Surely a different Paul Barker

Ah, 20 cars makes more sense. Thanks Nick

There must be a true RMS vs PMPO thing going on here: 600V x 500A is only two cars

Toccata and Fugue on a variety of instruments. First one is amazing

With the IKEA ones, I couldn’t glue them together because of whatever they were coated with. I taped a sheet of sandpaper to the floor and put the bowls upside down on it then rubbed them until I had a flat on the rim. Glued easily with pva then Don’t know what the Wiko bowls are coated with, but I ...

Ray, what about something like this: https://ikeahackers.net/wp-content/uploads/2022/06/spherical-ball-speaker-diy.png If I was still making speaker I might be tempted to build a similar pair. 8) I have wondered about those, but the centre to centre distance looks too big to me. Wonder if they coul...

Sounds like a good plan
Looking forward to the tweeter - not seen one like that before

Very nice That 60Hz is going to be fun to fill in Do you know where it is coming from? I have similar on my left speaker as there’s a bay window at that side - the other side is open to the dining room, so I don’t have it on the right speaker You have it on both speakers even though your room isn’t ...

I assume that ICE cars are shipped with empty fuel tanks, couldn’t they ship electric cars with flat batteries?

Good job it is a hypothetical speaker and nobody is building it then
Seriously though, many small bookshelf speakers are tuned to around 70Hz, so not ridiculous, unless, like you said, you like bass

I have a LR4 high-pass at 45Hz just to be safe
SWMBO likes karaoke with her friends, and you only need to drop a microphone once…

I think whether room or speaker dominates depends on their relative frequencies. My living room has a strong peak at 50Hz, a large dip at 40Hz, and there’s a big suck out on the left speaker at 70Hz. A bass reflex cabinet tuned to 80Hz would be speaker dependent, below that, the room definitely domi...

I guess we would have to put all of the large excursion Thiele-Small parameters in WinISD or similar to know the total effect

Not exactly. You're in the acceleration (rising response) region here, where as noted you can and do get variations with drive level due to the electrical & mechanical non-linearities / asymmetries in motor design, suspension[s] etc. Klippel is very good at revealing the reasons for those, but ...
