Are you happy with the trade-off this speaker represents in that regard? I don't know enough about these designs to say confidently, but I feel like cabinet volume, extension, and sensitivity could be manipulated to minimize excursion at reference and maximize HF fidelity. So, I guess the first issue is do you think the HF is refined enough when the bottom end is pushed hard? And related, do you have any concerns about being able to drive them to reference in your space? (would you be willing to give up two or three dB sensitivity?) If that is possible (I think it would need more volume) any ideas what that would dso to the native FR and how that would influence your opinion on the final result? (sorry - too many questions)
Fred, I've been considering your thoughtful post all morning. My thoughts have ranged from "I don't have the ears to discern such differences", to "I don't listen loud enough for that to happen", to "I'm not knowledgeable enough to answer intelligently." Since I've never let my lack of intelligence prevent me from wading in and offering an opinion or an intelligent sounding response, I'll give it a shot:
I am familiar with the discussion you mentioned and it makes a lot of sense to me ( whether I can hear it or not ). That was part of the reason why I went with the V10 over the V8 and also why I went sealed rather than ported. It is also why I am crossing my surrounds over to my sub at 120 Hz. With regards to trade offs, my selection was primarily driven by price sensitivity.
Noah has already addressed the factors impacting woofer excursion, and I have not pushed these speakers hard enough yet to determine what if any bad habits they may exhibit when pushed. They sounded a little nasal in my test enclosures which were smaller and unstuffed, but the finished speakers sound similar to my Cheap Thrills, but not quite as open and precise.
I run out of amplifier before the V10s run out of response, so I can't answer how they perform at their limits.
I'm not sure I understand the last part of your question. I don't have a calibrated mic or SPL meter, so I'm not sure if they play at reference levels or not.
