Hello. Needed some help to set up my new Outlaw LFM 1 EX sub. I have it in a fairly large room and it sounds pretty good, however I am not getting that rumble feel during great action movies.

My question is should I set it to Max output or max extension? Also I left the port plugged that cam with it. Should I take that out? I am not looking for the bass to be super loud, however I would like to be able to feel the bass.

Please let me know what suggestions I can make for settings. Thanks.

Fred

According to pg. 8 of the owner's manual (PDF):
- with one port plugged, use the Bass Extension mode;
- with both ports open, use the Max Output mode.

(Do not use the Bass Extension mode with both ports open.)

Try each one in turn, being sure to re-calibrate your system each time, and go with the one that sounds best to you.

Great. Thanks.

Does one mode provide louder bass and the other provide lower bass? What does the porting do? If I want more rumble should I go with max extension? Thanks.

Yup. Max Output lets the sub play louder while not digging quite as deep. Bass Extension lets the sub dig deeper while not playing quite as loud (although it should still play pretty loud).

The ports determine the tuning frequency.

Great. i have it plugged in Bass Extension now. It is loud enough but I feel it is lacking the deep "feel" bass. I will try max output and see if that changes to what I am looking for better.

Thanks for the info.

Max extension will not be as loud but will go down to 16hz -2db. Max output will be louder but will only go down to 22hz -2db.

I have 2 Pluses and both of them are in max extension.

Also be sure to read your manual. If you have the switch in the wrong position compared to if your port is plugged or not you could damage your sub. Port plugged switch MUST be at Max Extension. Port unplugged switch MUST be at Max Output.

The porting is what tunes the sub to be able to hit certain low frequencies. Like max extension mode will hit 16hz -2db but the port is tuned for 18hz. This means that around the 17 - 19 hz range there will be air and sound coming from the port. But lets say at 40 hz or any other number the sub will pretty much act as if its sealed and nothing really comes out of the port.

If you have a large room you will probably need to go with max output to fill the room better. Sub location and room size are huge determining factors.

But MO mode won't necessarily give you any more volume if the sub is configured correctly, because the output should be level matched either way by your room correction software on your receiver. The advantage of MO mode is if your room is so big that your sub is challenged--reaching its limits--the MO mode will let it get a little louder before reaching those limits. In fact, with MO mode, you might feel less because your sub will no longer be producing some of those lower frequencies enough to benefit from them--you've shortened the frequency range.

So how big is your room in cubic feet (volume)? How far away are you seated? That can tell us a little more. I would bet other factors are a problem. For instance placement in the room or the way you have it configured otherwise.

if you want the punch than that's around 50 to 60hz. Room rumbles is around the 20s.

All in all set it to what you like

I personally use me mode but also have an mbm for mid bass

No subwoofer I've heard has been able to produce the bass I've experienced in the Corps!

Must..stop...buying...every bluray release...

You might try nearfield placement. That means placing the sub within 4 feet of the listening position.

The room is 15 x 20 with vaulted ceilings of 18 at the highest point and about 8 at the lowest point. The sub is about 8 or 9 feet from the main listening area

For that size room, which I suspect is open to other areas, that one sub will not come close to what you are seeking. Like Spyboy said best you can do is move it nearfield.

Before spending any more money the OP should try nearfield placement, the cost of which is zero. The OP said the sub was 8-9 feet from the main listenging area. If he puts the sub really close that might solve his problem. And if not a second sub may be in the budget.

You noticed I never said anything about additional subs in my OP. I could not help myself after that last post.

Agreed. There also may be other placement options that will work. The EX was rated by Audioholics in rooms up to 5,000 cubic feet. Granted each room is different, but it works in mine that is a 6,000 with some good rumble and bass effects. It doesn't pressurize my room, but I can definitely feel it from 11 ft away.

Hi agrandal, what receiver do you have and what are the settings? Depend on model of your receiver, did you run auto setup? Are the front speakers set to Large or Full? What's the reciever subwoofer trim level set at?

I am using the Denon 2112. My volume settings on the sub are 12 o clock position. i did run audyssey XT but the sub came back with a setting of like minus 12, so I adjusted it a bit higher on the receiver settings as it barely sounded.

Turn the subwoofer volume knob down to about 2.5 or 3 (NOT clock position) and rerun auto setup to get sub trim closer toward "0" (-3). Then after adjust receiver sub channel trim if needed.

+1

Many Outlaw owners have found that this technique greatly improves the sound of the sub. Even if you think the gain (volume) on the back of the sub seems really low, ignore that and shoot for the -3db to 0db result from Audyssey. This best optimizes the gain on the sub for the input from the receiver.

Then once that is achieved, trying bumping up the sub channel level on the receiver 2db or 3db if you need a little more bass, but don't change the gain on the sub.
