Benefits of going to a sealed 12"?

[GhettoSQ]

A few years ago I built a wacky clamshell isobaric design with a pair of 8" SEAS woofers I had lying around. It's a fairly big box with a 4" wide port, qualifying as, I guess, something close to an extended bass shelf design. Small room, mated to some 8" Paradigm 2-ways, and it sounds pretty good for music and home theater, though perhaps suffers a bit from one-note bass syndrome. Besides cosmetics, is there any musical benefit to building a new box around a Dayton 12" classic? Would I lose something in home theater performance? would I notice a big improvement in depth, attack, etc.? I like the Dayton classic 12" as it models well in a reasonably-sized sealed box and doesn't cost too much.

Dayton Classic, short Xmax, cheap as ....
I doubt its up to the quality of your Seas
or do you mean Dayton Audio Classic Subwoofer

Try tuning your port lower first - if your cabinet is large and you've not dropped the tuning far enough, you will end up with a peaky response.

You can either extend the port's length, or reduce some of its cross-sectional area. Some trial and error may be required.

Hi GhettoSQ,

Try a vented (BR) box with 100 L_net, and a 4"I.D. duct @ 16" long. Then you can play with changing duct length, and stuffing the duct.
