Cabinet tuned 4acoustic guitar was created by Electrical_EngiNerd
Building a custom PA/Acoustic Guitar system for coffee shop gig portability and size. Anyone have thoughts or ideas for an array of 6 mid-bass speaker cabinets holding 1 each 6.5" mid-sub drivers? Would like to tune the enclosures to the sound characteristics of the acoustic guitar. I found a post on a guitar builder website that most steel stringed acoustic guitars have a resonance frequency of 55Hz. Looking at doing a simple ported tuned to 55Hz = fb. Sealed may be more accurate though. Any info or opinions would be appreciated.

Plenty easy to design a reflex box tuned to 55Hz. I would think for an acoustic you would want also to use something for the treble. With electric guitar amps setups they generally don't use tweeters or compression drivers because the heavy distortion would take them out fast, but with acoustic guitar, you want to hear that clean tone, so I would either use a coaxial speaker or two way with a comp driver and wide dispersion horn. To design the box, I would recommend Win Isd or something along those lines. Here is a simple calculator for Reflex boxes which is web based. I have used it with decent results.

Lots of other useful calculators on there too.
