How to Set Up a Home Theater System : Choosing a Sub Woofer for a Home Theater


Hello, I’m Reggie Hayes here with Expert Village,
and we’re talking about the subwoofer. What is a subwoofer? The subwoofer is just an oversized
speaker. Again this one is like a 12-inch speaker right here. It, it is your base. It
is your explosions. It’s your booms. It’s your rattles. It’s everything. It shakes the
couches. It shakes the walls, and it shakes the neighbors sometimes. But, they’re very
cool to have. Now this one is a much more powerful speaker than the one that we have
for our little 12-foot room here, but it is designed for much larger rooms. Now the purpose
of the subwoofer is to protect the main speakers. Your main speakers, especially the smaller
main speakers you have, they really cannot handle these really low tones, and that’s
why you have these. Now, what’s so intimidating about ’em sometimes is this right here- the
hookups. Now, this one right here has a lot of features. It has more features on it than
are really necessary for a subwoofer. And what I mean is that it can separate your speakers
right here. It takes speakers out, excuse me, it takes input from your speakers and
can output your main speakers. You really won’t need that. The main thing you really
need to worry about is your main inputs right here. Those come from your receiver. Now,
right here is your volume. Pretty much all your subwoofers are gonna have a volume, and
you can play with that and find out how loud of the bass tones you want. Phase. Now phase
is something really interesting. As we said earlier in the main audio, speakers push air.
But it’s very important that when speakers push air at the same time and at the same
rate. Your speakers are pushing in like that. Now if all of your speakers are pointed the
same way from the front of your entertainment center, they’re going to be in sync, or what
they call in the phase. They push and pull at the same time. The subwoofer usually sets
across from the other side of the room somewhere, like in our case, near the couch. However,
usually you’ll turn it around which means that it’s working against your other speakers.
When you do that this one is nice enough to have the phase feature. You just flip the
switch to 180, if you spin it around like we had it earlier. It’s really technical.
It’s probably way more technical than I need to go into with you guys, but you guys should,
it?s just there for you guys to know in case you want to explore. The best thing to do
is to play with it and see what sounds best for you. The crossover frequency is the last
part of the subwoofer. It’s very important. It is the point at which, it sends, it stops
sending low tones to your main speakers and starts retaining them in the subwoofer itself.
The larger the speaker, the larger the main speaker, the more base they’ll be able to
handle. However the smaller the main speaker, the less base they’ll be able to handle, and
that’s where the subwoofer really kicks in. If you have a large speaker, it’ll be able
to handle the 120Hz number. If you have a really small speaker you’re gonna need to
cut this down closer to 40. The best thing to do is to play with it and see what works
best for you and see what sounds best.

  1. If your receiver doesn't have a seperate output for the subwoofer, you can run your front speaker wires from the receiver to the "speaker in" jacks on the sub, then connect the front speakers to the "speaker out" jacks. Your sub gets the signal that it uses and then passes it on to the front speakers.

  2. Idiot!!!! get off youtube!!! you don't know jack about the equipment and you don't know jack about how to set it up!!! sorry but you suck

  3. 120 uh…..hertz…uh….number

    LAWLS

    This guy should either do more research so he actually knows what he's talking about or practice his lines more so it seems like he does…

  4. If you have a small main speaker, cut the sub down to 40 hz?? This guy needs to go back to school. Idiot. I have satelite speakers, so my sub is set to 100-120hz. There would be so many mid-low frequencies missing if it was set to 40.

  5. this has nothing to do with crossover settings. What kind of subwoofer? There are a lot of variables when choosing a subwoofer. Depends on budget, sound taste, size of room, apartment or house, what type of speakers you have. Do you listen to rap, or jazz? Is this for home theater, too?

  6. forr my front two speakers they r TECHnics, THEY R AT 240 WATTS AT OHMS i believe, my center speaker is a Pioneer is 125 watts at 8 Onms my surround speakers r Polk audios, not sure how big my room is but i listen to alot of music

  7. get a nice musical 12 inch like a paradigm pdr 12 that will handle pretty much anything u throw at it and its around 500$

  8. my question is .. on the back of the sub, you have that line level input.. with a left and right jack. The problem is.. My a/v reciever has a subwoofter out jack but its only single… how do i hook this up?

  9. Could you provide a brief explanation of the subwoofer crossovers or recommend a site or video that explains how to use the crossover feature correctly? I'd really appreciate it.

  10. this guy just reed the manual fitcures of the woofer(cerwin vega hst- 12), he is right at the phases but that woofer dosnt retein the frecuencies about 40hz to 120hz , just take a part of the signal and the amplifier do the rest. those frecuencies pass too your other speakers the problem is that your speakers dont reproduce that frecuencies. get luky

  11. he says the smaller the mains the lower you need to set the filter on the back of the sub?!? thats the wrong way round. the smaller the mains the higher the subs filter has to be set.
    who sets a sub at 40Hz anyway? you shouldnt really set them below 80 unless your mains are like 15" beasts, which is unlikely because most home theater mains are 8" max. bring back the days of decent speakers!!! he's not very expert anyway. what kind of village is this. lol

  12. Wow My head Hurts with the amounts of BAD INFO . You should stop Giving out info like this. The Xover is based on the the Main speakers. Usually you want the sub to be crossed at about ten Hrz above The speaker input is for a stereo set up that is used for a system with out an LFE out put. It can be also used in a Center channel sub Configuration ( Learned That one at REL ) Have you been to REL? I Guess Not. Do you self a and every one else a favor stop posting Vids

  13. @d4nk1503 Well there is allot you have to consider such as the power of the sub and the power of the amp or receiver. if you have say a 100W sub and a 500W amp/receiver your going to blow your sub, and viseversa. Make sure you check the power of both items, get the right audio cables and then you have a car sub as a home rattler.

  14. @bsod4u2 Yes, you are right, and Clowns Village made my day! lol. Pretty much all their experts just read it off some sheet written by a 10 year old!

  15. @bsod4u2 so what are you trying to say, that the phase should be in reverse if the subwoofer's placed opposite the main speakers?

  16. @kawaiifreak860 If you actually read what I typed you would find out I meant low pass filter. If I set my LPF at 40hz then the sub can play down to whatever frequency, say 15hz, but it will have reduced output at frequencies above 40hz creating a dip between the mains and the sub (unless you have awesome mains)
    Also, wattage isn't everything, someone with 500 watts RMS can beat someone with 1000 watts RMS. It's not just power, it's box, room etc and it has to sound good too. In a house anyway

  17. @kawaiifreak860 fuckin idiot!!! Car woofers and home woofers are mainly different… go fuck your self with your… let me guess 80000 Watt Car sub!!

  18. what sub is he using to demonstrate in the vid? please help!? btw, not to b rude, but u did explain a few things incorrectly 🙁

  19. Expert ummmmmm riggggghhhht!!! Really can you use car subwoofers that is just funny…. you should be teaching this. Probably a highend system to this guy comes from a TIB with a 27" Crt.
