Here the email I received today,
Hi Charles,

We are working on refreshing the BKA1000 amplifier and working towards having it available later on in the spring. You can signup for our mailing list at TheButtKicker.com.

So I just purchased a used bka1000r at a good price to use with the earthquakes. Should install them early next week. I will report back.
Owning a BKA1000-N I was curious what a 1000-R was but I could not find it at all. Are you sure it is not a 1000-4 you have bought.

If you are interested here is a review of the 1000-4

The only obvious difference I can see is that the 4 has selectable voltage switch on the rear panel while the N does not.

Oops, sorry you are correct. It’s the 1000-4. I purchased this for well below $200 shipped. Didn’t want to spend a lot on an amp for shakers since this amp is rated so highly. Will check out the new Buttkicker amp this summer.

So I just wanted to give a quick update. I’ve been working on my first chair using one earthquake MQB1. Unfortunately I don’t really have any great spots on these theater chairs to mount transducers. So I attached a piece of oak board to the metal bottom frame. Off center because the recliner mechanism is right down the middle. My bka-1000 hasn’t come in yet so I’m using an old Sony 100 watt receiver. First impressions are very good. I use a v1801 sub right behind my middle recliner and these earthquakes give a similair effect. It’s like @markmon1 said “ it’s like having a giant sub firing into the back of the chairs”. My only issue is that because I had to mount off center I get more vibration off one side of the chair. I might install two per chair and wire them in parallel 4 which I believe will be 2 ohms which the buttkicker can handle no problem. These things don’t need a lot of power for a great effect.

As soon as the BKA1000 is in, you have more tuning possibileties.
Do you have Pacific Rim?
It seems that with the heartbeat scene, you can tune the delay really good.

My delay will be fine hopefully as I have a nearfield sub that I will be splicing into. The biggest thing with these transducers are having a good place to mount. 1 is pretty potent but in my situation I just have limited places to mount. 1 shakes the chair really well with a low power amp. These earthquakes are no joke. They are tiny but do the job.

If you connect it parallel on you sub, it will probably be in sync.

I was thinking about only using 1 Earthquake MQB1 for each sofa, placing it in the middle of a two seater, but that is a no go?

You might have more tactile toward the middle and little on the ends. It’s all about experimenting. My issues is not having a good spot to mount. Of course it will depend on how much shake you want. If I could attach to wood base 1 would be enough per chair.

Well one chair done for now. Took me many hours lol. On my cHairs there are not many good places to mount transducers. No wood on base just steel. I looked over the Crowsons thread with some guys that own the same chair as me. They found that attaching to the steel frame gave best results, so that it what I did. I first tried one earthquake and that shook the seats very well but most of the shaking was done on one side of the chair. Today I added a second and that made all the difference. My Buttkicker 1000 came in today so things are great. I’m tweaking the level as I find lower is better, especially with two transducers. My plan is to purchase two more and add to my other seat. As I understand it the amp can handle close to 2000 watts on a 2 ohm load. Combining 4 8ohm transducers in parallel would make a 2ohm load I believe? I’m new to transducers and more complex wiring but I think I have everything set up correctly. Thanks to those that recommended the earthquakes. They are pretty awesome. I was lucky to buy both the earthquakes and buttkicker used so I don’t have a ton of money into this.

It's nice to see the Earthquake TTs getting some love. IME their build quality is far superior to Buttkicker's. Their torque multiplying brackets also make a big difference. I'm guessing Earthuake has a patent which is why we don't see other similar brackets. If I had access to my subfloor I would install a Q10-B. 1 MQB-1 per chair works wonderfully (directly to chair or to platform).

You have the Earthquakes on top of their plate. Do they work the same underneath the plate, pointed downwords?

Hi Marc
Did you make that up? I was intrigued and Googled "Earthquake transducer torque multiplying bracket" but no hits. I visited the Earthquake site and not a mention. It must be a closely guarded secret and you have just given it away. :smile:

The brackets they come with increase the effectiveness vs mounting directly without the bracket.

Here is the platform bracket for the Q10-B, https://www.amazon.com/Earthquake-Shaped-Platform-Bracket-Transducer/dp/B00EEDAVZI

I just wanted to report that I had to modify my existing placement somewhat due to contact with the mechanisms underneath. I moved each transducer forward about 4 inches and have no issues. This resulted in even better tactile. I can’t say enough how much I am impressed with these little transducers. They blend right in with my subs and give the perception of many more subs in the room. I use a very nearfield v1801 right behind my chair and I’d say with it turned off it still seems like it is on with the use of these transducers. Now my chairs are on cork flooring. How much benefit does adding those absorbers give you? I was looking at the small little pads you place under each end.

Thanks for that Marc.

Now you pointed me in the right direction it is easy to find. :smile:
