"I had admired his purposeful approach to audio design since I was in design school. His form always follows function; He makes things what they need to be and just that."
"I was considering a shift in my process, using domestic production to have more direct feedback when manufacturing. Having the Grovemade guys approach me was perfect timing."
Joey then gave us a little background on wood speakers. He explained to us that manufactured wood products (MDF and plywood) are the most common material for high quality speakers because it has good acoustic properties, is consistent, and is relatively inexpensive. This lends itself naturally to cabinet style construction. However, the weakness of the cabinet style are the many parallel surfaces which allow standing waves to form, causing distortion. Designers use techniques to compensate for this problem but it involves adding more passive components to the signal path further degrading the quality.
"Years ago I had seen the incredible craftsmanship behind Renovo’s cycles and had a feeling that it could be applicable to our scale somewhere down the road."
B: The CNC machined enclosure has no parallel walls and no flat surfaces. Like a concert hall or recording studio, its internal geometry eliminates standing waves that cause distortion and time smearing. This is particularly important because the driver's extremely thin metal diaphragm, which is necessary for its performance, would otherwise let these standing waves and reflections reach the listener.
C: The back-loaded horn couples the driver's back wave with the air at the lower frequencies, reinforcing the speaker's bass response.
"Showing the process of manufacturing rather than hiding it turned out to be one of our favorite design details."
"I adjusted the internal geometry to reinforce the bass response while being careful not to sacrifice clarity in the midrange and highs."
Overall, the design process lasted about a year from beginning to end. Combining forces with Joey Roth enabled us to create an amazing system beyond what either of us could have done on our own. Stretching beyond our individual potential by working as a team was invigorating. Where can we go next?
