Anyone want to pinjam my SPL meter, PM me. But you have to come and get it from me lah, no special delivery. If someone already pinjam, must take your turn.

Also can pinjam my DVE: HD Basics audio-video calibration disc. From this disc can also learn so much about movie digital transfer/scan, home theater, HD audio & video process, TV technologies, and many more. But after borrowing this disc, make sure you learned thoroughly, must have answer perfect score to a special test.

Don't be mad if I don't reply PM promptly, because I rarely online nowadays.

Not surprising, subwoofer only handle low frequencies, at least 80Hz and below. If you can detect the location of the subwoofer just by using your ears, then the crossover was set too high. The subwoofer is suppose to make you "feel" the bass, not hear it. When set and calibrated properly, the bass will blend seamlessly with other channels.

Well, McD seems to get stuffs from Pioneer now. At McD Kepong, they hang a 50" Pioneer Kuro LX508G. I literally shake my head in disbelief, they could just get a cheap 32" LCD, it seems really out of place, the outlet was very small even though got upstairs dining area (the TV is downstairs).

By the way, those who want to borrow the SPL meter, PM me lah..

Depends on ears, but according to THX, anything above 80Hz will be directional, meaning you'll be able to locate the subwoofer's location just by hearing, which is not the way it should be. But some people don't mind this or still can't detect the location at up to 120Hz, so it's up to individual. Some also claim higher frequencies will produce more thumps and sharper bass, especially drum/pedal heavy for music (for music, it's more about setting the discrete channels crossover, not LPF).

The LPF (Low Pass Filter) is only for the LFE track in the .1 channel of movies. Meaning the sound engineer of the movie itself has already set the proper crossover to the movie's 5 channel track for you. But some of them like to put the LFE higher than 80Hz, so that's the purpose of the setting in the AV receiver, to cut-off anything above whatever you set from going to the subwoofer. Again, it's up to you. For me, I want to hear exactly what the movie director/sound engineer intended for us to hear (just make sure the subwoofer can handle frequencies as high as 120Hz).

If you've set the bass management in the AV receiver, the setting on the subwoofer should always be set at maximum/bypass/direct.

The more important is the individual channel low frequency crossover, this will effect both movies and music. It's still important regardless of the movie director's intention, because low frequencies that the speaker can't handle will hurt the speakers in the long run.

Added on February 3, 2009, 1:46 pmSeems that your receiver can't do bass management for speakers and LFE separately. In order not to get the correct setup, the best is to set at 120Hz, and set the setting on the subwoofer to 80Hz to filter anything above that. But this will make you not hear anything from 80-120Hz of the LFE (if there is any, though I tend to believe the LFE track won't have anything much above 80Hz).

Another way to get all the frequencies (this is used more in a hi-fi setup) is to set in the receiver without a subwoofer (5.0 setup), so the receiver will channel the LFE track into the front 2 channels. Connect the speaker out from receiver to the subwoofer's speaker line-in, and then from there line-out to the front speakers. If the LPF setting on the subwoofer is set at 80Hz, then anything above that will be channeled to the speakers. Quite confusing I know, and I also don't recommend this method.

NOTE: All LFE track on a THX-certified DVD/BD will only have 80Hz and below.

No one is saying the 80Hz is a must, that's why we say it as recommendation, not a rule. You can even turn off crossover if you have full band speakers. That's the main point of this whole LF crossover, to let the subwoofer handle the low frequencies that the speakers can't handle, everybody knew that already.

Can't trust auto-calibration 100%. Can use it as a guide, but I recommend everyone to use an SPL meter to counter-check everything afterwards.

Mega, yup, my previous Yamaha 1800 can't do crossovers for all speakers individually, only one setting for all speakers. If my front's can go down to 40Hz, center 80Hz, but surrounds 100Hz, I can only set 100-110Hz for all of them. That's one of the main reasons I sold it.

Wah, YCS so rajin.

I hope the SPL meter is performing well.

I'm not a Sifu, much more to learn, but will always glad to help. Even the higher end Yamaha like 1800 can't do indvidual crossover, so I'm guessing it would be the same with you model. Don't have first-hand experience though, maybe Htkaki can help.

Htkaki, is the newer 1900 still the same? I know the YPAO in 1900 is upgraded to have multiple point auto-calibration, which the old 1800 only one.

By the way, can call me Master Oogway.

Well, Onkyo 605 can do individual crossover too. That's lowest end of Onkyo's HD receiver line up.

Makes me wonder, why Yamaha still holding back?

Full range speakers no issue, can put as LARGE anytime, no crossover needed. I still set at 80Hz for my fronts, main reason for movies. But when I listen to stereo music, I always use Pure Audio (Pure Direct in Yamaha) which will turn off all processing including crossover, so it's the same as setting it as setting the speakers to Full Band (or LARGE in Yamaha).


Agreed.

Slicardo, I had the same issue when I first got my 10R too. But after manually calibrating and tweaking the EQ, it is now working very amazingly, I really have no intention to upgrade the subwoofer anymore.

Owners, please add your name or correct the list accordingly.

Wow, everybody's upgrading!

Just make sure with all those big boxes and bolsters, they won't overpower your system overall. Those with small receivers (like Yamaha RX-V663, only 90W per channel) will certainly be buried deep in by the LFE of the 1000W subwoofer. No rules of course, the bigger the better, but just make sure it's properly calibrated, tuned and in-phase to your whole system.

Anyway, I've swapped emails with SVS before, they're very friendly and will answer to all your queries. Yes, door-to-door delivery will take care all of the tax/fees, you'll only pay to the delivery guy when it arrives to your doorstep. Good luck everyone.

Very true. Me just finished my Round 1. But you guys are on Round 3 already.
