I really have to stop reading and looking at the Axiom products...anyway.

I have been thinking on doing some upgrades to my HT system mainly the front mains and adding a second subwoofer. I am currently running a 7.1 system and would like to get a better sound stage and more even bass. Hence the new mains and sub.

My current sub is an Infinity IL100, 10" CMMD driver with a 250w amp. I have read it will go as low as 26Hz but have not seen a graph and it will do 30Hz-100Hz flat +/-1.5dB

My room is just over 2200 cubic feet and I was wondering what the better sub would be to integreat into my set up would be, the EP350 or EP500. I think I know the answer but would like some feedback.

Thanks
Phil

Get 2 EP350's.

One EP500 will overpower your Infinity so much that you'll stop using it and then you'll be back to needing a second sub to even out your bass, so we're back to two EP350's.

There may be some discussion going on right now about this.

Try this 2 to 1

If you want to use two subs, you are better off buying two of the exact same subs. EP350's are a great choice, or something from SVS/HSU/Elemental Designs, etc. Axiom and SVS are easiest to get in Canada, though.

...and Paradigm subs, too. (DSP line)

Adrian, have you seen or heard Paradigms Sub 25? I just read a review about it and the reviewer claimed it is the king of the hill. Although it would take me a little while, I've seriously thought about saving up for it.

I've only seen it online, but it sounds like a real beast. It's in the Signature line so it's going to be $$, about $4G list by the looks of it.

If you've done the sub crawl and the spot is right in front of your seat.......feet up, crank up and your done.

Now other than a massage? That would be the 6K sub and you would certainly be getting, well, you know.

Well, I don't know if it would massage your feet, but most certainly it could part your hair for you.

You know, like Bruce Willis.

Receding hairline. Whatever.

Well womanet (budget) will not allow for two EP350 unless I change the main speakers I would like to get. I know that two identical subs would be best but there is nothing wrong with the infinity and I am sure I could integreat it into the room with the EP350.

Does anyone know what CuFt the EP350 can displace by itself?
Sloped I did read the post you likned and thanks, but I am only looking to get one new sub. I guy can only dream so much.

Later

Phil, there's really no precise "room-filling" capacity spec available for speakers, including subs, and the important point is if it's loud enough at your listening position.

Give it a go with the two different sizes. You never know what will or will not work out until you give it a go.

I have two different size subs in my setup, and was lucky that they worked out. Not ideal, and not easy to integrate, but with some luck, not impossible.

I had a problem with a null around 35hz with my one sub setup that I could not get rid of. In a 'what the heck' moment, I hooked up my old sub, put it back in its old position, and two weeks of tweaking later, I greatly reduced the null.

Phil, when I did my sub comparisons I was at mojo's and his basement is ~4000cf(IIRC) and the EP350 worked just fine there.

Hi All,

I noticed yesterday reading the manual of my Marantz Receiver that they have a feature where some of the LFE output is sent to the front speakers as well as the Sub to give a more even Bass in the room.

They call it SW Plus+.
Posted By: PhillipD Re: Adding Second Subwoofer - 01/27/10 12:42 AM
madjak my yamaha does this as well youcan either set your main speakers to small and have the bass go thew threw the sub or have it set to both by changing the main size to large. I am not sure if it gives more bass but just directs it to the sub and the mains. For me this would be fine if my fronts went wodn to say 35-40Hz, but they don't.

Thanks
Phil

Jak, that isn't what that "+" setting actually does. The LFE(i.e., low frequency effects occasionally present during movies)are played by the sub alone. If the M22s are set to play full range(probably not a good idea), then the "+" setting for the sub has it duplicating the low bass from the regular main channels, along with the main speakers. Probably you'll get better results by using the regular bass management, i.e., having the sub play the lowest bass while taking that burden off the M22s so that they can play the higher frequencies a bit more cleanly.

JohnK,

Tonight I turned that setting to normal and the sound was much better.

I just got the amp yesterday, so I'm still finding my way around things.

So yep, I confirm that you are correct - not that that would be much of a surprise to anyone here.
