Well, that was a blast from the past!
It is funny how the whole concept of "retro" works, isn't it? That something "old" can somehow be "new" and relevant and desirable.
I do think it's very brave of you to not only review something like this, which is probably niche at best, but enjoy and celebrate it too. And when it comes to speakers, yes, size does matter, even with the sonic compromises that can accompany this.
And if a picture can say a thousand words, your first image in the review of the PMC on top of the Beast pretty much says it all - this is what you are getting and this is what you can expect.
I would suggest that these are designed for a more relaxing listen, not for anything too hard-driving or busy, and also someone of a certain demographic maybe? My only criticism is its appellation - I thought it was a 15" driver, not a 12", as that's how most manufacturers tend to identify their speakers.
Regardless, even though I would never buy a pair of speakers like these, I'm still very glad they exist.
