catmanhog Posted July 12, 2011 Share Posted July 12, 2011 Apologies if this has already been covered but the site isn't letting me search.. I have a Five Fifteen combo & I'm considering using the extension facility on it - anyone out there done this? What are the pro & cons with this? Thanks, Sean Quote Link to comment Share on other sites More sharing options...
xgsjx Posted July 12, 2011 Share Posted July 12, 2011 Add another 1x15 cab (make sure it's 8 ohm & try & get the matching one). Pros = more sound Easier to hear yourself Cons = more to carry I think the pros outwiegh the cons Quote Link to comment Share on other sites More sharing options...
RandomBass Posted July 12, 2011 Share Posted July 12, 2011 Hi I just had a nose at the manual on Ashdown's website, and I found this paragraph: EXTERNAL SPEAKER – An External Speaker socket is provided to allow you to use an external speaker cabinet if required. This cuts out the main speaker when a jack plug is inserted. The external speaker must be a minimum impedance of 8 Ohms for the After Eight and Perfect Ten but can be 4 Ohms for the MiniRig and Five Fifteen. Now I find that unusual - the external speaker effectively replaces the internal one, as opposed to supplementing it as with other combos (my old Ashdown EB180 springs to mind). In my rather limited experience of combos, the amp is usually rated at a certain number of watts into 4 Ohms, but the internal speaker is 8 Ohms - so adding another 8 Ohm extension cab (as opposed to 'external'?) gives you the full wattage at 4 Ohms. So unless you have more speaker area, or more sensitive ones, I would guess that an external speaker might not add much more volume wise.

xgsjx Posted July 12, 2011 Share Posted July 12, 2011 That's a bit pointless! Though if the 515 is a min 4Ω load, you could use 2 8Ω cabs (but isn't that the point of adding an ext cab?). Quote Link to comment Share on other sites More sharing options...

Blademan_98 Posted July 12, 2011 Share Posted July 12, 2011 My Orange Crush 50w is the same. Plug in an external cab and the internal speaker goes down. Plug in a 1 x 15 (as I do) and the sound is a lot deeper Not worth lugging to a gig, just use the line out and go through the PA. Quote Link to comment Share on other sites More sharing options...
Ed_S Posted July 13, 2011 Share Posted July 13, 2011 If it was mine I'd get in there and check the impedance of the internal speaker. If it happened to be 8ohm then I'd safely disconnect the internal speaker, solder a new speaker lead onto it and run it outside the combo to a jack. That way it'd plug into the external speaker-out when flying solo, and could be plugged into the parallel out of a suitable extension cab to run both together.
