What are peoples opinions on angling the mid drivers? I am setting up a Patrol WGN which is a high vehicle with the position of the mids in the bottom of the doors.

People talk about angling tweeters at the head rests of opposite seats, but what about the mids?

Thanks for any opinions or experiences!!

I can't install or try anything yet so I may as well talk about it!!!

In short, mids aren't as directional as tweeters, which is why they do not have to be angled as much. That's not to say you won't have to angle them, depending on how far or high you are from the speakers will affect how severely you will need to angle them.

Several factors are in play with mids including on/off axis response, distance from opposing mid, and freq range they play.

Phase issues are common with mids that are not angled, as the wave length of freqs played by mids will often result in some destructive standing waves and also some constructive standing waves. Without getting into it too much, the bottom line is that just using as little as 15 degrees from vertical of angle is enough to avoid standing wave issues.

Wether more agrressive angling will do anything depends on off axis response of particular driver, or more correctly, lack of off axis response.

The only way to find out if more agressive angling will be of benefit is to try it, but using a little angling will be of significant benefit and so well worth trying. More agressive angling may intrude on leg room and so take into account livabilty of this before going too hard core with pods.

Anyway using slight angling(15 degrees) towards middle of roof (like tweeters) may be of benefit, but going for more angle may or may not make a difference, and only trying it would tell.

Excellent, this is just the information I needed. I was going to angle them radically, but I was worried about water and dust ingress. But I knew I should get some angle on it.

Great info, do people incline the infill speakers/splits in the rear?? This would suggest they should. I was going to anyway, to angle them up a bit.

Take a look at pics of T-Bro's pods for an example of "extreme angling" hehehe

I don't know what the difference would be without such an incline, but i love it just the way it is!

yeah, in a 2-way setup, you would expect the woofer to have to play up to around 3kHz. and frequencies above ~1kHz are fairly 'directional', moreso the higher you go. so IMO it's worth angling the woofer of a 2-way setup. in a 3-way setup, the midrange speaker will definitely benefit from angling, and given it is usually relatively small, should be fairly easy to achieve.

in building an angled pod, it's only worth doing if you do it properly. no point having a 'leaky' pod or a loose-fitting speaker. so ensure it's air-tight and provides a solid mount for the speaker, and you will achieve best results.

in my setup, i've retained stock door trims and grills, so i was limited to ~15 degrees of angling. i never did a comparison between angled and not angled, but i figure it helps.

good luck
