Heat/Efficency of Speakers shadorne... if I say a speaker churns out between 99% and 90% as heat then that equates to an efficiency of 1% to 10% in sound energy ...Quite so. But I don't think you can cite a loudspeaker system with 130 dB sensitivity, which is what would be... | |
Choosing Sub-woofers. Please advise ASAP. cedargroverWell, the frequency (i.e., the period between when the derivative is 0) won’t change based on driver size but cone velocity will, for a given output.The "cone velocity" is the driver's frequency. If asked to produce a 32 Hz tone, the... | |
$2000 turntable system leotis ... need speed controller. Looking at Phoenix Eagle with Roadrunner tachometer ...You might want to reconsider the Phoenix. The word is that the company is going out of business at the end of the year. | |
Choosing Sub-woofers. Please advise ASAP. mb1audio02If you want to make bass, you can either move a large driver slow or a small driver fast. That doesn't make any sense. A driver's movement corresponds to the frequency it's asked to reproduce. If it's a pure 32 Hz tone, the cone will ... | |
Do equipment stands have an impact on electronics? ethan_winerNo, the burden of proof is on those making the claim.That's absurd. This is not a scientific forum, it's a hobby forum. No one here owes you anything.Regardless, your claim is silly, because not all assertions are equal. If I tell you ... | |
Class D Technology kijanki ... electricity in speaker cable flows in both directions canceling the most of RF (if any) ...There's nothing inherent about an AC circuit that makes it immune to RF, so it isn't clear what your point is here. | |
Do equipment stands have an impact on electronics? ethan_winer ... I'll never understand why some people are so willing to measure the wrong things and come to a wrong conclusion, when it's so easy to measure the right things and get the right conclusion!Under these two scenarios, it's typical... | |
Resale value tonykayInitially, I said that buying equipment was analogous to the stock market. "Analogous" simply means that something is like, or similar to, something else-not precisely the same. My comment was first taken out of context, and then blow... | |
Heat/Efficency of Speakers shadorneYou might want to check your reading comprehension while I am checking my math! If 99% of energy is lost as heat as I stated then this makes a speaker very inefficient - a mere 1% being converted to acoustic energy - exactly what you c... | |
Turntables hit the mainstream lpretiringI want to know how long do I have to wait for reel to reel to begin it's comeback?It's already underway.http://www.unitedhomeproducts.comhttps://horchhouse.com/project-r2r/Of course it's not likely to enjoy a resurgence equal to that of... | |
Heat/Efficency of Speakers redfuneral So I should assume all power(90+%) drawn from the wall will end up as heat. I should be looking to minimize the wattage at the speaker terminalsNo, not at all. You can achieve substantial increase in efficiency by choosing an effi... | |
Heat/Efficency of Speakers shadorneSpeakers typically churn out between 99% and 90% of energy as heat. You might want to check your math - most speakers are much less efficient than that. A speaker with 92 dB sensitivity is only about 1 percent efficient.As for the OP, the... | |
Filter tweak for digital backwash? randy-11Why aren't the engineers designing expensive audio gear dealing with these problems?I thought it was pretty easy to deal with noise ...I think working to reduce noise is a very tricky business, and I agree with georgelofi that there are m... | |
Please help! - Buy VPI Classic or keep Technics 1200 chakster@sbank for those who don't know: KAB site is down for a few years,The KAB site works fine for me. | |
Nakamichi high-com II in record chain only or listening / record chain (vinyl source only) Why would you want to use a High Com with a CD recorder? The High Com is a compander designed to improve s/n with sources prone to noise, such as analog tape. It's a complementary device so in use, it must be both in the record and playback circuits. |
