The large mid range plays smooth enough and quickly drops off past the xover point and shows a little bit of break up after 5khz.
The Tweeter is a touch on the mellow side and it is reasonably flat. It rolls off slightly after 10khz. This is not an in your face speaker, but a smooth and full sounding one that does a lot of things very good. But once again, the design is slightly hampered by the grills forced upon the drivers.
Overlaying the outdoor 1m measurements reveals a quiet reasonably flat output. Not all that different from Andrew Jones' previous Pioneer speakers. A little bit elevated in the midrange with helps with a smooth warm sound.
There is a bit of a wrinkle at 2.5khz to 3.5khz. I would take a guess that it maybe do to some of the cone break up.
Similar to the Pioneer BS22's,overall the treble is a bit down from the midrange. And the grills cause issues lower in the frequency response than I have seen in any other speaker I've measured. All the way down to about 1.8khz, there is at least measurable effect.
The difference between both grills removed, and both grills on remains apparent in the tweeters output. Without the grills on, there is a significant peak at about 14khz, that's pretty high in the range and probably not going to make an audible difference to anyone though. I'm not sure why that peak shows up in 1m measurements, but not close mic measurements, but I suspect it's due to the pretty deep horn loading of the tweeter driver.
Overall these are really nice speakers. They are too large for any serious near field or desktop listening, and you have them that close to the wall the bass can be pretty overwhelming and a bit bloated.
As a non near-field 2.x or surround sound set up I think these B6's would perform great. They do a lot of things right. They are smooth and reach deep for their size, but if you are like me and tend to like something with just a little more sizzle you might have better luck with something like the KEF q100.
Later we will see how well they do off axis. SPOILERS...they they are great at it.
