I've had a single vxf 15 for a while now on low power and did amazing on a cheap planet audio amp. Been working towards a full skar system and now I'm officially all skar. Ordered a 2nd and 2 sk2500s to power them in my new wall setup.
I got 2 of the VFX-15's to replaced the 2, SDR-15's that i purchase early. The SDR sounded great but it could not keep-up with my Sinbosen K-1200 amp. When i installed them in the SK1X15V sub box from Skar the VFX-15's started pounding my home theater vibrating everything in the room. The VFX-15's are a good match with the Sinbosen K-1200 amplifier.
Built them a custom sealed box & I was just doing it before building a ported box to see the sound difference, but it's so fn loud & has such good SQ, i don't even want too!
Got them in the back of an explorer so I had to strap them down where they didnt come up & kill me. That's a lot of weight.
Not pretty but I'll mess with that later.
I had a 10w3 on a fsgate amp & wasn't happy. Put this in & that L dont even sound like it would suffice as a midbass speaker.
Good quality stuff.
I've been running a base model skar audio 12 dvc 2ohm and its great, upgraded to this monster of a woofer im running a skar mono 1200d amp wired this sub to 1 ohm and man this thing slams. I have it in an f250 I get alot of looks wondering where the crazy bass is coming from. I recommend skar audio to everyone I know they make a great product and very well built. If im crazy enough to go to a bigger build they are my go to.
