Infinity Modulus loudspeaker & Modulus subwoofer Page 2
Both satellites and subwoofer come with comprehensive Owner's Manuals covering all aspects of setup and use and offering good advice on where to site the units within the room to get the optimum sound. Would that all loudspeakers were as well served in this respect. The sound

Oh cool. I would connect it to the sub and connect a speaker amplifier from the high pass output. Then tune the sound by ear. If you want to get technical use REW with a microphone to determine the frequency of the high pass output and also too match the crossover frequency to the speakers.
If you can tell me the amplifier make and model that you use for the speakers I can help you with the switches settings.
Thanks
) that's how I've done it.I've matched the input impedance of 45 kohm with my luxman m03 (swiycged 1 down all the other up)
Very nice. I am familiar with the M03. You have the switches in the correct configuration. How does it sound?Thanks

Thanks!! My previous attempts were not successful...who knows why??
Now sounds Somewhat more homogeneous...I'm setting the crossover at 60hz, phase slight above 90 deg, level mid high.
Cutoff frequency 22hz although with 35 hz makes no difference to my ear so far
I'm listening to the hubiquitous you want it darker from Mr Cohen...those bass lines choir in the back
Always challenging for every system.

Reading again the review from Mr Atkinson it appears that you can extend the bass by a handful of of decibels ....what that actually does? Is there a mini op amp to bood the octaves? Or it's all passive?
The sub frequency response should be as as low as 22hz...
Infinity Modulus Subwoofer: sealed-box, servo-controlled subwoofer with integral 250W amplifier and separate control unit. Drive-units: 12" IMG (Injection-Molded Graphite) cone woofer. Crossover frequency: 140Hz, high-pass; adjustable from 40Hz to 210Hz, low-pass. Crossover slopes: 1st-order, high-pass, 6dB/octave; second-order, low-pass, 12dB/octave. Bass extension (–3dB): selectable, 22Hz or 35Hz
Maybe you just need music or movies with that low of frequency output.
To boost...sorry:)
It's OP amp crossover circuitry. A passive crossover would be larger I think. Agreed

Exciting! Full-range speakers plus sub together. LP + HP filter. Test corssover point 80 Hz. You do not want to be able to locate with your ears where the subwoofer is, where the sound comes from the subwoofer so around 80 Hz you cut off steeply, LP filters for example 24 dB steep. You do not want a subwoofer without steep filter that let through higher frequencies.
In order not to mix frequencies /sound from top / full-range speakers with the sub so on them an HP filter.

Then you get to try out the placement of the subwoofer and full range. EQ for sub can make a big positive difference,. You may want to test EQ at a later stage.
What I am saying now has probably already been mentioned in the thread, but okay then it will probably be a repetition then.
Always take rules of thumb with a pinch of salt.

All seems well...positioning might require further try outs
....therefore....
