Chipamp for super tweeter.

e679 · 1st July 2009, 05:32 PM

I would like to build chip amp for my tweeter (can good up to 45k flat) , active crossover around 7k~10k .
Anyone knows any chip amp can have flat response up to......... over 100k with sweet/smooth sound? Lots of air?

Will gainclone let's say LM3875 able to do so.

many thx

One problem though: Nobody has heard sweet tones at 100 kHz.

The best tweeter i have heard is Acapella Plasma tweeter.
Oh man, they are sweet.....

I am using Pass's Zen amp for my TAD et-703, it is sweet (class A) but it's role off too much too early.

I am wondering if anyone knows a T2024 or Lm3875 amp can beat it for tweeter only.

which rolls off too early?
The tweeter or the amp?
I can't believe one of Pass' Zen amps rolls off too early. Some go out to half a MegaHertz.

Use ADSL line drivers - they're good up into the low MHz.
