| Sloped baffle Ngjockey ... I concur with your take on the S5 stats and build quality. As far as the X-over is concerned, not sure what you mean by unobtrusive, but I'd be willing to bet we're talking about 2nd and 3rd order X-overs here. Fyi, I traded e mails w... | |
| Sloped baffle Thanks again Bombaywalla. I caught the article. It doesn't speak to the impact of the speaker's electrical characteristics on phase coherence. Maybe it's just a non-issue.@Tim ... based on the various posts in this thread, I gather there are not v... | |
| Sloped baffle Bombaywalla, yes, your post is responsive and I get it. I still wonder out loud whether speaker inductance as a function of frequency response in fact remains constant within the speaker's pass band. Indeed ... even if speaker inductance remains c... | |
| Sloped baffle Bombaywalla, I reread Roy's White Papers. He speaks to time and phase effects caused by speaker cone mass, suspension elasticity and damping. Nothing about phase shifting (if any) that may be caused by the inductive reactance of the driver itself,... | |
| Sloped baffle Thanks Bombaywalla. I read Roy's White Paper, but will re-read the sections you suggested. Meanwhile, I just checked Stereophile's bench test report of the Maggie 3.5R and see that it is not time coherent. In fact, JA speculated that the midrange ... | |
| Sloped baffle @Ngjockey ... let me try to unpack what you just wrote. Let's assume we have a single dynamic cone speaker with a pass band of 35Hz to 20K Hz. Let's forget about high frequency beaming and cone breakup. Just assume this hypothetical speaker has a ... | |
| New VPI 3D Arm Hiendmuse ... your last post makes me happy. The folks at VPI are good people. Sometimes their bent on innovation gets in the way of taking care of the little things that make such a difference. | |
| New VPI 3D Arm I happen to be a big fan of VPI. I own a hot-rodded basic Classic with a Classic 3 base and early version Classic 3 SS wand. Yes, ... I ordered a new azimuth ring because the stock ring didn't clear the VTA tower, but that's on me because the Clas... | |
| Sloped baffle @Nrenter ... you make a fair point. My non-techie surmise that the "non-linearity" you described is the reason why manufacturers use multiple drivers. I suspect that in making design trade-offs, the characteristics of the particular driver are cho... | |
| Sloped baffle Lewinski... great post. I was impressed by the various digital analyses and corrections that the software was able to effect. Hopefully, speaker manufacturers will be able to achieve greater time and phase alignment, driver linearity and low disto... | |
| Synergy Between Magicos5 With Pass Labs X350.5 I've been toying with the idea of changing out my speakers, Paradigm S8s (v3), for Magico S3s or S5s. FWIW, I had a long conversation with a Magico tech guy about a month ago about whether my amp, an ARC Ref 150 (150 wpc), has enough juice for the... | |
| Sloped baffle Bombaywalla, please list the major speaker brands that are time and phase coherent. At this point, I am aware of three brands: Vandersteen, Thiel and GMA. Are there others?The reason I ask is because I'd like to check area dealers who sell time an... | |
| New KT150 tubes? Xumbug .... as a general matter, I would be remiss to advise fellow ARC owners to drop KT-150s into their amps unless ARC said it was ok. Much of the discussion in this thread pertains to dropping KT-150s into current vintage ARC Ref amps, namely ... | |
| New KT150 tubes? Djcxxx .... one other issue comes to mind. I'm thinking about resale issues. If I was interested in buying a preowned ARC amp, I would ask the owner if he rolled the KT-150s. All things being equal, if I could buy the same model, sans KT-150, I li... | |
| 4 ohm taps on an 8 ohm speaker Right on Al. Actually, what I had in mind was a speaker with low'ish impedance in the bass/lower midrange frequencies, with a peak at the mid/tweeter crossover point. As I'm sure most would agree, matching a high'ish output impedance tube amp to t... |
