That's what I said... You can't damage drivers by underpowering. Reread my previous post...
All I am saying is that a 200 watt head is going to sound bad through an 810 because it's not enough power. I stand by that. The head is going to start clipping and it will sound like crap. Especially a budget head like the B200H.
But no damage will occur. We all know this.
I think you guys are getting too caught up on nit-picking this kind of thing. If someone (especially a new bassist) posts a question like this, they are not only asking if it will "work" they are asking if it will work well. So, for the sake of being rational and practical, the answer should reflect such considerations.
It's like asking "Can you swallow a spoonful of broken glass??"
Well sure, you feasibly could. Is it a good idea? Of course not.
But, regardless, this should all be friendly, professional discussion. No need to get upset.
