Opinions?

The bass from my HT is better in everyother room, but the room the subs are in. I listen to music 2 rooms away. :(

That is way too much of a generalization. There are too many factors that can affect this sort of thing, especially the room dimensions and the location of the sub. Almost every room is different.

True, I've only experimented with 6 rooms with middle openings, and a dozen or so with corner openings.

My HT room has no real good place. ARGH! Just a least crappy one.

And the local HT store agrees.

Is there anyway you could add ,...say,...French doors to the opening, that you could close when listening and leave open otherwise?

Have you tried a nearfield location?

Yes, because an opening doesn't reflect bass. It's well known that bass traps work best in corners, and an opening is similar to having a bass trap there. Of course, what's beyond the opening is also a factor. But "science" confirms your observation. :D

Thanks. I just knew it wasn't a fluke.

It is in a nearfield position. From what I hear (read) that's where SVS' seem to shine.

Part of the countertop from my kitchen is in front of the opening, so french doors would look really odd there. I don't plan on living here long enough to warrant enclosing the room and installing a single door.

1. Not true

2. True

Calibration is everything ;)

It is calibrated. Still a very problematic room, no matter what subs are in it.

I have this problem too. Opening is in the middle of the wall to the kitchen. If I place the sub in the nearfield corner I have a HORRIBLE dip at 40hz.

If I place it in the corner behind the TV my response flattens out nicely with only a dip at 70hz....

What really sucks is my living room is only the temp home for everything since I'm hoping to get a start on redoing the basement sometime in the near future and then moving the theater down to its rightful home...

You may be very disappointed when you move your HT to the basement. With a capable subwoofer on a "suspended" floor such as a first-floor-over-basement, you get tremendous coupling of the sub to the floor. This provides tactile vibration of the floor. I have two friends with similar arrangements and the tactile nature of the bass in their rooms is substantial.

However, if you place that same capable sub on a concrete basement floor, the floor does *not* transmit the same tactile energy that the suspended floor did. You may still get the percussive bass, the punch and slam. However, you won't get the bass that makes the room (floor) shake. You can try to duplicate the tactile bass with shakers and transducers. However, unless you are on a riser with tactile transducers, you'll never get the same tactile response that you get from a sub on a suspended floor.

I know first hand that this is the case. My HT is in the basement on a concrete slab. I have a Crowson Tactile Transducer underneath a leg of the sofa. It provides great tactile response to your butt and body. However, when your feet are on the floor, and there is no tactile input there, it's an almost unnatural sensation. In my friends' rooms, with suspended floors, when you receive tactile feedback through every body surface that is touching a room/furniture surface, the sensation is much more "natural" and appropriate.

Very well said craig. I have my ht gear on second floor . My modest Bic H-100
on some bass heavy scenes will shake the floor a little bit. what would a more
capable sub will do?

My sub shakes the **** out of my furniture, and my HT is on concrete slab.

I have no complaints on movie bass. It's rock music, when I crank it and my sub runs out of steam way before my towers do that concerns me.

I have two room that have subs. My family room has the right wall open for 1/3 and a half-wall for the next 1/3. The seating area has a solid wall. We've had awsome bass there from an old SVS 25-31 PCi. There is a little 10" sub in there that works great for TV.

My home theater is an open, family room styled theater. It has a 6 ft opening in the middle of the back wall that opens to the rest of my large basement (you can see pics in my gallery). Again, I get incredible bass response in there... plenty of tactile, visceral punch and infrasonic swimminess (15hz). This is with the new SVS PC-U, which is a highly capable sub. My old Ultra did well in there, too.

FWIW...

I have an 8' opening in the middle of the right wall. Which is almost 1/2 of the rooms depth.

Can't tell if this has been covered yet but I used to have a room with big openings and what I ended up doing is locating the sub behind the sofa and close to my seat. The room response was much better (flatter) and the tactile feeling was great!

Just an observation:

If the opening(s) are in a corner, the bass is much better.

Opinions?

If the opening is in a corner, the opening acts like a perfect bass trap in that corner, (an opening reflects no sound, which is what a perfect bass trap would do.) If you have the opening mid-wall, the "bass trap" is in a much less useful position for trapping bass.

It's not that the midwall opening ruins the sound. The room is doing that. It just shows that your room needs corner bass traps, (as do almost all rooms if you want good sound reproduction.)

Craig

Well if you close the room the sub will sound better! :D

I plan on moving soon. Money wasted.
