Better bass response between sub and receiver???

[mtbound10]

I have a Yamaha RX-V 863 and a EMP 10 sub. I am trying to get them to work better together so that the sub is more responsive. I am using small EMP ECA 4 speakers front and rear which do not carry any low frequencies so I am relying on this sub to do 95% of the work. It has good placement now all I need is to get the crossover set up properly and figure out what controls what....

What do you guys think? I am tired of watching the money shot and then all of a sudden hearing the sub kick in at the very end... very depressing

signed,

wanna hear the bass go boom more often

Hi. Sounds like your sub's auto-on sensor isn't getting a strong enough signal to keep it active. I don't see a constant on setting for the sub, so let's try the following. Turn the subwoofer level on the receiver up higher, and turn the volume control on the subwoofer itself down to compensate. What that will do is send a stronger signal from the receiver to the sub that might keep the subwoofer powered on.

If that doesn't work, please just let us know.

I suspect everything is oversold and hyped on this rig. I don't believe the manufacturers claims or the alcoholics review for a moment.

Next you have a misconception, you never can, or should, have a sub do "95% of the work."

The satellites have an F3 of 100 Hz, as far as I can tell this is a sealed unit with a 4" bass mid. So this unit will roll off 12 db per octave below 100 Hz.

The woofer as far as I can tell is a 10" sealed unit. Frequency response is reported as down to 30 Hz. However it is not stated how many db down it is at 30 Hz. For a driver of that price I can be certain it is at least 12 db down by 30 Hz.

So the whole set up is not promising.

Now I suspect for power reasons the satellites are not diffraction compensated to any significant degree. Most of what is perceived as bass is from 80 to 150 Hz.

That being the case, I would set the crossover to the satellites at 100 HZ.

I would place the sub close to one speaker and set the crossover as high as possible which is 150 Hz.

Try that and tinker from there. If you still have the problem with those settings, there is no solution except to get rid of that speaker system.

With that rig there is no way you will get impressive deep bass.

When you mention the "satelites" crossover... do you mean the crossover on the receiver? I already have my crossover pegged on the sub to as high as it will go.

If the problem is that the sub kicks in late, then it isn't a matter of crossovers. (TLS Guy seemed to interpret your post as a general dissatisfaction w/your sub, which isn't what I get from it).

Have you tried Adam's sugggestion?

Yes set the speakers to small. The crossover to the smaller speakers at 100 Hz. Sub yes, set the sub crossover on your receiver to 150 Hz if you can. I don't know if you can do this on your receiver. The crossover on your sub is inoperative on the LFE input according to the manual. If you can't set the crossover to the sub independently of the others, then set all to 150 Hz.

I could not find any measurements of your speakers on the web, but did some towers with the same drivers. They were rolling off at 150 Hz. The frequency response graphs were really dreadful. I did spend sometime in the EMP room at SOTU. I felt the sonic standards in that room to be far below acceptable and noted such in my review. So you may be expecting too much from this system.

I had not considered that your sub was not making any sound most of the time. If that is the case turn your sub level up on the receiver and set levels with the sub volume control. So it is possible you do not have enough signal to drive the auto on circuit. However there is no mention in the manual that this sub has an auto on.

The EMP site has little useful information about your speaker system, but I have found from other sources that the sub is ported at the bottom, so it could have an F3 close to 30 Hz. However I came across reports that this sub is a long way off being very potent, and seems to favor small rooms.

Here is what happens... most of the time when I am listening to whatever... all of a sudden the sub will kick in and the speakers sound full all of a sudden with bass present.

There is an auto on/off feature built in to the sub supposedly. It stays on 24/7. I remember asking one of the engineers at EMP about this cause I was concerned about overheating.

Right now my subs internal crossover is set to 150 or as high as it will go. My reciever is set to 100 I think is where I left it yestereday. Volume is about halfway on the sub.

Let me just dispel any myths... I am not at all unhappy with this system. When watching movies, especially blu-rays this sub has done phenomomal work... I know it works! But it is getting it to work repeatedly that is the issue. I might have to go back and try the YPAO again and see if that does the trick and adjust from there

P.S. TLS Guy~ I don't know what you do for work but I hope it has something to do with music to have a set up that would make most top producers and recording artists jealous of!!!! Cheers to your system and thanks for the feedback...
