I actually wasn't, which is why I asked. I don't plan on mine being right on the floor. I didn't want half my speaker to be sunk below the screen, if that makes sense.
So my bigger question was in line with how high up off the floor is too high for a tower speaker.
I'll probably do the best I can. I'm a bit limited with ceiling height where I'm building...so I have to make sure I have clearance for 2nd row.
Appreciate the advice/suggestions.
If you're placing the speakers behind an AT screen, why use tower speakers? You could instead use LCR-type speakers and use Bass Management to send the bass to the subwoofer(s). I assume you'll be using subwoofers as all well-designed Home Theaters are designed around good subwoofer systems. There are huge advantages to using subwoofers, including:
- Placement Flexibility that is not available with tower speakers, (Towers need to be placed where they image best and present the best soundstage. These placements are virtually never the best placements for bass reproduction.)
- Amplifier Headroom Increases, (Bass is the most power intensive portion of the audio spectrum. Redirecting the bass to the subwoofer channel(s) removes it from the mains channels, and therefore from the main amps and speakers. This frees up significant amplfier headroom, allowing the main amps to reproduce the rest of the spectrum louder and with less distortion.)
- Reduces Driver Excursion. (Every octave of deeper extension doubles driver excursion. Going from 80 to 40 Hz, doubles excursion. Going from 40 to 20 Hz doubles excursion again, or 4X the excursion at 80 Hz. Using 80 Hz crossovers on the speakers reduces woofer excursion significantly and allows the woofers to reproduce the >80 Hz bass louder and cleaner with less distortion.
In terms of mounting your screen, with a two-row theater, you need to figure that piece out before you calculate speaker placements. Here is a calculator for figuring screen height vs. 2nd row riser height:
Riser Height Calculator or you can email Mike Garrett and he can send you a spreadsheet that will do it for you: [email protected]
You'll need the height of your screen from the floor, your seating distances for your first and second rows and your seated eye height for each row. To calculate the height of the screen from the floor, you want the size of the screen, and it's aspect ratio. This will determine the height dimension of the screen. It is most optimal to have the eye height at 1/3 to 1/2 screen height. You'll need to decide whether the first or second row will be the primary row, and base your screen height off that row. Alternatively, you can split the difference between rows and use that height, which won't be optimal for either row, but will be "less-bad" for the non-primary row.
To calculate seated eye height you need the height of the seating plus the seated torso to eye height of the tallest listener you expect to have in your theater.
If you would like some help with these calculations, please post your anticipated screen size, aspect ratio and seating distances for each row, as well as room dimensions. Any info you have on the seating, such seatback height, recline clearance, seating height, etc. would also be helpful. Do you plan to build a false wall to mount screen in?
