these medium-sized towers sound, in a word, right

No way, not with those measurements.

So they don't/can't sound "right" because of the measurements? Oh here we go again.

That's being diplomatic.

...jacket material to cover your speaker cable, or adding an Ikea cutting board under each of your components makes a difference to the sound of your system, then building and "tuning" your speaker like a musical instrument makes sense, too.

I find Alta audio speakers to sound very good at shows also. Maybe it's better not to know how something measures if you like the sound?

This level of piss-poor engineering wouldn't be acceptable on a $300 pair of speakers. What a joke. I suggest the reviewer listen to music on actual high fidelity speakers to calibrate what good sound actually is. Good grief.
