stupid question

[buntech]

A stupid question is it possible to hook up four subs two for the fronts two for the backs or would it just be over kill:eek:

[ben62670]

It can work very nice. What kinda sub amplification?
BTW Welcome to Club Polk

[buntech]

I do not have any amps yet all I have so far two Monitor70 for fronts two Monitor60 for the backs and two psw10 and CS2 Center Channel

[ben62670]

You have two powered subs, and want to get two more?

[buntech]

over kill

[ben62670]

Bass is directional. If you configure your surrounds to large, and use the speaker wire hookup on the subs it would work well. On the fronts you could just use the sub out LFE.

[buntech]

cool thanks

4 subs will work nicely. Just make sure they're the same model. I wouldn't hook 2 to the fronts and 2 to the rears though. I'd hook either all of them to the LFE out, or all of them to the fronts set to large.

If you have a rectangular room, the optimal setup for smoothest bass response over the largest area is one subwoofer at the mid point of each wall.

But for maximum output, stack them all together, preferably in a corner.

There is no such thing as a stupid question. :D

That actually sounds like a good idea - stack all four of them in the corner:eek:

[mmadden28]

Better reinforce the floor joists in that corner :eek: ;) :D

You have to be careful how you place them or you can end up with unwanted nulls in your room.

Have you thought about one big powerful sub verses 4 psw10's

"Bass is directional. If you configure your surrounds to large, and use the speaker wire hookup on the subs it would work well. On the fronts you could just use the sub out LFE.3"

I'm sure Ben made a typo above. I type like shit too. True bass is non-directional up to about 110Hz. Meaning you won't hear the location of the source. With multi subs there is an issue of low freq harmonics (which some folks think sounds good) and standing waves in normal sized rooms. The best location for a sub would be in the seat next to you or as an ottoman but.......... The wife didn't like how hard the top of it was.jk. So what I found after many, many manuvers of the beast(15") was that it sounds best 4" away from the front wall and dead center between the 2 front speakers.

Idle Thoughts.

[ben62670]

Wasn't a typo. You can hear feel where mid low bass is coming from. If you can hear it you can pretty much tell where it is coming from. Also running multiple subs in different locations can help fill the voids a single sub can have. A test CD with sine waves can help with setup. It is much easier to have a single sub, but if you take a little time multiple subs can be adventitious. Corner loading is better than having a sub in the middle of the room. Try moving it around even just a little, and you can try the phase switch.

As I said Ben, TRUE BASS 18HZ to 110HZ is non-directional. I'm not talking about mid-bass and neither is this man asking the question. Yes I can feel the bass from my sub but, when I close my eyes and listen, I hear the bass everywhere in the room.

I have to disagree. I can hear down to 40hz no problem. When running sine wave tests on my sonosub it was easy to tell where the sound was coming from at 40.

I did numerous test on the beast;)

It's OK to disagree. Everyone has their own veiws on audio. You probably "hear it" beacuase I bet it jammed in a corner. That doesn't reiforce bass, it accenutes it.

Here's a man that has put over 30 years of his time into researching electric theory and parts. Ask any real professional audio reviewer he will say he same. I'm not talking about CNet either.

Everyone here can get something out of it from reading this. He's generous enough to have a free site full of facts/fiction and theory. I've read the whole thing... among thousands of other technical pages over the course of my 26 years after graduating from Texas Tech's Engineering Dept. I have a BS EE and a minor in E Tech. I don't come close to being a know it all, but I'm a stikler about mis-information.

BTW-Like the big cylinder sub. HSU proved that works better than a box. Was it a PIA to tune?

It's all good. Some engineers should stick to driving trains:eek::p:D For every paper out there that says one thing you can find another that says something else. My best advice is to try it for yourself, and trust your ears. Not me, not you, not some piece of paper. I could walk around a room with an SPL meter and show the results. Maybe in an open area your comments may be true, but in a living space the directionality of a sub(which is usually set to 80hz or below) is directional. YMMV

[Polksaladanni]

Yeah well, some audiophile engineers love music and not booming HT noise and most know what they are talking about if they have a for love music. An SPL meter is for measuring loudness (SPL) that have nothing to do with localization. Differences in readings are most likely sound blockage from furniture or sound dampning/curtains or just different distances from the sub.

Your right, it's all objective with audio and related parts.

Personally, I think you are a lot like me in the fact you build things and get satisfaction from it.

But I'm beating a dead horse here.

If you reread my first post. I HAVE experimented with my sub placement many times in the old house and new one AND, I found both times it works best for me dead center between the 2 mains. Both rooms were at least 22x28. I don't go for the big boombooms anymore I like tight full musical bass. Even though 2 clicks up will make my wifes chest look like a bobblehead doll.

Here's the only review I can find on my sub now. Maybe it will help with what I like in subs.

Cool!:D

[goingganzo]

the easest setup would be all four stacked in one place or layed out across 1 wall. and sence bass is omnidirectonal it wont matter where you place them. you can corner load them to get a boost if you want but might caues spikes and nulls

[PolkThug]

I have heard a good room where you couldn't tell where the sub was. So, in THAT room, the 'non-directional' aspect held true, it can be done.

[mmadden28]

The same can be said for 2 channel stereo, where when properly setup you can't tell if the sound is coming from the left or the right- so does that mean that the left and right channel standard speakers are also non directional? :rolleyes: ;)
