| Low freq. from small drivers? Is it possible The specs of small drivers can have a low cutoff - my bedroom speakers have a pair of 5.25" mid-bass drivers and are flat in-room through 30Hz.In practice it doesn't work.SPL is purely a function of displacement and frequency. Displacement require... | |
| 7.1 vs 5.1 With direct-radiating or bipole surrounds, 7.1 yields a quantum improvement in immersion over 5.1. Not as noticeable as adding surrounds to 2 speakers which can provide a near 180 degree sound field but still significant. The added surround back c... | |
| Sound Proof??? Sure. In theory you could build a free-standing room arround your system with double dry-wall, staggered studs, an exterior door, and mini-split system to keep it cool. Tear it down when you move.In practice there's little you can do. Sound will t... | |
| resonance and sealed enclosures A sealed speaker's response at resonance (Fb) depends on how the system is damped (Qtc).A sealed speaker acts as a second order high-pass filter. Ultimately it will roll off at 12dB/octave with Fb determining where the roll-off starts and Qtc the ... | |
| Help me plan my next upgrade 2-piece projection either front or rear. For an immersive home theater experience you want to be sitting arround 1.5 screen widths. At normal living room seating distances (beyond 9 feet) this isn't possible with the largest one-piece consumer tel... | |
| Standing vs. Seated-Big Difference in Bass??? Nodes and anti-nodes are a function of spacing between you, the speakers, and the boundaries.You need to move yourself, your speakers, or the room.The best locations for bass and midrange/imaging are probably different. | |
| Home Theater Volume ? Power doubles for every 3dB, although assuming you don't exceed the speaker's power handling (not likely) and don't have audible distortion it's not an issue. | |
| HELP - How Hard is to Blow a Bass Driver If the woofers were making clanking noises, their voice coils bottomed, the formers may be deformed, and may now rub.Otherwise don't worry about it. | |
| Home Theater Volume ? Most action movies are mixed with a huge amount of dynamic range. Big changes are normal.If you can't hear the dialog at low volumes you have a problem of some sort (speaker placement and acoustics are candidates when the system is properly calibr... | |
| What's the chances of this Let me explain : You can use a Xantech IR router like an RT8 (~$250, also requires a power supply, receiver, and emitters none of which are expensive) and program your universal remote so that it sends device selection codes before and after the offending commands... | |
| 7 or 5 speakers 7.With the stock decoding algorithms on 5.1 sources, you get a bit more immersion from the side + rear surrounds. THX-EX encoded source will put sounds arround, beside, and behind you. Your Lexicon will also enhance pans from the front to rear spe... | |
| Ideal distance from TV to sitting/viewin position 1.5 screen widths is a nice compromise between immersion and a soft image with high quality NTSC sources (DVD), and is a defacto average seating distance for home theater applications. This translates into the following viewing distances:Diagonal ... | |
| Next piece to upgrade? Projection. It's impossible to have an immersive experience at anything approaching normal living room dimensions without using a two piece projection.With your current setup you'll need to sit arround 4.5' away to have the theatrical experience.G... | |
| Best drink while listening to your rig? Single malt: The MaccallanBeer: Barney Flats Oatmeal Stout or Sammy Smith's Taddy Porter (Anderson Valley makes a better stout) when I need a black beer to brighten my day, Bridgeport IPA or Fuller's ESB when I want a light beer. | |
| Mitsubishi 82 inch big screen TV or projector? If you plan on sitting more than 9' from the set or want multiple rows of seating you'll want a screen bigger than 82" diagonal. Probably much bigger.Beyond 13' even a 120" diagonal 16:9 screen is going to start getting small. I'd consider it too ... |
