As it is, just an un amplified voice in the room is already very wet. Obviously we want to avoid exciting the reflective surfaces or intelligibility will suffer. This room is stone, wood, concrete, glass and plaster. Any system is a compromise so the goal is to optimize the system so that everyone has even volume and even frequency response without comb filtering and while trying to avoid exciting the room.
I’ve spent countless hours thinking about this project, drawing pictures, measuring angles, asking my mentors questions, etc…Īt the end of the day, there is no such thing as a perfect sound system design. Recreating an analog EQ setting in a digital plugin I’m about to email McCauley Sound who provided the 15″ woofer for the Renkus Heinz TRC151/9 enclosure. I’ve written Renkus Heinz engineers to verify expected results. I’ve written Eminence to verify terminal polarity on the HF driver. What do you do when the measurement is cut and dry?Īsk questions. Loudspeaker Design Cookbook 7th Edition – Vance DickasonĪs I have been trying to verify that the TRC151 pair that I have are back to factory spec, I have realized that some times the measurement results for even a single cabinet as simple as a two way passive design can be overwhelming. Some books I have come across that seem worth having in your library are as follows: How does one learn about speakers, speaker design, speaker testing? We must verify each part if we are to know that we are making things better and not just spinning our wheels. Obviously we can’t leave it to chance that a system is properly configured.
“Isn’t the red terminal on a driver positive?” Maybe. For example, something as simple as replacing a blown driver may lead to the replacement driver being reinstalled out of polarity. Certainly if you’re dealing with a system that is older, there may have been many opportunities for something to be done wrong. One could assume that for an installation involving new speakers, they would all be functional but this would be a dangerous assumption.
I have been refurbishing a pair of Renkus Heinz TRC151/9 speakers for a local venue and during the process have realized that in order to understand, design and optimize a sound system (made up of individual speakers), one must understand how a speaker works, why it is designed the way it is and how to understand what goes wrong and how to resolve it.
