Connecting subwoofers to a 2-channel audio amp.
 

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.

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?

cheers

Max

** So you have never heard of an "active" sub woofer ??

Use Google - there are hundreds of them on the market.,

Hi Phil,

Yes I am aware of 'active' subbys and have a couple at my place.Al of
them however have been connected to my Marantz 6.1 integrated amp .

In my friend's case the only two speaker outputs are left and right.
Hence my question how do I get subbys to work on a two channel amp.

Cheers

** You connect them as shown in the operator's manual !!!!

Could be linked by RCA leads to the pre-amp outputs on the amp or via the
speaker outputs.

Commonly, active subs are simply linked with short wires to the existing
speakers.


BTW:


Do NOT post in "mid air" like this !!!!!!!!!!!!!!!!!!!!

ALWAYS quote the post and poster you are responding to.

Graham,

You mean in series with the mains?

They would go in parallel but you need a crossover somewhere too.

I suggest you listen to the nice man in the shop. He seems to know what he's
talkking about.

:-)

Nice theory......

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

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...
