Hi guys,

I was recently caught up with a friend who is planning to upgrade his
main speakers to one with responses between 20Hz-20KHz.


:-)

Nice theory......

(The 'audible range' is more 16 Hz - 16 kHz, btw....)



I was told that one of the sales guys mentioned an alternative - Buy a
good pair subwoofers to support the pair of lovely Whatmough (40
HZ-20KHz) mains my friend already has.

I was wondering how could subwoofers be connected to a two channel amp
as it is primarily a 5-channel equipment. The amp is a 20yrs old denon
with phono inputs, CD direct etc.

Is this sales guy just bull-****ting or can this really be done?


Yes, see:

For how it goes....

But you don't need 2 subs, the sound is omnidirectional at those
frequencies - apart from the unnecessary expense, using 2 subs will give no
benefit and might well allow problems to creep in if they are not perfectly
matched...
