Help me build a Home Theater subwoofer

[rocko1290]

I’m here to get some help building a home audio sub.

By recommendation, my original plan was to have:

--350 liter enclosure
--Dayton 15” DVC Driver
--Rhythmik Audio 250w plate amp (rumble filter @ 17 Hz)
--8” x 29.5” port (17.8 Hz tune)

Well I decided that a 350l enclosure was just too darn big. So here’s what I can do:

My budget is about $360. The sub will be going in a room that is about 300-400 sq. ft. I want to do a 200 liter ported enclosure. I will use the sub for movies/games/music.

I would like to get a Rhythmik Audio amp, because they can install the rumble filter for you and I don’t know how to do it, nor do I have the equipment. They make a (250w @ 4 ohm) amp and a (350w @ 4ohm) amp. I could go with either one of those. I will use any 15” driver that you think will work best with a 200L enclosure and a 250 or 350w amp. www.partsexpress.com is where I planned on getting most of my stuff from.

Once I get the amp and driver decided on, then we can talk about the port/box tuning frequency.

I appreciate any help.

--Thanks

P.S: How will this new design compare to my original 350l design?

Save up the extra and go for the Rythmik Directservo kit, I've just finished one and it's

It goes flat well under 20Hz in my room in a 55L sealed box

They're on sale at $429 at the moment

Thanks for the suggestion, that's not what I'm looking to do though.

That would do the trick with your planned enclosure And you don't even have to vent it if you don't want (if it were me, I would just go sealed).

Enjoy!
