[QUOTE="Buck, post: 8794724, member: 591582"] You say it’s a 3 way? Are you having cancellation issues? I would make sure your 3 way active isn’t having issue with phasing and woofers crossing or playing the same frequencies and being out of phase with each other. The location and angling of a 3 way might matter a bit more than a 2 way, because of how the speakers divide the frequencies up differently. I would maybe post up the playing bandwidth of each component of the 3 way, how they’re crossed over or limited from playing outside of that, the db/octave slope, and the location and angling of all of the speakers. I’m not the most familiar with active setups, haven’t hardcore researched or experimented with it much. I’m just looking from a raw sound perspective. What I’m saying is imagine if you had all of the speakers in the 3 way grouped together like a typical 2 way component would be with built in tweeter, where all the axis of the individual components are linear/truly parallel and in phase. Now if you separate all the axis and angle them differently from each other, that in itself could cause issues, especially if any angles are weird and if there’s any phasing issues on the electrical side of things. I know staging matters, which is angling. Sound becomes significantly more angular as you move up in frequency, so the locations of woofers can put you out of the “beam” of a tweeter, for example. On the lower end, if speakers are all in a door, you could have door-related resonance issues. You maybe want to consider sealing the midrange and midbass, maybe gain some control over the rear wave resonances, if they aren’t already like that. Hope maybe some of that helps. [/QUOTE]
