Hi Fred
I dunno if it answers the question or not, but it's an interesting comparison. The BLH is very rough and peaky above 200 Hz, but most of this would be rolled off by the muffler effect of the labarynth in most typical designs. While the FLH goes lower, the BLH has a nice flat plateau from just over 50 Hz to over 80 Hz, which gives some justification to using this design over a FLH where use of a reactance anulling box is possible. Contra to this is the predicted 140 Ohm peak for the BLH at just under 20 Hz (yikes!) where the FLH is nice and flat. So it looks like there's both some good news and some bad news for BLH's and us double loaders too.
Thanks Freddyi Labs!
Paul
