| The Great Speaker Quest You haven't enumerated dipoles in planar, ribbon, or cone driver form.This is a very different thing from omni (there's actually less reverberant field generated than with conventional speakers at lower midrange frequencies, where you're trading m... | |
| 4 Ohm Speaker with an "8 Ohm Minimum" Reciever >Stanwal...AWG 20 wire is 0.0119 ohms per foot.150 ft of such wire (75ft round trip) would be 1.78 ohms.Not really a problem, especially if the speaker is 8 ohms.Sure, but that "8 Ohm" speaker can drop to 6 Ohms at some frequencies and increase... | |
| Can you get "bookshelf sound" from a floorstander? > Can you get "bookshelf sound" from a floorstander? Sure, but note that 3-way designs can have double the parts cost of 2-ways since the bass drivers are expensive, the mid-range needs to be a band-pass instead of a low-pass, and the low cross... | |
| Need to replace Subwoofer volume control >Drew_eckhardt...Any time two pots are ganged there can be a tracking error. Why would a log pot be made as a series of linear segments?For a pot to have log taper resistance per unit of rotation needs to increase. With wire-wound pots the wind... | |
| pixelization? >Thanks for all insightful responses. My only questionis why does this only happen on HD channels?Bit rate allocation. For the same level of pixelation 1920x1080i takes 6X the bandwdith of standard definition and 1280x720p 5.3X. | |
| Need to replace Subwoofer volume control >Stonedeaf...NOT Linear taper. It should be Audio taper, but these are so hard to find that Log taper is usually substituted. Characteristic of the original pot could be determined using an ohmeter once you get the thing out of the circuit.Some... | |
| US only sales WHY??? >Shipping paperwork is a HUGE hassel. There is none of that if you just sell in the US market. I sold an item to someone in France one time, and the associated paperwork took me an extra 4 hours. I haven't spent more than 10 minutes looking up ... | |
| US only sales WHY??? >As a UK based audiogon member, i'm constantly surprised at items only being offered to the US, and not worldwide as most ebay items are now, why is this?Some people have had bad experiences and other ones are lazy.I'll ship outside the US via ... | |
| pixelization? This is a natural consequence of how video compression works.The images are split up into 8x8 sample blocks which are converted into the frequency domain where you have an average level for the block plus the changes across the whole block, that o... | |
| Possible to use sub without preamp? Sealed speakers with a second order sub-woofer high pass will mate well. Anechoically you'd want the roll-off points to match, although in your room you may want asymetric roll-offs.If you have enough adjustability in the sub-woofer low pass filte... | |
| Speaker Technology over the last 10 years >does anyone think great strides have been made in crossover technology, especially with the availability of a such a variety of capacitors and resistors.The passive components don't matter that much.Inexpensive computers which can make gated m... | |
| What matters most in speaker design? Uniform polar response with a slow monotonic decrease in total power above a few kilohertz preferably with less output towards nearby objects.Getting there is a function of driver diameters, driver bandwidths, spacing, baffle shape/dimensions, and... | |
| High power handling speakers GedLee Nathan 10 for $1100/speaker? new.95dB/1W/1 meter. The pro-sound woofer will take 350W of pink noise with a 6dB crest factor and is rated for 700W on music. The compression driver will be fine at those output levels.Sub-woofers are required.... | |
| Bass, more or less? >I'd expect the Earl Geddess multiple woofer strategy (deployed in the Audio Kinesis Swarm) and throw-catch double bass array (An array of woofers on the front wall spaced to create an essentially planar wave which is caught by a matching array... | |
| Bass, more or less? >Let me first say that I have a pair of Sonus Faber Guarneri that I have owned for several years now. I am driving them with a Mcintosh 2102 (100 watts per side). I recently read an interview with Sonus faber founder Franco Serblin in wich he m... |
