Instead of just sharing my problem and solution I used, perhaps some sifu can share and perhaps point out some advice if I could do better.

This is my setup:
1. Front : Wharfedale Diamond 9.1
2. Center :Wharfedale Diamond 9.cn
3. Surround : Wharfedale DFS-18
4. Sub : Wharfedale WH-210.
5. AVR : Yamaha RX-V465

Is a budget setup yes, so not many areas that I could tweak and tune.

After about 1 month plus, I guess the speaker has good run in. So I refer back to the expert test of the front speakers and notice this that the hump on the front speakers was not at 100hz, but at 300hz. See chart below:



Notice that 300hz bump? Well, is the nature of the speaker.

So I downloaded a trial tone generator and play it thru my pc via front Aux input. I dont have any SPL meter or spectrum analyzer so what I got is my pair of ears.

after sweeping the tone from 50hz to around 500hz and play around that range in more smaller gap, i finally ended up with these settings for bass management:

1. Crossover at 200hz at AVR.
This sound odd right. I agree as well. But this help to tone done those hump as shown at the chart above. When cross at 100hz, the volume of anything above that can really be heard clearly loader until it reach around 400hz. Thats how bad is it. It somehow colored my bass especially when I listen to Norah Jones. Some may like that louder boom but for me, as musician, I love natural bass sound and that need not to be boomy.

2. Cross at the sub 170hz.
The max my sub could do. This may sound like there is a gap between 200hz and 170hz right?. Well, by looking at these setting, it does shows a gap but when I swipe using a tone generator in these range, there is no sign of missing freq. As matter a fact, it sound better than before as it help to tame the freq around 150-200hz range.

3. Change the phase of my sub back to normal. This help to tonedown the room effect at 90hz as I suspected earlier. This need to be experiment many times playing and changing the phase. Small room 16ft x 16ft type will give this impact naturally. :S

4. At my AVR, I cut the front L/R and Center at 400hz. The best and nearest to 300hz. ( default 63hz, 160hz,400hz). so this help to tone down further the upper part of the 300hz as seen in the speaker freq respond chart above.

So hows the result. Somehow, the Yamaha EQ when I do YPAO is bright. Norah Jones piano is not distorted when I played loud. The bass now feel natural but still not as smooth but at least better than before when it was too boomy.

Movies not a problem too. Play all the power bang and boom as need and still shaking my apartment.

I no the setting sound strange, but it is something that due to speaker, AVR and Room capability.

Share your setting and for those with Wharfedale Diamond, hope to hear what you done to your bass management too.

TQ. & Happy Tuning.

I think you could use some bass traps, if the aesthetics can be surmounted

Actually, thats a good idea to improve room acoustic. Until I cant tweak anything, that would be my choice. This is my living room. So Want it to be as tidy as possible.

Since you do not have any equipment, whatever sounds good to ur ears is what matters.

However, a point to note, what you see in the chart is the anechoic response, ie, not taking into consideration the room. In ur case, it might be different after room interaction.

You are right. I met an expert today where he said that my room could make it worse. I suspect also. Standing waves is like everywhere. Well.... No choice, have to satisfied what I have as a living room. Got to balance also.. ha ha. Or else, it will look like my recording room. Sponge everywhere.

sounds like a job for the AS-EQ1 ?

costs more than the audio system?
