| Sub output: Is it the woofer size or the rated RMS >One correction - membrane of 18" speaker should be 10.5 times heavier because it should be 3.24 times thicker and the area is 3.24 times larger. That is probably why definition is getting poor (too heavy).It's entirely about extended frequency... | |
| Sub output: Is it the woofer size or the rated RMS >A driver with twice the area (say a 15" driver versus a 10" driver) can play 6dB louder. A longer stroke often goes with the larger diameter; if that doubled from 12 to 24mm you'd get a total of 12dB more output at low frequencies given enough... | |
| Sub output: Is it the woofer size or the rated RMS >In any subwoofer output, how important is the Watt output versus the woofer size?This also depends on the frequency range of interest.The air you need to move quadruples with each octave decrease in frequency.A driver with twice the area (say ... | |
| Sub output: Is it the woofer size or the rated RMS >In any subwoofer output, how important is the Watt output versus the woofer size? Speaker efficiency is at best proportional to cabinet size and inversely proportional to the cube of the low frequency cut-off.So all else equal, it's going to t... | |
| How Important is Getting Your Rack Out Swapping my 32" Trinitron + stand for front projection was the best thing I ever did for my sound-stage (speakers 8' apart and 4' off the front wall). | |
| Your average size city apartment deserves speaker >But more often than not the size of the room should play a bigger role in determining which speaker to choose.What are your placement constraints?If you're not constrained by SAF, Linkwitz Orions will work well 4' off the front wall and 8' apa... | |
| COnverting Audio Equipment Voltage From 110 to 220 A lot of power transformers are built with dual primary windings. You put them in parallel for 120V and series for 240. Some even have taps for 100V Japanese power.Look inside your equipment and see what's in there. For example some Adcom amps hav... | |
| Projector VS some other type of HDTV >Apart from the fact a projector gives a much bigger picture, is there any reason to purchase one over LCD or plasma HDTV?That's precisely the point. It's not possible to get a theatrical sense of immersion from a one-piece consumer television ... | |
| TV Selection: Two Questions >2. Viewing position is mostly straight on about 12 feet from screen. What size?The biggest you can afford. 110" diagonal is a nice compromise which leaves scope DVDs only a little on the small size.Don't worry about 1080p at that distance, sin... | |
| 1 Room 2 Systems Even with the speakers 3-4' off the front wall and 8' apart, upgrading from my 32" Wega + stand to front projection was the best thing I did for my sound stage.Although a blanket in front of the TV may help the highest frequency reflections it doe... | |
| OPamps still inferior to discrete circuits? >Yes - quality op amp packages can have outstanding performance. The only reason to use discrete components is for building output side of power amps. This is because of the high heat.You get better thermal tracking and lower cross-over disorti... | |
| What's next for the ultimate sound quality? >The question is what's next?The physics of conventional speakers are inherently flawed, where conventional speakers have non-uniform polar response especially in the cross-over region.The polar response is too non-uniform to sound natural, esp... | |
| Subwoofer meshes well with 2-channel? >I hadn't really given it much thought before, but will a sub work well with a 2-channel system (when reproducing music) Yes. >or does it just muddy things up? I have full-range speakers (Tyler Linbrook Sig's) that go down to 30hz or so, and... | |
| connecting wireless. For standard definition, you can get cheap wireless solutions.For HD, Gefen and Belkin offer wireless HDMI for $900-$1500. | |
| Room: 16 x 18.5 how big of tv? Depends on your seating distance. I wouldn't go below 100" diagonal for an 11' viewing distance or 110" for 12'.Seating at 1.5 x screen width for a 16:9 screen is an OK compromise which doesn't make lower quality sources too big or good scope DVDs... |
