Well... those posts are 20 years old, but may help someone.

a little late to the party, nice day for yardwork up here   Regarding the tweeter, I have one poly, two phenolic and one titanium diaphragm I just hooked up to the meter. It looks like 8.5 is an average reading between the lot.    Parts Express has the polyswitches for peanuts, and if you are in the States the Crites and SimplySpeakers titanium diaphragms are free shipping (over $50). SimplySpeakers looks to have a phenolic “style” replacement too but they are not original equipment. I really liked the titanium TWEETER diaphragms, some don’t, so do your research on those.    I recently put the phenolics back in the 301s to sell them and did not find anything immediately lacking in their presentation, they just sound better to me with Ti diaphragms. They sounded even better with Dave A’s LMAHL with the DE-120s, the same lens with the DE-10s needed a little attenuation, to my ears.    If you are going to replace one, you may as well get a matching pair and have a spare, that you’ll never use, lol.   When you get them up to snuff be sure and let us know your impressions.   Cheers,    

My cinema 600 lost power as well,  it's out of warranty , so I purchased the above power supply listed in the link.  I see the Pic from the original soundbar power supply does anyone have a Pic of the new power supply wired?

You get what you pay for! These networks are fantastic and if I was not selling my LSs, they would be staying put right here.   Dean, I sent you an email with a question a perspective buyer has regarding compatibility.

I assume it's all 4 for $1800.00, but you'd have to message the seller to find out. https://www.facebook.com/share/WJ68XXBz7CviMCNn/?mibextid=kL3p88

You could tri-amp them with an active crossover. Then it wouldn't matter what impedance your drivers are and you can control the SPL of each driver to your preference. Just another option    

My mistake- my apologies to you!  

It wasn’t sarcasm, I just didn’t understand.
