My two guitarists are gear-whores. One owns a Marshall JVM and the other has a Mesa Boogie Tripple Rectifier. This is extremely annoying. The Marshall is a 100 watt head. The Mesa is running at 150 watts. They are both played through 4 x 12", 300 watt cabs. They crank them up way too loud and drown out the vocals and bass. But I intend to fight fire with fire... I have recently upgraded from a Hartke 100 watt combo (A100), which just wasn't cutting it in practice, to an Ampeg Portaflex (PF-500) head. As a high school student, I'm on a tight budget and was stoked I could even afford an Ampeg. I now need a cab to utilise the amp's full potential. The logical thing to do would be to purchase the matching Portaflex cab (PF-210HE). I could even utilise the fliptop function. But a reliable source suggested that the matching cab wouldn't cut it, as the 2 x 10" speakers wouldn't give me all that much volume. And at $720 here in Australia, the price is a little steep. I'd be willing to pay that much but I need to know if I'm getting my money's worth (they retail at $400 in the US, but shipping costs are insane - more than the cab itself!) The reason I was drawn to the Portaflex series in the first place was for their affordability and portability, the latter also being important as I am carting gear around in the boot of the car every weekend. What should I do? The Ampeg's RMS output is 500 watts at 4 ohms. It need a compatible cab that will cater to my needs, i.e. lots of volume. Should I stick with getting the matching Portaflex cab? Or should I search for something else? Any advice on this matter would be much appreciated.
