Problem: My old Rel Stadium doesn't have a high pass filter, in fact it
has no outputs at all only one XLR input.

Anthony Gallo nucleus micro manual says "If you use a non-Anthony Gallo
sub-woofer that does not have a high pass crossover, then you will need
to use a passive high pass filter."

What sort of filter should I look for or are there other solutions to the
problem?

thanks

Shouldn't be a problem if you use a AV amp- set the Gallo's to small
120hz, subwoofer to 120hz. Connect Micro's to AV amp, subwoofer to AV
amp.

If you have a stereo system a bit more trickier...perhaps line level
crossover between the pre and power sections?

The amp's an Arcam 10 but only in two channel mode - I haven't got the
DAVE module


You could always get rid of the Micros, and get "real" speakers with better
bass frequency response and their own crossovers, removing the need to go
through a subwoofer crossover filter. Just go direct, and dial in the
subwoofer to slightly above/same/below speaker specifications, and adjust
gain as desired. For music sending full-range to standmounts is no problem.

The Rel Stadium is a great subwoofer, so you don't want to get rid of that.
How do you find the filter on it though? I have a Rel Storm and it lets
through much much higher frequency than it should do (ie setting to 40hz and
you can hear upper midrange/low treble from the cone) You could always
remove the amp panel, remove the speaker cable from the amp panel. Build a
new faceplate with just speaker terminals to fit over the hole. Buy a new
high quality amp panel with in/out crossover filter that's does filtering
properly. Put the amp panel someone on your racking, affix the speaker
outputs from the amp panel to your DIY sub panel.



The 'whole story':- The room in question is a 50 sq m
kitchen/conservatory and SWMBO is very keen to have invisible hi-fi. I
started off with two ceiling mounter Sonance Speakers which are fine but
lacked bass. Then I bought an early Stadium off ebay which really does
the job. The problem is that the conservatory end of the room is too
far away from the Sonances and so I was thinking of supplimenting them
with two "Small as Possible" speakers. The don't need any bass response
as the REL has plenty to go round.

SWMBO has approved the Gallos - hence my original question.

I agree with you about the REL - I can hear frequencies that are way
above what I expected but find the integration more gemtle if I keep the
cutoff frequency fairly high and the gain lower.

Where would I buy a "high quality amp panel with in/out crossover filter
that's does filtering properly"?

The hardware is all in a cupboard with Xantech remote repeaters so
appearance isn't too important.
