Did it ever bottom out in this video? Looks like a looot of excursion. I just got my ZVXv2 15”. Wired to 1 ohm, with SK1500 1500rms 3000max, tbh I haven’t been using a meter to see how many watts I’m pushing but it’s about 3/4 of the gain. I thought it was moving way too much on low notes but this vid proves me wrong. One issue tho is my box jumping. That was a HEAVY ASS BOX. I have no idea how it’s jumping. Might just rachit strap it down.
Sealed 15s and 18s hit deep and low, shake harder than ported. They might not hit a couple of the lowest notes very loud, but like 95% of the low notes it does hit well. sealed shakes your body harder. Im pretty sure those woofers moving harder also shakes everything and thats the base. Ported base is louder but empty somehow. Sometimes it can hit the lowest note louder. Its a very small trade off. Big box sealed still hits low.
