Old wall. Not the greatest pics, but basically 4 15's. Geometry of the Explorer had port area way limited. Was doing 157-158 neighborhood

Also box had a really funky shelf at the back. The has been tightened up so we don't have a little turbulence chamber at the back of the enclosure

Orion HCCA's handle 6K according to their marketing. They didn't fare so well VS. 4K each.

you should send those pics and story to Orion... But I guess they already know and don't care that the hcca's are all hype



nice numbers with 4 15's btw

Took some effort, but we got the old baffle out. Now the interior is getting a lot of bondo and sanding, and eventually paint and possibly resin. Trying to get all the edges rounded over nice, fill all the old screw holes, and smooth it out perfect before I put the baffle on.

Also, one of the RF 4000's self destructed, so we're down to 3 amps. Built up 6 Shocker Sig 12's for him. This will keep the cone area of the 15's but allow much more port area.

Dual 2.8 Aluminum coils should also allow some other power options. We are going to start with running each amp at .7 nominal (1 amp per pair of subs) and see what happens. If we're rising terribly, we're going to look at different amp options and we have some good impedence options with so many coils.

Yes. Hopefully we have it ready for Sanford.

Put up the roundover on the port side, filled it with spray foam, and put up another can and a half of bondo. It'll need a few more cans of bondo, a lot of sanding, then possibly paint with resin, but Mike will do that if he wants it done. I won't do that one cheap and I know his Expedition needs a bunch of work.

We are quite limited since the top, bottom and sides are already there and I'm not trying to remove them. Best we can do is round, smooth, and put up a new baffle. It'll be solid, subs will be flush mounted. It should give a good boost in port area and hopefully tune high enough that we can actually lengthen the port to tune DOWN to desired frequency, though I doubt it. More likely we will still want to tune higher, but it won't happen so at some point we'll have to just add more power.

we did that on the nspl crx. tuned in the 70s brought it down from there.

No way to get adequate port area and tune that high. Even if we used only 3/4" baffle and a 24" wide port loading down the wall still makes port 12" deep

Cool build. Serious question. How much of an issue is reflection off the back wall coming back through the cone? All of that wall thickness is great for rigidity. But cones have little to no transmission loss. I expect that you'd see cancellation for frequencies who's 1/4 wavelength is the distance from cone to rear wall. Do you observe this?

It is rather shallow, and up til recently it was tuned quite low with an awkward "shelf" in the back. Really I could angle the back wall, but it would eat a good bit into volume that I'd rather not spare. May be something to consider if there seems to be a problem. When you figure the 10" motor though I doubt much wave will actually hit the cone.

Got the baffle glued and screwed up today. Seems quite solid. My friend is coming down with the amps and subs tomorrow and we will be mounting and wiring everything and possibly be doing some testing

It's been a pain in the arse really. There's a lot of cosmetic stuff yet to do, plus some testing and perhaps playing with tuning (port length). Otherwise, just mounting all the gear is about all we're going to do this year. Weather is getting cold and I'm ready to head to Florida, and my friend is about tapped on funds with some repairs on his other cars all happening at once.

After we finish the box and tuning we'll pull an impedance sweep and consider different wiring options or possibly different amp options depending on where we can get impedance to sit at peak.

I wonder... If I will ever get that far into audio..

Right now, I have my SA-12s as any rookie would, don't know my peak, don't know what's ideal to tune at. No TL, no gear, nobody local to show me anything.

I like that amp rack. I really like when people take the time to build a rack and showcase the amps. It's an artform of sorts. It bothers me when people take all that time on a nice box and then just throw their amps in there. That will be real easy to cool if those amps end up getting hot too; just add 2 fans for each level in a push/pull configuration.

I can't take credit for that, but it is quite functional. This is a fart-box only, heating is not an issue since amps only need to run 3 seconds at a go.

Like the windows on a liquor store in the hood.
