RDB-120? Very expensive! http://www.shakercentre.com/aspbite/products/products.asp?intProductsID=13

or? http://www.shakercentre.com/aspbite/products/products.asp?intProductsID=12





I am using the RI-K28 rubber feet as per your link. These are quite soft but work well and on my 3 seat sofa have squashed to about 1cm (less than half an inch) so the sofa isn't obviously sitting on top off some add on feet. They seem to allow for plenty of movement which can also be a tad annoying if your partner is a fidget like mine. :)

I think the feet in the other link are firmer and larger.

The RI-K28 are BK feet, as are the RDB feet and both are listed on their website RI-K28 here (http://www.thebuttkicker.com/home_theater/accessories/RI-K28.htm)

The RDB feet come in a range of weight ratings from 120 to 330 lbs.

Just a quick update to keep anyone informed who may be researching the Buttkicker LFE kit....

I've had it hooked up for about a week now, and find that when I don't turn it on, it feels like something is missing. One BK shaker powered by the 1000 watt amp is plenty to shake my sofa. I can localize where the shaking is coming from, but then again, I'm the one who installed it. I have mine mounted to the underside wooden frame of my sofa. I tried the isolator feet, but since my sofa is on carpet, I didn't feel any difference. All in all I'm very happy, and will probably grab another shaker module for the love seat.

I really dont know where i can buy BK LFE KIT and shipped to finland... its really hard to find with "ok" price...
Any idea? Auras are maybe too "soft"shaking:(

I'd go with the BK or Earthquake if you want a proper job if it and especially so if you already have a infrasonic capable sub.

there is no bk lfe kit, i found that wireless kits only.

how powerful this is? http://www.shakercentre.co.uk/aspbite/products/products.asp?intProductsID=91

can i add more shakers later to amp?

Did you look into using the CMAK with your BK? - http://www.thebuttkicker.com/home_theater/accessories/cmak.htm - Combined with the isolations and located correctly I think it will help your isolation issue. You might have to turn up the amp a bit more but you'll have plenty of gas with 1 or 2 BK's and the BKA. In my emails with BK they recommended this versus mounting to the frame because of the localization issue. They suggested placing the CMAK under the back middle touch points of the frame and using isolators everywhere else. It might be worthy trying this before you invest in another BKLFE. Just a thought

Did you try this location in the UK. http://www.networkmusic.biz/?gclid=COOWh8jSvJ0CFRwhnAodHn3Cjw their add sad they are exclusive supplier in UK. Shipping from them might be better.

I did find some on Ebay UK but again, they would ship from USA. Shipping will cost a bit if based on price because they things are very heavy but that's what you need to create a good effect

I have a question if someone can help. I currently have bass shakers setup on a separate receiver (Thanks to this site). What I want to do is introduce to this setup is Turtle Beach Earforce X31 headsets for late night gaming which when is use, the only this I want in use is the bass shakers and the headphones. The headphones will plug directly into the xbox. I basically want the option to use the normal speakers with the bass shakers or use headphones with the bass shakers.

Sorry for the long post. We will be having a new baby in the house and I need to figure this out.

Thanks

I just got in 2 of the Aura bass shakers and im going to hook them up to a subwoofer plate amp.

My question is how do you know when they are reacing an over load point?

With a traditional speaker you can see the cone movement and you can kinda tell when its reaching its max movement when to back off on the levels.

How do you tell with these things? i dont want to over load it and blow it on accedent but i want to run it about as hard as it can handle.

Three methods:

1. use math. They are 4 ohms and "rated" for X amount of power. Exceed that amount of power for any amount of time and odds of damage is good. The "pro" shakes and the older non-pro are identical internally. Externally the "pro" model has "fins" to aid in their ability to dissipate heat. (I'm not sure I would believe this helps that much, but who knows, you may have better air circulation under your seat than mine.) Fed with the same power, they will shake equally. If you have two shakers in series they will be ab 8 ohm load. If "rated" at 50 watts each you can use a 100 watt plate amplifier. In reality, they will reach their excursion limits at far less power than this.

2. listen to them. They will make really disturbing sounds if near their excursion limits.
Since they will reach their excursion limit at their internal resonant frequency (near 40 Hz) with FAR less power, you might be able to only feed 15-20 watts to each shaker before they show audible signs of distress at some frequencies.

3. feel/smell them. If they are really hot to touch, or smell like they are burning up internally, back off the power.

These things are cool, i didnt think they were going to work to good when i first got them i tried them on a stereo i was using when i was playing with the NXT type transducers and they didnt seem to have much shake.

I took them downstairs tonight while i was watching the football game and hooked them to a 4ohm kenwood powered sub. The one i tried didnt seem to have much shake.

My final setup was to mount them both and run them in series hooked to a 100 watt kenwood power amp. NOW its doing somthing! Not sure if i got lucky and mounted it in the right place or what but wow it shakes good now. WAY better then i thought.

I ran mine in series to give 8ohms and im not sure if that makes them a little more sensative or what but wow what an improvement. I had the amp about 3/4 the way up and it was rockin now its good and its less then halfway up.

I think im going to buy 2 more.

Man these things are costing me more money now.

Now that i hooked em up, i want better seating now to mount them into.

It turned my crappy old chair into a cool rumble seat now i want to find some cool leather theater seats to mount them into

ugggg:confused:

They should add a dedicated channel for these, these are the best thing since 5.1!

Especially when they're $29 a piece. :)

If they were that price two weeks ago, I may have gotten a pair or three of them instead of my Clark TST209. But I'll live with my Clark. :)

Yeah really! figures after i buy a set they drop in price $15.

My sister complained that she dont like them, she said its vibrates her tail bone and makes her butt numb.

Im planning to get some new chairs so ill relocate the shakers then.

+1

hardly know they are there until the explosions start. Then its more shock and awe than sore and annoying.

ok, the problem is im in a wheelchair. I cant really test them myself so i just have to feel the arm rest to make sure they are working. Its kinda hard to judge when you cant feel your legs.

Ill have to turn the chair over and test it with my hand on the shaker till i get it dialed in.

Thanks for the info.
