Friends,
I have following query which i trust you will answer.
This is re room dimensions, or specifically 'golden ratios'.
quote "As it turns out, if you design a listening room with exactly the right dimensions, you can spread out the high and low pressure areas so that anoptimum sound field is obtained. Roy Allison, founder of RA labs and Allison Acoustics, has written extensively on this, and in his paper "The Loudspeaker/Room System" he examines some of the "golden room ratios" developed by researchers L. Louden and L.W. Sepmeyer. These golden room ratios are the result of calculating the modal distributions created by low frequency sound waves, and striving for the most uniform distribution. L.W. Sepmeyer's ratios, in particular, have been highly utilized. Our table illustrates the three famous Sepmeyer room ratios that have formed the basis for hundreds of listening room designs over the last 30 years." unquote
(ref:
Home Theater Room Dimension Formulas & Calculator)
The room dimensions may not be always exactly the same as golden room ratios, in which case, you opt for a AVR which has 'room correction system' which senses every speaker and adjusts itself based on the feedback . Now, these kind of systems are quite costly.
On the other hand, have a good AVR which is less costly without 'room correction system', tune the speakers while setting up HT by an expert, and leave it at that.
The third alternative, of course, is to modify the room to golden ratios, this alternative may not be practical all the time.
How important are these golden rations anyway???? (Sepmeyer's ratios H:W:L = 1:1.14:1.39 or 1:1.28:1.54 or1: 1.6: 2.33)
