Looks like morrow audio has a new commercial OB effort

Yea, It looks like Morrow Audio and Common Sense Audio have teamed up!
Seen those P-Audios on CommonSenses website!!!

Time to launch a website!

John,

You have some neat ideas...what are you waiting for?

Richard,
I know I'm too blunt for many of AC's circles, but they
should just be ashamed of themselves to post that thing
for sale.

Manowar,
I need to get more scientific first, as well as identify a
range of active XO solutions. Not to mention, I'm too
busy to get ideas built. I paid my construction helper
too well, so he left for the beach about 6 months ago,
and has been due back any day for months.

Hi JohninCR ~

Not to blunt for me John... call it as you see it!!!

Intelligence demands honesty ~

These forums are here so we can share our insights with each other ~

The corporate mentality has muzzled the mouth of humanity... domesticating us
into lap dogs... we were once magnificent beings capable of incredible feats of
magic... we were once alive with the mystery of what it means to be alive ~

It is not too late to claim that gift again ~

Warm Regards ~ Richard ~

Yeah, that looks about as nice as what I have built... mind you, if I could sell my panels for US$1200...

Ahem, hey this sub looks interesting, affordable, and if used with only 1 VC, would it not have a QTS of around .76?

I will email these guys for sure, a pair of these 12's would go right in my baffles...

JohninCR,

Another vote for you to put up that OB Fanatic website. From reading your helpful insights spread throughout this and other threads on AC as well as diyaudio.com, you obviously excel in your knowledge and experience regarding all things Open Baffle. Your expertise would be very welcome and helpful to those of us just getting started in the world of OB audio. It might keep you from getting so many PM's and emails... OR NOT! Between you, Dmason and barfind (Nigel), there's a wealth of OB information available some of which is contained in Dmason's great "Gravity Well ..." thread. Thanks!

-- Roy

You could propose an OB special interest circle if you wanted to...

I propose an OB Special Interest Circle.

More and more people need to know about this stuff.

I second the OB Special Interest Circle. The more fence sitters and even naysayers that can learn about this, the more it will grow. A few months ago I glanced at full range driver topics, but basically poo pooed them as "how could that sound any good?" I think that the more popular that they become, the more likley that an individual will have the opourtunity to
audition them, either at a fellow member's home or a meet,
and that will be a deciding factor. Either the individual will hear the magical potential... or not. OB's are not going to be everyone's cup of tea, but I think that a lot of audio enthusiasts will prefer them given the right opourtunity and set-up.

Vinnie seems like a really nice guy, and though I've yet
to experience any of his products or services, by all
indications they are quality at a fair price. I'm sure
he loves having this thread in the Red Wine circle, so
let's keep the discussion here for now.

I do like the idea of an OB special interest circle and while I love having all you guys stop over to the RWA circle for some "darkstar action," I have no issue with moving the entire thread over to a new circle (I can do this as the admin for this circle). I believe that I can even "mirror" it

I totally agree, markC. They are without a doubt MY cup o' tea. I can't get enough of my OB sound. I can only see things getting even better if/when a "special green" OB driver hits the OB scene!

And the Gravity Well is almost at 1000 replies!

markC · « **Reply #910 on:** 10 Aug 2006, 03:10 am »

Yes, Vinnie, special green and my preference-special black.

Dmason · « **Reply #911 on:** 10 Aug 2006, 03:14 am »

Yes, we can all look forward to the forthcoming "Kona" and "Kashmiri" alignments.

and a special distillation of the science as it is known, with John of the Jungle pushing back the envelope.

Hey this may sound crazy, but has anyone experimented w/ speakers meant for guitar amps? Before I ever heard about this OB stuff, I thought the Celestion 12" speaker in my open back guitar amp cabinet seemed to be able to reproduce a pretty wide range frequency range. It got me thinking in the general direction, but never followed up w/ any test.

Dmason · « **Reply #913 on:** 10 Aug 2006, 03:59 am »

John

From the beat of the drums on my side of the Jungle, DW did indeed listen intently. Various flavors of green, and word of a true coaxial 10" which would be the jewel in the crown...add the Signature 30 and be done.

For OB "ready" guitar speakers, www.tonetubby.com which come in Mint green and Alnico flavors. The 10 looks REALLY good, and apparently Louis Chochos has some of the 12's to experiment with. Mark of Del Mar has some 10's in his Fender Bandmaster/6L6 PP, which he loves.

Dan, could I suggest then that you start a thread in Town Square? Say what you'd like it to be, restrictions, etc. i.e. would you rather full-range drivers only, or would any dipole speaker be welcomed (Orion, Phoenix, NaO etc).

I expect there would be a lot of interest either way.

By convention, the proposer volunteers to "facilitate" the circle as well.

Dmason · « **Reply #917 on:** 10 Aug 2006, 04:33 pm »

JohnR

I appreciate that, however, I would suggest that the leader here, John in CR, be the facilitator, as he is leading the class. I am but a humble student, here to bask in the glow of the revealing science of Acoustic Physics. My only other suggestion would be to limit technical recommendations to those based on actual experimentation and direct listening experience, and ban/delete the posts of theoreticians, and other OB imposters, in order to keep the text "clean," and in the context of the real. Limit the content to question, answer, experimentation, and "scientific method." A "stream," in other words.

If John in CR would rather not, then I would be happy to Facilitate the new Thread, if no one had any objections.

JohninCR · « **Reply #918 on:** 10 Aug 2006, 05:38 pm »

I'm not the leader, I just am strongly opinionated
and have a big mouth.

To me the status quo is fine. Vinnie put up with the
thread wandering far and wide, so I think he should
retain the benefit of having this 100 page monster
in his circle. I'd think it must drive him some business.
The community won't benefit from breaking it up or
starting a new thread.

What needs to be done is extract the pertinent info
and essentially create a resource of basic information
attached to a multi-segment forum. The segments
would range from single drivers to multiways to deep
bass, as well as electronic and others methods used
to shape response. This is no small undertaking, and
I believe that doing anything less will result in another
monster OB thread for people to trudge through.

I've used both guitar speakers and the similar drivers found in old open backed radios and console stereos. They can work well but tend to have issues that need to be delt with. Many of them have a nasty resonance somewhere between 2 kHz and 5 kHz that will need to be tamed (notch filter works) then roll off fast above that, and few have much bass below 100 Hz. They can make a nice and efficient extended midrange, though. Just add a tweeter and bass augmenter/subwoofer and you're ready to go.
