Should free to me ma

80w ma 很低 tak boleh

Got some question for sifu on sub, LFE and crossover. I'm using a Yamaha AVR in 5.1 with tower for LR.

1. If listening to stereo source in stereo mode, will the sub be used?
a) since the LFE channel is not active, I assume it won't be used.
b) I remember reading somewhere that setting the LR to small will enable the sub, is that true?
c) will the crossover affect the LR channel, i.e. sound be removed?

2. If listening to stereo source in music mode, i.e 5 speakers, how is the sub used?
a) since there is no LFE in the source, bass below the crossover will redirect (remove) from LR to sub or copied from LR to sub?

3. Watching 5.1 movies, is the sub strictly for LFE channels only or also comes from crossover?
a) Again how would having set to small speaker and large speaker have any effect? Logically it should remove sound from crossover point and send it to the sub if the speakers is setup as small.

4. Assuming there is no sub, would the crossover setting still relevant?

Sometimes I would not turn on the sub and wonder how all these setting would affect the LR speakers. If I don't turn the sub on, do I need to also set the AVR sub to none (5.0) as well?

Thanks.

Is the amp 80watt, but when I watch movie powerful .

set crossover nia.
500w will explode the room

Maybe you can request them to give you FOC since getting a pair of expensive speaker from them.

Actually thinking of FOC for the speaker wire as well

Haha... During promo some dealers may give out free gifts... maybe during AV show got chance!

free gift give out with no condition?

So it also 500 watt, same as B&W

But which one better?

Maybe like buy projector free projector screen or buy speaker free brass spike...

You still need interconnect

what i mean is powerful sound can be tune by speaker crossover high. not saying nht is 500w
this will shift the focus toward midbass instead of deep bass.

Thanks for ur explain.. Till now I was searching how many watt is this speaker. Very hard for me to choose it

thats why recommend u take branded like bower wilkin as700. got specs detail and resale value if not suitable

Ok , noted , NHT also branded in USA

Is elac sub as good as svs.tq

No

1) If you set your receiver in "Pure Direct", the sub won't be used unless you manually set the crossover on the sub itself because on Yamaha's receivers, engaging pure direct will disable the bass management from the AVR itself.
You seem to be mistaken that a crossover point would mean it removes something from your speakers. The meaning of a crossover is basically what it says, a crossover = a bridge in layman terms. All a crossover does is moving the pre-determined frequency set by the user to the sub. If you set it to 80hz, then ANYTHING below that goes to the sub, plain and simple. Of course, if your sub cannot go down to the LFE frequencies (20hz and below), then it will simply distort or have inaudible volume down in those areas.


2) If you bass managed properly in the first place from the AVR, using any "music" DSP or upmixer (PLII, DTS Neo), anything below the crossover point will be sent to the sub. As explained in point no.1, anything below the set xover point will be sent to the sub. It is NOT copied nor is it removed from the L/R channels, it is just being re-directed to the sub.


3) As already explained, ANYTHING that is set below the xover point is sent to the sub. If the movie has 20hz content and your sub is capable of playing down that low, then yes with a crossover above that; the sub will indeed play it. You set the speaker SMALL BECAUSE you are limiting its bass output and sending it all to the sub.
There are really only a few tower speakers in this world that can play CLEANLY down to 20hz, with no distortion. SMALL and LARGE has very little to do with the physical size of the speakers.


4) No, if there is no sub then you set your L/R speakers to large and everything else to small. If your center channel is gutsy enough, you can set it to large also. What does this does is the AVR will redirect the bass to the speakers designated as large. Whether it plays the bass frequencies down to its "rated specs" with authority or not is a different matter.


If you don't turn on the sub, then simply set the L/R speakers to large from the speaker setup menu. You can also set different "SCENES" for your AVR. So you can have SCENE1 with settings for the sub enabled (with bass management) and you can set SCENE2 with no sub, no bass management. There are a lot of things you can do with your receiver, you just need to read the manual and figure out what does what.


Which ELAC sub and which SVS sub? While not a single ELAC sub will match any from SVS, the ELACs are considerably cheaper while not being rubbish like the majority of mainstream cheapo subs (you know like the ones from Polk, Pioneer, Dayton and so on).
