| First order/Time Phase-Coherent speakers discussions Hi Richard, I have read your review on Parts Express several times as I find this speaker that you drastically changed a true bargain in the audiophile world. I look forward to hearing the results of your constant resistant technology combine... | |
| Spread Spectrum Technologies The Ambosia Pre, the Ampzilla 2000 mono blocks and the Son of Ampzilla 2000 are all JB. The Thoebe II pre and the Son of Ampzilla II amp are both designs that are largely Jim's, but have been tweaked and finished by W4S. | |
| Crossover Capacitor In Parallel with Woofer It is certainly doing impedance correction, but 6 mfd sounds very low. Years ago, I rebuilt a pair of these and ran actual curves... I'm sorry, I just don't remember, but It seems to me that it was more like 20 to 40 mfd to correct the impedanc... | |
| Types of speakers to create nightclub style sound? I've done 3 night clubs way back when. In one I did indeed use bag end. They were some of the better sounding drivers that didn't crap all over themselves when pushed. In 2 others, we built the speakers from the place where I worked at the tim... | |
| Can an IC based amp be considered 'high end'? A good friend of mine years ago was Marcof headamps, cartridges, cables, amps etc. He build an amp from STK086 mono amp chips. He did his own circuit design, made and etched his own boards etc. He has a excellent parts on the boards as well as a m... | |
| First order/Time Phase-Coherent speakers discussions @cousinbillyl You are correct about a lot of your phase conversations.... I spoke with Jim years gone by..... you might remember or go find up the thread where I said something like you can get a 1st order down to around a 15 degree phase shift???... | |
| First order/Time Phase-Coherent speakers discussions By the way, to be clear: Absolute phasing is IMPOSSIBLE. You can get phasing done at the crossover point which is the goal. a woofer playing bass at 50 cycles will move at a different rate than a tweeter playing at 15000 cycles. When we align ph... | |
| First order/Time Phase-Coherent speakers discussions " I am still waiting for someone to tell me who can understand time-phase coherent, including all the experts in the world )-: :-("That I can help with....First understand "Time Alignment" The speed of sound moves at the same speed at all freque... | |
| First order/Time Phase-Coherent speakers discussions Andy, you have opinions that you don't understand. I'm happy to stick to your original premise, but slamming others for giving accurate information does not work. You never know, a couple of these guys could be speaker designers and worked with mo... | |
| First order/Time Phase-Coherent speakers discussions Andy, you have shown in your comments that you have a VERY LIMITED KNOWLEDGE. A decent active crossover in knowledgeable hands will crush the performance of a top tier passive crossover. Maybe you should explain what time phase coherence is from y... | |
| First order/Time Phase-Coherent speakers discussions Properly done active should always be better | |
| First order/Time Phase-Coherent speakers discussions you really have a lot of homework left.... you can't figure phasing without understanding the drivers being used and how slopes and parts will affect phasing.... it has not been mentioned, but remember there is acoustic phasing as you have been di... | |
| First order/Time Phase-Coherent speakers discussions @andy2 Not sure that there is a question here. I've run many simulations with 1st, 2nd, 3rd and 4th order slopes. I've run many comparisons with butterworth and linkwitz riley in 2nd and 4th order. Even putting a single cap on a part does n... | |
| SIMPLY AMAZING: Coda Technologies 07x Preamplifier At one time, I owned a Coda CL, it was the linestage version of the current CP. It was excellent in its price point. I have sat in front of the CP on a couple of occasions and the 07x on I believe 4 occasions. These pre's have always been excel... | |
| I'm looking to learn about Air Motion Transformer technology No, I don't need to clutch at the shape of an impedance curve. I clutch at the fact to make an amt, you take ribbon basic design and fold it. I've not argued differences. And once again you turn smart aleck. |
