Advice Requested: Fine Tuning Bass Shakers Using Peak Limiter (or any other DSP)

[Jose Sifontes]

The bass in my home theater setup is supplemented by two bass shakers (Dayton BST-1s) in my HT chair, fed by an iNuke NU3000DSP running mono. The effect is great in general, but exaggerated/unrealistic (the signal source is one of the receiver's two sub outs). It kicks in too frequently. I want it to be barely noticeable and tied to the LFE intent of the movie's director. To this end, I have tried reducing the low pass crossover to 30Hz (with a steep LR slope of 48db) and played with the volume control in the iNuke. This has helped, up to a point. What I would like to do is go further by using the peak limiter. I understand the limiter in the iNuke is "forward-looking", etc. Any experience here using it to control the duration of effects for a bass shaker? Any guidance appreciated, even outside the use of the peak limiter function. I also have a miniDSP 2X4HD that I can use to control the effect, so not limited to the iNuke DSP engine. Thanks in advance!

I am also looking for input on this subject. I just built a riser that I am going to put 9 Dayton (BST -1) in and also stuff it with insulation to create a bass trap at the same time. Specifically time delay is my concern. Eventually I will have 4 subs running off of the mini dsp. If I use a Y splitter off of 1 of the channels will this be sufficient? I currently only have 3 so it isn't a problem yet. I should receive the shakers in about a week.

I was also wanting input from others that have built risers for options they wish they had included. I think that I will do some lighting and was wondering about putting a power outlet (110) in it.

Any input is welcomed.
