Settings for bass shaker

[Audioholick]

I’m trying to configure my system for LCR two way active mains, 2x rear/side “small” speakers, one sub, one bass shaker. How would I go about setting up a lfe/bass output to the shaker that doesn’t require a measurement to be taken or any correction filters applied bar a crossover?

The best solution is probably to create a target that follows the measured response of the shaker.

If you have a subwoofer output that isn't getting correction filters from a room eq, then all your really need is timing correction and a crossover. I use a mini dsp 2x4hd or a flex balanced to do this. Timing is critical, or it will seem fake. No special tools needed. Just a song with a known repetitive kick drum. Match the timing of what your ears hear to what your butt feels. Mine ended up at 12 milliseconds. If you can't get a non-corrected signal, I would suggest trying anyway. It may not matter. There are ways to remove the correction filters but it is not fun. I've not had to do it so I'm really not qualified to tell you how to do it. Basically from what I understand you will need to make filters in the opposite direction of what room correction did to the signal. I hope this helps.

Thank you for the reply, I have a mini dsp 10x10hd that I am taking out of the chain and using audiolense to do a 3way active setup I maybe didn’t explain very well but I’m wanting another sub Chanel in audiolense that doesn’t receive correction as there isn’t anything audiable to measure from the shaker an I want it to receive a unfiltered signal (bar the x over) and still have the real subwoofers to have proper correction

I have been using it for years with the same filters applied to the sub but I think it would be way better without, my room has a 15db 40odd hz room mode that is being cut that th shaker doesn’t really need taking out

Can you apply an independent curve to single channels?

No, but to single speakers.

After giving this a bit more thought. It may be a better alternativ to apply partial correction for the shaker, with no correctio above 1 Hz. This setting will take care of the timing (I just hope the output is such that the timing can be captured properly through a measurement).

It should be if I set the mic stand on the sofa
