    Re: 3 type-R's box size

    all one box, no dividers, just support.. say around... 2.25 cubic feet.

    Type R's peform better in a ported enclosure btw. I had my two R's in a sealed enclosure and it ******. Ported, totally different story

    i would almost bet you would get better results with 1 or 2 ported vs the 3 sealed.

    Re: 3 type-R's box size

    definitly do a chambered setup....if a sub dies by the off chance your other 2 wont have to run off the extra volume, add to that the the dividers act as bracing themselves....but I would go with 2 ported instead of 3 sealed....Isnt it going to be a wierd ohm impedance? Size-wise, shoot for 3ish...alpine recommends 1ft^3 max per sub and oversizing it will help bring out the lows better.

    PM PV Audio...very professional and very knowledgable. He'll give you everything from wood dimensions, to a 3D model. He took time with me to explain why such-and-such is better...just send him a PM and dont think twice.

    an odd ohm impendance matters why??????? Who ever said it had to be an even number?

    Re: 3 type-R's box size

    What if he got all D2's? I'm not saying it matters but If he's got an amp thats not 1ohm stable its something to to consider...if he's got 3 d4's then he's alright.

    Edit: Should have done the math before I posted...your right tance, even if it's D2 he's only sitting at 1.3ish...my mistake
