I an just looking for some discussion on using 6.5" for midbass vs 8" for midbass. I have heard the output and impact of the 8" is better, plus it can go lower and bring the sub way forward, but is it too slow for the most dynamic midbass passages? Is a 6.5" better for speed? I am talking same manufactures (HAT, Dynaudio, Morel, Scanspeak....etc.) for both, only the size being different.
