    Alpine Type R box

    Seeking guidance on the box. This will be a 10" with about 800RMS. Due to space limitations, how would this work in a sealed box(.9')? I've heard that sealed is best and I've heard ported is best. What say you?

    Thanks,
    Scott.

    Re: Alpine Type R box

    For a Type R I'd definitely run it ported. I'd give a 10" about 1.5^3 tuned around 32-36. They're ok sealed but you're not going to see the output you would running it ported.

    Re: Alpine Type R box

    I've heard 2 in a Chevy Malibu sealed and dude was metering at 142 or something like that off 1K. For sealed in that car it was loud. Honestly best I've heard from Alpine.

    Re: Alpine Type R box

    This makes me curious...

    I've got two Alpine Type R 8's in my SRT4 Neon...

    They just don't seem that loud... they are in small 0.30ft^3 boxes. I believe they should probably be in ported boxes? Suggestions?

    Bigger box if you are going sealed. He had them in I believe 1^3 each.

    Re: Alpine Type R box

    142 ported is a lot easier to take in then sealed but i guess he must have done an excellent job of deadening and had one efficient as hell amp, would love to hear that setup.

    Re: Alpine Type R box

    i had a single type R ported that metered at 141 db playing music. won a bassrace with that sub. not many subs in that price range that are better than a type R. 2.2 @ 35 hz is what i had mine in.
