Peavey RBN112 I know these have been out for a while, but what is a Ribbon Driver? Is it superior to the compression driver?
Thanks

There are basically 2 types of ribbon drivers. Here is the basic principle of one type

To improve the efficiency an aluminium voice coil circuit is etched on to a planar substrate (see attached picture).  Here is an example of these types.

The second type is a pleated ribbon or air motion transformer.

The advantage of ribbon drivers is they typically have much lower distortion than compression driver and a much better impulse responses and waterfall plots.

The main issue with ribbon drivers has been their lack of efficiency and power handling compared to compression drivers, but some of the newer drivers are now quite good.

Ribbon drivers are more or less a line sources and as such tend to have narrow vertical dispersion particularly at high frequencies. This may or may not be a good thing depending on your application.

I wonder if they are the Yamaha C115VA model, this particular speaker has fly points ready for rigging. Honestly why are they suspended like that? Are they used for monitors? LOL

Yamaha makes a flyable Club series but these aren't them. Not cool. Sadly I've seen this frequently.

Hi Folks,

Thanks for all the comments.
Yep, a V-nose is good for the aerodynamics.
Art, a 110# bump up in cargo capacity looks good to me    : -)
And near Asheville there are plenty of steep hills.

A few years ago there was a composite company making some really light trailers.
They made one that was about 5x5x8' and something like 610#.
I can't find their website.

A little more info, am looking for a trailer around this size:

except with an aluminum frame, and with the wheels flush with the sides.
I'm ok getting equipment in and out of my pickup with a 3'6" height, and 4'6" would be even better!

Thanks and good health,  Weogo

Just a quick FWIW, I'm quite into home HiFi and wouldn't use a ribbon. They really suffer towards the bottom of the tweeter range, to a point where a 1" dome tweeter is preferable for 2kHz-20kHz use.

At this point, I'd argue ribbons are mostly a marketing device, unless for some reason you absolutely have to have a HF response up to 50kHz, to the detriment of things happening lower down in the range.

What it is:

A very thin sheet of aluminum, or other lightweight material suspended by two conductors, one + and one -. The element is suspended between two magnetic poles one North and one South. The element faces outward and the magnets flank the left and right of the element. When a current is placed across the element it energizes within the magnetic field created by the surrounding magnets.

The very light mass of the element lends them to very accurate sound and detail but do have limitations. The low mass element can't move very far or it will rip off of the conductors, can strike the magnets or tear and rip because of the excessive movement. Furthermore, the element is very small in comparison to say a conventional 18" subwoofer and simply can't move the same amount of air, so it is very inefficient at lower frequencies.

Ribbon drivers have seen a comeback in recent years with a few companies employing them for LA and PS units. It's not that they can't get so loud, but more what it takes to allow them to get that loud without sacrificing the benefits of the driver type. In low SPL situations where accuracy and detail is paramount, I would put my money on a Ribbon driver any day. Because of their size and low mass, they do a very good job at HF media reproduction.

Sorry misspelled it`s indeed the IG4T   !!! a super box and lightweight to ,

I agree it's a great box but is it loud enough for to use for a rock band type application as Debbie has?  I know it can keep up for wedding and corporate levels.

It isn’t clear to me what you are trying to achieve.
You have made many posts in regard to the great sound quality you have with your JBL and Yamaha speakers.
Are you looking for:
Even better sound quality ?
Different dispersion ?
More spl ?

What were you hoping to gain by replacing the DSR with DZR?

Well that was my initial thought. Since then, it has become clear that the DZR won't get me much of an upgrade over the DSR if any at all, so the suggestion is that I reduce the amount of boxes I have for better sounding pro level boxes but less of them.
This of course is a slightly different road to the initial one and now I have other things to consider like: whether spending -as Scott put- it 'exponentially more money' will get me enough of an improvement over what I already have and whether in my arena it will even matter.
I also like the scalability of what I have right now so that is also a consideration.
So I am simply exploring my options.
Would I like more SPL ?- yes I would but not sure it makes sense given the cost.

Lots to consider but I already own a nice PA and yes I am very happy with it for the most part. It never hurts to explore ones options and there is no better place than this forum to do that.....

EON610 - was $400 now $300
EON612 - was $450 now $350
EON615 - was $500 now $400
Looks like pricematching EV ZLXp. Honestly this is what they should have priced them in the beginning.

I've owned 5' long ribbon drivers in my home (Magnapan MG3s), and heard Decas and others.  Fantastic sound quality. 

A guy introduced me to his Magnapans by playing Lou Reed's "Walk on the Wild Side".  The stereo field imagery was amazing, when the vocals went from wide and wet to center and dry.  And that sax solo!
