Hi guys! I own the Hartke LH500 amp head and an Avatar 212 bottom, both brand new in the last week. I am planning to purchase a second Avatar 212 bottom and am concerned about the sound quality when connecting both cabs. Both cabs will be 8 ohms. I spoke with Ampeg tech support as I was also considering an Ampeg SVT 3 Pro (which is a 450 watt RMS amp) and they informed me that with my speaker selection, I would be way under powering the 2 cabs and really should consider a head with more wattage, such as the SVT 6 Pro. But the weight on that head is 41 pounds and said no way! So I want to know from some experienced players if I use 2 - 212 Avatar Neo cabs and my Hartke LH500 (500 watt) head, will I be ok and get good sound and not ruin my speakers or should I get a more powerful bass head? Any help will be much appreciated!
