Dirtrun,

You seem very knowledgable in SVS. I have one question, how well do they do music? I am heard Velo and Paradigm for music since I also listen to a lot of music (ranges from classical to rock) and on most occasions I do not enjoy the integration of the sub for music. I use the Dali Ikon6 series and and the Dali Ikon sub. So far, it is not earth shattering for HT but it is a nice compromise for music as my mains do not go below 37Hz and the subs allow for a range up till 25Hz. Also classical music sounds much nicer with them.

Any comments. Else I would need to have 2 subs in the main room and then would need to add a SVS AS-EQ1 to separate the HT with the music.

Can..can.will update when back in Pg.

Thanks Dirtrun

The Dali is a compromise but it is not a sealed sub as well. I use a dedicated integrated amp to drive my fronts anyway. Have to decide soon.

Hei, I say can can to checking Ronnt's setup with SPL Meter lah, not to the SVS. I have not decided on the SVS yet!

75-80 dB using slow "C" weigthing

Actually, I am hoping that Malaysians would finally be able to enjoy SVS via a local distributor....hint hint...htkaki

Hope you come up with irresistable prices...

lightning69,

My advise to you would be to use this software called REW and run you sub and your mains together. This will help to identify if there is a problem. Pls pm me if you need help. Another thing to note is what is the settings on the AVR. Was Audyssey run? Maybe the internal trims are set too low.

You need a laptop/desktop, a soundcard with line out and line in (not mic in) and some cables. Do a google search on REW. It is pretty easy to use, what you will get is a set of graphs showing your room response to a frequency sweep. You can move your sub around and see what is the most neutral integration with your fronts.

It is a powerful tool, either that or use the test tones and move the sub around and measure with the SPL meter in your primary seating position.

No, these are room problems.

I wish we could check it with Audyssey. Audyssey has 8 times more resolution in the low frequencies just to improve these points. While it cannot fix the drop, it will balance it out.

I would suggest this, put the subwoofer in ur primary position and play the 40Hz, move around the room with the SPL meter to see if you can improve it. Then re do this. As pierreye suggested this is the easiest way.

Current Audyssey MultiEQ XT will help in reducing the effect of the peaks and valleys. See my graphs in the subwoofer section. It is still there but flattened. Room treatments are the best way though.

An example of a graph with and without Audyssey.

The 1st one is without Audyssey



The 2nd one, no change in anything except engaging Audyssey.



The graph without Audyssey has a sharp peak at abt 32Hz. There are also 2 dips at 50Hz and 70Hz.

With Audyssey, the peak at 32Hz is smoothened. The dips at 50, 70Hz are now less pronounced.

The 200Hz dip is seen without Audyssey and it is quite big. Whereas with Audyssey it is better.

One simple way of doing it is using REW. But u need some cables, splitters and a soundcard that has line in and line out.

ar188,

This is a concept that a lot of people fail to understand. The administrative portion is totally not factored into calculations as well. Time is money and it is not free.

All,

This is the 1st step into gettting some previously difficuly to get brands into Malaysia. Pass all your inputs to htkaki and always keep in mind that he is not doing this for charity. He has stated a couple of times that based on the support that he has seen, he has been thinking of setting up a store somewhere.

Some of the points that mys_terious puts out helps htkaki iron out the kinks in setting up a new business and it helps all of us. Give constructive feedback to any logistics and after sales issues that will help us all.

The after sales service is another factor that needs to be considered. As his volume grows, I am sure he will do his best to reduce costs and pass on the benefits to us.

I am hoping that he also obtaines the dealership for obscure brands that are great but not available in Malaysia.

PB13 might be too big to go under ur cabinet bro....

robin,

Its supposed to have more resolution in the low frequency end to deliver a flatter SPL curve vs frequency.

There is a reason to add a sub EQ. The lower frequencies are the most difficult to tame. Also they are most apparent in a system. A peak in the wrong area might make you feel like u've got great bass, but in essence what it is doing is drowning out the other frequencies.

Sigh, I see ur siggy and regret not being able to come to watch this event!

lightning69,

Jchong put it correctly. It is up to the individual. I believe you do not even need to invest in the sub eq. 1st would be to chart your current performance. Then, with no cost associated and if your room would allow it, move the sub to various positions and see the response. I don't believe you need to be aiming for perfection but instead without spending any money, just the best that you can get. I believe in recreating what the director intended and do not want my room to distort any more than it shd.

Try charting your room response and then decide. In your case, since u hv invested in a 1st class sub, why not optimize the position based on actual data instead of only the ear. With the data and your ear, you can make an informed decision. If a flatter graph does not sound correct to you, then u made the choice based on data and not just the ear. The ear can fool u.

For all u may know, ur sub might already be as flat as a prairie......

Anyway, my 2cents worth....its ur sub, ur room and ur wish in the end.

Also for certain frequencies the drop even at 700ms is low. These frequencies tend to stay in the room and muddle up the sound of other frequencies.

taqies, I was under the impression that Audyssey corrected in the time domain. Not sure if these readings are post Audyssey.

The best would be a quick drop and if possible drop by more than significant amount within 300ms, this way they disappear fast enuf before the next scene comes up and not muddling up anything else. Low frequencies will stay in the room longer, there is nothing u can do abt that, all u can hope for is that it drops fast enuf not to mess up other frequencies.

REW is a very good tool to examine and understand your problems. Subs can be made better or worse by moving even by 1ft, they are critical to get right. If u cannot, a tool like Audyssey can do it well.

I see a lot of comments that says the results after Audyssey were not good, did not sound right. I'll tell u why, without room correction, you were probably "feeling, hearing" bass that was not meant to be heard, reverberations caused by slow decay, and some "peaks" that made u feel the oomph. Room corrections tries to fix this and its not all bad.

However, its ur equipment, if u r not interested in accuracy, then by all means do what is best for u!
