L1 Model II

Let's talk about the L1® Portable Line Array Systems

Using proprietary Bose® technology, L1 systems combine  PA and monitors into a single, highly portable unit. The  loudspeaker can be positioned behind or to the side —and you hear what the audience hears.

Highly portable PA and monitor combined for solo performers, DJs and general-purpose use. Fixed vertical control with 180° horizontal coverage Reduced vulnerability to feedback.

Three systems to choose from (Compact, Model 1S, Model II)
Two passive bass module options (B1 or B2)
Consistent coverage and tonal balance, portability and easy setup.

Hello everyone,

Happy owner of a L1M2B2 system. Just recently took ownership after buying if off a friend who didntd use it all that much so it was essentially new. We use it for every jam and have only used it out of the house once. So in the jam space we only run vocals and kick through it. Kick is setup with the Beta52 preset, and a compressor, as the kick gate doesn't play nice with my current drum. So the issue is the B2 is now producing a smell from the front ports. It's seems to have been getting worse as of late. The trim is set to peak in the yellow and the gain and master are around 50%. I'm wondering if anyone else has this issue. Our bass player had an old amp and I had an old studio sub that both produced the same "warm/clippong voice coil" smell. Both manifactirers said it was normal and just the smell of the glue and ply escaping from the ports. I've got the Bose plugged direct into the wall and into its own outlet. Any ideas would be great. Really hoping the sub isn't dying.

P.S. using the speaking cable that came with the system. Latest T1 and power base fw. 

Thanks everyone.

Hi Boy_Narf,

This sounds unusual for a B2. If the unit is less than five years old, it's probably still under warranty. Please call Bose Support tomorrow and see if they can help.

Well they want $130 to fix B2 as I'm just about a year out of warranty. Not overly impressed with the quality of these things. It has only been used on a regular basis for the past year and already has issues. Really a shame. I can find a used B1 for the same price so might go that route instead of paying for a repair and being without a system.

Yes I'm fimiliar with the B1, B2 comparison due to my previous shopping experiences.

No they just gave me a repair price.

Usually this kind of smell is produced by a clipping amp over heating the voice coil. The mixer isn't clipping I made sure of that but I have had it set on + mode since moving into our new house. Is the + mode only suited for low volume listening? Perhaps the B2 can't take + at medium levels causing the coils to overheat and produce the odor.

I wonder if they will give me a discount to send in the entire unit. I would hate for the sub to be fine, waste money, and have to send in the power base at an additional cost.

I had a problem with my system when I first got it. The sound would cut out randomly for a split second and then be fine. This would happen once or twice in a performance. They were not sure what it was but decided to start with what was still under warranty. It was the B2. They sent me a new one and problem solved. At this point, I am considering a 2nd entire system because we gig so much it would be nice to not only have a backup but to actually leave one system at a gig we play at every Friday. Looking at used systems first.

I've had the cutting out issue as well but only when the system is plugged into a power bar. Once I put it in a dedicated wall outlet it's been fine. 

If I was still under warranty I wouldn't be having this conversation I would have already sent it back to get it replaced/repaired. It's the < 1 year out of warranty that is the issue. Guess that's what I get for buying used.

Hi Boy_Narf,

I'm sorry you're disappointed. No one here can speak for Bose Support.

The position of the B2 bass level switch should not be the cause of the problem.  You should be able to run the system at any position at any volume.

Please call Bose Support again to see if they have other options for you.  Tell them your concerns about the power stand. Also check if they have an alternative to repairing the unit.  And ask about the warranty on the repaired or replaced unit.

Called back. $138 CAD for B2 repair is my only option. They do not offer refurbished or trade in on the B2. I also expressed my concern about the power-stand potentially having an issue causing the sub to overheat and he advised me to unplug the B2 and check for a smell. Of course it won't produce a smell if it's unplugged. He didn't seem to understand that a faulty amp sending out a dirty or clipped signal can cause a speaker to produce a smell.  

I also asked about sending in the entire system and he said there is a flat rate for each part. So if I send the entire system in at the same time, or piece by piece, the price will be identical.

Also, what a noisy call centre! Background noise makes it quite difficult to hear the analyst on the phone. Neither tech asked me about mixer settings, or what gear I am running through it. They went straight to repair. I would assume they would want to do some basic troubleshooting before taking my money, you know? 

If anyone with the same system has some time would you be able to crank it up a little and let me know if there is a smell coming out of the B2 ports? I've read a ton of reports about the F1 systems smelling. Plus the fact that I've never driven this system hard makes it unlikely the coils have been damaged. 

