Thanks Alan .... yes, it can be confusing. Alto of this is confusing
I think I hear much then same way as SKINS does.
Here's what I get from this all is that, if we're doing this audessy, or manually setup. If we are setting our Mains and centres to small and cross overs at 80hz, then most of the 80hz and below is going to the subs. SO, if the VP150 sensitivity is down to 80hz, really what are you guys hearing below 80hz in the centre's ? given, that no sound below 80hz is even going that way. What I get from everyone is that the larger boxes are better for bottom end sound. Does, the size of the cabinet effect much of the sound between 100hz - 2k ?
The vp150 seems pretty well flat, there using the exact same drivers the vp180 is using.
I guess the only difference would be the croosover point at 150hz, in that the vp180 would be using the 6.5" drivers and most likely this is where most of the difference lies
