Wobsbass Posted July 5, 2014 Posted July 5, 2014 Hi all. I'm new to this forum and want to pick your brains. I'm wanting to know if the combo I've just bought is 300 watt at 4 ohms with both speaker jacks used or is it 300 watt at 8 ohm and 580 watt at 4 ohm. Grateful for any guidance. Cheers. Quote
Dad3353 Posted July 6, 2014 Posted July 6, 2014 Good evening, Wobsbass, and ... [URL=http://www.smileyvault.com/][IMG]http://www.smileyvault.com/albums/userpics/14389/tekst_welkom~0.gif[/IMG][/URL] ... to the forum. I'm not familiar with this specific combo, but the 'normal' interpretation would be 300w into a total load of 4 ohms, using both jack sockets. The secondary cab should be 8 ohms; the speakers in the combo are very likely to be a total impedance of 8 ohms. Thus, with the extra cab, the amp 'sees' 4 ohms, and can deliver 300w. Using only the combo speakers (only 1 jack...), the amp can deliver 210w. Hope this helps; subject to completion, correction and/or contradiction from others. Quote
