Some time back I posted in here regarding lack of a sweet spot when
using a pair of IPL transmission line speakers. I never did resolve the
problem and just lived with it...until now. I've just bought a pair of
Behringer B2301 near field reference monitors and the difference is
astounding. I'm hearing high resolution and detailed images both
spatially and acoustically with these speakers. Which makes me
wonder...IPL speakers are quite high spec and I would not have expected
so much difference, especially with my ancient ears. I haven't done any
proper A/B tests. The speakers are not even in the same room, for
example. But there must surely be a problem with the IPL units.

IPL speakers come in kit form...is it possible that I have gotten
incorrect phasing to one or more drivers? The bass drivers are
correct...is there an easy way to check the others without
disassembling them (a chore)? Any other ideas/suggestions?

Problems with imaging may have nothing to do with the nominal frequency
response of the speakers. May be due to other factors like their radiation
pattern, colouration due to other parts vibrating, how this all interacts
with your room's acoustic, etc, etc.

Slainte,

Jim
