Next investment after VR: Simshaker or premium throttle?

If I may what was the overall cost?

 

The BST-1 was a bit pricey compared to the TT25's. You could do it with just the TT25's no problem and you could get the amp and TT's for about $80 USD. The bigger transducer, BST-1 looks like it is around $50 USD.  But it seriously kicks. My wife gets frustrated sometimes because the BST-1 shakes the chair pretty hard and is audible across the house.

How are you running three transducers from that, out of curiosity? It's a 2-channel jobby.

 

The amp is a 4 ohm 2 Channel amp. I'm running the two TT25 (8 ohm) in parallel off one channel and the BST-1 (4 ohm) on the other channel.  Together will all three transducers, it will SERIOUSLY shake the heck out of the chair. I usually keep it pretty low volume so as to not annoy anyone in the house. 

 

When I fire up the sim in VR and forget to turn on the amp, the world feels lifeless.

How do you find its power output, enough to crank up the volume? I have two Fosi amps coming, each one supposedly 100W RMS per channel but the word is, unsuprisingly, will be lucky to get 35W out of each channel.
My transducers are 50W each (BST-1), so with four of them I'm expecting something to blow up. Lol.

I can max out the amp with gun fire / heavy shaking if the amp is maxed. I don't know the exact peak power output but obviously I'm not driving the transducers as hard as they can be run. It's a cheap setup and I know a few other guys who used the same Lepy amp as myself for their sim pit shakers. No complaints. 

You'll be able to seriously crank your setup I bet.

I will report back. The Fosis were 'cheap' (£65 each) but if they melt they'll be going back to amazon for a refund, under the heading "false advertizing". If the watts are genuine I'll be amazed. 100W per channel at 4-ohms, in a tiny box? HOW?! Lol.

How high you crank it up depends on what you've mounted them to, what your cohabitation situation is and if you want it to change and where you lie on the informative-vs-spectacular spectrum.

Only one amp was sent (they took money for only one, so no biggie). And one transducer is defo dead, tried on two amps and with two different sets of wires. That's got to go back to France. Puh.
As for the vibes, with the vol up too high the two trans got TOO HOT TO TOUCH. That has to be caused by the poxy little amp being nowhere NEAR 100W (under-powered amp can blow a speaker, who knew) so it's the clipping causing that I guess. But at low volume it's decent. But THE RACKET! Oh...my...god.

[=420=Syphen]

I do not subscribe to your theory that under powered amps will cause damage. If that was the case, I'd have ruined my BST-1 a long time ago by giving it only 10w rms on its channel.  It's rated peak is much higher. 

These are bass shakers, and not dainty tweeters.

If they are constantly rumbling (you got engine vibrations on for example) some heat is to be expected since it's excess energy that isn't all dissipated as kinetic but "too hot to touch" sounds like wiring done in parallel and the impedance halved. Since you say you have 4 of them, are you connecting them in stereo and if so how is the wiring done? Is it per instructions found in Dayton's site (https://www.daytonaudio.com/product/1245/bst-1-high-power-pro-tactile-bass-shaker-50-watts)?

Currently using only two of them. I have them hooked up to the one mini-amp, simple + and - to + and - terminals (the mini-amp is 2-channel).

I did try the pair in serial connection but they lost a lot of oomph.

I see - I run my BST-2's off of a 2x70 car audio amp with it's gain set to the lowest level since that's what I had lying around, bought it 15 years ago but something similar would cost like 50 euros and be sufficient to power the whole deal instead of dishing out for multiple small amps. That way there's a single stereo cable with a jack going to my chair, since I've got them mounted under it, which I can unplug and stow away when not using.
