Ashdown 515 external speaker

[DaniHell6]

Hi!I just bought the ahdown 515 amp (100w rms) but it has not the power I thought it had.:scowl: With the drums and guitar playing, you can't hear the bass. As it has an entry for an extra speaker, I wonder if someone can tell me what speaker should I use.

Thanks!

That will depend on 1) the impedance of the internal spkr, and 2) the size of the internal spkr., as well as the amp's minimum impedance rating. Find all that out first.

The specifications are:

Power Output (RMS) 100W
Speaker Configuration 1 x 15"
Line Input Impedance 1M Ohm, Input range100mV to 10V

As soon as I plug an extension cab into the Ext Speaker socket it will cut out the internal speaker?

In the Five fifteen manual it says:

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.
