The THX standard for setting up FLOORSTANDING speakers is NOT an absolute standard that applies to all siutations and all ppl and their personal preferences.
In reply to:
it's highly unlikely that you'll benefit by lowering the 80Hz crossover. Your center and surrounds would be down considerably at 60Hz, which would lead to some weakness in that mid-bass area.
There is no basis for this statement.
If a surround speaker such as the QS8 has a lower range of 95Hz, then lowering the receiver crossover from
80Hz changes nothing. The QS8 would
already be down several dB at 80Hz let alone what it would be at 60Hz.
Weakness in mid bass?
How?
With the mains set to large, the mid bass is still very prominent. With a crossover at 80Hz for surrounds and mains set to small, the only thing playing mid bass is the subwoofer. With the mains set to large, you could potentially have BOTH the mains and the subwoofer playing mid bass sound depending on where the subwoofer crossover is set. You WILL get less boomyness from the mid bass (tighter bass) which is a sound that i prefer.
Come on JohnK, the fear monger attempt at getting ppl to only use a THX method of setting up their home HT/stereo system is sad. Both methods of setup have merit.
In reply to:
extensive tests by THX and confirmed by Nousaine among others showed this to be the best compromise, being high enough to take a significant part of the load off of the speakers and the receiver, but not so high as to make the sub easily localizable.
Load off the receiver. This is an old discussion.
You have to consider those who do use separate components with their processor as well as those who do not crank movies to the 100dB range or beyond. To date, my less than top of the line Onkyo is powering 5 speakers and i've had no 'load' problems reaching 90+dB levels. No clipping and no protection shut off.
This argument about receiver load becomes invalid in many situations.
Sub localizable?
Lowering a crossover doesn't change that any. Regardless of the speaker, lower frequencies are not localizable.
For anyone who has a dual use for their sound systems, both music and HT, and do not like the boomy presence of a subwoofer for music, use the mains set to large if you have FLOORSTANDING speakers and disregard the THX standard.
The standard is ONLY a recommendation, not a an absolute rule.
