Spkr size vs. Room size
It depends how you define large.Box speakers suffer/benefit from up to 12dB/octave of room gain once half a wavelength (1130 feet / frequency / 2) exceeds the longest dimension.Put a box speaker with low bass extension in a small environment (like... 
Projector Screens - novice needs help
The best home theater screen size for you will vary WILDLY (perhaps by a factor of 2) based on personal taste, source material, aspect ratio, your sensitivity to source artifacts, what projector you use, and how you feel about it's artifacts.You r... 
Boomy bass in home theater room
Dipole bass helps tremendously - perception seems to be driven by more than just steady state response. Unfortunately, most of the Martin Logans cross to monopole bass drivers by the time they reach 200-300Hz. You can do that down through the seco... 
System evaluation
The display is way too small - a display width of 2/3 seating distance is a nice starting point which can be adjusted up or down depending on preference (once you've adjusted to movie theater scale). This matches the subtended field of vision you'... 
replacing tweeter help
Pros: You'll eliminate any high-frequency break-ups that cause audible in-band IM distortion.Cons: If the tweeter is not otherwise identical you should redo the cross-over. Good luck. 
Home audio drivers vs. car audio drivers
Fs, Qts, and impedance.When you put a bass speaker in a rigid enclosed area you experience 12dB of gain per octave you drop below where the longest dimension equals half a wave length. So to get flat bass inside a car you need the sub woofer to ro... 
where do you cross over your ht setup
I run full range mains (F3 30Hz, F6 20Hz, Q=.5) with an 80 Hz second order high-pass for excursion control, but plan on switching to 40 Hz 4th order.Sealed box excursion increases 4X with each octave lower, dipoles 8X - so although my (half-space,... 
What speakers use SEAS or SEAS-sourced drivers?
Siegfried Linkwitz's open-baffle Orions use an Excel Millenium tweeter and Excel W22EX001 as a midrange. Bass duties are handled by a pair of 10" Peerless XLS drivers (Q=.5, anechoic F6 of 20Hz, no room gain).http://www.linkwitzlab.comThey're wond... 
Which is more important?
The room and speakers together are the most important component. The two interact and should be viewed as a system. Room gain can supplement the bass of a smaller speaker or make a big one too bloated. How the room reverberates can determine how b... 
Maximum distance from my monitors
Move the chair. Somewhere arround an equilateral triangle seems to work best - you're still getting a seamless sound stage, although it can wrap arround you nearly 180 degrees.(I'm at 7' from a line drawn through my tweeters which are 8' apart - m... 
Lost in 7.1 hell DLP projector / Plasma setup ?
1. You cannot achieve an immersive field of view at reasonable seating distances without using two-piece projection (front or rear, with rear meaning a separate room with a projector and not a consumer RPTV). Here you must leave your TV perception... 
Less is more? Where's the midrange question -help
Good drivers with uniform frequency response and low distortion are not cheap. Good passive components are not cheap. By the time everyone gets their markup the sticker price can be 10X what the components cost. Ergo for some definition of "afford... 
Center speaker placement
In line with the TV. You will probably have bad results if it's on the resonant cabinet of the TV and in-line with the large front surface.On a floor stand a few feet in front works well. Suspended above the screen works well too. Height differenc... 
Problems with Movie Dialog-Just the normal?
Many movies have a lot of dynamic range. If you play your dialog back at a reasonable level (say 70dB), the peaks can be very loud (up to 107dB from the LFE channel using the default encoder settings0.Reduce the dynamic range via compression (this... 
Center Channels sound crappy
1. Placement. Any speaker not designed to be placed on a TV or in an entertainment center will sound bad there - and most center channels aren't. Finally, a plastic TV cabinet is also very resonant. 2. The horizontal MTM orientation. There will be...
