Must’ve been like losing a close friend.
Unfortunately, I don’t have a room in my house with two proper corners.
Having the Ks (or La Scalas) in a room is like having Lana Turner in the room:
The first thing people notice and the last thing they remember.
So either your wife is a body builder, or she had a plan, and help. 
I have a pair of Heresy-like homemade, with a safe WAF.
Way to keep it car-related!
I’m impressed the Advents’ woofer surrounds are still working. Then ones on my JBL L100 went away years ago.
I have Advents -large and a Marantz receiver. The tweeters are fine, I had the woofers re coned. Great sound.
I have a pair of Acoustic Research AR 2ax speakers. However, the rheostats that control the midrange and tweeters are defective. I bought the speakers back in 1965. I was at a local music store one day buying valve oil for my horn and the store had a pair of Polk Audio speakers someone had traded in for more expensive speakers. I bought the pair for $65 and thought I would use them until I had time to repair the Acoustic Research speakers. The Polk speakers have reasonable sound reproduction, so I never got around to repairing the Acoustic Research speakers and now wonder if it is even worth the effort.
I thought about buying new equipment, but I just spent $6000 on a horn that I really liked.
Related to the indirectly car related OP.
Yeah the guy was playing music too loud, but ultimately so what? He’s in his space, in whatever mood; maybe it could be seen as rude.
What you did though, was escalate that to a confrontation. Directly and challengingly. As you point out you were prepared & ready for your comment to require a follow-up “decking”.
His bad, but yep, your bad. I’d say your approach maybe was worse considering your intent to follow up.
A great example, for attitude, is to look at the world through a flight attendants eyes and dealing with issues on board, in a tube of anxiety with hundreds of stakeholders - Who cares who is at fault? Ultimately it’s irrelevant to outcome. There are only 3 goals: de-escalate, de-escalate, de-escalate.
Do you use dino oil or synthetic for your horn?
You have to understand it’s a cultural thing and a matter of courtesy when you live in a group. In some cultures you keep a 4 foot distance speaking to people so as not to invade their comfort zone. In others, they stand about a foot away. I’ve got a friend that is not from around here and I have to keep backing up so I don’t get spit on. In some cultures they parade their cars proudly with loud music. It’s just a matter of courtesy to those that may be around them. Same thing with loud mufflers.
@old_mopar_guy I use synthetic made by Hettman. I use a heavier viscosity for the valve bearings and a lighter viscosity which I pour 3 drops down the valve tubes after removing the tuning slides.
Before the synthetic oil became available, I used dino rotor oil on the top bearings and used it directly down the tubes into the valves and for the lower bearings I used sewing machine oil.
Any one remember EPI’s? never had any except after a 10 hour drive 
Totally understand that Bing, perhaps I misworded it. The important thing is that fault doesn’t justify all actions. Two wrongs really do not make a right.
I know the American legal system and such cultural interactions seem to pivot entirely on fault and blame - that “someone else caused this!” But it’s not justification for action when no one is really hurt.
Unfortunately someone or several people could have been hurt here simply because 2 “cultural” or social groups crossed in a somewhat neutral area and someone chose to take offence as offense.
But they do make it even. 
Those are HUGE speakers. About 20 years ago my wife complained about my Altec Model-15 speakers. They were so big. She wanted me to get skinnier speakers. So I replaced them with a custom made taller skinnier speaker with the Great Plains Audio (Altec 604 speaker) similar to these. They were skinnier (by about 2")…but also a lot taller. Wife grudgingly agreed.
KA-601 integrated amp (Kenwood). It’s a replacement for the original Dynaco amp I assembled when I bought the speakers. I still have the Dynaco FM tuner.
I’ve always been a tube guy (except in the tires on my car).
My amp is Tubes. It was a kit from Cary Audio (no longer made) using the WE 300B. You need speakers like the Klipschorns if you have tube amps. Those speakers have about 105db efficiency.
