[QUOTE="Silas Pradetto, post: 71987, member: 34"] Re: Reasonably Priced Large Format Line Arrays Asymmetrical design is not inherently bad, but in the vast majority of asymmetrical line array boxes I've seen, the crossover point just happens to be close to the 1/2 wavelength spacing of the drivers, meaning there is NOTHING off-axis. Check out the polars of the NXL23A - it's awful. I actually like having speech intelligibility more than 10 degrees off-axis. If the crossover point is low enough this isn't an issue (drivers can only be located so close), but most of the lower-end boxes don't seem to pay attention to this huge shortcoming. Maybe this is why I hate VRX so much? PS- a symmetrical line array can have this same issue, but for some reason, I don't see many boxes that have it? PPS - my new HDL20-A boxes have a small narrowing of the pattern around 600Hz because of the spacing of the 10" drivers, but in many cases, I wouldn't mind less pattern in that range; it is a problem area in many rooms in which I work. Off the top of my head, 60 degrees is as narrow as it gets. PPPS - both Meyer and ADR audio have asymmetrical line arrays, but both get around the pattern issue by using VERY low crossover points.
