That's a zv4 rev 1 with the OG mega roll surround. Get with DTX ( Directronix) for an up to date recone with mega roll V2. That sub uses a true D2 8 layer coil. I believe there is a high BL coil available as well but those coils are very similar if I'm not mistaken. That's a potent driver with the right soft parts.

That's a zv4

That took a turn fast...

Took you as more of a Chevy guy haha. Nice ass truck Meade. Nice truck indeed.

2x punch 40's in 1996 powering 4 punch dvc 10's.

Deaf Bonce and SMD go good together.

Deaf Bonce is amazing equipment, team and customer service. Big ups to Deaf Bonce!!!

Where did you get the empty full throttle case?

Level 5 would be the one.

Holey baffles Batman!! Lol. Nice

You'll widen your bandwidth but you'll need a lot of power. I'd say a 6k @.5 or two 4.k's @1ohm minimal. Invert subs also or you chance cooling issues. They'll sound great. Do it to it dog.

6 kicker 15's on a big purple US amps surfboard in 1996 (Junior high school year) in a c-pillar wall in a new suburban.... First tap out was 8 kicker solo X's in an astro van at ces 2018 in Vegas on either 8 or 16 kicker 2400's in a 4th order. Wasn't ready for rebassed Bon Jovi!! Been hooked since.

You can always shrink it down if you don't like the outcome or output. Give it a shot..I bet you nail it.

70-80in² would work just fine. Port won't be long either due to higher tuning. Some people like to play with stackable ports to dial it in which is a good idea. This will be pretty straight forward. Not hard to build either. Even a bigger Port area on 4th orders is ok. Maybe... 90+in or so

See what I mean by bigger ratio is peakier? That's a 2.5:1 ratio. If you go 2:1.0 ratio it'd be less peaky. You'll get lows with the fourth without a doubt. The orange plotted enclosure is dead nuts and I wouldn't build a box tuned any less than 31hz. You just simply don't have to with zv5 subs. They play Lows tuned at 32 and 33 Hz no problem. the upper range of the 4th order is the whole point of building a 4th order. You'll be loud and play low. A lot lower than that graph is showing. That's just a general idea and other factors come into play. For the most part tho that is a pretty good indicator of your enclosure peak. You get the Lows from the sealed side so as long as you have sufficient power they will be there.
