I understand where you're coming from but in practice, these type of circumstances are easy to fix with a simple, easy to setup solution, tip the L1 down just a bit.

I hope that helps,
Steve

PS Check this post out on a patented device to help with situations like the one you describe.

Thanks Steve.

Living in Alberta cattle country facilitates the sh*ty solution in your referenced post - very amusing

I think the posts made by Larry M are a good demonstration of the limitations imposed by the L1 sound-cylinder when used in the standard configuration. Pitch can solve some of these problems but not all. The performance-level being at the same level as the "wall of dancers" is not solved with pitch along. One needs also vertical-adjustment. Also, the geometry of the 6' sound-cylinder in relation to the audience dictates that the angle between a line perpendicular to the face of the L1 and the floor of the audience must be kept relatively small. Sound from the top of the L1 can reach the ears of the folks at the back of the audience while sound from the bottom can reach the ears of the folks at the front of the audience. It is also interesting that if the stage is too high, one may not be able to achieve the appropriate angle without placing the PAS at a lower level and, perhaps, adjusting height and pitch from that level which may present the problem of reaching the musicians ears with the sound-cylinder.

I guess I'm only stating the obvious here, but I think that flexibility is highly desireable.

Hi Lloyd,

the geometry of the 6' sound-cylinder

Even in metric it's a little taller than 6'

From the product FAQs
How tall is the system when fully assembled?
The system is approximately 83.5 inches (212 cm) tall when fully assembled.

Just a little clarification for those readers who may be unfamiliar with the terms.

yaw: means rotating left-right around the up-down axis

pitch: means rotating up or down around the left-right axis

roll: means rotation around the front-rear axis (like the steering wheel in a car).

You can certainly "yaw" the product all the way you want by simply putting down the power stand in the right orientation.

There are a few case (like raked seating or a very high stage) where pitching can be useful. However, that should be done with caution, because first and foremost, it has to be save. In all practical cases that I've seen a few degrees are more than enough.

It's hard for me to imagine a case where "roll" would be useful. "Rolling" will tilt the overall radiation pattern in a strange way and it is very likely that you end up with spots in the room that aren't properly covered.

I know that sometimes it can be a close call to fit a 7 foot speaker but so far the number of cases where it really doesn't fit have been very rare.
Part of that is building code. In most legislations a ceiling height of 7 feet is the bare minimum for a residential space and requirements for commercial spaces are usually significantly larger. There are always exceptions but these tend to be exceedingly rare.

Hope that helps

Hi Ken, I want to purchase an L1 for use with my Martin acoustic guitar and a microphone. Can the L1 handle both the guitar and mic together and how would you be able to adjust the EQ? Would I need a pre amp or something of that nature? I herd a professional musician use this system at a private party and it was amazing but I didn't have time to ask him about the system. Also can this only be purchased directly form Bose and where can I get one? Thanks for reading my letter and I do appreciate your help...............Tony

Hi Tony,

I'll try to answer all your questions

"Can the L1 handle both the guitar and mic together and how would you be able to adjust the EQ?"

The L1 will easily handle your guitar and vocals, and the eq settings can be achieved using presets for each channel individually. Also, you can further tweak the eq by using the 3 band eq knobs on the remote for channels 1 and 2.

quote:

Would I need a pre amp or something of that nature?

Not necessary, you can plug the Martin direct, and also your vocal mic. The system uses the room very efficiently to create natural reverb, so the majority of players and vocalists use the system with no effects.

I've included a link here that gives you all the available purchase options.

Hope that helps, hope to see you around here talking about your new system soon!

Best Wishes,

I wonder if any of these people could use some Wallacher Guitar Hangers on their systems. Wallacher even has a new MIC hlder for the system.

So I went to check out your new MIC holder. Where is it on your site?

This looks like it could be it Tom
Wallacher.com

All I see is the Bose hanger & the amp stand.

Have the prices come down on those wallacher hangers? Especially the one that closes automatically like a Hercules stand.

Mr. BASS-Dude,
I agree Bose guys that use of my sweater, a block, or whatnot is all one needs to adjust the wide footprint provided by the PAS. My goal is good sound and simplicity. These ideas are great; however, you kill the simplicity when you add complicated gadgets to solve what my sweater would solve in 4 seconds.

LLOYD - I've often considered this same thought. Some sort of hefty clamp/pivoting device with a cable attachment from the base of the column to the power stand. The clamp/pivot arm could then be directed at an angle upward to cover a balcony for instance, or any desired angle. Of course, this approach would have to coincide with the physics of the cylindrical science, if this even makes any sense.

The clamp/pivot arm device would certainly be a pricey machine. I've often wondered how one might address a balcony in a medium sized venue where perhaps there was no house system or main PA and the Bose PAS system was the only reinforcement.

You might find this interesting.

Hello GeezerFaction,

You can not cover a ground floor and balcony at the same time. You'll need to augment by taking line outs of at least the key voices and instruments and sending them to an ancillary system that's designed to cover the upstairs.

The easiest way to think about this is to imagine the wedge shaped radiation pattern of the Cylindrical Radiator speaker and the audience you need to cover.

Tilting works for a raked seating area because you tilt the wedge up and cover the whole audience. But if you try this with audience upstairs and downstairs, you'll cover one but not the other.

Let us know if you need any additional help.

PS - it doesn't look like Lloyd (YerBassicCyberDude) has posted anything here since 2006.

Even better than the 'patented' solution in the above post would be a simple wooden doorstop, because you could adjust the angle of declination of the sound pattern.

Line array loudspeakers oriented vertically are 'aimed' to play to an audience that is an infinite distance away. To aim your L1 in such a way that plays with full volume to all rows of the audience, put a laser pointer on top of your L1 (or imagine one there) and insert the doorstop underneath the rear edge of the Power Stand until it aims directly at the ear of the tallest audience member in the last row. Line-source physics will make sure that the rest of the audience benefits from the consistency of acoustic radiation that the L1 provides.
