BEC Crossover Rebuild

No don't have any problem with not having any sheilding between speaker and TV. Pic looks great as always. I think as long as the tv is not close to the magnet on the bass bin it is okay. On other tvs it may cause problems. There is about a inch of pine between the speaker and tv so maybe that is enough to block it.

No gaussing problem on the TV with it that close to the La Scala?

Twenty-some years ago, at university and living at my parent's, I

bought a 14-inch TV and put it next to my work table which sat between

my La Scala's. After a few weeks, the colors became way off

and distorted. I called up the store and they sent a tech, who

degaussed it and asked if that was a speaker the TV was sitting

on. Yup, the La Scala was causing the problem; probably the

mid-horn driver. How stupid of me not to think of it!

Another thing I noticed last night is that it seems

to be louder. Is this common with crossover rebuilds or am I imagining

things?

Since I'm in Canada, it wasn't economical to ship my boards to

Bob. So I ordered caps and replaced them myself. I too have

the strange impression that it's louder, but quite a bit. Maybe

the clarity means I'm just pushing less to get the sound I want.

I used to listen to a certain Diana Krall CD at -30 dB on the

receiver and didn't feel I needed nor wanted to go over -40 dB last

night after the caps upgrade. (I

regret not taking out the SPL meter before the upgrade to measure a

reference). Sibilance didn't bother me before and now I notice it

more. I may have to put the old caps back in! [;)]

More evidence that the speakers have more highs after the caps

upgrade. I have two external amps which I can use. A Nikko

Alpha 220 which made no more of a hiss than my receiver, and a carver

M4.0t which had a very audible hiss when connected. The Carver is

now almost unbearable and I can now notice a hiss from the Nikko

Alpha. So definately more high frequency content grtting through

now! I'll have to do the same upgrade on my La Scala's now!
