[quote name='Mr. Foxen' post='874409' date='Jun 22 2010, 01:57 PM']Why does it have to be 4 ohm? You are going to be sacrificing a fair bit for that, and since I am fairly sure you are all valve amp, there isn't a power loss issue. If it is for chaining multiple cabs, are you stuck with the old 'no 16 ohm tap' issue? Maybe a series/paralell switch to match it would be the way, since you have pretty limited options for 4ohm drivers.[/quote]
Ideally I want to run it with my 8ohm 4x10 (ontop) meaning a 4 ohm load or a 16ohm load meaning it works with all my amps.
This ohmage also means I can mix and match my cabs a fair bit between all the amps.
Might just forget the idea and get another 2x12 made.
