Hardware & Technical Help with bass shakers? I dont know amps or speakers.

Hey guys, im looking at putting two bass shakers on my flight chair but i know very little about amps and tech around them.

The chair in question is the passenger seat from a vw golf 3 on a simple 2x4 stand, my initial idea is to put one shaker in the back and the other in the seat, connected in parallel, would someone with experience in this area do it differently?

These are the shakers im looking at:

The numbers i guess are important are as follows:
30W max
15W rms
8 or 16 ohm versions available at the same price, havnt ordered yet since i dont understand the difference.

I would very much like recommendations and pointers towards getting this right.

How many watts does the amp need to push?
Ohms should make some difference here but what?

Basically what specs do i need?

My idea for how to connect this is mirroring the sound from the vive output, low pass filtering the signal via software, outputting that to one of the 3.5 jacks on the comp and feeding it into an amp to drive the shakers.

Speaker impedance has to be suitable for the amp; I'd assume that most amplifiers will happily drive 8Ω speakers, but find an amp first. 15W should be plenty.

AFAICT any cheap amplifier should do (even something like this (not an endorsement)), the transducer will take care of filtering with its narrow frequency response and you just feed it the full range signal.

Figured id report back with some results.

I got two of the 16 ohm shakers i was looking at in the mail today.

I didnt go get an amp for them but instead opened up the sub of my 2.1 system, snipped the wires to the element and hooked the shakers up to it instead.
(im gonna make an external connector and switch but for now i just have the sub electronics sitting open)

The sound output from the vive headphones was mirrored to the speaker jack after being passed through an eq that sifts out high frequencies.

I jammed the shakers inside my car seat, one centered just below the shoulder blades and the other where the backrest meets the seat itself.

Works great :)

Now i just gotta figure out if taking it further by building a motion rig is a probable idea.
