I made is just way out of tune. What I also noticed was the screws that I got with the sub/enclosure seemed to distort the surround after it was all cinched down. My thought was an unevenness with excursion. I've remounted it with different screws and all is well now. Hopefully no more pop. If there is still a "pop" what could that mean because I'm not putting to crazy a power to it--badly tuned enclosure? Lastly, the leads from the cone going to the terminal seem to be have a braided sleeve. Should that sleeve also be well soldered to terminal posts?

Are you saying that's probably what I heard instead of an actual "clip"? It made the noise on a very hard hitting, tight bass note from Nelly's "Where's the party at?" lol

I had some birch ply laying around so I built a box to the Q's cut sheet. I tried to putting it to the test last night and while I was running it at higher volume I heard a "clip" so I backed it down and ended the testing. It's apparent this Rockford amp isn't up to the task. Will fiddle more after an amp upgrade. This sub seems pretty capable though. In regards to testing the sub for parameters, there are two shops in town, one did not have the sub tester and the other wasn't open when they were clearly supposed to be--within normal biz hours. Wanna see if they have a sub tester on hand. Here's the enclosure uncarpeted. Beveled the edges of the port's walls.

Sup erribody! Hope to learn from some of the mastahz here.

I pulled the speaker out to examine some things to see how far different the enclosure from something Q would sit in and I found couple things. First is the total port length of this enclosure is nearly 10" shorter than that of a Q. Also while this box is an inch taller and deeper than Q cut sheet, the Q is roughly 6 inches wider. So this enclosure is smaller and port is shorter than Q I haven't quite figured out the volume differences but I'm certain it's quite different. I'm going to see if I can first look to scab in a piece to lengthen the port. If that totally sucks then I'll build a box to Q spec as long as the motor clears as it seems to be smaller in diameter but possibly longer so may sit to close to the rear running portion of the port.

Yeah seems like most the Fi cutsheets specify a tune to 32hz, so seems a little odd the recommendation, but this recommendation, I believe, is coming from the guy who had the sub built. I was told the original box(the specs given above) had great sound, but was not in the greatest shape aesthetically so the seller I bought off of tossed the box assuming the box was based off the MTX 95/1, but it really wasn't a MTX spec'd box that the Fi originally sat in.

Yes, exactly the info he got from his buddy--Neo motor for lighting storm. Here is what I was advised to shoot for in creating an enclosure:

I picked it up along with the Rockford amp and hooked them up. Apparently the box is not appropriate for this sub I'm told but I'm not all savvy with this stuff just yet so to me it puts out pretty well. More than I expected. But yes, I was told Neo motor. I don't think he'll be able to give me more info since he wasn't directly involved in the building of this sub. I got the amp and sub in the box for $300. Better than the poozookas I just replaced this with. By like solid 10x's. He said he had one box made based on the Q specs and it didn't sound right and so this current one is based off MTX 95/1(???)--too him still not right. Not too sure about all this terminology though. I think I need to research making a box for this.

Thanks guys!

What island? Big island here.

In searching for a new sub setup I came across an Fi sub and RF amp combo. Never heard of Fi so did a little search and found their site. On Fi's site is a link to this forum so that's how I got here.
