Hello,

I am hoping the experts here can help. I have a pari of A5's 16Ohm (Hiraga type crossover). My tube amp has 4 and 8 ohm.

Does it bennefit the sonics for me to get a pair of zeroformers to reduce the impediance from my speakers to 8 ohm?

The zeroformers are generally used to multiply the impediance and do not know if using it to devide the impedance would make any positive

difference top the sound.

Thanks!!

(1) P = U * I
(2) U = R * I ->
(2a) I = U / R -> substituted into (1) ->
(1a) P = U**2 / R

Power will be halved, which is a loss of 3 dB.

Sonics will not be affected. The speaker simply draws less current.
