Hello,

I need to buy a sub for the LFE channel in my 5.1 setup. I need to know if
this channel is already crossover'ed or do I need to buy a crossover for
this channel. If so then which LPF to use here.

Many thanks for your help

It depends on what is providing the LFE output. Most AVRs and
pre/pros have bass-management and LFE is usually limited to 120Hz.
You will need an amplifier or and amplified subwoofer, since most of
the LFE outputs are at line level.

So, what else is in the system?

Thank you,

The LFE is the .1 channel as commonly referred to in DVD Video (movies). In
case this channel is already limited to 120Hz as per your reply, custom
crossover is not needed. Am I assuming correct?

Probably but you still have not told us the electronic device which is
being connected to the subwoofer!

DVD player's digital out goes to Kenwood receiver. 5 channels out of the 5.1
channel are amplified by this receiver and outputted to 5 Bose speakers. The
LFE is out as pre-amp.

Now If I buy a powered sub as you mentioned earlier, things are OK since the
powered woofer already has the crossover button for various Hz. But I have
an amp (no filter) and will buy only the woofer to complete the setup.

Thanks. I am just a reply away to complete the setup :-P

A powered sub, either without a filter/crossover (as I use) or with
one that can be bypassed or defeated will be sufficient.
