Hi, I am new to this forum. I purchased L1 MODEL II with two subs for my live performance in parties, weddings, events, as a one man band (backing tracks). My mixer is TASCAM with mono output, TC-HELICON harmony GXT for my vocals, washburn acoustic guitar, ltd electric guitar, harmonica, recorder flute. I play jazz and blues, folk, during dinner and cocktail with no problem, but for my ballroom tunes (island beat, santana, tropical, swing, rock n roll 60's) plus dj music for filler, I can not get the required bass response to satisfy me and the audience (100-250). I am planning to buy additional sub. Which would I choose? 2 bose subs which will only give addtional 250 watts or the new "EV ZXA1-Sub Compact Lightweight 12" which will give 700 watts sub power and only 46 lbs and 50% lower price comparing to bose subs. My only concern for EV sub if it will perfectly work with the external sub out from L1 systems. Thanks!
You'll want to keep all of the subwoofers together touching/close to touching as possible to avoid any multisource interference.
Then just adjust the volume of the powered subwoofer to your desire. The Bass line out, will send everything between 40 ~ 180hz, so the crossover is already done, but your subwoofer may have an additional control that you can use to fine tune it.
Hope this helps!
Thanks for the tip. So you would recommend going for the EV SUB than the BOSE if my purpose is to increase bass punch and volume. Meaning my set up will be one L1 Model 2 with two BOSE SUBS and one EV ZXA1 (12 inch sub) without affecting the overall shape of the sound which is automatically done internally by BOSE DSP. Or I can set up in stereo. From mixer: Main Left out to L1 and Main right out to EV SUB so that I can control the EV SUB independently from L1. Thanks!
You can do that, but if you're going to use the Bass Line Out (for the crossover) then you'll need to control the volume from the Sub itself.
However, if it already has a crossover built in (which it probably does), then you can run it from the mixer. Also, even if you're going directly out of the mixer into the sub (and not the Bass Line Out of the Powerstand), you may want to insert a cable (or jack) into the Bass Line Out - it may reduce the amount of bass going to the cylindrical speakers giving you a little more headroom - try it before you turn on the subwoofer and see if you hear any reduced bass from the main speakers when there is a cable/jack plugged into the Bass Line Out vs none.
Although you'll hear that the preferred method is all Bose, you'll also find a lot of folks hear having great success with third party subwoofers - I did my own experiment with subs and even a bass amp in another thread.
Hope this helps.
Thank you for joining the Forum.
Thank you for all the information. That's a lot of sound for one fellow.
It's not always meaningful to compare wattage for different devices (loudspeakers) as this is (usually) a measure of the power going into the loudspeaker, not a measure of what comes out. In this case the ratings you mention are for the amplifier output, not a measure of the actual sound produced by the loudspeaker.
Perfectly - no. The only thing that will work perfectly is the system that Bose created to work with the L1®. There, you have a perfect match for the gain staging, power, loudspeaker characteristics, designed from the ground up, in the Cylindrical Radiator®s, the Power Stand, the PackLite Amp, and of course, the B1s.
Looking at the EV ZXA1-Sub web page we can see that the Frequency Range (-10dB) is 44Hz - 118 Hz. The B1 Frequency Range (-3dB) is 40 - 180 Hz. (upper frequency determined by the crossover in the Model II Power Stand). If we go by the specifications alone, one could guess that at -44Hz, the ZXA1-Sub output is less than half the rated output (-10dB) and the B1 would be closer to three quarters (-3dB) of the rated output.
Now we could go on for hours about how this might sound, in terms of perceivable differences in volume, and I don't think that discussion would get you any closer to an answer. But even if everything thing else were the same (EQ curve, speaker efficiency, and more), and they are not, the difference between 200 and 300 watts input wouldn't very much in terms of absolute volume. Besides, you would have to be running both systems at full power to get to that point. How often do you run any system at 100%.
As a matter of interest the B1s go down to 32 Hz at -10 dB. (references). So that introduces another layer to the discussion in terms of how much usable sound your audience could perceive and appreciate at that frequency.
So back to the question of a perfect match: If you want to have the same spectral balance of sound across the frequency range as you have now... only louder - this is exactly what the A1 PackLite Extended Bass system is designed to do.
If you want more bass without raising the relative level of the sound above 180 Hz, (sound from the Cylindrical Radiator®s) then you can try a third-party sub.
Note: If you do want MORE bass at the same volume out of the Cylindrical Radiator®s, then you probably want to run the sub directly off the mixer so that it is NOT running through the Power Stand (with it's built-in tailoring for the B1 EQ, and attenuating the output of the B1s). See Bass Line Out for more details.
You also would NOT want to put a jack plug into the Bass Line Out while running the sub from the mixer. Doing that will cause the Power Stand to reduce the output of the B1s attached to the Power Stand. While that makes sense if you are trying to maintain the overall balance of the sound, it doesn't serve you if you are trying to emphasize the bass.
We have an article that addressess many of these points all in one place:
