Post Subject: sub horn configurationsPosted by minim on: 2/11/2007
In one idealistic configuration I envisaged for myself, for a situation where cost and practicality no object, the basic room shape was pentagonal, with the facets ot the pentagon curved inwards to eliminate parallel reflecting surfaces and simultaneously create walls for the five horn throats thus formed for the line arrays (or electrostatic elements) at the five corners.
The ultra LF horn would be mono and form the ceiling/roof, comprised of five curving panels and culminating in a driver mounted at the tip of what would appear from the outside to be a steeple, enclosed in a suitable way of course.
Seems to me that with a barn there would be enough vertical height available to accomodate an uncompromised straight horn and if not, the extra length could either protrude through the peak of the roof, forming a steeple-like thing that might come in handy when you establish your audio worshipping cult, or else be folded around in a single bend.
Alternately, being out in the country, you could for a lesser expenditure, if your time is worth anything, buy 8 suitable 15 or 18 inch drivers, 4 to a side, and mount them in the walls in an enclosure vented liberally to the outside, so that they are in effect infinite baffle mounted.
Linearity of response through the driver resonance and crossover itself could be achieved with e Behringer DCX 24/96. If the low pass frequency chosen was 50 Hz or lower, the outside sound would really be negligible except for certain videos (explosions, helicopters) and 1812 Overture equivalents.
I think that the IB configuration must be added to your list of one potentially unlimited sub bass enclosure, Romy, namely the sealed box.Rerurn to Romy the Cat's Site
