Don't know to be honest,
just don't want mine to be a defective sub.
I'll check mine tomorrow for ya
Can you post a youtube vid of it making the noise?

Sounds just like mine,
if you face the cone of the driver at you it sounds clean, might be just how they sound in free air - and be completely fine in an enclosure.
Have you got a 15" ready enclosure to try that theory out?
Playing bass music with it running overpowers the vibration noise, in fact it's only audible below around 30Hz.
Mine both sound identical, even tried each voice coil individually.
I'll continue with the project but will drop an email to Parts express just incase they've had any other complaints.
ive got a ported enclosure which currently houses my JL driver - will whip it out over weekend and refit the t nuts - as they slightly differ from driver to driver spacing and try it out.
ive commented on partsexpress.com youtube video where they show the Ultimax - they've replied and they say i can contact their technical advisers for trouble shooting.
Just sent that email myself.
Got this reply
"Richard,
I cannot tell from the video, the mic is distorted the whole time. What I could hear was typical mechanical noise which is common with any free-air subwoofer like this, especially when playing sign waves through it at high-ish excursions.
Sincerely,
Matt

There's no distorting on my recording though, that's the actual sound it was making.
Did you send then your video link?
the guy who i spoke to over youtube said he was going to send them my video....
haven't got us mixed up have they?
will see how this sounds tomorrow - with just 2-3mm excursion miss's txd me from upstairs to shut it up lol

Just out of interest I looked on YT

Earthquake DBXI-15 Unboxing - Comparison with DBXI-12 & Free AIr - YouTube
Did the fan upgrade today in the EP2500.
Soldered the 12v fixed regulator and covered with a couple of coats of liquid tape to insulate:
Have you got a link to that liquid tape?
