: Some manufacturers offer the same wattage amp with either 1 15" speaker or 2 10" speakers. What is the advantage to both situations? Also, what does 240watts (150w to internal speaker) mean?


Hey there,
1) In those cases, the difference is in the speaker response. Typically, a 15 will sound fuller and fatter than a 2x10. 10" speakers move faster, and have better articulation on the midrange and the highs (even more if a tweeter is added), while 15" speakers tend to "fill the room" a little more. I used to own a head+2x10 combo which sounded pretty darn good alone, but when I combined that with a single 1x15 cabinet, it exploded!
2) Probably, it means your combo amp sends a 150 watt signal to its internal speaker, but when you add an extension cabinet (as I was saying above), the actual ouptut of the power amp is rated at 240 watts. This is very common in combos that accept extension cabinets. But if you do add another cabinet, remember to match impedances properly. Most likely, your amp literature states the accepted load (it should read something like "150 watts @ 8 Ohms / 240 watts @ 4 Ohms"), so check it out and make your connections carefully.
Hope this helped. Buena suerte and keep your bass up front in the mix,
