I'm glad to read some are listening to older speaker designs. Audiophiles would serve their ears well by going back as much as going forward. Personally I'm not nearly as fond of some of the newer designs vs designs that are listener based. Speaking for myself, I much prefer starting with drivers that are basic in design. This means (most of the time) the vibratory value is wide as compared to starting with something that is stuck in a fixed signature that needs to be corrected elsewhere.
Give a look to how the driver industry is making their way back to some of the old school basket designs for example. There for a period of time drivers were pretty poor, and very expensive, frankly they were way over built and only sounded good in a few limited situations. People should keep in mind that a complicated crossover means that the drivers are having problems that need to be addressed.
I have a simple formula that makes the hobby easy for me. Tune the recorded code to the audio code, along the audio chain, all the way to the room and ears. Two things you will notice. One every listener will have a different setting to their system compared to anyone else. And second, when a recording does not sound right to you, you can variably tune it in to your liking.
have a great weekend
