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

You might reach out to Danny (GR Research). He improves a lot of speaker XOs. Send him a couple pictures

Contact the expert who did the crossover and tell him what you're hearing.

$2K sounds like an "expert" in the confidence racket.

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?

Some good suggestions; 1) Contact the expert and describe your issues. Crossovers don't need burn-in to sound good, just get better. 2) Good suggestion mijostyn, maybe error. My thought; Hope the original iron core inductors were not replaced with air cores, especially for the low frequency drivers. Iron is usually better than air for woofers. Ask "expert" for a detailed schematic for the crossovers he made for you.
