That's why I've taken a fair amount of time working on my listening room.
I've had it measured twice now and both guys said I have slight
bump at 40hz, (about 1.5 db) that's it. With careful speaker and
subwoofer placement, I've been able to eliminate it.
My living room though is the typical room that most people have to
deal with; windows, hardwood floors and area rug, big coffee table
along with limited speaker placement options. I see this room as more
of a torture test.
Also, that's why we like to try speakers that we have in for review
in at least 2 or 3 different rooms. We also try any given pair of
speakers with at least 6 or 7 different types of amplifiers to see any
incompatibilities. When I worked for Harry Pearson, he used to demand
that you tried a review set of speakers with at least 3 or 4 different
types of amplifiers.
I own (not on long term loan) a CJ Premier 350 that will pretty
much drive anything, a Nagra PSA (100wpc solid state), a McIntosh
MC275, Red Wine Audio 30.2, CJ MV-75a1, a Rega Elicit and a
Luxman L-590aII.
In addition to that, we always have about 5 or 6 amps in for review,
so that makes it pretty easy to spend a few days in the review cycle
just trying different amps and cables.
Of course, we can't try everything, but we do have a pretty reasonable
cross section.
I always ask a mfr if there is a magic combination that they prefer with
their speakers and try to get it and see how it compares to our stuff whenever
we can.
