Lfe

[ronaldo141]

I own a denon avr 1803 with a standard subwoofer ouput, not one markd LFE. My question is: Is there a big difference/benefit to using an LFE output vs. the standard sub output?

[shack]

They are the same.

One in the same - my man. Some say tooomato some - say taaamato.

Ronaldo141 I am using a Denon 1603.Denon does not mark LFE on the Amps LFE outlet, just sub out. You may have LFE marked on your subs input.

Set all your speakers to small.
Set your Cr.Over to 80 Hz.
Set your SW Vol to -3db.
Run one RCA cable from the sub out on the Denon to the LFE (unfiltered) port on the Polk sub.
Adjust bass volume on the sub using the Test Tone button on your remote.

With the "Low level LFE connection method!" you will not be missing any bass tones or double filtering. You will reap the benefits of better mids and highs. You will have a cooler running Amp and less speaker wire running all over the place.

thanks for the help guys. Right now I don't think it would have made a lot of difference as I am using a 50 watt sony 8 inch sub. :( .I was looking at the velo cht-8 this weekend at CC though.....nice sub. A bit pricey though. May go with polk psw 303 if i can find it cheap.

Buy Gonzo's CHT-12 for the screamin' low sum of $250!!!!!!:cool:

A great sub for a great deal.

[ronaldo141]

sounds like a great deal dr. spec, but i'd have to convince my dad as well and seeing as he's not as much of a bass man as I am, it'd be hard to justify the purchase. Oh well. Maybe someday......Besides, since school started haven't had that much time to listen to music/movies anyway. But come summer......sub options will have to be reevaluated :) I'll let you know when anything changes.
P.S. Dr. spec, would u mind telling me differences/benefits to ported and sealed designs of subwoofers and speakers in general.thanks

Phew - ya got all day?

In a nutshell, a sealed sub generally has less sheer output and a slightly tighter bass response. The sealed enclosure "loads" the woofe cone and provides slightly better better transient and decay characteristics. It does not extend as nearly as deep unless an absolutely huge enclosure is specified.

The ported enclosure has much better output, much deeper extension in the same size enclosure, but might give away a bit of tightness compared to the sealed unit.

In practice, a properly ported sub can sound every bit as tight as a sealed sub - it's just harder to hit all the design parameters just right.
