wait, are you going to use the 18" PRs or 15" PRs?
Matt

18". They have a 16.75" cutout diameter.

Cutout diameter is the hole you have to cut to fit it in the box. Always smaller than the rated size on any sub. Overall diameter is 18.5" with gasket.

Yeah my 15's are like 14.125. But those 18's should fit in there with some cutting of one of my upper top baffle. Not a whole lot though.

Ya know, with as popular as they are in home theater, I'm surprised I don't see more. I know they cost more, but everyone is always trying to save space, sooooooo...

What you plannin bro?

So, talking with PSI now about the PRs. It's lookin like he will take care of me for a decent price
Anyway, here's what I sketched up for the box changes. Unfortunately, @Buck is not in the best of health, so he's not available at the moment. Hope he's doing well. In his absence, I gave it a try. Only sketched what I would change.

Original:

Changes:

These things will JUST fit.

Well just paid for my PSI passive radiators. Was kinda just a thought before, but I'm committed now. A pair of 18" PR's, upgraded high-roll surround for 3.5" p-p, dual spiders to handle the power, carbon fiber dustcap, built and shipped in a week, for $350. I'm happy with it as of now. We'll see if I feel that way when I get them //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Just want to say PSI has the fastest turnaround ever. Paid for my passive radiators Tuesday afternoon, and just received tracking info. They weren't standard either, got a couple upgrades.

Interested to see how this turns out...

Got the box design done:

And just got my PRs in too:

Might not post a whole lot in this thread anymore, I'll be starting a build log soon. I will direct to that though, and I'll try to come back and update this when I finally get these in and start tuning. Gonna be a while though, still have all my electrical to buy and cash is tight right now //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
