If you are uncertain about your future needs, always go with the 8 Ohm
speaker option so that you can add another speaker later if you need to. In
general, adding more speakers will give you a greater volume increase than
adding a few more watts.
We have designed our amplifiers to operate safely at 2 Ohms only because
everyone else is doing it and some users expect it. However, we much prefer
operating at 8 or 4 Ohms because of the markedly improved quality of tone
and dynamic response. But if you really want to, you can operate your Metro
combo at 2 Ohms without worry.
Two speaker systems we strongly recommend are an 8 Ohm D-210XLT and
a 4 Ohm D-410XLT. With either cabinet – or both! – connected to your
DC210XLT, each individual driver will receive approximately the same
amount of power. This results in very smooth and satisfying sound. By
adding both cabinets (or, alternatively, three D-210XLTs) you can create a
rig that is extremely flexible; you can add as many speakers as needed for a
particular application.
Power Handling – Your speaker system can be damaged by too much or
too little amplifier power. While the amount of amplifier power reflects the
potential for damage, how that power is used (your playing style) is the
critical variable. Too small an amplifier, when pushed to its limit too often,
can generate excessive clipping. This can generate a signal with enough
extra high frequency distortion to eventfully overheat and burn up a voice
coil. Too large an amplifier, when pushed near its limit, can push the speaker
beyond its physical limits. Your playing style determines how much
headroom (reserve amplifier power needed to handle short bursts of sound)
you will need.
Slap style playing is particularly demanding, as short bursts of low
frequency information require a great deal of power to be produced
accurately without distortion. You should choose an amplifier that delivers
adequate power for your playing style without frequent clipping and without
exceeding the cabinet’s power handling maximum during normal usage. It is
OK to have extra power for added headroom. Just be careful to use it for that
purpose.
Also, keep in mind that simply adding amplifier power will not necessarily
increase your volume significantly. The addition of more speakers will
usually have more impact on your overall volume level and improve your
overall presence and tone.
