Advice regarding some transducers for shaking

[markturner1960]

I am having some hardware issues with my jet seat and thinking of supplementing the vibes with some additional transducers. Last year I added a single sub woofer to my main sim pit and it works well. This time I am thinking of adding multiple smaller ones to my Helo pit, using the same amp. 

The componenets I am thinking of using are as follows:

This amp: https://www.amazon.co.uk/dp/B0725PJQQV?psc=1&ref=ppx_pop_dt_b_product_details

This for the largets woofer, under the seat: https://www.amazon.co.uk/Dayton-Audio-BST-2-Tactile-Shaker/dp/B08NN5V62G/ref=s_d_sccl_1_4/259-7660510-0402368?pd_rd_w=KXzpg&content-id=amzn1.sym.a5abc27b-3361-46a8-8070-e72e5f18953c&pf_rd_p=a5abc27b-3361-46a8-8070-e72e5f18953c&pf_rd_r=05MVGXZPE6EMEY0YCRZT&pd_rd_wg=z5Zvt&pd_rd_r=c9a9b849-2e03-4f7f-906a-462d3ef873c6&pd_rd_i=B08NN5V62G&psc=1

And two of these for the seat back / sides: https://www.amazon.co.uk/Dayton-TT25-8-Tactile-Transducer-Shaker/dp/B009RGJ47S/ref=s_d_sccl_1_2/259-7660510-0402368?pd_rd_w=KXzpg&content-id=amzn1.sym.a5abc27b-3361-46a8-8070-e72e5f18953c&pf_rd_p=a5abc27b-3361-46a8-8070-e72e5f18953c&pf_rd_r=05MVGXZPE6EMEY0YCRZT&pd_rd_wg=z5Zvt&pd_rd_r=c9a9b849-2e03-4f7f-906a-462d3ef873c6&pd_rd_i=B009RGJ47S&th=1

Is this a good choice and will the amp be able to connect all  of these and operate them well? 

Thanks for any advice

I run the Nobsound amp and a single BST-2.  If you can buy the amp without the power supply and use your own power supply I would highly recommend it.  I'm using an old 19v laptop supply now, it's around 4 amps.  The standard power supply felt like the setup wasn't working at all.  It's the make-or-break element in my experience so far.

You can have the BST-2 on one channel and the pair of TT25s on the other channel and they'll work, but I don't think you'll get any directionality out of them.  I'd be tempted to skip the TT25s and do whatever it takes to add a second BST-2 and set one up on either side of my seat, but that's just me.

Interesting , thanks, can you link the supply you are using for me?

I can't, I'm sorry.  It's just an old laptop PSU from a decade ago, 19v and 4a.  That's 76w being supplied to a 100w amp, so I'm still underpowering it.  But that's only powering a single 35w speaker, so it isn't too far off being enough for my setup.

If I didn't happen to have that old laptop power supply, I'd have been looking at something like a Meanwell 24v power supply from a 3d printer.  The thing to keep in mind is that you're powering something that needs to power two 50w channels, so the closer to 100w on your power supply, the better.  The original power supply that I tried was a 12v 2a wall wart, so it could only manage 24w.  Spent hours trying to work out why the bloody thing didn't work.  Turned out it was working, it just wasn't getting enough power to translate into any meaningful vibration.

Hope that helps a bit.

It does, thanks
