Problem Solvers Needed-Got my New XOs installed and am worried....


I think I made a big mistake. I loved the sound of my 1988 Tannoy FSM Dual concentric 15'
speakers. So I thought an expert could analyze the existing XOs and make improvements.
I installed the new XOs expecting a 300-400 hour burn in period. Herein lies the problem.

After 30 hours or so the initial sound has no high end to it. I expected to initially hear sound as good as I had
which would continue to improve as the burn in continued. But no. 

I am tempted to reinstall the old XO and kiss off the $2k invested. 

I am very open to some suggestions from anyone who has been down this road.

Thanks,

chorus, Make sure they are hooked up correctly. Without speaker impedances and the values of the components it is impossible to make an accurate statement. Somebody may have goofed up on his math. I would put the old ones back in for the time being. Draw a schematic of the new crossovers with the impedance of the speakers and I'd be happy to run the math for you. You may be able to adjust a value or two and get the right result.  
You might reach out to Danny (GR Research). He improves a lot of speaker XOs. Send him a couple pictures

Are the tweeters connected? is any sound coming out of them? Did you make a mistake in installing networks? Did the new xover factor in insertion losses?
