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.

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...

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.

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...

Sounds like a leaky cap.  Get it looked at before you blow your output stage transistors.  
Speakers replace or improve?
Hey OP, For a modest apartment you should have as much bass as you need, and indeed it sounds like you can get it, you are just afraid of the neighbors. Check out the AM Acoustics room mode simulator and try to keep your speakers and listening l...

OP: And I told you not to claim you had no bass problems until we got to them... 😂 Once you get your woofers pumping we may have to revisit that issue.   
Any one measured the EMI/RFI attenuation performance of audiophile power conditioners?
Want to point out that series mode power conditioners are essentially low pass filters that start working ~ 3 kHz. True for ZeroSurge and Furman with SMP while AFAIK, RFI filters usually start in the 10s of kilohertz. This is why I always recommen... 
Room Acoustics, minimal treatment and measurements
OP: First, you are going to be very glad of the treatment, but now that I see the measurements and the specs, I think your woofers are not working at all.  You may be missing the straps that connect the woofer to the 7" drivers. Based on specs, ...
