Transducers are now working better with help from Milo. Using 8Ohm Amplifier for 4Ohm Transducer. There is concern they may overheat and cause speakers to blow. But tests were fine. The sounds will not be constant so perhaps it will not cause a problem.
The 4 Ohms HongXing Amplifier wasn’t loud enough for the Monacor Bassrocker Transducer Speakers.
We switched to the 8 Ohm, Vision AV-1301 Amplifier. The Monacor Bass Transducers are 4 Ohms, so there was concern we could blow the speakers. It seemed to work out fine though. A stereo pair of Monacors would be 2 x 4 Ohms. Here I am setting up two Vision AV-1301s, in order to run a stereo signal through 2 mini-speakers and 2 transducer speakers.
Current plan is stereo recordings I settled on yesterday. L & R split across different parts of the venue in conjunction with a headphone splitter taking the same signals to two small tweeter like speakers. Hoping that the transducer can provide the presence and bass of the footsteps and the tweeters can pick up more high end reverberates from the space. Placement tomorrow will be based around the installations downstairs, as to not take over from these spaces. Milo suggested somewhere around our working office. Which I think may work… Right Now I am picturing placing L Transducer & Tweeter at G Floor and R Transducer & Speaker 1st Floor. I was initially hoping to place one transducer on the beam through the hallway of the exhibition upstairs. But it’s pure brick and very solid, resonance works better through a more hollow surface. It sounded and felt like footsteps when it was placed on the floorboards downstairs. So I am thinking placing the transducers on the floors may be the best move. Part of me would like to create the illusion of overhead movement. So I guess the transducer on 1st floor could achieve this. I wanted to experiment with a train sound which would occur very rarely.
