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,

If you loved the sound of these speakers what were you trying to achieve with this crossover??  I can perfectly understand replacing the stock crossover with higher quality caps, coils, and resistors.  But did you give him license to rework the crossover??  That seems like a roll of the dice if so.  Did you contact this individual and voice your displeasure?  It would be fairly easy in some cases to adjust the resistor values and increase the tweeter output to its original level.  Curious how you connected with this "expert."  There are a few talented people out there that do this type of work.  These people also have many reviews from satisfied customers.
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
