Hi all,
So am in (hopefully) the final stages of designing my first enclosure, I decided to go for the Dayton Audio RSS315HF-4 12" driver. Using WiniSD I have worked out that the internal volume will be 3.7ft^3 tuned to 24Hz.
I just wanted to post the plans on here before sending them off to get the wood cut to make sure that it all looks ok, I also have a few questions.
Firstly, does the bracing look strong enough? was just going to have that one central panel but could add in a second one if needed.
Secondly, is a crossover needed if it will just be on its own amplifier channel (which has DSP) and if so will this need to be a band pass filter? I have struggled to find information on what values of capacitors/inductors I would need to use. If anyone could point me in the right direction that would be amazing.
Sorry for the hand drawings do not have access to design software. are there any free softwares that are good for 2D design? would be helpful to draw out the individual parts on there for accuracy.
I think I've attached all relevant graphs.
Any other tips are very welcome, thanks in advance
P.S. am aware that this driver is better in a sealed enclosure but ported suits me better for what ill be using it for.

Personally I prefer to use dowel (rod) strategically placed, by ear, it can be moved around if tight fitting, and when the good places are found PVA'd into place. It is easier than cutting your obolid shapes, and multiple pieces can be used with a minimal loss of volume. You could consider corner bracing with Scotia, but that is labour intensive.
Cross-braces are more effective (consider in your design how to brace each panel against the one on the opposite side of the box).
I cannot work out what that horizontal in your second picture is, or is meant to do.
Front to back dowels are effective where the cabinet is most likely to flex, ie in the middle near the woofer cut-out.
Just 'suck it and see' using knuckle rap and the ear to determine deadness.

When it comes to subwoofers, the cabinet is going to try to inflate like a balloon. Place braces accordingly.

Also how does it work with having a speaker terminal? surely cutting out wood and replacing with thin plastic will cause issues on the back panel?
The cut out will surely be very small in comparison with the large area of the panel, and you can place it where it is less problematic as in at the bottom away from drivers.
