Construction starts soon--feedback appreciated!

Hey Everyone,

We're going to be digging the basement soon, and since I've taken about half of it for a theater, I'm trying my best to do it right!

On the attached, you'll find a dedicated theater space with the third row converted to poker table and PC use (photo/video editing). As a result, I've had to make some compromises...but picture and sound from the sweet spot is a priority.

Any thoughts, suggestions or feedback would be great, especially on:
- Surround speaker placement?
- Acoustic management with the odd wall shapes/dimensions in the room?
- Distances/measurements?
- Seating ideas?
- Riser height & config?
- Etc.

Basically, the only part that is committed is the outside walls...all else can still be changed. One more thing - 10 foot ceilings throughout (minus some space for ductwork at the back, and behind the screen).

Thanks in advance!

Quill

Interesting space and creative entrance/riser design.

If you are like most of the your AVS brothers you will be using the front row over 90% of the time, What that means is that for 90% of the time the side surrounds are too far back.

Look at Roman's web site and all his posts (RSH) about theater chairs on the theater accessories section of this forum. As postioned the rear row is too far forward, your feet hang over the edge a foot or so.

I would go with two sets of side surrounds, but I am not sure about head clearance for the surrounds on the entrance side. You could pole mount them if you have the height between the ceiling and the raised platform. Other wise you could switch to something like this: http://www.triadspeakers.com/products/iws4sur.html
mounted in the ceiling. Nice size space you have to work with and I am a fan of the AT screen concept, use one myself. If you have any questions, happy to answer them.

What if you extended the wall on the right side, enough to add a pair of in wall surrounds for the front row. Leaving the second set of surrounds where you currently have them? You would need to square off the steps.

This is why I love this forum--awesome idea! It also helps solve my other problem of sound transmission through that curved staircase wall to the main floor!

I think you may need to scale back your seating from 5 a row to 4.

+1. My room is 16' wide and I barely fit 4-across, and that was with a center loveseat arrangement for the recliners...

Good call....is there a good planning site for this? The berkine site is no longer available (obviously), and it's difficult to spec out using the spec sheets only.

My only prerequisite is that each row has a middle seat....for me. I don't know whether I'll prefer the front or back yet, so I need to hedge my bets and have a middle seat in each...

As it is, with the 60"DLP in my current home, I have an ikea chair that I pull out and place dead center (in front of the couch).

You can use google sketch up and import different objects into it. If the object does not exist predesigned, you can attempt to make one (which would be time consuming). You can also import an object and stretch it out to your dimensions.

Yeah--I liked the berklines site because I could make the seating group I liked, then work from there. Adding angled seats together, then calculating the width of the curve by adding \\0V000V0/ or \\0V0|0|0V0/ is....hard

The attached room is about a 1' wider and three feet shorter than your room. You can see the scale of the seating to the room to aid your visualizing the result. I would, as Mike suggests, come up with a method of getting surrounds oriented for each row of seating; however, the Triad Silver Surrounds would not be your better choice ... a Triad LCR type speaker would be better (when you use multiple side surrounds, use a monopole speaker). Due to the distance from the back of the room to the front row, again, you'll need monopole surrounds and some pretty capable ones at that mounted as high as possible. As currently laid out, you'll never hear the rear surrounds and will be blowing tweeters daily to overcome that distance.

So if I understand, a surround speaker to the left and right of each row would be optimal. This would make for 4 "surrounds" and 2 "rear" speakers? A few questions:

- Would I simply split the surround signal coming out of the receiver and amplify it so that both right surround speakers receive the same signal?
- I understand the rears being monopole (and moved forward if possible), but assuming a pair of speakers per row, would the sides be dipole?

Thanks!
