Default First diy build

Hello all. New to the forum. New to all aspects of diy speaker anything. I have had my Marantz 2270 since I was 16 and never wanted for more. I want more! I would like to do a sub build but after about 2 weeks of intense reading I know one thing, I don't know what the hell to do.
Looking at the Dayton RSS390HF-4 with a 500 watt plate amp. It will be going into a 18x14 room, subfloor, plaster walls. Mostly for music about 80/20. Would like to do a ported box, I think. Any help and I would be greatfull.


Fresh One!!
MF

IIRC, the -HF versions want considerably larger boxes than the -HO versions.

Have a play around in WinISD and see what does what, and think about what size cabinet you can live with.

Don't rule out sealed, those subs do very well in small cabinets. Might be a good starting point for a first build.

As Chris says, how much space can you take up? This will be a good starting point!

I would love to play with sub programs but no computer. Never had a need for one outside of work I guess. I have played with the online versions but they all seem to say something different. A sealed sub would be fine as well. It can be as big as it needs to be no restraints there. I have a woodworking backgroud and all tools that may be required.


Thanks
MF

No pc?
If you want to noodle, ask the local library to get a copy of Loudspeaker design cookbook by Vance Dickason.
Should be on v. XXXXIV or something now!

With a calculator a paper and pen you could design almost any box you can imagine.

Please be gentle. After looking at what build data and what ever calculated data I can find. No PC so no real sims. This is what I can up with. Is port top or bottom better?
New drive from above dcs385-4. Also on drawing I labeled driver as dsc, dislexia kicking in.

The cabinet sure looks big enough, but I'm getting a crick in my neck trying to read the driver specifications!

EDIT: It's alright, I've looked them up on Parts Express! May get my David Weems book and calculator out!

To be clear, we are now looking at a Dayton dcs385-4 15" subwoofer.
