16A redux


What’s the efficiency of the drivers+horn? And unless you’ve done some foo to the 6EM7 you’ll be getting 2watts with a following wind.


About 108dB/1W


Christ. I thought I was doing well with 101 FFS



It’s probably drivable with an iPhone.


That’s why I got Andy to double my output so I have a ginormous 8 watt :wink:



Lol, I’d be fine with 0.5W.

8W is about right oiff 101dB/1W speakers


I heard a dem of some Westminsters about 30 years ago where the salesman used a preamp only. Proved the point.


Perfect. :smile:
