sliding glass patio door ..

[just-some-guy]

i have the typical sliding glass patio doors about 4-3' directly behind my couch. system is on the opposite wall.
how does this effect bass/sub bass ? i read in a mag many years ago, that sub bass goes right through it. that would mean my room is LARGE.
watcha think ? tia

I would hope you actually have curtains or some thing closed over it. I don't think any of us want to see you.

I think you should get a curtain or something to cover the window, but if the bass goes through it. That would be a good thing IMO. Means you don't get the back wall reflections. I think the main concern with a sub. Is your distance from it. If the sub is your end table. Then it won't matter how big your room is in many cases. However if it sits in the corner size becomes an issue. This is why I suggest dual subs and in some cases4 subs. Doing this eliminates a lot of issues and allows you to enjoy the thundering bass.

In Audioholics Testing the best response in a room was found to be with both subs center on the side walls http://www.audioholics.com/tweaks/get-good-bass/subwoofer-placement-the-place-for-bass-part-1/subwoofer-placement-the-place-for-bass-part-1-page-7.

yeah. i have vertical blinds. but for bass, those mean nothing.

i am now hunting my diy dual sub solution.

The door is behaving like a bass trap.

Mind you that those results are only a start, but only really applicable to that room. It's a good starting point, no question, but there are too many acoustic variables to say with certainty that such an arrangement will provide the best bass.

thats pretty much what i was thinking.

the only way i could place my subs to the sides, would be to stagger them. left side would be even with my seating, and right wall would be about 4' forward of seating.

If you want to make sure then play some music with the door closed then open. If the bass changes (or mids and highs) then the door is effecting. Yes bass does go through windows easier then say drywall, but you still might get some low end nulls and peaks coming from it. If you do notice a change with it closed then I would recommend thick absorbers on the stands in front of it.
