want to build dayton dvc385-88 15" dvc sub. P.E # 295-190

Hello to all, as you can tell another newbie asking the same old questions. hopefully you can be of some help. i have been reading this forum for a couple of weeks now and i have got the diy fever. my only diy exp. is taking speakers from one box and making my own....well on to my post. i want to purchase the mentioned sub and build a passive sub out of it. i have bassbox pro 6 but not getting the results that i like on box size. would like a basic cube sealed. if this project works out i would like to move on to a mtm tower using dayton speakers. well again any suggestions on box demensions would be great.
thanks to all

I don't have any software on this computer, maybe someone else will get around to it before I get home.

As far as your MTM tower, there are a couple of designs here that should meet your needs well - based on RS drivers.

have bassbox pro 6 but not getting the results that i like on box size. would like a basic cube sealed.

That driver has a pretty high Vas, so it's not going to model well in a small cube.

Yep, for a Q of 0.5, I get that it takes roughly an 11 cubic foot box. Yikes.

Is that the Q he was shooting for?

I modeled one in about 110 liters for a .7Qtc. Walls lined, minimal leakage.

Not specified, and yes, a reasonable volume can be had with a higher Q box.

thank you all for responding, i have been playing with bass box pro 6 and using a sealed cube design with normal fill i get a qtc of .9 and a box with 4.9 cft. does this sound right or am i way off...someone else made a box the size of a end table and this would appeal to me?. I do have an old madisound 12"dvc dual 4 ohm that i could use i could post the numbers saturday as it is stored away.

There's something wrong with your model. The original Adire Tempest has very similar T/S parameters to the DVC 15.

You can pretty much copy any of the designs in the link below.

Most of the time people don't want a "Q" higher than 0.707

I have mine in a 3.5 ft3 sealed enclosure and it works well for music but is only marginal for HT. When time allows I plan on building a 7.5 ft3 ported cabinet.

thanks dawaro, i would mainly want to use mine as ht...like 80%-20%...i guess i'll start with 8 cubic foot box and work my way down. i like the sealed sound better than ported....my subs now are carver 5.1 10" powered in the bedroom and downstairs i have a madisound 12 in a 2 cubic ft box that i had built (ouch in this forum) its sealed and sounds great but i want a 15.......for my movies
