Ok, so just trying to get some topics going on this forum and wanted to share an experience I had this past week. So I have three vehicles in the family all with two way active front stage with ported subwoofers. This vehicle has the least expensive equipment of all of them but still nice low distortion stuff. If anyone has a decent amount of tuning experience you will eventually find out that tuning a two way is somewhat difficult. My wife’s Sienna van has had the same tune in it for over a year and I’ve actually come a long way in tuning skills since I tuned that vehicle. My wife was complaining of lack of bass from the ported Alpine SWS 10 so I took out the microphone and REW and started measuring so I could diagnose it. Turns out the subwoofer somehow was 180 degrees out of phase with the midwoofers and the tune was all over the place. I spent about 2 hours tuning and completely redid the tune from scratch. I thought this vehicle sounded decent before but damn it sounds fantastic now. I sat in this vehicle afterwards just sampling song after song and thinking to myself it should not sound as good as it does. My wife has already commend on how much better it sounds too. All this too when I was starting to think about maybe upgrading some of the drivers in this vehicle but now it sounds so good that there is no need for that. There is a lot of hidden potential in tuning that should be explored before you blame the equipment. It makes a huge difference!
Also, these SB Acoustics SB29RDNC tweeters are just fantastic low distortion tweeters that work great off axis in dash locations and can cross very low. I have these at 2200Hz now LR4 and they could probably go even lower.
