Gambit - you say that you've set your crossover to 100Hz.
That may be too high...
Anything approaching 100Hz equates to the bottom end of the sound spectrum becoming directional...
After all, you 'shouldn't' be able to hear where the subwoofer is positioned in your room.

Try running it at 80Hz if you're watching a movie, 50 - 55Hz if you're after a sound better suited to music reproduction. Of course, these things are solely down to personal preference, so really it's a case of experimentation.

Thanks dunnersfella.
Will do in regards to the sub.
I just don't think my amp is powerful enough to run the wharfies so i'll just have to put up with it.
Does sound fine but just no LF from the fronts,no majors.
Thanks for everyones help.
The search for a new amp begins!!!!!

Right, this may already have been covered, but please try it all again without the subwoofer connected. Set the receiver to subwoofer = NO.

If this works and you suddenly get good bass from the front speakers then I would suggest connecting it a bit differently just whilst you have this receiver. Namely, forget the subwoofer setting from the receiver as it appears to cut off too high, creating a hole between the front speakers and what the subwoofer can come up to.

Plan B could therefore be to connect your subwoofer via the front speaker cables. Assuming the subwoofer has speaker level connections. This would send all the bass to the front speakers and you'd actually send this off to the subwoofer first and then back to the front speakers. = Lots of cables but might sound better.

Really though, please try without the subwoofer connected to see if it is the subwoofer crossover that is preventing bass signals going to your front speakers.

Also, as mentioned above, even though you have set the front speakers to large, you may still need to find another setting that sends the bass to both the subwoofer and the front speakers. On a Pioneer receiver I had this was called 'double bass' or something.

This is the back of the sub.
Do you mean connect the front speakers to the wire connections?
I assume the speakers will be connected to the reciever then onto the sub.
I have tried subwoofer off and the fronts still sound the same.
I will try wiring the fronts onto the sub and see what happens.

Thanks

Yeah, there are speaker level connectors on the back, for use when you recevier doesn't have a dedicated subwoofer line level output. Yours does, but if it's not so great then the speaker cable connectors is a back up plan for you.

Gambit:

No I'm meaning, please remove the subwoofer altogether and set it to off/no in the receiver.

When it's gone the receiver shouldn't use the cutoff and it should send everything to the front speakers when they are set to large. The point of testing this is to see if the subwoofer cut off is causing your problems but cutting off at too high a frequency, so no bass at all is going to the front speakers.

Ok thanks.
In that case you won't gain anything, in fact you'll lose it.
If bass is not going to the front speakers then using that as the feed to the sub won't help.

Are you sure the connecting terminal plates are in place at the back of the front speakers?

Might pay to get some real bass content on CD or something and test it out now.
http://homerecording.about.com/od/homestudiobasics/a/test_tones.htm for example.

One last thing I can think of is that your receiver is applying some form of EQ that isn't particularly great bass wise. What is showing on the screen when you play a bluray/cd etc, and how have you got the source connected and set up? Like is there any setup on the bluray player etc that's actually impacting on what is sent to the front speakers?

Failing all that, get a new receiver, or at least try the speakers on another type of amp to make sure they are working ok.

HI Jaxson,

Thanks for all your help.I will have a look at connecting the speakers to something else to see how they go.There is no bass from the fronts through ipod,blu ray,dvd,stereo,tv or xbox.
That about covers it.

Please upload a photo of how you have connected the speaker wire to the speaker terminals.

Hi jaxson,

Just got home and hooked them up to a old midi system i had floating around.
Just using the fronts and they sound REALLY good!
Nice bass and very tight sound.
Do you still want a photo?
I reckon it's the amp personally - old piece of .....

Thanks.

So with the receiver set to: Front = Large, Sub = No, Center = No, Surround = No, how do the 2 floor standers sound when in 2CH ST mode? What are the Bass and Treble tone controls set to?

Hey Grolschie,

Still sounds pretty much the same.Also had it at 70 out of 74 volume on the amp.No good.
Sounds far better on the midi system,an old philips with no sub or anything,just left and right.
Amp=Fail.

Oh well.

It all sounds weird and No I don't want a photo now.

I'm sure a setting in the amp is off/wrong. It plain and simple shouldn't sound like you are reporting it.

Jumper bars must be correct if it works on another system.

Sure you haven't hooked the fronts up as surround/back channels or something?

As above, with those settings: Front = Large, Sub = No, Center = No, Surround = No, it should send the bass sounds out through the front two speakers.

I would try the Eq settings so there's no signal processing being applied etc as well initially, but yeah, if you can't get it to work then get a new amp.

Oh. Possibly not good for the speakers. Clipping is bad. I imagine as the volume control goes up, the lower frequencies attenuate possibly due to the power transformer not being up to the task. 86db sensitivity 6 ohm speakers would need a reasonably grunty receiver I suspect. I could be wrong.
