So from a sound quality first standpoint, the VTF-3 is the best match to my TN1220HO's? Ok. So the inevitable follow-up question becomes, what would be the downside of going with a VTF-15 instead from a sound quality perspective, if any?
The price difference isn't enough to scare me, nor is the size & weight, because I've got 2 subs that a mere mortal can move without getting help. So, for the job at hand, which is flatter in-room response, the size & weight aren't big problems.
I know the VTF-15 will have higher SPL, which is low on my list of priorities, I know it'll play deeper, which is a bonus, but not critical, and I'd assume that when I gain match the subs, it'll play at lower distortion (as will the TNs). So, I'm just wondering if the VTF-15 wouldn't be the better buy unless you think there's a downside to the lower port tune and integrating it with the TNs?
You could make my life easier and re-introduce the TN1220HO mk2, just throw the VTF-2 driver in a 4' chunk of sonotube and you'd sell at least 1 pair today.
