Last night I watched Paranormal 4 with my daughter (even she thought it was bad) and we could hear the transducers at times. The movie had a loud low frequency hum during certain parts that caused both transducers to rattle while...

So, the 220 feet have been installed. I would say that they made a marginal improvement over the smaller feet, but that could just be my brain trying to justify the $60. Next comes the reciprocating saw; with luck I will get good shake...

The top of the riser is glued and screwed to the joists, so no joy on isolating just the top. Also, I don't think that the plywood is strong enough to hold the chairs. Knowing that there is a lot of pressure applied to the rear of the...

Also, I heard back from Marvin at BK and he suggested: 1) Try adding another transducer. I can try this, but it takes some work to remove from the couch and install in the riser. 2) Try the larger isolators. I will try the 220s. 3)...

Has anyone tried mounting a BK transducer on its side? If I were to use soft isolators and mount the transducer on its side - thru a joist - would I get the desired result? The whole point of the transducer is to move up/down, it would...

I agree that stiffness is a big issue. I experimented some with different amps and configurations last night; there are a few other things going on. First, I don't think that the banana plugs were fitting into the speaker binding posts...

Thanks Craig. I wanted stiff joists so that the chairs, which mount on a single leg, would not cause the riser to deform. I think that I overshot some. I am working with Marvin at Guitammer and am a little worried that he will...

The whole thing actually sits on rubber isolators, so they won't hit the floor, but the platform IS very rigid. I could cut down the "joists" if more flex is needed...

I posted this in the construction forum before I realized that there is a Transducer forum. Posted here as well. I mounted a buttkicker LFE Transducer (from a Buttkicker LFE kit) beneath a 4’ x 5.5’ riser. The riser is constructed of...

Thanks. I'm a little worried about the capabilities of a single unit as well. Was planning to test the riser with an existing transducer, but a deal came up that I couldn't resist and I ran out of time. Switching the trasducers is...
