Hey all, new to forums. Nice place, glad I found it.

My question is, what would be the best enclosure for a 15" Alpine Type-R? I want to reverse mount it to show off the perdy magnet structure :cool: I think I can figure out specs, haven't built many boxes, but was wondering if there was a premade enclosure out there to base my build off of? I want to run it in the 30hz-35hz range for good, clean, low SQ. Any info, tips, or leads would be great.

I haven't purchased my low end yet, still deciding on what I want and if I can actually build/buy a good enclosure local for the reverse mounted 15" I wanted it more mounted up/down vs front/back, maybe with a slight angle towards the back of the car.

My equipment consists of ...

HU: Alpine 7998
High Amp: MRV-F345
High Stage: Type-R Coaxials (front/rear)
Low Amp: MRD-M1005 or MRD-M605 (haven't decided yet)
Low Stage: Type-R 15" 4+4=2ohm
Capacitor: Alumapro 5f C.A.P. (haven't decided yet)

I know my highs are lacking, but should be decent, I'm driving a small hatchback. 96 Probe GT. Like I said earlier, my main concern is SQ, and I know I'm new so some might just blow me off. I've been into car audio for 12+ years and love it, and love doing it right. I don't take shortcuts and would rather not install my equipment if it can't be installed correctly. I know since I am so new some might blow off my quiry, but any help from the caraudio Gurus would be great. I hope to be a long time member, make some friends, do some business, and enjoy the raw wattage rushing through my car just like you all again. My previous setup is below in my cardomain link.

thx for reading my essay, take care all and /salute!

heres a box calculator. As far as i know, its fairly accurate. It gives you a cut sheet to build the box by.

I have used this on my last to builds and it works great and the boxes always turn out nice.

hope this helps....

type r's usually dont like to be sealed....

I suggest you build a nice ported box

Go ported if you're able to. I highly suggest it with this sub. Save your money and don't buy a cap.

unless your goal was to have the sub sound like ***, i wouldnt seal it

but hey, maybe you like ****** SQ!

but seriously. Type-R's and sealed enclosures dont get along too well. port that thing!

Although they sound like **** either way you install them:laugh: I'm considering them for my next spl setup.

Thanks, I've had 2 Type-R 12"s ported, thought I would try sealed, but guess I'm staying away from sealed, lol.

sealed just dont have a nice response curve compared to ported.

Always had ported, never sealed before, after some more reading I don't think I'll ever go sealed.

A sealed enclosure isn't all bad..... it's just the worst way to go with your type R
