Sound Quality

Updated: Aug 4, 2019

I had to create a speaker which was portable, loud and sounded good. My speaker building over the years focused on achieving a balanced sound across the frequency spectrum. As any speaker builder knows there are many factors that color the sound you are trying to achieve.


The BBOX I designed needed speaker drivers that could deliver excellent sound and volume for a relatively small speaker enclosure. My targets where to get a frequency response of 30 Hz to 20,000 Hz +/- 6dB and a high SPL.

I had carefully chosen drivers that matched what I wanted to achieve. A Dayton Audio 10" subwoofer SD270A-88 and for the mid range Aura NS3-193-8A 3" Extended Range drivers. To achieve a crisp top end I went with Dayton Audio ND16FA-6 5/8" Soft Dome Neodymium Tweeters. All drivers provide a nice flat range and are well respected by other audio makers out there.

The relatively small sealed enclosure design meant I would have punchy bass but I would need to boost the frequencies below 55 Hz.

To achieve the balancing of the speaker enclosure frequency response I used a Digital Signal Processor to achieve this. I used a reference microphone to analyse the speakers frequency SPL levels and adjusted the equalisation precisely and accordingly. In the end I have a great sounding speaker that rivals many other commercial speakers :)
