external power supply question, will it work?? You need voltage AND current. However, the problem is finding a high quality, low noise unit. You can find several wall warts which are digital and noisy as can be. I can highly recommend Astron power supplies as great, low noise, general purpose ... | |
Increase total Speaker Impedance -- Potential Solution What exactly are you trying to do? If you add anything in series you can alter the impedance, but you also lower the output. The question really is WHY. Best,E | |
The invention of measurements and perception @erik_squires, since you are a teacher of experimental psychology Ahem ... no no no, that was not me! :) @edstrelow This is attempted, but the measurement is not standardized. I routinely see Stereophile publish measurements from an acceleromet... | |
Back to the drawing board I can highly recommend GIK Soffit traps below 100 Hz. Traps don't have to remove a mode entirely, just help drain the energy, then an EQ can take over. So, a partial solution, that is aesthetically pleasing, can do the trick. | |
Back to the drawing board I don’t know if people realize just how BAD room modes below 100 Hz can be.I’ve measured +- 20 dB in extremely narrow bands. That’s about 100x the power output. With output variations like this it is impossible to get the bass to integrate with th... | |
Back to the drawing board Also, sometimes after getting good room treatment you may want a sub less. This can really open up the sound and make the bass feel much deeper. | |
Back to the drawing board It's a shame this is so hard. The biggest issues in my mind with subs are getting the EQ right. Below 100 Hz are where the monsters of audio are. Smaller subs avoid this just because they are smaller subs. Lots of subs built-in auto-EQ / room corr... | |

Hihat Question One quick test you should do is sit about 1-2 feet away from your speakers. Can you hear the balance improve? If the answer is yes, then you need better room acoustics. If the answer is no, then your speakers to source are to blame. | |
Hihat Question Dude, how about the tone controls on your integrated?? | |
Going to try digital Do you need to rip music, or are you just going to stream? Is your house iPad or Android ? | |
Tweeter Capacitor Upgrade (Coincident PREs) Hey @beetlemaniaThe CMR are excellent caps as mains, but above 4.7uF or so they need bypass caps. Below this, I can’t hear any benefit at all. The CMRs are really excellent caps. My main speakers use a 3rd order hi-pass filter. To my ears, bypassi... | |
Tweeter Capacitor Upgrade (Coincident PREs) You'll be fine. Just don't solder too close to the cap body. | |
The Future of Audio Amplification Zero-feedback Class D would seem to be a unique twist.It would, since feedback is how the switching is controlled, without feedback, there can be no switching. The Technics model is different though. It uses digital signal processing to compensat... | |
The cast of JassFM 91 / Toronto started a new gig! Are you in Toronto? Nope. You are aware of allegations of workplace bullying and sexual harassment that led to an exodus of several staff? I had no idea. One of the leaders of Jazz Cast alluded to the change in atmosphere, but no, nothing like t... |
