middlebear Posted January 1, 2015 Share Posted January 1, 2015 Can someone PLEASE test this on your l3t. My new l3t TOP speaker produces no vocal sound when I plug in a mic or play a cd with vocals. I understand the horn and two woofers are three way and will sound different however I'm not sure if the top speakers is working correctly. The vocals come out crisp and loud on the bottom woofer and the horn. The top speaker does product a light mid to low vibration for my acoustic guitar however it's very light and no vocal sound occurs and I've tested ALL modes. Also, is the top speaker woofer 1 as explained in the next sentence? (Woofer 1 - everything below 250hz, Woofer 2- 250hz to 2.2khz-7.okhz and Horn-2.2khz-7.0khz depending on speaker mode.) I'm fixing to return to line6 for repair however if someone tests this and finds the same result this will save me the time and shipping. It may help if you put your ear up to each speaker to find the correct driver location and make a light pencil mark prior to testing.

dboomer Posted January 1, 2015 Share Posted January 1, 2015 Yes the top driver is woofer 1. Try playing a test tone at 100hz and then take a listen Quote Link to comment Share on other sites More sharing options...
padolin Posted January 3, 2015 Share Posted January 3, 2015 i had an issue with sound tonight and found out it was just a switch thing. Check the stereo / mono switches on the back of the speakers. I like the line 6 speakers, but they have a steep learning curve. Quote Link to comment Share on other sites More sharing options...
middlebear Posted January 4, 2015 Author Share Posted January 4, 2015 Padolin, PLEASE plug I a mic in to your l3t and tell me if you hear any vocal sound coming from the top speaker. (or play a cd on playback mode and let me know if you hear any vocals on the top speaker.) The middle horn and bottom woofer produce vocal sound however the top woofer is silent as far as vocals. My eq and mod knobs are all around 3 o'clock. Dboomer, thank you for the excellent advice. I miked and recorded a 100hz sound from youtube via ProTools then burned on a cd then played from a cd player via rca jack on playback mode and the 100 hz sound came in strong in all three speakers. This is confusing, if I can confirm one other l3t does not produce vocals on the top speaker then I'm assuming that's the norm. Quote Link to comment Share on other sites More sharing options...
dboomer Posted January 4, 2015 Share Posted January 4, 2015 I would not expect to hear vocals from the top speaker. That is normal for this system. Quote Link to comment Share on other sites More sharing options...
middlebear Posted January 6, 2015 Author Share Posted January 6, 2015 I plugged in a bass and tested via PA and Electric Guitar modes and it's really faint on the top woofer. It seems the crossover should have a higher output signal to that speaker. Strange the 100hz sound outputs well in all three speakers. Nevertheless, if I can't find someone from this forum to test on their l3t speaker in a couple of days I'll ship it off to Calabasas CA.

padolin Posted February 1, 2015 Share Posted February 1, 2015 Middle, ive been out of the loop. do you still want me to test that speaker?? Quote Link to comment Share on other sites More sharing options...
middlebear Posted February 1, 2015 Author Share Posted February 1, 2015 Thanks Padolin but not necessary, they have already been shipped. Quote Link to comment Share on other sites More sharing options...
padolin Posted February 1, 2015 Share Posted February 1, 2015 what was determined? did you have a bad cross over or a bad speaker?? Quote Link to comment Share on other sites More sharing options...
middlebear Posted February 1, 2015 Author Share Posted February 1, 2015 Undetermined at this time, they have not been returned however that's my suspicion. If you have time plug in a bass guitar or mic, listen to the top speaker in various modes and share the results. Maybe we can save someone else $80 on shipping.

middlebear Posted February 4, 2015 Author Share Posted February 4, 2015 L3t speaker returned shipping from Line6 today, tested it and found the same results. Plugged in bass guitar and no top speaker sound 'or possibly very faint sound'. Plugged in a mic, same results. Top speaker has no hissing sound like the horn and bottom speaker when volume is cranked up. I'll check with Line6 tomorrow on the status, the PO had no information on what was done. It's possible it may have been tested and this is the expected result. Nevertheless, if anyone from the 250 plus hits has an L3t please plug in a bass or mic and test the top speaker, it takes about two minutes to test. I have renewed interest in your findings.

dboomer Posted February 4, 2015 Share Posted February 4, 2015 I think you have normal operation. You made a test yourself and did hear 100hz from the top speaker, right? The top speaker is designed to come on only on low frequencies. Quote Link to comment Share on other sites More sharing options...
middlebear Posted February 4, 2015 Author Share Posted February 4, 2015 Thanks dboomer, as mentioned I plugged in a bass guitar with very little if any output on the top bass speaker. You are knowledgeable on this product and when you didn't respond after I mentioned the bass test I assumed there could be an issue. Also, the 100hz output test did produce sounds on all speakers as well as the non-bass speakers (2- 250hz to 2.2khz-7.okhz and Horn-2.2khz-7.0khz) which was interesting. Nevertheless, if someone else would have responded with the same results I would have closed this issue without question. Quote Link to comment Share on other sites More sharing options...

litesnsirens Posted February 17, 2015 Share Posted February 17, 2015 OK, this brings up all of this brings up a question to me. I understood from the get go that the top speaker on the L3t was the sub-woofer so to speak but the following never occurred to me. What does that top speaker do if I use it in conjunction with an L3s? Is it still pumping out below 100hz? does the crossover get reconfigured if the L3s is plugged in so that the top L3t speaker takes over more mid responsibilities, or does it really do nothing at all since the L3s is taking over below 100hz and therefore anything above that is not getting through to the L3t? It might make me reconsider whether I really need L3t's or if L2t's would do the job. In other words is there a difference when using L3s subs whether the tops are L3t or L2t? Just curious.

dboomer Posted February 18, 2015 Share Posted February 18, 2015 Remember that speakers do not "stop" at the crossover centerpoint. So with an L3 the "woofer" driver is operating over about 2 octaves when the crossover is set to 100Hz. The difference between using an L2 and an L3 over subs is that you will get an extra 3dB of output in those two octaves from 250Hz down by using L3s. You can also play with the crossover point. It depends on your musical style but for some people that may benefit by manually shifting the crossover point down to 80 Hz. Personally I prefer to pick a crossover point that keeps as much of the low vocal range out of the subwoofer so I generally prefer crossover points a bit on the higher side. But for the flatest, most powerful response you may prefer to go a bit lower. It's a personal decision. Quote Link to comment Share on other sites More sharing options...
litesnsirens Posted February 20, 2015 Share Posted February 20, 2015 Thanks Don, that explanation is helpful to me. I will just point out that sound-wise, I am not looking for any improvements, my system sounds amazing and I have no need to play with crossover points. My questions was more to do with portability, if I were to scale down my L3t's to L2t's it would be a little more room in the car and a little easier setting up. If I need to just go for a jam outside of my own band situation I tend to just take an L3t. I use to take an L2t when I was still using them for floor wedges. So based on what you're saying, if I did down-size to the L2t's I would be giving up 3db in the 0-250hz range, of course some of that wouldn't be audible but it might be felt. It's hard to just imagine that impact, but essentially that's what I have to weigh against the portability issue. Quote Link to comment Share on other sites More sharing options...
dboomer Posted February 20, 2015 Share Posted February 20, 2015 You are correct that a 3dB difference in "average" SPL probably isn't noticeable, a 3dB increase in dynamic range might be. Doing Live Sound is always about making compromises. Normally I use L2s over L3s, but it depends on your material and how loud you need to play. I would say that I have also used single L3t over a pair of L3s. This is a case where an L2 probably wouldn't hold up as well. Quote Link to comment Share on other sites More sharing options...
