I was looking at sub kits and it seems they're all sealed. Are there any ported sub kits or ported flat packs available?

Pretty funny.

The problem with drilling a hole is the driver hole is in the middle of the baffle so there wouldn't be much room for a round port.

I forgot to mention this is for HT. Not for a car.

There's a 4cuft ported 12" model being cut right now. 15" model gets done a couple weeks later.

Great. Are you going to pre-cut the port hole or are just off centering the driver hole?
If you're pre cutting, how big is the opening?

Personally, I would like to see an 18" option and maybe a bigger box. 5 ft^3 or larger. I'm sure others would as well.

Yes, they will have precut holes for the woofers and port tubes. The 12" model will fit the Dayton Ultimax and RS series. They should be perfect for a ported 4 cuft box.

The ones after that are going to be big. The box will be designed for dual opposed 18's or 15's and also for a ported 15" woofer. Likely the 15" Ultimax and RS series again.

It's going to be expensive to get a decent number cut, so I'm not sure how many of those larger boxes will be done at first.

Note that ported box designs require precise port and volume dimensions with tighter variances, unlike sealed subwoofers. If the port dimensions or volume of the cabinet are not within specs, the sub output and sound will be greatly affected. Users should check the requirments through a TS calculator to get the correct parameters for a given volume.

If it's not a BIG screen, it's not a theater...

That will all be figured out for the woofers in the kit.

But the boxes are longer so you could extend the ports and tune them lower if you wanted.

Eric, not sure whose modeling designs for you, but that UM12 does not look very good in 4 ft3 vented...

The model will fit the 12" Ultimax or the 12" Reference Series. They both use the same cut out. I'm sure there are other woofers that will work okay in the box as well.

The PE site says the 12" Ultimax should be put in a 4cuft ported box or a 2 cuft sealed box. That's what I was going by. I have yet to actually test one out, but I will soon.

Not sure what Dayton is thinking with that one, Qts is way to high for a reasonably sized ported box




The 15 has a similar issue, but not as bad as the 12. These woofers are optimized for sealed boxes.

Erich H. Look forward to your 15" ported flat pack. I'm assuming you will build the 15 ultimax to parts express specs as well?

Their 6ft3 rec isn't as bad as the 12, it could still be better. 7 ft3 16hz tune looks pretty good with the 15".

I would assume Eric is looking for moderately sized enclosures, so just leaving the UMs out might be better.
