| Should Amps be plugged into a power conditioner? Hey @geof3 - I’ve researched and written on the subject of whole-house vs. point of use surge protectors. TL;DR - Keep your point of use protectors even after getting a whole house unit, the main reason is the high (~ 600V) let-through voltages m... | |
| Should Amps be plugged into a power conditioner? The main reason I don't think amps should ever be plugged into a power conditioner is that I enjoy having them repaired after lightning strikes. Packing up my 60 to 150 lb. beast, putting in the car, paying for shipping, waiting on the techs to d... | |
| Room Acoustics, minimal treatment and measurements That’s really quite good, but seriously what are the woofers doing? I'd expect at least a 3-6 dB boost when they were engaged. | |
| Room Acoustics, minimal treatment and measurements @erik_squires Yea I’ll do a sweep to see that potential dip. Are you thinking there’s some frequency cancelling happening or a cross-over issue? If there is no bass to mid-bass crossover, then I expect destructive interference (frequency dips) ... | |
| Room Acoustics, minimal treatment and measurements OP: To confirm what I thought I read in the polish site, can you measure the frequency response for 1 speaker 45 degrees off axis? 1 to 2 meters away (3 to 6’) is fine. I want to see if there’s a major dip there. If you see a big dip, unplug the... | |
| Room Acoustics, minimal treatment and measurements If this was my system, I'd bi-amp, using a miniDSP as an active crossover in front of the amps. It sounds really good. This is going to give you the ability to properly high pass the mid-woofers, low pass the woofers, which will improve off-axis... | |
| Room Acoustics, minimal treatment and measurements I was wrong btw, I found I think a polish sight that says the min impedance is 4 Ohms, but still, with bi-amping you can set levels independently. The site also noted poor off-axis integration, a potential sign of the effects of the overlapping ... | |
| Loud pop/screech when powering on amp Sorry my friend but I have no idea. Call a local stereo shop, if you can find one. | |
| Room Acoustics, minimal treatment and measurements Normally, I say to leave a speaker be and not to try to hack it very much. Either love it as is or get something else. In this case though I feel you have a number of approaches which could be really worthwhile for you and your dad. Compared to... | |
| Room Acoustics, minimal treatment and measurements I found the Stereophile measurements for the predecessor. If the two units are similar, then your measurements are actually quite normal for the line. The review also goes into some details about the unique crossover choices, which your measuremen... | |
| Amps Recapping Sorry I should have added more detail. Take the cover off and look for signs of corrosion/leaking around the electrolytic caps, or signs of bulging. Caps made in 2000 or later have a much better reliability in terms of aging on the shelf than ... | |
| Room Acoustics, minimal treatment and measurements OP: Maaaaaybe? It could be as simple as your speaker cables are not hooked up right at the amp or that the ends of the bi-wire cable are swapped somewhere. That's the bi-wiring aspect of this complicates things. It's worth getting some plain zi... | |
| Amps Recapping Take a look. The usual recommendation, and it's a good one, is to use a variac to bring it online the first time. | |
| Room Acoustics, minimal treatment and measurements SO, yes, straps and cables are fine, but you can do some more basic tests first. Since you are bi-wiring it’s quite possible your problem is one speaker or woofer section is wired out of phase with the other. Check for that before attaching strap... | |
| Loud pop/screech when powering on amp Sounds like a leaky cap. Get it looked at before you blow your output stage transistors. |
