Post Subject: Sealed Vs...Posted by Paul S on: 12/15/2016
Yes, for practical reasons, one side of an IB driver is usually "wrapped and sealed" to deliver lower frequencies from the other side, since it is generally impractical to actually make a baffle large enough to prevent sonic shorts.  However, at higher frequencies, both sides might be open, depending on the driver, the size of the baffle, and what one desires to get from it.  Whether or not this is actually, technically IB is moot, as far as I'm concerned.  I don't know much about the drivers you cite, but most LF drivers feature a response that tails off as the frequency drops, and - of course - this is where multiple drivers come in, to augment flagging response, using a network and appropriate power to yield the desired plot, especially vs. horns.  Like you (I suppose), I prefer the sound of LF from larger diaphragms and shorter throws vs. the opposite.  Again, I still think of hi-fi ULF as a mysterious thing, build and try, see/hear if it works. At this time I have no practical reference, apart from live music. Since I won't be getting that at home, it comes down to what I can actually do in my house. I don't know your musical tastes or playback expectations, but it looks like you have a nice solution.

Best regards,
