Diamond Audio CM310D4 enclosure size conflict?

[e zee]

First off, this is my first post on here, lots of good info on this site, but I have a couple questions. Sorry if these are newb questions, I've searched google for the last few days and haven't been able to get the answers I was looking for.

I am familiar with building enclosures, I have built several before, but this is my full ground up design for maximum quality and output by myself.

According to the official spec sheet for the Diamond Audio CM310D4, the reccomended vented enclosure volume is 0.75 cu ft. I plugged the parameters into WinISD Pro, and get an optimal vented enclosure volume of over 1.5 cu ft.

I looked through the thread with various enlosures with different volume and frequencies, but none that were as high as reccomended... 58-52Hz.

My setup:

2 - Diamond Audio CM310D4

1 - Diamond Audio D31000.1

Also, would you reccomend running 1000w@1ohm, or 400w@4ohm?

Thanks in advance.

lol go ahead and tune at 50+ hz.

Youll want to be around 30-35 hz.

1000w at 1 ohm, set your gains correctly.

should I stick with manuf. volume? or WinISD?

If I was you I'd go down the middle of the road...... I'd build an enclosure in the 1.25cuft. per sub range, port tuned to the 30-35hz range..... there's no sense at all in tuning the port to 50-52hz, that almost has to be a typographical error....

That enclosure size at that tuning should yeild great results for those subs...

Thanks, turns out Diamond Audio has full designs for recomended enclosures, I'm going to try that first, and if I'm not happy with it, I'll do my own.
