This thread was supposed to be for me to be lazy schooled!lazy subbed
Think of it this way. If you have varying output from the source (speaker) that is frequency and axis dependent that makes an already reflective environment worse. The beaming frequency is around 2KHz in my case. By crossing below it, the response is more linear.So what benefits do we get when we keep the speaker out of beaming ? Won’t the response be much different when the driver is mounted ?
I’ve heard people getting great results with a wideband. The wide band has to be on axis though to get the full benefit.I recently traded out my SI M25 (1.5 inch diameter) tweets for the AF gs25 (2.5 inch tweets). This allowed me to run a much lower crossover so beaming from the 6.5 midbass is no longer an issue but now with a 2.5 tweet, I have to consider beaming above 5k or so. I have them mounted in a prototype mount to get them more on axis. Frankly, I am the only one in the vehicle that really cares about sound so a driver's tune is good enough. I think I do not have them on axis enough at this point even though the RTA looks good. If I scrunch down and get my head more on axis, the upper end brightness returns. I definitely notice that much of the human vocal passband is no longer just sounding good in a small region around the drivers head, but if I stay two way, it will be that the upper end sparkle is restricted to that point.
I wonder if three way would just be better, boy this has me spinning in circles and I am tired of mounting and retuning and whatnot for now. I prolley could mount both the gs25 and the m25 flush to the door panel right next to one another, without any angled mounts. What is holding me back is the eventual loss in global filters; I have the amp channels, dsp channels, and wiring ready to go though.
I have read the same and it makes sense. My gs25 is not quite on axis (on the drivers side) yet. I will try fabbing up a new prototype and see where that gets me. It is quite an improvement in sound when I move my head about a foot lower than driving position. All this is said with a mediocre, quick tune and not even really sure where I want to cross the 6.5 to the 2.5 at this point. I am trying a 800 Hz acoustic crossover at this time, but maybe makes sense to go even lower.I’ve heard people getting great results with a wideband.
