Weird but very good sounding American speakers,....What is inside this speaker?

Conclusion: When you buy a second hand Ohm model F speaker with the original Walsh drivers it will cost you a extra $2800 for a upgrade. When you buy a second hand Ohm model F with a older upgrade(like the speakers I have) you can easy buy these speakers because the only thing what can happen is that you need new foam rings ore tweeter replacement what you can do local for a lesser amount.
The speakers sound fantastic but you need a big room what can handle the bass.
