Default Power Supply for TDA7293

Hello Diyers

I want to build an active 2.1speakers system. Am intending to have three 4ohms drivers (full range, mid range & tweeter) in left speaker cabinet and similarly in the righr, amplifing each driver with a separate TDA7293 amp.

Is it possible to use one power supply, to power the three driver in each cabinet?

Hi. Yes you can use one power supply since the amplifiers require the same voltages. What I don't understand is why you want to use a full range, a mid range and a tweeter.
Is this what you meant, not a woofer instead of the full range?

Thank you Scott

I will have a woofer separately.
Would the use of a full range and midrange be a duplication of resources in such a configuration?

Yep. Three way speakers are usually woofer, midrange and tweeter (WMT). Sometimes they are MTM (technically not 3way), I've yet to hear of a FMT...
