Tactile Transducers
« on: March 21, 2017, 19:47 »
Has anyone compared various tactile transducers available in the market?

What sort of TTs are you using, considering using; and is it worth the effort to implement them?

ATMOS Audio : Martin Logan Ethos (L&R), ML Motif X(C), ML Motion 4 (14pcs surround spkrs)
LFE : Dual Rythmik FV25HP & Crowson Motion Actuator

I own the Crowson ones with the matching amp/filter.

To be honest, I didn't use it after I got the JL f113 and stuck that behind my sofa :D

When I experienced the TT in Desray's setup, it was very natural and complimentary to the LFE content. Very nice, powerful feeling rumbles and shakes. Apparently you need to run a low pass to the TT below 50hz, otherwise it becomes too distracting with the higher frequency content.

That's what I'm finding with a near field MBM behind the couch, since the MBM is run up to 100hz, it becomes quite distracting in vibrating the couch, especially with music.

Should we mount the TT behind or below the sofa?
I think ladies will find it more distracting than guys.

I got the Crowson when I was visiting US and got them to ship me a 240V version of the amp.

The best experience I had was with a scene where a train moved from the right to the left - and the sofa literally shook in the same direction. The Crowson had inputs from 3 line level signals - left, right and sub and with the right filter in place, it worked a real treat.

Sounds awesome =)

U mentioned after u placed the f113 near field,  u did away with the TT. Was it because a powerful near field sub could produce the majority of the effect that the TT does?

Considering to buy one too. But only if the TT can produce much more than a 15 inch sub placed near field.

My near field 15" is giving me quite good rumble tactile

Sounds Awesome!! Thats very interesting, moving right to left. Ive just got in the Motion 8 Crowson Actuators, will be setting this up soon this weekend.

How did you mount them ? At the back of the seat? Did you use any plywood below your MLP? Did you run them from the AVRs preout or?

Yeah it was a really neat effect but I only noticed it once :)

I got the kit with 2 rubber feet for the front 2 feet and 2 Crowson transducers in the back

The JL does a pretty good job of tactile effect behind my sofa so I didn't feel the need to hook it up in the new place.

I kept the Crowson mainly cos I was planning to use it with the Smyth Realiser at some point. Didn't happen then though.

Any other folks compared the Crowson vs other TTs? I hear a lot positive feedback on the crowson...... is it really good?

All excited with the Crowsons in. Just did some minor DIY stuff on the recliner.

Hook up as follows:

2 Shadow 8 Actuators on back of recliner
The D-501 Tactile Motion Amplifier 500w RMS
Speaker cables 14AWG from monoprice 9m x 2
Mogami 2497 with Canare RCAP RCA preout from Oppo 203 Subwoofer analog out to D501
Audiophile Power cable from Shenzhen

Here is the original pic of the recliner before any DIY


Actuator (has got magnet, so it attaches to the metal at the bottom of the recliner) with 2 motion isolator made of rubber


D501 Amp with Low Pass Filter 24db oct, intensity adj, Phase adj, Music/Movie mode


Here is how i mount them, since the recliner is like 4 square rods, I believe it will not benefit from placing the crowsons directly under. So i had a plywood 60mm thick, cut exactly to fit under the recliner. Bought some screws from hardware shop, mounted the motion isolators and made sure the plywood is firm. (since im expecting some vibration). This now allows the crowsons to transfer tactile energy to the recliner and at the same time, since my flooring is laminated timber, it will also give me that tactile sensation at the feet area. speaker cables are tucked underneath the carpet in front. Jag, do you reckon this will impact my neighbour below? The crowsons have some sort of rubber feet isolation thingy.





Getting late, cant do any testing today. Will test out tomorrow after i dial in the crowsons. 50hz low pass and using Gravity & Man of Steel Atmos tracks.
Nothing to EQ since oppo 203 will be sending a clean LFE signal unaltered to the D501. No house curve applied.

This is my first experience with crowsons. So i really have no idea how it should feel and what to expect. May need sifu Jag's help!!
