Shunting Bass out of Horn Amplifer ? ......Bert ? (BD-Design)

Hi Kevin,

Have you heard of this? --- What do you think?

Yes, true but ...

Depending on the used amplifier you can or you shouldn't. If your main amp is capable to give good bass signals without noise (without the need for much power) then your present connections are optimal.

This way you keep the harmonic signature of the sound fed into the bass system the same for optimal sounding integration.

If your main amp is not capable (makes too much noise or uses relative small output transformers then it can be beter to use a pre-amplifier or split the signal on the input of your main amplifer and connect from there to your bass amplifier. Make sure that the input impedance of both amps are not too low, your source might not be able to drive this load if it has a relative high output impedance (TVC's do not like this at all!).

As long as the output impedance is roughly 10 times lower then the combined input impedance then you're good to go. A pre-amplifier with output a buffer or 2 buffered outputs work best.

Hope this helps.
