I see there`s alot of good words about the TecAmp 212 cabs here, well, I played a gig last night with the Puma Combo 212, and IMO it was no good at all. No precense, no volume, nothing. Very scooped tone, reminded me of some of the Ampeg stuff. I was pretty shocked, cause I love my L410 cab, but this sounded nothing like it.
I guess 12" are not for me, and I`m starting to think that the lightweight heads may not be for me too. I don`t like lack of low-end headroom of theese amps.
Careful there. First, the Puma 212 combo is 8ohms, so you are only getting roughly half the power of the Puma500 that drives it. Secondly, the combo cab is a completely different design from the s212 and your L410. The combo has a non-adjustable paper cone mid driver, not the tweeter that your L410 and my s212 have.
There is absolutely no difference in headroom these days between a lightweight amp and an amp with a heavy power supply IF they are roughly the same watts.
You experience with the Puma500 run into a 4ohm s212 would have been much closer, IMO, to your experience and tone that you get from you L410 (although still not the absolute volume of a 410). My 410 cabs bury the little s212 also, but the tone is amazing (I assume very similar to the L410), and the volume is quite amazing for a 40 pound 'micro sized' 212. However, IMO, the Puma500, like most other moderate wattage heads (lightweight or otherwise) really doesn't open up and scream into a single, small 8ohm cab.
IMO!


By either pushing it really hard in a small room or just a little bit of poor EQing, which can go wrong really fast with this powerful little amp. But these instances are beyond what I would describe as 'normal' operating conditions, and I assume the same could be done with the similar 4 ohm 212 cabs etc.
