Devine BA15 15-inch Woofer
I'm very pleasantly surprised. A huge positive. I bought two speakers. They arrived two days later. Unfortunately, one was damaged. The basket was bent. After reporting this, I had a new speaker two days later.
I bought these speakers for my open baffle + biamping + DSP project. After measuring, I was also surprised. They were exactly what I needed. Importantly, both units have very similar specifications. At this price (and they are four times cheaper than, for example, the Eminence Alfa, which they beat hands down in a DSP system, cone control, and detail), there's no competition if you're building a system with DSP and have the ability to boost the low frequency range. I'm including the speaker measurements, which I took in amateur conditions, outdoors, without a baffle.
