Ceiling space placement of an existing box

Moondog55 · 21st December 2010, 08:30 PM

In a short while we are removing one wall and making our lounge-room just a little bigger.

SWMBO has decided we need to downsize the stereo and she is tired of a big huge black box in the corner.

My WAF has run out.

I want to keep the bass so I am thinking of keeping the existing box and the 15inch Kicker EX that's in it and placing it in the roof cavity.
Here is the pertinent query.
Should I use it down-firing or use a plenum in front of it??

I would keep it vertical.

By plenum do you mean a kind of box to simply redirect the sound downward? If so that's what I would do. If you really mean plenum, I would not see the advantage of that, I think a simple deflector would suffice.

Yeah Cal; I just meant a redirection plenum, SWMBO is having second thoughts about all the subwoofers so a big infinite baffle is out.

Is there a preferred slope? Cos I was going to use the existing shallow roof angle for the biggest hole in the ceiling and fill it with a grill painted to match.

Sounds good to me.

What do all those letters mean>? I do not think I could get along with someone like that. A true infinite baffle can not been seen in the listening room. My girl joins me in my passion for good sound.

She Who Must Be Obeyed is member here and despite what i say we get along fine, it is just that great big woofers and small rooms need compromise.
We both love real bass but we need to have room for the grandchildren ( rug rats )

I wonder how many glasses of wine it took to get her to pose for that one?

My god, that drill has a cord on it!
