A&L quote RM1800 for 10R and RM2400 for 12R.

No leh, went to the AV show yesterday. They quote me this price.

Go for the SW150. Much better than WH210. Around RM1300.

I think this model is slightly cheaper than SW150 according to this website

http://www.e-cms.biz/products.asp?categoryx=29

SW150 is around RM1.3k.

Somehow I find the downfiring sub more umph

Me. SW150. Lonely guy.....

Wah, got elite Megatron to keep me company......

I think the LPF (Low pass filter) should be set to the max possible (120 hz if i'm correct). If you set it to 80 Hz, all the frequency between 80 - 120 hz from the LFE channel will be filter off. The 80 hz recommendation from THX is for the other 5 channels not for the LFE channel which mean any frequency below 80 hz from the 5 channels will be send to the subwoofer plus the original LFE channel. The LPF setting is meant for those people who had subwoofer humming problem which they can minimize by reducing the LPF frequency. If you don't have this problem, set it to the max possible.

I think he is talking about the LPF setting in the amp, not the setting at the back of the sub.

Swine, can u confirm?

Set the LPF to the highest possible for the LFE channel (note LFE channel only, not the other 5 F/C/S channel). On the sub, set it to the highest possible, let the amp control this. If you face some distortion, try to reduce the dB level for the subwoofer. Did you calibrate your sub with SPL meter or you just use Audyssey?

Yes, set the LPF to 120 hz on the AVR and the sub. LFE channel usually coded at 120 Hz and below. This mean all the LFE signal will be channel to the sub. If you set at 80 Hz, that mean from 80 to 120 Hz signal from the LFE will be filter away. Now don't confuse this with the 80 Hz setting for the other 5 channel (Front/Center/Surround). You can use THX recommended setting of 80 Hz. You can tone down the subwoofer by reducing the setting by a few dB if it's too bassy. Another way is to move the sub away from the wall.

If you set the LPF to 80 hz on the sub, any frequency above 80 hz will be gone including those from LFE channel. The setting at the back of the sub will not tell the AVR to direct the frequency between 80 - 120 to the front. The lpf filter on the back of the sub will be the last filter that the sound signal will pass thru. So you should set it to the max possible. If you can by pass it, better still. Let your AVR control your frequency setting. Not sure if you get what I meant here. Let me recap : there are 3 setting here. The first 2 settings are in the AVR which is the LPF for the LFE channel and the freq cutoff for the front/center/surround channel. Then there is another manual setting for the LPF on the back of the sub. The correct setting if you want to follow THX recommendation should be :

LPF for LFE Channel : Set to 120 Hz
Freq cutoff for Front/Center/Surround : Set to 80 Hz
LPF setting at the back of the sub : Set to max possible (120 Hz)

If u follow this setting, the full freq range from the LFE channel will be send to the sub together with the signal from F/C/S which is below 80Hz. When this signal reach the sub, it will be able to pass thru all. If u set at the back of the sub to 80 Hz, those signal between 80 -120 Hz from the LFE channel will be filter away. Hope this is clear enough.

Wah, so many questions.....Anyway I'm not sifu...Just share what I read...Here is another link you can read up :

Actually we cannot follow THX recommendation blindly. You have to see your actual speaker capability. Look at the frequency respond capability (usually stated in xx Hz to yy kHz with +/- 3dB). If the minimum frequency is higher than 80 Hz, then u should not follow because you are now straining your speaker below the frequency response it capable to produce effectively. Usually Front speaker wil able to use 80 Hz but surround could be a problem if you use those small bookshelf. Eg my Mission MH3 Surround only capable of producing 110 Hz. So I have to set my surround channel cross over at 120 Hz but my Front (M33i) can produce down to 44 Hz. So I can use 80Hz per THX.

Really? Yammy 1800 is higher range than my 606. Are u sure we are talking about the same thing? I'm refering to the cross over frequency for the front/center/surround channel, not the LPF setting for the LFE channel.

No, because between 80 to 120 Hz will only have 1 signal from your LFE Channel. Your cross over for the 5 channels are set at 80 Hz so only signal that is below 80 Hz will be send to your sub.

Please let us know what is your frequency response on your front/center/surround speaker. I think your surround had limited range. That's why when u set it higher from 60 to 80, your surround now more open up. Don't worry too much on your sub as it has it's own amp build in and only need to drive 1 channel. Your AVR has to drive 5 channels. Relief some load from your AVR to your sub will help.

Your user manual should have this info. If not then use Audysey to setup.

Another option for you :

1.AMP: Yamaha 663 = RM1900
2.Speaker : Mission M33i = RM1200, Mission MH3 Center + Surround = RM950
3.Subwoofer: Wharf SW150 = RM1100

I bought my 606 from Singapore for RM1700. In Malaysis, it cost around RM2k+. You also from Penang? Can arrange the time but got to be 2 weeks from now as I will be travelling soon.
