This is by far the best video I have found on setting up base shakers/tactile transducers. No one seems to mention that these things need to be tuned, especially if running from the LFA on your receiver. So, thank you for putting this together! I am hitting the exact problem you are describing. System fully tuned and timed using Audyssey One (A1 EVO) (it's amazing, by the way Google it if you have not heard it ) on my Marantz SR6014 receiver. I currently have two independent subwoofer outputs, each connected to its own subwoofer. I recently purchased four Dayton Audio BST-300EX. One for my chair, and three for the couch, with an individual amplifier for each shaker. So, power is not my problem. When I run the sub output from my headphone amplifier into the shaker’s amplifiers, I get amazing power. Can barely turn it past three. When I run the LFE out from my receiver, using the Audyssey One corrected LFE corrected output, virtually zero sound unless I crank the shaker amplifiers about three quarters of the way up. I do have two miniDSP 2 x 4 HDs. Sounds like what you are saying is I could split the LFE output from the sub 2 output, and run one straight to the subwoofer, and run the other into one of the mini DSPs. Then I can boost the gain and adjust the EQ to add back whatever Audyssey removed from the receiver's LFE’s output? Is that possible? I watched another video where I downloaded an app for my android phone, called Accelerometer. I can place in my actual sitting position and measure the variance in the vibration in 5 Hz increments from 5Hz up to about 60 Hz, where I would cross over. I can do this just using simple test-tone videos on RUclips. So, basically use the accelerometer instead of a microphone to get the measurements to boost or subtract certain frequencies. Would this work? Anyone else have any input? All input appreciated. This has been making my head ache for a month now! Either way, I hope you come out with that new video soon! Sorry to be so verbose. Typed this too fast!
@@hifihometheater Still waiting on that tutorial, brother. :). I have a new Denon 4800 with 3 RSL 12s subs, Dirac Live w Bass Control, and all the equipment to start messing around with this - NX3000 amp, 4 Crowsons, minidsp, etc. This video is a good introduction. In my setup can i have JUST the crowsons attached to the minidsp by itself? FWIW, my crowsons and one of the subs will be connected to the receiver wirelessly using a pair of SVS wireless kits.
I have 4 AURA bass shakers in my sofa , I use 2 external plate subwoofer amp from Dayton Audio SA100 100W Subwoofer Plate Amplifier , with parallel connection and all of then is connected with a Y splitter to my Denon 3800H transducer sub output , i use the plate sub amplifier so I can control the frequency without using a mini dsp
Great video Brian! Thanks for the mention about the Crowson Guide! I love the visual explanation about the linear LFE signal issue using the ARC Genesis app. It really drives the point home.
Nice job on the video. I just purchased the carpet spikes and will try it. Regarding EQ I agree you must consider the already established EQ done to the subwoofers along with the frequency response of the shaker/transducer. In addition the EQ must take into consideration the mounting configuration and resonance of the couch/seat and transducer as a whole unit. I have found success with using REW to check the combined frequency response on the seat and taking that EQ adjustments to the mini dsp output for the shakers. Then I run step frequency checks using the “butt meter” with the subs on for final frequency dsp confirmation/adjustment and output checks. This final check may require some changes to the EQ and shaker volume level.
That depends on your setup; If your AVR/Processor can provide a separate, unEQed LFE signal and you still want to use its room correction on your subs, you would want to use both inputs. If you cannot get a separate clean LFE signal, you would use jut one input since youll need to EQ it with the MiniDSP anyway. You would also only need one input if you are doing all the subwoofer EQ in the MiniDSP and not using room correction and/or minimizing its impact on the LFE channel.
Thanks for the video. Would be great to understand more about how to not feed a corrected signal from AVR to the TR device. I have a Denon 4700H and not sure how it would work and also how best to dial in them with the subs. Thanks
I do not believe the 4700 has this ability. I have a 4500 and it does not. As noted above you can create a transducer specific curve to offset the subwoofer EQ
You have a few options Get a denon 3800h for example that has a transducers option Or do not apply corrections to the LFE and do any EQ with a MiniDSP OR use the MiniDSP to "cancel" any EQ from the avr A MINIDSP is a must have IMO and it also will let you run BEQ to really make that TR come alive!
@@gabrieltechreviews8185 Thanks, I have a minidsp, actually 2 now waiting on my Crowsons to arrive. I should explain my set up. I have 4 SI 24s, dual NSW 21s and dual SI SQL 15s for subs running through two CVR amps and one minidsp 2x4HD and Denon 4700H. I am very well versed with subs but not so much with TR devices. How would you cancel any room correction EQ in the mini? How do you go about doing that? I have been using BEQ for a few years now so hence bought a second mini to daisy chain them. Thanks
If you have the mini DSP and REW just place the microphone on the seat and run a sweep and see what the tactile response is at the seat. Once you see the response you can tune it like any other sub. Your first response graph will include any eq applied by the receiver. In the mini DSP can be used to create an EQ for just the tactile transducers. Hope that helps

Really appreciate this video. Very clear delivery. Would also appreciate a minidsp setup tutorial like you mentioned. Thanks
Thanks. I plan on doing this tutorial in the near future

Great video. Does it matter if use just 1 input on MiniDSP for couple subs and transducers or need to use both?

@@hifihometheater thanks. I have a Denon x6700. Has 2 sub outs. Not 4 with the transducers channel like the new 2023 models.

@@rickcohen4680 must be missing something here. The Crowsons won’t have any SPL so how will a sweep register in REW?
