Now, unless I'm missing summat, I can't see how the (In)Fidelios are
benefitting from the sub - the omnipresent 'traffic noise' (with the sub
up loud enough to 'count' - which it is) and the 'wha wha wha' tail-off
(way behind the speakers) is far more of a PITA than any extra whoomph on
the deep stuff....??

The problem is the sub's gotta go back tomorrow and I've got only a small
'WOO' to experiment with it!



I haven't listened to your samples as I'm currently using the internal
'speakers on my laptop, and they're not the best thing to use for
evaluating subwoofers.


The trick is to drop 'em to a CDRW and bang 'em through your main system,
but no worries...



In my view, the best way to set up a sub is to set the crossover frequency
at whatever you reckon is the -3dB point of your existing 'speakers, in
your case, I'd start with 50Hz.

Start with the level control turned right down, and listening to normal
music (say an orchestra) turn the sub level up until you can hear it
filling in the bottom. Then try some bass heavy music and make up/down
adjustments until it sounds right. If you can't get it sounding right,
then try changing the crossover frequency, say 40Hz.



Thank you for that Serge, but it has all been done - I'm fairly Oh Fay with
the methodology and the 40 Hz setting is the best. (You have not heard these
InFidelios Serge - they are a whole new ballgame, especially as the drivers
are starting to come on song, the Jerichos that you have heard now reside in
the garage...!! ;-)



When I first set mine up, the biggest surprise was on some chamber music
which didn't have any deep bass *in the music*, but there was plenty in
the recorded ambiance, and it went from sounding like a studio recording
to sounding live. It was, by the way, recorded in a hall rather than a
studio, but with the subs, you could hear distant traffic noise.


Well....

One should take a length of Universal Beam about 1200mm long (not too big -
the 178 x 102mm section will do), drill a hole in the neutral zone (halfway
up the web, where compression and tension neutralise each other) about 2/3
of the way along (at the 800/400mm mark) and suspend it from one's scrotum
by means of a noose at the end of a suitable length of prickly sisal garden
twine so that the 'short end' is about 200mm from the ground, with the other
end remaining in continuous contact with the ground. This done, one should
then attempt to engage fully and enthusiastically in a game of 'five a side
football'...

Is how much I need this sub for music...

But never mind me, after all WTF do I know? I made Swim sit through the
first couple of minutes of no less than 7 or 8 tracks of *unbridled techno
bass* (Yello 'The Eye') with and without the sub just now and she picked the
'no sub version' *unfailingly* 'til the very last one and, having lost it by
then, said she wasn't sure!

(I have the opportunity to hook it up for a movie now and asked if she
wanted to try it on summat 'explosive' - *Nope* was the reply, once
again....!!)

Tbh, it puts me in mind of an E-Type towing a caravan which desperately
needs its tyres pumping up!! (And this sub is the best I've had here so far,
sans doute...!! ;-)

There ya go....
