At this point this is this is a high level question / discussion to see if folks are interested in something like this.

All I can see it would be pretty comparable to other high end 410s.

The devil is in the details

Ok, internal chambers filled with Helium to provide bouyancy- now there is an idea! It would still have more than 25 lbs of intertia, but would only weigh 25 lbs...

You'd have 4x10 tweeter box if it was filled with helium.

Maybe something with magno-lift - oh I see unobtanium was already mentioned

In my view, the OP is directed at those who would be interested in a 2x10 or 4x10.

On the other hand, the responses to this post might be helpful to the cab designer, as a preview of what kinds of questions and comments to expect.

Again I don't want to speak out of school at this point, but I remember hearing something alone the lines of %100 stability. So right now I'm just taking a positive assumption.

From my experience with light cabs, I dont think its possible to stop them from jumping when giving them the required wattage... no matter how much bracing, how stiff etc. The only thing you can do is put a 40LB rack (etc) on top of it.

Perhaps ratchet lock-down systems set up on every stage, ready for us.

[mjac28]

in answer to your question sir "yes"

[testing1two]

"...the coolness of the 25lb 4x10 cab was diminished somewhat by the sandbags needed to stabilize it."

[::::BASSIST::::]

Just carry a small piece of carpet to place under the cab. I believe the would stop the jumping. One time I was using my old LDS 15/6 (44LBS) and I was pumping about 800-1000w into it at a large club gig. The thing jumped every time I played a low note. I watched in horror as it slowly moved its way to the back end of the stage with a 2 ft drop off. Luckily, the song ended before it reached the stage but I was stressed as I had about 500 people watching me. Funny now, but not so at the time. True story.

I put a large monitor on top of it and problem solved.

To answer the OP's questions, I'd be interested, but only if they sounded really good, had high power handling, were very durable, and were competitively priced. The weight would get my interest, but it wouldn't get me so excited that I would buy it regardless of the other factors.

I like light weight gear, but there's a point where it stops making a difference. What are the lightest 2x10s on the market now? 30lbs? That's pretty easy to carry with one hand, so I'm not sure I care if someone can cut that down to 16 pounds.

I've had both Berg and Epi 410's. They're certainly different flavors from each other, but I certainly found either to be eminently giggable.
I'd be more interested in two 210's stacked vertical than a 410, simply because I've grown very used to both having a taller rig closer to my ears for better personal monitoring, and, I think that trhows cleaner out into a room.

So: interested?
Sure, I'm always interested in something that makes my gig easier/better.

Show me/tell me more!

[bobcruz]

I voted "no." Teaser thread with insufficient info = big yawn from me.

[CL400Peavey]

I think its interesting that my comment automatically caused others to think I was referring to any specific design. From an engineering standpoint two 115's or 210's stacked vertically is a better design. As far as questioning neo speakers.... Get real. There are good speakers and bad, the material their magnets are made of is of little consequence.

[Tactician]

Well the Alphalite 6" weighs in just over two pounds. So rather like the Phil Jones set up you could build a pretty cool 4x6 cab that would handle quite a lot of power - I 'd have to do the numbers to check the point where it breaks up - I suspect somewhere around 150 watts. But the cab would be the problem - to make one at less than 16 lbs. To do this I'd be restricted to a straight ported box made from 1/2 ply and using expanding glue joints - no corner braces. Probably come in underr 25 lbs - but as soon as you get into anything clever with folded horns, scoops, and W cabs you'll overstep the weight limit.

Anyone tried a 4x6 set up yet? That's got to look like a cute little cab.

[darkstorm]

Most bass and pa speaker cabs are poorly braced to begin with imo. Doing cabs at so low a weight is gonna be near impossible. Maybe some sort of tonko toy plastic it you could get it to hold needed screws well. With it mainly glued together. But palstic cabs Ive heard even when stuffed with acosutic insulation where subpar sounding compared to other cabs. Lightest good cabs Ive played where eden nemesis 2x10 and 1x15 ext cabs. Around 34 pds and 30 pds respectively. Lightweight sturdy solid wood is best material imo. Aluminum for cab sounds horrible when Ive heard such a cab.

[T-Bird]

Hi.

I wouldn't be interested.

OTOH to clarify that a bit, I would be interested if the price was low enough, but it wouldn't be, unless shoeless 3rd world children were doing the CF work.

Building a cab that behaves like that is super easy. Anyone who's built cabs have probably succeeded in doing so.
Building one that is both light-weight (or medium light) and doesn't waste energy on flexing the panels, that is HARD.

Why 10's?

Seems to me that the stated parameters are of significant benefit in the cab weight element -and the restriction to 10" drivers [particularly to a 4 element square layout] is a silly way to present the concept. This point is illustrated in post #5 herein:

One of the lightest 10's I can find weighs 3.5 pounds, so 14 for 4 of them. How do you propose to build a properly supported cab around them that only weighs 11 pounds?

If the design succeeds in advancing a practical means of achieving an affordable cab large enough for four 10" drivers - including finish and hardware - that comes in under 11 lbs. - then the designer is really onto to something.

Insisting that this revolutionary cab design must only be used with 10" drivers is unfortunate. That said, if the cab construction method can yield a practical unit at the stated weight [including cost addition] it will soon be adopted by others who do not have this mental limitation.

Thank You Jim, Alan, mjac28 (and several others)
For answering the OP.

Not sure where to begin so I just will, and I will attempt not to sound to random...Forgive me it was a late gig last night and only on my first cup of coffee.

Hello fellow players I'm just going to do this in bullet format to make it a little simpler for my slow mind this morning.

- Number 1 this post was more less put out there to see if folks would be interested in such cabinets.

- I never created this thread to start design debates with folks. It appears like there is slight degree of animosity in some of the posts.

- Details, details, details...Well, ok I don't know them all. However (I cannot believe I'm about to explain this and I'm not doing this in a snarky way, yet polity) I cannot mention certain details. Realize the players involved in this project design/build for a living (you know pay the mortgage, put food on the table, ect) If you are looking for design sharing then there are other DIY posts and forums that would better serve You.

- The concept of the design mentioned in my original post was the need to cater to working/professional musicians and meant to be positive thing. Not a dick wagging 'look how light I can get MY cabinet...aren't I great' Pleaseee...

Aloha from Beantown

[basswave]

Just to add.
Nobody will even see this if does not work.
Beside myself there are 2 other heavily gigging players that will be putting it through its paces.

That means it has to sound great first and foremost, take normal road abuse and be functional in a variety of situations.

I am the designer, and have been working on prototypes for a while. No helium involved I'll have the some informal test results done by the end of the week. The first 210 will be available for test drives November 3d.
