| 5.1 to 7.1 >So I an wondering if its worth changing to 7.1. Yes. It's a quantum improvement in envelopment.>Furthermore I run QS8's on the sides of my stage, so do I honestly need to run QS8's in back too? Sound tracks mostly place ambiance and effects... | |
| What's with 4 ohm speakers? I should probably proof-read better before posting>The moving mass Mms works as a capacitive inductance Cmes. capacitive impedance>When cross-over designers compensate for that with a series load power impedance increases at those frequencie... | |
| What's with 4 ohm speakers? Atmasphere writes> I wrote:> Those of us with a little technical knowledge accept and expect it because at lower frequencies dynamic loudspeaker driver output is proportional to voltage.>The statement is ambiguous. We know that doubling p... | |
| Adcom Amplifier Speaker Protection Power amplifiers often (usually?) fail with a shorted output device that causes DC output at the positive or negative rail voltages.Adcom amplifiers have fuses on those rails (some with them in holders on the back panel) which will probably blow b... | |
| What's with 4 ohm speakers? AudioKinesis writes:>In reply, I'd like to point out that, with the same 4 to 16 ohm impedance difference described here, the power that a transistor amp puts out varies by 6 dB, because it is putting out constant voltage rather than constant w... | |
| What's with 4 ohm speakers? I wrote:Apart from this edge case the effects on distortion aren't interesting compared to what the speaker is adding to the sound.That's not quite right - my power amplifier biases run towards push-pull solid state class AB for practical reasons ... | |
| What's with 4 ohm speakers? Using solid state amplifiers without output transformers a 4 Ohm nominal impedance allows peaks 3dB louder than 8 Ohm speakers with the same cabinet size and low frequency cut-off which ultimately limit efficiency per Hoffman's Iron Law. This is g... | |
| big screen - two channel system enough for dialog? FWIW, I'm speaking from experience here. I ran my 100" diagonal setup with mains 4' off the front-wall, 8' between tweeter dome apexes, center channel off. It's not an issue. | |
| big screen - two channel system enough for dialog? >If I have a large screen (100"+), will I need a dedicated center channel to hear dialog well??No.It may even be more intelligible without a center channel where you don't have an acoustically transparent screen which forces center channel plac... | |
| Frequency Response >11-01-12: Drew_eckhardt>The right fix (which works in more rooms and doesn't cost you detail which comes from the direct sound level) is more driver + baffle combinations sized appropriately for the wavelengths being reproduced although tha... | |
| Frequency Response >11-01-12: Realremoyou might hear speakers' mid-range being described as "ruler flat" across a certain frequency spectrum. That basically means there are no peaks or valleys in the response that affect the lows, mids or highs. This is my unders... | |
| Frequency Response 1) You probably can't hear above 16KHz on music2) The lower bound is what the speaker will reproduce at a low level, not what it will reproduce at a useable output level so it's meaningless. | |
| Best way to hook up a sub? 10-28-12: Doggiehowser writesIs this for a home theater or a hifi system?>It's always a bit difficult to integrate a subwoofer with main speakers. One thing I try not to do is to muck with the main speaker's crossovers. The speaker designers ha... | |
| Need speaker for a small space and close to wall Triad in-wall.There are two reasonable speaker placements:1. Well into the room. The greater of 4' and half the distance to the listener is a nice start which will limit how deep the SBIR null is and get it down below 70Hz where a sub-woofer might... | |
| Contribution of processor in bypass mode It does whatever you believe it does.When people don't know what they're listening to there are all sorts of things with effects below the threshold of hearing that are inaudible, even 16 bit analog to digital then digital to analog converison.Kno... |
