I think I am going to go with Clark silver transducers, mainly based on value. They go lower than the Auras. I will be able to get by with my existing amplifiers and I just have to make a reclining loveseat shake.

My main goal is to get more realism and be able to turn the spl down a little. (This will make my wife happy)

My existing sub, a NHT 1259 in a DIY box goes down to about 25 hz.

The Clark transducer says that the tactile frequency range is 15-800 hz and the audible response does not start until 35 hz.

My best guess would be that low passing the signal to the clarks at 30 hz would work well. I would get the most out of them without worrying about them interfering with the sound from my subwoofer. However, it sounds like people low pass them even lower than that to avoid any potential noise. Has anyone had problems with hearing the clarks with frequencies as high as 30 hz.

I pretty much have the same objective as you. My home theater is by no means elaborate, I have probably spent the most money on rackmount gear than any other piece of equipment, although this will defenitely change when I am finally able to upgrade my plasma. I am not looking for the best solution that money can buy either, I just want to get my feet wet and go from there. I too and going to get a pair of the clark silvers as soon as I have the money saved. As far as interfering with the sound from the the subwoofer, I think it would depend on what you have the tranducers attached to. They are designed to create audible noise when attached to a large surface like a window. I am not sure there will be that much audible noise when attached to the frame of a couch. I also think there are instances when you would want them to compliment the noise from the sub. Last time my brother was down, I was watching him play some call of duty and I was thinking how cool it would be to be able to feel the tank shooting and getting blown up, oreven the vibrations of the tank driving around. In this situation it might be better to have the crossover somewhat higher. I am not sure about any of this though as I have not had any experience with it yet. I'll just have to see how it all works and adjust my expectations and equipment accordingly.

The Clark Silvers are pretty reasonable from parts express right now. They also put an insert of the seismic sofa project in their most recent flyer they sent out. It is more detailed than what is on their website. Here's a link to it.

Thank you for the information everyone.
