Tweeter below mid-woofer

Take a look at Loudspeaker Design Cookbook by Vance Dickason 6th. edition.
This is an excellent starting point for understanding Loudspeakers. This book may be a your local library or can be purchased at Old Colony Books

Also look at North Creek. They provide an overview and a free booklet.

Kind of a funny question for me. I was recently thinking of starting a thread about imaging, soundstage and driver arrangement. Your question obviously touches on all of these subjects. This can be a very complex subject, so we'll try and keep it simple and go from there.

If the drivers are on a flat baffle and the designer has taken no steps to simulate "time alignment" in the crossover, placing the tweeter below the mid-woofer will result in imaging that wants to project upward. As such, these type of speakers will typically work best if the tweeter is slightly below ear level. The opposite is true when using a more conventional tweeter above mid-woofer approach that we usually see. That is, the tweeter should "typically" be placed at or slightly above ear level. In a three way design with the tweeter mounted between the woofer and midrange, things can get pretty weird due to comb-filtering.

When using stand mounted monitors, buying a cheap pair of "adjustable" stands will help you to find their optimum height, but you also have to remember that height affects frequency response / tonal balance. As such, trade-offs are involved much like the rest of audio.

As far as your specific situation with the floor-standing PSB Bronze's, you might want to contact the manufacturer and discuss your thoughts. Otherwise, if you are happy with the Paradigms but just want more "oomph", have you considered subwoofers ? Sean

Right now I have the MK3's crossed over @65hz.I find that the single 6.5 driver compress's around 80-90 db.I thought that maybe a good two and a halfway design would work.Crossing over @ 80hz is out of the question.It sounds like hell.The mini's sound so good I may just live with it.Love those textile dome tweeters.

It's quite evident for me since there's no perfect tweeter.

I've done experiments with different tweeters from different speakers(yes, driving only tweeters with my almost perfect musical hearing as a former musician) and lemme tell ya that every tweeter is dirty as hell and needs correction one way or another.

In terms of wave propagation to the listening position tweeter bellow the woofer DOES make sence since it compresses the tweeter's imperfections and makes on the cetrain distance a clear and nice natural sound believe it or not.

Marakanetz: When "auditioning" various tweeters, what do you do about the tweeter trying to reproduce out of band information ? Sean
