Personally I don't use MDF all that much....makes great countertops, though.
I'd like to think that most of what's occurring here is 'relatively' good-natured teasing over each other's foibles...hopefully, preferably...
I mean, Everyone has a pair...
(Speakers...stop that...)
Own as many as you want...in any flavour, size, response, cost. If a Casio cuts the cadence for you, Kewl.
Hire a hall, and invite 50 of them....someone on eBay was selling an enormous 'wall full' of JBL's that would need a ton of amps...and that potentially could be all class D's....
If K has 'mystery' units, fine. If they curl his toes, wonderful.
But, it does answer the 'original query': Yes, he does.
All gawds' chilllin' gots speakers.
Ok, settled. Now, let's argue about....cables! Yeah! That's always good for about....*mmmm*....30 odd pages...and I do mean odd....;)
(I'll stop ranting now....)
