Long story short... we are renovating the house to sell at some point in a year or two, and my wife has agreed to let me move the HT into a bigger room. Problem is, she's making decisions faster than the light from my plasma can reach my spinning head (so I have little time for research today).

I greatly appreciate any help you can offer here, or in pointing me to appropriate threads. TIA!!!

  1. I would like to improve acoustics beyond just bare walls and floor as much as possible. Would it make sense to construct a room-within-a-room for this scenario? What are the benefits?
  2. I plan on changing out my B&W's for the Revel Ultima Salons and a new Voice-2 center which will sit on a new stand under the wall-mounted TV. Should the centerline of the screen be at eye level?
  3. What are the pitfalls of buying used HT seating. I need only 2 or 3.
  4. More questions later, but I'd welcome any suggestions in advance!
EDIT: Just to try and collect my upgrade activities in one place, I've included links to some of my related threads:

Where, Oh Where Does My New Center Go?
A Sound Renovation for the Green Room

And here's a teaser of things yet to come! (lifted from the REW Online Help Manual)

Room within a room is really only for sound isolation. If you want to keep sound out or sound in that is the best option.
A compromise is needed for the centre channel. you ideally want it at the same height as the tweeters on your mains but that makes the screen to high in most cases.

Don't overlook Chane speakers. He has his pre-order special going on now for his latest iteration of the A5. And should come out with his much anticipated L7 with matching center by the end of the year. These are expected to be a very big step up. Just a thought. I do know that Sonnie just bought another pair of the A5's for his room.

Thanks for your patience! I could have looked it up myself, but am in a hurry to shorten the learning curve.

So is center-line tweeter alignment the reason for risers? Or are risers used as a space to create a bass trap?

No doubt Chane's are top notch! I plan on eventually getting some for my surrounds. I should have explained the center needs to match my existing Salons. :R

It can serve both reasons.

While the riser is a great bass trap, the main reason is to give the people in the row behind a better/unobstructed view of the scree,.

Thanks, Tony! Two down and ??? many more to go. I guess a room-within-a-room would bust any ill-conceived budget I came up with. Worse yet, the bigger room would now become smaller. If we were staying there long-term, sound isolation would be higher on my list because the resonating walls definitely need reinforcement.


I obviously need to keep realistic expectations about the new room, especially since we could move shortly after it's finished. So aesthetics come in a distant second to functionality. I'm pretty sure that a good viewing experience is controlled by lighting and seating distance. Good sound is controlled by speaker positioning and acoustics - first position, then acoustic treatment, then signal processing from the likes of Audyssey, etc. I at least plan to distance seating far enough from back wall to properly locate surrounds.

I guess what I'm trying to ask is:
  1. If my wife wants to put up this paneling, is there something I can put behind it to help acoustics?
  2. What's involved in building a riser and is that something a novice could do?

That paneling wont absorb or let through any sound so putting anything behind it wont make much difference. As far as what to put in the walls Roxal safe n sound is my goto product.

Are we talking a speaker riser or a riser for seating? both are easy to build just use 2x6 boards for the frame and glue and screw 3/4" plywood to the top to keep vibration away.

Both, I think. If the seats are at floor level, then ears should be about level with the (horizontal) center channel IF it just sits on top shelf of wide rack. That would put the center of the screen a little above eye level. The mains tweeters would be a little above that. Vertical distance from center channel tweeter to mains tweeter would be a foot or two! So my setup will never be ideal. I think I know what you're saying, though. From what I can remember, Sonnie's CCC has a riser for both the center channel and the seats, which effectively puts the mains below sea level so-to-speak. But not sure if the same principles apply because his Martin Logans don't have a single tweeter. :R

Ive got my mains below the screen and that in turn raised my screen so the centre of the screen is definitely above the "ideal" height. But my tweeters are at just below ear height, I have them angled back slightly so everyone gets the right amount of highs. I just have my mains on some black square milk crates coverd in a black cloth LOL

I have been thinking about front of room traps for a while. Of course, your HT screen gets priority. In my room, I will move it up so that I have front room traps to above ear height. In your case, you might consider traps across the lower part of the front wall below the screen down to the floor.

Reason, absorption rather than reflection from the front wall illuminates reflections that cause Imaging to wonder with different notes and tones with some instruments. Also quickens the decay of nodes and low-mid frequency reflections, getting them to die down quickly. It will definitely improve the impression of fast bass and will improve Imaging and detail.

I am getting ready to build a set, will do a build thread, but my design prioritizes 2 channel sound while allowing for a good home theater set up also.

I think that is what about 99% of us are looking for!

Kind of a random comment... but your chosen L/R speakers are about 4 1/2 feet tall. I'd be inclined to do everything I can to ditch the horizontal center channel and get third Ultima Salon in its place.

Just in my opinion, your Samsung PN60F8500 won't have viewing angle issues (if the TV position is slightly higher)... and the benefit of using an actual tower in place of a center channel will be pretty huge.

I would agree with Todd here, and to take it a step further, ditch the TV and get front projection with an acoustically transparent screen. Then put that third Salon behind the screen. I'm sure the wife will love the idea . . . :D

Eeek, again!! If only I had the funds at the moment to go projection. I'm limited to about $3k for everything. If I could find a buyer for the Salons and the B&W's, I'd try to get matched speakers for a 7.1 setup. Already have the electronics to drive them. I guess I should have let on a little earlier that the bigger room is only marginally so (13x11).

Sometimes the truth hurts, and you're right about the height. TheSalons weren't meant to be HT speakers. I just hate losing an arm and a leg on them. I also hate the act of selling - just no good at it.

So it seems as if this venture is done before it begins! Can you say "easily discouraged?" Methinks it best to save up for the goodies and just get some used seats for now, especially since we're in temporary quarters until we sell.

While I see-saw on the options, guess I'll start planning the speaker layout, as limited as that may be. Somehow I need to get those surrounds a little over ear height and behind the LP. I remember seeing a recommended angle and range, but don't have it handy at the moment. I do know where a sketch pad and pencil are!

Hey Louie ol buddy. Not sure which angles you're after, but I've got these...

Maybe 25-40deg above ear height.

Perfect! Thanks for that my good friend Willis! I appreciate the help, though I should probably have looked it up myself. :sneeky:

So if it were your coin, would you:
(a) lean more toward getting the center channel for the uber performing Revels, or
(b) Trade the Revels and B&Ws in for a matched system, say Golden Ear Tritons or an amazingly high bang-for-the-buck Chane A2Rx system?​
