Need some suggestions for custom Dayton powered sub build

[bizzy07 10+ year member]

I have experience with building boxes for cars but not much for houses. I have no idea how much space to give the sub or what to tune it to so any help or suggestions would be much appreciated.

Equipment:

15" Dayton Audio Reference HO RSS390HO-4

500 watt Dayton plate amp

2 4" Precision aero ports 15.5" max length each

I will be building this out of 3/4" MDF (already have 2 half sheets). The sub is only going to be used for listening to music (mostly rap). The room is 12' wide 20' long 8' high with cement floor and drywall walls.

Just bought another sub, amp, and set of ports! Some input would be awesome!

Wow, no replies. This has to be a first. I don't have time to model this for you, but if you just call PE they will give you the size and tuning you need. I'll keep and eye on this thread if you have any questions about what they say. Also don't forget to brace the box.

Ended up going 3.5ft^3 at 30hz. I tuned it high because it is only for music use. It does much better than I thought it would. Now I just need to build the second one!

That is 3.5 net after sub, amp, port, and window style bracing. I should have got some build pics... I will try to remember to on the next one!

Looks sweet! Is like to see some build pics of the next one. I would also like to hear if you notice a difference with running two vs. one. Not Spl, but in the sound.

That looks great! Curious to how it performs. Planning on doing one of these soon....

can you post the design/cut sheet please? I just picked up a 12" Acoustic Elegance C12.2, think this enclosure would fit that nicely for my setup.

The box is 30"Hx18"Wx22.75"D. 2 4" ports 15.5" long. The box has one "window" style brace right below the sub and a double baffle. The double baffle might not be necessary but I wanted to flush mount the sub.
