Axiom Home Page Forums General Discussion Home Theater EP500 bass output

Hey, I was able to get a new receiver and new subwoofer cable to test my EP500 sub.

Now I am just wondering about the sub output.

Now dont get me wrong, the EP500 DOES give A LOT of bass. But for some reason I think I am overestimating my expections.

Why I think so? Because a lot of members in this forum report that they only need to turn the volume of the sub only 1/3 of the way and its give A LOT of bass.

But for me, I need to turn it half way to get a good optimal amount of bass.

I put the sub in the corner of my room and I configured the settings (db and crossover, etc) with the A/V receiver.

I think it may have to do with how large my basement is. It is around 6500 sq. feet and it opens up to upstairs. It can also be by what track or movie I play.

Tonight I am going to test out Minority Report.

Paul,

If you're only half way and that's not satisfying your thirst for BOOM BOOM, turn it up .

Also remember that music does not usually have deep lows. I don't remember how good the LFE is in Minority Report but in U-571, the depth charge scene shakes my couch with the 600 in my 4,000 cubic foot space with plenty of headroom on my receiver and sub volume to go.

Also make sure that you have the 500 set on by-pass and flat (since you have such a large room).

6500 Sq ft?????????????

of cubic feet?

there is a huge difference.

My room is 8,000 Cubic Ft+ and my 500, or currently 600 is plenty. Most people run their subs way to hot and don't understand what the sub's purpose is for blending properly with their mains, just my opinion.

Cubic.

I just watched Minority Report, and I was very impressed with the subwoofer output. I had it at 10:30 o'clock position and I found it suitable for the space that I had. There were some rattling because of loose objects [such as one of my light bulbs in the ceiling (prob. loose)]. But other than that it was fine.

Just wondering, at that volume position is it normal to turn it up that high for the amount of space I have?

BTW, I have set the crossover to the mains and sub to 40 Hz (M80's), so I thought both of the components blended well together. Yes, I do agree that having too much bass/boom effect doesn't sound too well. But in my case, it's not like that. Could it be the layout of my room? Some architectural design of my basement?

Oh, and it's cubic feet, not square.

Oh btw Randy, at what position do you have your EP600 volume level at and how much cubic feet do you have in that room?

Paul,

Keep in mind that the EP 500's power amp output is related to the pre-amp's input voltage signal...can't really compare HT sub settings as different pre (receivers\stand alones) linearities will be different!

My EP500 volume setting changed from 7 o'clock (Sony Receiver) to 8 o'clock (Emotiva pre\pro) to maintain flat output in my surround system. At the 10:30 o'clock position, your receiver's LFE pre signal probably is somewhat less than most, but you should still be driving the 500 power amp the same with plenty of dynamic headroom!!!

Don't fret, the Axiom DSP in the amp's signal path should provide you with bullet proof performance...Enjoy!

Paul, as I mentioned above, my recroom/HT room is 8,000 cu ft +. I was just confused when you said Sq Ft in your original post.

My Volume(gain) on my sub is around 7 o'clock and about -6dB on the receiver to achieve 75dB SPL on my Radio Shack meter.

Keep in mind, our getting the full power of the subs amp no matter what your gain is set. The goal is to calibrate your sub's levels to match the other speakers in SPL.

What Theo said above is correct. However, it doesn't hurt to give you other people's settings for reference.

My 600 is set at 9 o'clock with the receiver set to -9dB to achieve 83dB using the noise generator in my Denon. I have 4,000 cubic feet.
