| Class A vs. AB vs. D... can you hear a difference? Still not convinced with the high frequencies of any class D I've heard, but I've only heard a handful. Could say the same about most tube amps I've heard. Still have concerns about AC pollution of SMPS but that has become universal.Having a pair ... | |
| Speaker Sensitivity Question... Most powered subs don't have an active high pass for the main speakers although they do have an active low pass for the subs. That means that the main speakers still get the full range signal and the sub supplements the low frequencies.If you do a... | |
| Sloped baffle Looked up quadrature and unless you're masochisticly inclined to imaginary vectors, this might be easier...http://sound.westhost.com/ptd.htm | |
| Sloped baffle Thanks Roy. Again, you beeped. I'll counter with pop, bang, whack, pow, and all the other 60's Batman fight words that seem to have something else in common. Not arguing you're goal of recreating as accurately as possible but the words describe mu... | |
| Sloped baffle The Holm site has an interesting, albeit monotone, video tutorial how these things work. Specifically his, but generally for all. | |
| Sloped baffle Holm Acoustics also offers a similar product but it's more expensive. Without the preamp feature, there's miniDSP, Ground Sound modules and what I consider the best of the 'pro' units, Xilica, which is also used on the top-of-the-line Legacy speak... | |
| Sloped baffle To answer Al's rephrased question or Bruces's origional, I'll give the example of the speakers I'm working with lately. The midwoofer is an inexpensive 5" that has a fairly nasty and fairly normal breakup around 5KHz and rolls off rapidly after th... | |
| Sloped baffle Even with DSP, bet there's still a market for $300 Revelators vs. a $20 Silver Flute and vice versa. | |
| Sloped baffle Those S5 plots are actually quite smooth. A sign of well matched, quality drivers, a good cabinet and unobtrusive crossovers. That phase dip in the bass is fairly standard and hard to avoid. It's from the woofer, not the xover. Other than the low ... | |
| Sloped baffle How fast is the train travelling? | |
| Sloped baffle @BifwynneFor the first part of your question, you misunderstand. Pass band is the part of the frequency the driver is covering, unattenuated, within the filter. Actually, I used the term technically incorrectly in the BSC context since that is att... | |
| Sloped baffle For individual drivers, cone woofers have voice coils and are inductive. So, yes, they do have phase shift as frequencies increase. Some are more inductive than others. Even dome tweeters have some degree of phase shift.A first order, parallel low... | |
| Sloped baffle The DIY forums and this one have something in common. Very rarely does anybody listen to any advice or criticism that they don't want to hear. | |
| Sloped baffle I have no doubt Roy is sincere and his efforts are genuine. I don't have enough information to intelligently debate his views either way. Beep is an interesting phenomena in itself. | |
| Sloped baffle Bomb,That was not my intended meaning. Simply put, we're human.Obviously you have your opinion and I'm not trying to argue, passive aggresively or otherwise. I may have reacted a bit sarcastic when I thought you overstated.Perhaps you can explain ... |
