Axiom Home Page Forums General Discussion Advice from Axiom Owners If you had a choice on subs

And can save in one year for a EP600 would you take a verticle EP600 for in the center of the screen or take two years and buy two EP 500's one each year for each side.
Are there any stats on two EP500's in a room.

John (not sure of his last name) on this board has done numerous experiments with Axiom subs.

2 EP500s are better than 1 EP600 for better distribution of LFE in the room.

EDIT:

Found the post from Jakeman:

1. 4 ep600s
2. 3 ep600s and 1 ep500
3. 2 ep600s and 2 ep500s
4. 1 ep600 and 3 ep500s
5. 4 ep500s
6. 3 ep 600s
7. 2 ep 600s and 1 ep 500
8. 1 ep600 and 2 ep500s
9. 3 ep500s
10. 2 ep600s
11. 1 ep600 and 1 ep500
12. 2 ep500s
13. 1 ep600
14. 1 ep 500

two subs on opposite walls will do a better job at taming peaks and nulls.

I should have kept my darn 350 when I had it....

One 500 and a 350 somewhere in the room I would think would do better than just one 500. Don't get me wrong, the 500 is awesome, but my room is huge, so it is probably comparable to a 350 in a small room.

Ok cool I will probably go with the 2 EP500's spending $4000 my wife would probably shoot me anyways not that $3000 is any better but, at least I'd live.

Actually I can get a left over EP350 for $450 tx incl and put that in the rear and the 2 EP500 up front

If you order from Axiom's factory outlet you will save 10%. Troy, my room is 8100 Cu Ft and one 500 does a good job.

yeh, I think my room would be 2400 cf so one would be enough , but I hate the fact of one. I guess I need to place it better in the room just I like if a bomb explodes on the right side of my screen I want to hear that it originates from the right. but then I need decoding and a amp that sends mono signals to the right sub channel only. And I know low frequencies are omni directional blah blah blah. But put it this way if you are walking down a street in say ... whatever town and you were blind folded and a bomb goes of on the right side of the road. you can tell it came from your right you don't hear the low end all around you it comes from the right and you can tell hence left and right channel subs. And I want a sub ( two EP600's be good ) that when the bomb in Behind Enemy Lines goes off to my right to actaully shake the shirt on me from the lower 12 hz of air movement I want to feel and hear the wind go by from my right to the left

I'm not going to go into why your incorrect about freq's below 80hz being not directional, but just an fyi, they are not, and there are plenty of articles from AV professional engineers and scientists which can prove your wrong with factual statistics, not just blah blah blah.

And with Blue ray and the 8 audio channels there has to be a way to have 2 or 3 mono low frequencies channels. And the Reciever engineers and sound engineers have the capabilities and technology to make it happen. if not move over George Lucas, I will show you what sound is spose to be heard like. There problenm is they are stuck on hearing the sound , well I want to feel the sound too, hell I would even like to have fans in my room that are sound controlled so when there is a breeze they come on ..yeh right

... and from there it's only one small step to 5 channel smell-o-vision.

I said 5 rather than 5.1 because I sure wouldn't want to be sitting near the smell-o-vision equivalent of a subwoofer

"I'm not going to go into why your incorrect about freq's below 80hz being not directional, but just an fyi, they are not, and there are plenty of articles from AV professional engineers and scientists which can prove your wrong with factual statistics, not just blah blah blah."

I am just going by what the sales people mention and actuall some conniseurs here mention that if I bought one EP 500 or 600 and position it well I should not notice the direction that the sound is coming from. But, you can tell.

I deally I should have 7 subs and not use the LFE on the amp. Hook all subs up via the speaker wire from that specific channel to the line level on the sub and then use the crossover in the sub. That way when sound goes to the left rear channel and the frequency goes say below 120 hz I hear bottom end in the channel in that specific location. Or if there is a bomb going off on the right hand side of the screen the RF RR RR channel subs would all produce some bottom end and the left channel sub wouldn't do anything. Why produce bottom end sound from a sub on the left when the bomb is going off on the right side of my screen.

I think one of the elements that you may be missing is that an explosion isn't one incredibly deep frequency. It is a loud sound that is made up of many, many different frequencies, quite a few of which will be well above your LFE crossover. *Those* frequencies emanating from your speakers will provide the aural clues that the explosion is happening off to the right.

The deep rumbling bass will just ripple through you, but those other frequencies will be what make you turn your head to the right. Ever been in an earthquake? I used to live in the Bay area. Trust me, I was never able to discern the direction of the epicenter based on hearing/feeling those very, very low frequencies.

I'm willing to entertain the notion that frequencies below 80Hz could be directional. I'm sure there IS a lower limit, but I'm not necessarily committed to the idea that 80Hz is IT for Everyone. It's just too convenient.

Frequencies starting around 80hz and below are omnidirectional. This has been discussed many times and confirmed by Alan from Axiom on many of the Axiom Newsletters. Also, if you do a google search, or check websites like Audioholics, Ecoustics, etc., this has been covered on the topic of bass management. On reason that 80hz is the norm, and setting speakers to small, is because the smaller drivers CAN'T move the air like the sub's larger driver. This is the purpose of the sub, to MOVE air. You feel this and it is NOT directional. Believe what you want Troy, but your are incorrect, and most likely what your hearing, what Rich describes, is not true LFE below 80hz. The hip/hop *** you listen to is NOT LFE, just an fyi.

A good test is put in Styx's Renegade and listen to the first minute, that is low stuff. Or put in Nemo and watch the seen where Darla is tapping on the Aquirium, now that is killer LFE and it will go right through your bones. You can not tell the direction of the source.

As has been said, those very low frequencies are omnidirectional. The reason that we can locate a bass drum, etc. which has a very low fundamental frequency is that the higher harmonics of the fundamental(reproduced by the regular speakers)are directional, as Rich suggested.
