Monacor MZF-8633

I'm losing interest in expensive active speakers, so I make my own passives now, they're much bigger, but give much more sound from much lower powered amplifiers.
I also have much more control of my "treble, mid & bass, simply by tweeking my active crossover, no passive losses.
These speaker grilles are the perfect finishing touches to my speaker boxes. I hope Thomann keep them coming.
BUT! these grilles resonate at unbelievable volume when in use. Not good at all, killing your fave bass lines dead, OK @ 50 Watts, but at anything above, completely overpowers at a large part of the frequency range.
