In the Thread: Driver Alignment, and Where to Draw the Line
Post Subject: Measured ProgressPosted by jessie.dazzle on: 5/27/2007
Thanks very much Romy and Dan for the input.
With the exception of a structure to locate the horns, I have all the tools necessary to make the measurements.
Though this is all happening in France where DSPs and TADS rule* (see note at end), all filters are first order passive, non-digital.
BTW, I am using a 180Hz lower Mid-Range horn with the S2 driver filtered to receive between 800-3200Hz (first order). Working within this frequency band, I hear no reason to use a steeper filter. It is really clear why Romy calls this the fundamentals channel.
I don't yet have frames to hold the horns in place, but I've been working on a design.
This frame would allow some fore and aft adjustment of each horn. With a bit of careful planning, the driver will end up in the center of the range of adjustment (this is what was behind my question in the above post).
Romy's comments on "axial rotation" of the horns (meaning in this case, angling the horns) has me thinking. I had planned to build in a vertical tilt adjustment for horns located near the floor and ceiling...
I would be interested in hearing more if anyone has thoughts on this subject.
In any case, in this house the 45Hz Mid-Bass horns will have to be angled down from above ; their drivers will not be aligned with the rest of the system... this may eventually be a reason to move to a new house.
Thanks again,

Oh yeah : Why have the French so embraced DSP technology? Simple ; if you had a French mother, you too would likely embrace DSP technology (I am completely serious here).
I am leaving out a lot, but the rusult is as follows :
These people are superbly able to grasp complex concepts in isolated blocks... And superbly unable to put into practice the concept of flux.
They see and act only in blocks!Rerurn to Romy the Cat's Site
