### ⭐⭐⭐⭐⭐ Review
*by T***N on 2 September 2016*

This speaker is primarily intended to be a pro audio speaker, but I bought it to use for a dual purpose guitar and bass cab. I was looking for something like an EVM12L and came across this guy's big brother, the Delta Pro 12A. This one (the non-Pro) doesn't have quite as flat of a response, with a noticeable bump in the 2k-4.5kish range - which many people consider desirable for guitar. It's also 5 pounds lighter and roughly half the price. Anyways, it sounds fantastic for guitar. It's a fairly transparent speaker, and is quite articulate and responsive without sounding "hifi". It's quite smooth with high gain, and doesn't get muddy even with a lot of bass in the signal (low tunings sound beastly - Drop A thunders through this thing). Cleans sound great, with no noticeable volume spikes (some guitar speakers seem much louder on some notes than others - none of that here). As a bass speaker, this works great as well. Of course, the lower you want to go, the better your cab design will have to be. Mine's a bit of a compromise as my main instrument is guitar and I designed the cab primarily for that, but the cab still works great for an old school (classic rock) bass tone with this speaker. I'm sure with a cab that's tuned and ported to put out the low end you could get a more modern bass tone out of this speaker.
