How does N3 bass compare to the x-ls bass, both with no-rez?

[Danny Richie]

-3db on the N3 is at 40Hz while the -3db on the X-LS is in the 50Hz range. The transmission line design of the N3 combined with less moving mass of the woofers will give a tighter and more controlled bottom end as well.

I'm not too good with the technical stuff.  The -3db thing means the N3 plays deeper? 

I find the x-ls a little boomy, unless it has something to do with my room.  I just tried them yesterday with a new amp upstairs(a Music Hall).  I was listening to the ELT 525s with an x-sub and then tried the x-ls instead.  I got that kind off annoying, overly present bass.  This is one of the less pleasing features of the x-ls IMO.  When I upgrade I want to avoid that type of sound.

Thanks for the response.

Yes.  -3dB means that the output of the speaker is down, relative to some output at other frequencies, by 3 decibels at 40 Hz.  -3 dB is about half the output.  See:

Boom may be caused by the room; have you tried moving the speakers (or your position) around?

You can adjust the bass by either moving the speakers further away from the back wall or by stuffing the port.

[Danny Richie]

A boomy sound is not a characteristic of those speakers. You have something else causing it.

What corndog said, most likely.  I do find the MTMs boomy, but then, this is likely cabinet related.

I think I heard or read somewhere that the Ninja upgrades fix the boominess of the MTMs.  I could be mistaken but it might be worth looking into.

Yeah, it lines them with No Rez. That tightens up the whole bottom end.

[dvenardos]

You might want to use the tile method to brace the cabinet to see if that clears up your boominess before you start building new speakers.

Maybe it is my room(s).  Or maybe boomy isn't the right word.  And I should probably say that I rarely sit in the sweet spot

Definitely the bass in my basement room is very dependent on were I am seated.  I get nasty peaks.

When I brought the speakers upstairs I put them on top of  the 525s and the bass had a much more forward presentation.  I was trying the x-ls (encore) with the Music Hall to see how they sounded.  The x-sub was connected.  I didn't keep them plugged in long because I found the bass annoying.  I get the same feeling when hearing the bass from someones far away music or when you get the bass from a car driving by. Is that "boomy"?

The x-ls have no rez.  The 525s don't.   Maybe it is my ears?

Have you considered room acoustics? here goes the wallet ...

[corndog71]

Have you tried them without the x-sub?

[Danny Richie]

Can you post a pick of how they are set up in the room?

Sure thing.  A couple pics just to give you an idea of the room/materials. And then speaker placement.  The x-sub is usually where that little rat's nest of wires is. 

The corner in this pic is where I took the other two pictures from and my usual sitting spot.  Big bass in this corner.  There is a bass trap now where that little radio is.






Sounds best when I sit smack dab centered with the tv, on the couch.  I almost never sit there ...

[Danny Richie]

I picture is worth a thousands words.

You have a rear ported speaker with the port about 6" from the wall. The port output then couples with the wall and gives you a heavy bass hump.

Either pull them several feet out into the room or plug the ports with some foam.

Several feet?  The back of the speaker is exactly 16 inches from the wall.  That's about my limit.  What about some treatment behind the speaker?
Would I have the same issue with the N3s?

The back of the speaker is that far out from the wall? It looks like about the distance of some CD's in the pic.

Treatment right behind the speakers will really help.

If you build the N3 with the transmission line exiting out the front then you will have less of an issue than you are having with these.

Yes measured at exactly 16.  That is a big, old 32 inch CRT tv for perspective...

So a front port and a bit different configuration inside?  Does it change the sound?

You just flip flop the whole bracing system that makes the transmission line. It does not change the sound, but changes the way the output of the T-line couples with the room.
