In Reply to: V. Khomenko speaker rec. for BAT VX3i and 55 amp... posted by M. Vidal on March 5, 2007 at 05:47:11:
It is hard to recommend any specific model or brand, as there are so many fine ones out there, but generally speaking something in the 90dB range, with more or less flat impedance curve would be right load for the amp. It can actually drive the demanding speakers too (depending upon the desired volume), but with some deficiencies like you pointed out.
Follow Ups:
Victor, with a push-pull tube amp, are the impedance peaks in the bass region (arising from system resonance) detrimental? My impression is that tube amps are more likely to be unfazed by bass region impedance peaks, whereas a solid state amp (acting as a voltage source) will have a power output dip where the impedance peaks.But then, I don't have an engineering background and have never designed an amplifier.
Thanks for any light you can shine in this direction.
I don't see any danger to impedance peaks. The 55 is not a typical pp amp. For instance, you can run it with no load connected forever - it doesn't mind open circuit.
Thank you!
When you find a pair of speakers with "more or less flat impedance curve" - please let me know...
Without going too far, the Dunlavy's are like that. No longer fashionable, hence inexpensive, but VERY good.
I did not have a lot of experience with those, but did not care too much for SC-5s. Maybe they look good to an amplifier, but they sound like... well, I guess I should stop here.
There are some things the speakers like the SC-IV could do that no other speaker can do even today. I still regret getting rid of them - about best orchestral music reproduction I have ever heard.
I am not a big fan of one-box full-range solutions. On a different subject - what software could you recommend for drawing schematics?
Hard to recommend anything without knowing your particular needs. Any electronic CAD software will let you do it, plus any of the common drawing packages. If you then want to analyze your schematics, then you need something integrated with the simulator, but it doesn't sound that is what you are asking?
No, I just need the drawing part. "Karandash" - is that the name of the program?
No, it was just a joke...Since you don't need anything fancy, maybe the best way would be to post this question on the DIY forum, they would probably have good recommendations for inexpensive packages.
Or you could go to http://www.spectrum-soft.com/index.shtm and download their demo version - it will actually do all you need plus whole lot more. In fact most CAD vendors have demo versions available. The trick is to find the one that allows you to save the drawing, and I believe the Spectrum does that.
Evaluation seems to do a lot, though it is limited to 50 components, damn it... And the price is so high! $4495! They are nuts. But thank you.
