How did you tear it? Is it separated from the cone?

Almost looks like a chaos with Fi parts

what kind of amp? electrical? Voltage monitoring?

You shouldn't go by BTL cut sheets..

The box I built for a HTQS pre-09 SSD 12" was 1 cu. ft. so definitely go larger.

150 shipped. bump!

I think sonic is trying to get rid of their old stock type Rs for 100 a pop

get your sp4 set up correct. this time around.

its worth a try. You can build a sealed box in a flash

You should be able to big 3, good wire, and batteries to maintain. You really don't want to go cheap on an alt.

The box Fi provides cut sheets for is 1.25 cubes. I would do that. You should have a noticeable difference with a larger sealed box. even if its less than .5 cubes

1 cu. ft is what they recommend for the SSD. For the Q, you will need about 1.5-1.8

I normally like to hear my music.

The term lab is the worst thing that ever happened to car audio

No problem. Sounds like you're ready to get crazy. Thumbs up!

16 should be good. A little bigger wouldn't hurt. I would shoot for 4-4.3 cu each. I would say about 14-18 sq inches of port per cu foot.

so you're @ 13 cubes with 3 woofers? What are you wired to now?

I agree. People could have been more helpful here..

I have 2 Q drivers I'll be saving for a summer bump down.

Finally got my hands back on some straight street jam material. AKA: Qs and a BTL UFO I've seen some UFO BTLs have a spacer in between basket and the motor. Is this just an adapter for basket patterns or is it a beneficial option to the sub? Excited for my new Fi experience and so is the wife =]

I still am seeing spacers on these. I ordered a recone with HiXmcoil, so I think I will need one to prevent the coil from slamming the raised motor lip.

That motor structure looks crazy.

No. High Qts only makes the coil gap a bit larger to take away some motor force away from the driver and helps with maintaining its linearity at high excursion levels. A sub without the HQTS option will still perform well in reasonable volumes of a sealed enclosure with good output.

Got the motor in and its in really good condition. Ready to recone. With the longer coil would I need a spacer or use washers? anyone?
