I use Dayton Puck, bought from California, USA.
When the first one arrived early last year I was sceptical about it? WOW it really does vibrate for such a dinky small size.
I experimented with various placements to find which location on the seating can provide the most vibration with less power or gain input from the mixer that I use the fader/sliders and master fader to set level for each film.
They are fitted into the seat buckets of the Irwin cinema rocker seats.
I have so far settled on some MDF off-cuts with drill saw cut into the MDF and fitted the PUCK.
Replace the seat cushions back to the seat buckets.
The audio mixer that has the line outputs from LF LCR and SW from THX sound system feed to the line inputs on mixer.
I use sine wave spot frequency tones to test and not a whole lot I can do when the seat rattles expect turn the gain level down so its not distracting.
Too many films that feel exciting.
"APOLLO 13" dts THX Laserdisc, when the astronauts are getting strapped in the command module, from a foot pressing into the shoulder and strap harnesses pulled damn tight!
Feeling the hand grip at 34m 58s as (Tom Hanks) "Lovell" prepares launch.
Fuel pumps rumble the seats.
"Fuel pumps. This is it. Fuel pumps and we're hulling the mail."
Powerful rumble track!
I can feel it in seat bucket the seat back the armrests and partly in the seat flooring and some bass mid to the chest at times.
:banana:
I did some calculations a few weeks ago that it would be possible to fit x6 maybe x8 into each seat bucket but that would be pushing it. Not for silly seat rattle to the point where it breaks apart. :yikes
What I'm after is separate LCRS and LFE.1 in the seat as I get worried about blending all channels onto a single PUCK. So far no problems and that is how I like to be.
I'd have to use thicker MDF not too thick otherwise the seat cushion might have problem latching back into place?
