Received my second 15 today. Similar issues, misaligned motor, excess glue all over the motor.

I'd stay away from FI until further notice.

I remember back in the day you’d always see those stickers on competition vehicles of a little boy pissing on fi lol

They are 1 of 2 companies that build IB specific subs and other than these "cosmetic"issues, they seem to working really well. We will see if they still work in a month.

Hard to see in pic but right side of motors are a few mm weird. Top pic shows no holes anywhere.

It’s looking like those little stickers may get popular again ...

I don't think those motors slightly off is an issue and this is something I've seen on all kinds of subs from many different manufacturers for a long time. Now gluing the cone on without lining up the screw holes is such a rookie mistake that's very worrying, and letting that go out the door at the prices they charge is shameful.

Any coil rub when you push on the suspension?

Nope

Nope

At least that’s good ..so the coil alignment must be right

On a good note though. Shes mean and power hungry.

So i've been playing with Winisd. All graphs are modeled in 200Cuft on 1 sub. If you model smaller, you get less excursion. Fi states its a 34mm One Way excursion, with xmax at 20hz on 600 watts. So i thought id model it.

As you can see. At 600rms. Fi is spot on(for once). You don't need any kind of SSF and it will play all the way down to single digits with no issues. VVV

So i wanted to see what else i can do. Below is on 1000 watts for one sub. Obviously excursion goes way past acceptable. VVV

But as soon as you put on a 13hz HPF with a 24db filter on it. Its under control VVV

Below is 1500watts on 1 sub with a 18hz 24db HPF.

And I can play with this all day and get that rms rating higher and higher with a higher HPF every time. Its got a 3in VC so honestly. I'm not sure just how much i can push these things before thermal rating but i think its time for a more powerful amp than the 1k im throwing on 2 of them. :3
