Sorry, one of the amps here is a Tube type, rated 15 Watts. If I understand correctly, one requires more than 15 Watts at the speaker side of things, that is why I am looking at more power. It does switch to 5 Watts, but really, why bother? Currently running a 10-30 with it, how long before the speaker is "run in"? I have an A-type on hand for that amp, but may never (?) (soon) need to build that cabinet. I do believe the A-type will give a fuller sound, so, it is a definite project. Hmm, and the never-ending spiral to more Tubes, maybe I actually really need that 18 Watt tube amp?
Hah, 200 W speaker on a small amp? I have read somewhere that the response curves and dB rating is done at 1 Watt? Bear in mind that you do not often (well, I do not) pump up the Hi-Fi to Flying Squad Intervention levels, and normally (?) listen a reasonably low levels, and still expect good sound. Thus 150 W speaker at 2 Watt. Good to go. OK, better at 10 Watt. Room too small. Would really like a 15 Watt tube amp....
Aside, I have listened to a Macintosh amp, with big, giant B&O speakers, for that room, 5 Watts were plenty. Good at 15 Watt. Many Watts available, to drive Bass. Which we as guitar players do not have. Any electrostatic "bedroom" guitar amp-speakers out there?
