Time alignment (Oris Horns)

Hi Stefan,

My question this time is about time alignment: How are the horns
supposed to be positioned to optimaly integrate with the bass. Are the
voice coils supposed to be "in line" or should I place the horns so that
the horn mouth is in line with the bass bin baffle? Why? Please explain
this to a curious lawyer :confused: .

Not just time-alignment is important but also the filtering used if you are heading that way. What the best compromise will be depends on the filtering where things can be optimal in phase and timing but needing many components to make that work...

Sometimes using less components is more... Remember, everything in this speaker world is a compromise..

With the filters used for your system (none on the AER and approximately 18dB on the bass) gives the best result when the horn mouth is in line with the baffle of the bass system and the bass or the Oris horns connected in the opposite phase.

It is not just about coils physical aligning, also about delay and phase turns created when filtering. Especially filtering the bass and the "slower" reaction of the bass driver give a certain delay compared to the AER.

I hope this helps?

Bert
