Facing subs > < sound differently?

If I face two 10w7s with the cones facing each other in the sides of my trunk will it sound any different than if i was to face them to the trunk?

Not any more likely than facing any direction, unless of course your trunk is 20' long. Bass frequencies are way to long to blanket it that way. It might be fine to shoot them that way, but it probably will sound better another way--read pointing rearward usually.

I would not face them to eachother...usually in a car, towards the tail lights is best...

if you face them towards each other in a like polarity, then it will sound like poo because they will cancel each other out. What you have to do is reverse the polarity so that when one sub is in, the other is out.

Facing subs towards eachother is bad one cause of polarity issues.... also cause it DOES abuse the subs pounding on eachother.

only if you mean an isobaric type enclosure...then yes, you will be about 3 bd quiter, and need twice the power to regain these losses

That's not true.

Unless, like Polecat mentioned, you are referring to isobaric loading.

Otherwise..no, no need to reverse the polarity. You will want both subs wired in phase with each other.

If you wire them out of phase then you get a positive and negative audio rip heading towards each other that will cancel.

im talking about if they are facing towards each other, where you would need the woofers in opposite polatiry so that the waves are not crashing into each other which causes cancellation. Which is what you would do in an isobaric enclosure.

if you wire one outta phase, you just loose alot of output from that driver.....

The waves are not going to cancel each other out. As B&W pointed out...if you have one sub pressurizing the air, and the other sub decompressing the air...then you will have cancellation.

Wire both subs in the same polarity if they are facing each other on opposite sides of the trunk, like is being discussed. You want them compressing and decompressing the air together, not fighting each other.

Which is what you would do in an isobaric enclosure.

Yes, you do that in an isobaric enclosure. Different situation being discussed here though.

this is when you would wire one out of phase. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
