I just acquired a late 2014 1.4 GHz Mac Mini and am using it for tv mainly in my workshop. I have lots of speakers and amps I could hook up for audio, but was wondering if anyone had tried hooking a decent external speaker to the built-in audio amp? I have found that for speech mono is clearer than stereo. I've been in the pro (if you can call it that) audio field for about 50 years and have high end recording gear. I remember once in the 80's hooking a tiny Radio Shack transistor radio up to a big JBL speaker (15" woofer, 8" mid speaker and horn) and was amazed by how good it sounded. It didn't sound that different from a pro quality pa power amp at low volume! That made me realize that the speaker and cabinet are extremely important. I haven't been able to find out what the output of the built-in audio amp is, does anybody know? With a playback system you have an amp, a speaker and the speaker box. I can tell by the sound of the Mini that the amp is not bad, the speaker is utter garbage and the speaker box, well, er, it oddly sounds like a tiny metal box... I've had several small tv's where i put a switched jack on the side that was hooked up to an internal speaker. The sound quality was improved a billion percent. If anyone has done this or has any idea about the amp's output (guess would be 10W into 8Ω) please post your comments.
