Tone Buck Two’s
The Tone Buck Two’s were built with the intention of having nice home entertainment speakers. I wanted a aesthetically pleasing good sounding set of speakers. I prioritized SPL and size. With my typical listening in mind I was not very worried about low frequency extension.

- Low distortion

Scary Stereo
Scary Stereo was born from my wish for big scary tower speakers. I wanted nice home theater speakers for my living room as big as I could possibly get them. When thinking of how to use all the surface area, I decided to paint them with chalkboard paint. As these speakers are for listening forward I prioritized low-frequency extension with the large size of the cabinet as well as 15″ subwoofer drivers. My subwoofers pair with my mid and tweeters to make a transparent sound stage reaching above 20k.