Thanks,

Will you get a warranty with the repair? That might be a factor if you're considering replacing the B2 with a used B1 purchased privately.

Of course it won't produce a smell if it's unplugged. He didn't seem to understand that a faulty amp sending out a dirty or clipped signal can cause a speaker to produce a smell.  

The L1® Model II has built-in limiters for each amp. If one of those fails, the trouble light on the power stand would come on and there would be no sound at all.  There's very little chance the issue is with the power stand.

Also, if the issue was with the amp clipping, you would probably hear some audible distortion.

Given the symptoms you mentioned, it's unlikely the problem is the signal chain ahead of the L1.  You talked about the KickGate. So that tells me you've got a T1. 

They went straight to repair. I would assume they would want to do some basic troubleshooting before taking my money, you know? 

I'm sorry you're disappointed with the interaction with Bose Support. I will send your comments through to the support team.

I have a L1® Model II with B2. I've had it for years and run it in all switch positions at all volumes low and high. I've never had an issue with a smell coming from the ports.

1 year warranty with the repair. Thanks for your attempts to smooth things over. Hoping to sell some gear over the holiday to fund the repair.

I had the same issue with a Yamaha studio sub. Sent it in twice and both times they said it was normal. That is my worry about paying $140. They will simply send it back saying checked out okay.

Good news! I found a business card from the fellow that sold me the system. The purchase date is August 1, 2014 meaning it's technically still under warranty! I'll be calling support tomorrow and sending them the receipt. Hopefully they will honor the warranty.

Well the sub has apparently arrived at the repair facility according to my tracking number, but no word back yet...

What I will say is that I ran into another problem with my power-stand and cylinder speakers. I did some research and found out you can run it without the sub. Figured I would turn it on last night to see how it sounds. Upon first power up, no sound came out. The trim light was green (had a chrome cast audio playing) but no sound. I turned off the power stand, turned it back on, and the music started playing. Really sounds terrible without the sub Few minutes later I remembered that this has happened quite a few times even with the sub attached. 

Any suggestions, or things I can check? I'm thinking it might be the T1 failing to send the audio signal to the power stand. Or could there be something wrong with the stand?

In the mean time I've pulled out my 100 watt yorkville micromix and 20 year old warfdale speakers. I sure miss the L1 hahaha.

You may not hear anything until the returned unit arrives.

The L1 Model II is an integrated system (Cylindrical Radiator® with the Power Stand and at least one bass module (B1 or B2). It is not intended to be used without a bass module. You won't harm anything except your reputation running the system without the bass module. But there's no good reason to do it.

This could be a problem with the T1 or the Power Stand. If you have another signal source (keyboard, other electric instrument, another mixer), you can connect this to the Model II Power Stand Analog input.

That will have to do until the B2 comes back.

Well just got an email saying the repair was completed, and it is OTW. I of course called in to see what they found. First analyst to answer the phone said they did nothing, just tested for 10 minutes, said it checked out okay, and sent it back. He said if it's still happening to send in the powerstand. He then transferred me to a technical analyst who said they did some work on the amp (I thought the amp was in the base???) told me to test when I get it back and send the powerstand back in if the smell is still occurring. 

So, not really sure what was done haha. I'll report back when it arrives.

It has arrived!!! 

The sheet included says it has been "repaired if necessary". They also packaged it up like new! I thought they sent me a brand new model until I had it out. Nice pack job!

I've had it on for about 20 minutes now with some bassier music and there is no smell. Prior to sending it in the smell would be present after only a few minutes so this is looking good! I'm going to call them back after lunch and see if I can find out what they fixed. At any rate I'll report back after the next band practice. I first noticed the smell after micing up my kick drum.

Okay! First hand band practice with the returned B2. No smell from the sub. I got a follow-up email from the tech line and they said all Bose items returned for warranty are fully dismantled and if necessary parts are upgraded to the latest and greatest. Everyone I've spoken with said they didn't do any repairs, so the process of taking it apart and putting it back together resolved the issue. Sub working perfectly with no smell at all. Wonderful! Now that the sub has stopped stinking, I'm noticing a faint smell from the power stand. Kind of like warm electronics/dust. I have done my best to spray out the vents with compressed air so there shouldn't be much inside. What do you guys think? Should I call and get the base checked out? Or pretty normal for an amp odor at higher playback levels?

Thanks.
