transducer mounting 2020

Thanks for this great video. Could you pls make another one showing the rest of the system, like how the amp and control box all get connected?

Thanks again for all your help!

Hi thanks for sharing that very simple way to install the transducers You just skip the most important part what amplifier are you using We’re do you connect the transducer wires to,to make them do there job

[@quantumresonance5309]

We use our own custom amplifier and nuetrik connections to our amps. Audio retailers like parts express sell these transducers and can give you tips and proper recommendations for amplifiers

[@quantumresonance5309]

We use our own amplifiers that are custom spec'd to our needs. A 200-350 watt amplifier should be sufficient for your needs when running a 4 ohm load (the ibeam are 4 ohm not 8 ohm like most home speakers). Don't get fancy with the wiring schemes unless a professional is wiring up the system- the impedance could become unstable for a home amplifier. Finally, use low pass filters for the transducers. They don't need to play all the frequencies you are hearing- just the low end stuff. You can buy small amps that have built in crossover networks that will run the power you require. If you use a 100 watt amplifier, you run the chance of damaging the transducer due to clipping of the audio signal.

I have the same question, feeling the need to see the rest of the system not just the transducer. The amp is just as important, and how you connect everything, since I’m new to this. Above you said that 200-350 watt amplifier should be sufficient, and you also said that a 100-watt amp might clip and damage the transducers. So, which is it? 200-350 watt, or 100 watt?

Great video. Can we apply e6000 to the entire base of the transducers to make sure it holds better? I’m not sure how thick the wood is on my table, and I’m concerned that gravity in the vibrations will make the transducers come off overtime. Can you think of any disadvantage to gluing the entire transducer?

[@quantumresonance5309]

Hi Don, the problem with using a silicon based glue is that it needs air to dry and by applying it to the based, there is no air. Second issue is that transducers work best with a direct contact to the surface ie., no rubber like glue between the transducer and the mounting area. I have never had a transducer fall off our systems (particularly with the Ibeam at 10 screws each) when using the e6000 in this way. If you need more adhesion, consider a 2 part epoxy as the glue that is sandwiched between the ibeam and the mounting surface. Just know that you will damage the table if you remove the ibeam later. I have also used an aluminum substrate between the table and the ibeam. The aluminum gets screwed and glued and then the ibeam gets mounting to the aluminum plate with self tapping screws and e6000. I don't use steel plates since it will cause the spider inside of the transducer to pull to one side more than the other which causes it's own problems. Finally, be aware that the magnets are very strong so pacemakers will stop working when near them.

Thank you so much for taking the time to reply! I will be using Dayton Audio transducers, however, I will mounting six of them. I am launching a VAT business, and this will be my primary table. I’m not concerned about ruining the massage table. However, I am definitely concerned about them loosening or making weird, vibrating noises,, etc. I have some colleagues that have had good results, applying a silicon caulk to the entire back of the transducer. I was going to go that route before I discovered your video. E 6000 to me seems stronger than the silicon caulk. Maybe I should use the silicon caulk on the back and the E 6000 around the sides. Do you think that would be a good solution? Thanks again for your insight!

im assuming you are using the BST-1 from dayton audio. They make a new version called the BST-300 which is far stronger which means you can use less transducers. The BST series use a foam pad in the middle which i am not a fan of. They also only use 4 screws which is a problem in the 1/8" thick wood laminate that is found in massage tables. For a serious glue, use the water activating wood glues that gorilla and other companies use. It will permeate the wood and create a far stronger bond. When used in combination witht he mechanical fasteners like screws, it is a great bond. The moving mass of the transducer in combination with the coil size and other factors make up how low a transducer can go. If the transducers you are using does not have a large moving mass, then you just won't feel the low end the same way. If your using 6 transducers, i'm imagining you are running a series + parrallel connection for a 8 ohm nominal load, you will have more energy for the given frequencies, but they still may not hit the low end. I would also be a bit concerned of dead spots and high spots just like in a room, but i haven't tried 6 at once. The reason for us using the Ibeam is that they have the most accurate and fast response while hitting well below 30Hz. We have tried all the transducers on the market and have burnt out 3 of the clark, 1 butt kicker, 2 dayton models. None of the transducers feel as good as the ibeam. @@donc4238

Wow, thanks again for the info! Yes, I have 6 of the BST-1 and 2 of the BSA 200 amps. (I decided on 6 because VAT expert Kate Kunkel recommended that.) You have me concerned though that you "burnt out" the Daytons. If you wanted to use what I have, would you recommend your method with the E6000, or the water-activating glue ? Or some combination like both silicon caulk and E6000? Thanks for sharing your knowledge! Do you have a link to your business?

[@quantumresonance5309]

You can run a single BSA200 with three transducers per channel in parallel which would give you 2.67 ohms at 87 watts. The amp is rated at 110watts @ 2ohms so it is just enough power for it work. The amp will run hot so don't stuff in a cabinet without forced air. With the BS-1's, they are rated at 50Watts and it helps to have more power available for the transient spikes from the music. The parallel wiring will help keep the amp from clipping when you run close to max volume. if you run a series/parallel setup, you are looking at around 40 WPC at 5.3 Ohms for 3 transducers on each of the 2 channels. 40 watts per channel will cause the amp to go into clipping at it approaches max volume which will damage the transducers. Transducers burn out when they are run continuously at close to max power. The transducers can also burn out when they are driven at clipping which is a massively distorted signal. The music we create has lots of low end information so it overworks the motor of the transducers, heating up the enamel of the coil, melting the enamel and causes shorts, and enough gumming of the parts to seize the coil up. This is why we are running transducers with higher power rating and faster response time. Personally, i would use the water glue Here is a good website for wiring configurations and impedance information soundcertified.com/speaker-ohms-calculator/ Our website is www.quantumresonance.org BTW, the BS-1 make 30Ft.Lbs of force or 180Ft. Lbs. for all 6. The ibeam create 220Ft.Lbs for a total of 440 Ft. Lbs. for 2 transducers. Massive difference in energy transmission. @@donc4238

[@patricialink8935]

Can you please send a list of what we need to convert our table? Or do you have a pkt we can buy? Ty so much

[@quantumresonance5309]

Hi Patricia, Thanks for the inquiry. We make a custom system exclusively for the crystal bed which is a complete package. The system uses specialty components that are only available in professional sound use. Your best bet is to reach out to inner solutions. They use the same transducers as we do but are designed for off-the-shelf audio parts. innersoulutions.com
