engineering and sales have completely different goals. if they make you want to buy a 115 along with your 410 when your 410 is probably fine, they really don't care if they work as well as they could together. they just care that you buy.
Not to bash other brands, but it's GK and Hartke, not Ampeg. There's a bit more integrity associated with these brands, especially when the founder/owner/engineer run each company and not a board of shareholders.
I'm not calling you out specifically Jimmy, you seem to be one of the go-to guys as far as amp knowledge on this site and I really do value your opinion. I just think its a case of caring a bit too much on behalf of the guys scaring people away from this combination. Is a 410 x 115 combo the most optimal combination? Probably not. But as long as it won't set my practice space on fire or fry my amp, I'm willing to play what sounds good to my ears over what is "the best" combination. I've tried using two 410s and I've tried 410s with 210s and I've tried 810s, and there's just something about a 15 inch speaker that I prefer over all of these combinations, but there's something magical about a 410 and a 115 combo with my fingers. The only combo of 10s that sound right to me (in my limited playing experience) are the Ampeg "fridge" 810s coupled with an all-tube SVT. Everything else is lacking something, IMO.
