Looks really good, Rocket. Welcome to the world of OB's.

Nice build Ronny. Very nice touch with hiding the cables. aa
Nicer than these "Pegasus Reference Xtreme" which are $55,000.

Maybe you could teach those folks something about "THE LITTLE THINGS" that make the difference.

Thanks Dave:

These are shockingly good. They sound like Stax headphones in clarity, speed, and resolution.

Hey Bob:

Are they hiring?

Ronny,

Nice work! I really like you idea for hiding the cables, which I'm already planning
to incorporate.

Now that you've jumped into a world without boxes don't think that you've reached
the end of the road. Real OB bass is even more advantageous than the free breathing
mids, so look forward to freeing your woofers as well.

One tweak idea for you: The mids look a fairly tight on the backside. You'll probably
want to try it on a test baffle first before operating on your beautiful cabs, but I think
you'll get a marked improvement from really opening up the backside of those driver
cutouts. Not only is it constraining the initial expansion of the rear wave, but it is also
creating a different loading on each side of the cone (like the driver is seeing a horn
on one side of the cone and half space on the other). I found the difference quite
audible with my FE108's, which initially had a similarly constrained backside on my OB's.

Oh man, wouldn't that be sweet

I don't know Ronny, but looking around their website, I've every indication they're in Tiawan
Ready to move?

Sorry to hear about the unemployment pal, wish I could help.

Hey CR:

How's it going?

I have lived with boxless bass for many years with my Acoustats and Maggies. I know all about it. I prefer a boxed bass as long as the box is very dead, as in the OB 5's built. I like the punch and drive.

I hear you on the mids. I wanted to open it up more but did not have a big enough monster bit to do the job. It is what it is and it is too much to change it. However, it gives me the goods.

Bod:

Not to Tiawan. Hawaii maybe.

The unemployment thing was a joke. While I do not work for anyone, I do own and operate my own small Christian record label. So instead of following someone I have the machede out blazing a different path.

Rocket_Ronny and Windchaser,

It would be very interesting having you compare the OB-5 and the B200 OBs.
I see no winner or loser in such a game.

For the OB 5: I would rather want to know why crossover to tweeter is taken at 1800 Hz rather than letting 130-16 go all the way with
the fundamentals up to 3000-3500. Or is the BG Neo 3 PDR so superior ? The bassreflex of OB-5 is extremly well built.

I have long looked at that tweeter and will be using it for some experiments next year.

Hey Scorpion:

I heard Wind Chasers B200s at my house briefly, and just quickly set up with a winged baffle.

I liked what I heard. Wind Chaser said I have not heard anything, as removing the wings opens up the sound stage tremendously. I believe it.

However, I was able to get a basic grasp on the sound of the driver, which is very good. But it is no match for the OB 5's in my opinion.

That ribbon tweeter just kills the B200 in speed, clarity, and detail.

I do not hear the crrossover at 1.8K. I like the ribbon crossed over there, rather than higher for the above mentioned reasons.

I actually had some B200's on order, in the mail, when I saw the OB 5. I knew it was for me. I liked the design, so cancelled the B200 order.

Anyone using the B200 has a very nice speaker. They make music. The OB 5 just takes it to another level.

By the way. Wind Chaser was kind enough to leave behind his winged baffles. I used the wood for the OB 5 build. Came in handy.

Rocket_Ronny,

Well, we Swedes are about to have our first Astronout ever (with Discovery) these days but you are certainly up there already.
I'll see if Danny might get around to answer my question !

We had just that very thing yesterday.

We had both the OB 5 and B200 open baffles here yesterday. There is no comparison. Apples and oranges. The OB 5 is a three way design, that doesn't have the high end roll off, and with low end extension.

We played around with the B200, with and without a sub, and with the wings folded and extended. It was a neat experience for sure. I totally get the allure of this open baffle thing, it is really cool. I'm glad I got to experience it. But again, you shouldn't compare.

Cheers

Hey Daygloworange ,

Interesting, I find the OBs a bit small but thats my observation.
For the rest: I'll accept a difference if many people themselves
report their individual findings for OB-5 dominance.

I do not really get to know your preference.

Please do answer these questions:

What's not to the best with the B200 ?

What's the real benifits with the OB-5s ?

/Erling

scorpion · « **Reply #12 on:** 27 Nov 2006, 10:20 pm »

Hey Daygloworange ,

I do not think that OB-5 baffle width is anywhere near the optimum
What will you do about this ?

So much more questions to ask to you !

What's not to the best with the B200 ?

IMO, you can't compare the B200 and OB 5. They're different animals. The OB 5 is a 3 way with 5 drivers. 4 of them are 5 1/4" mid bass, and the Neo 3 for mids and highs. The Neo 3 doesn't roll off.
The B 200 is an 8" driver, it can't possibly reproduce highs the same.

Quote

What's the real benifits with the OB-5s ?

It's a three way. Open baffle in the lower mids, and the low cross over point in the Neo 3, you don't hear the crossover point. You would not think it's crossed over there.

Quote

I do not think that OB-5 baffle width is anywhere near the optimum
What will you do about this ?

I think you're using open baffle thinking. For imaging, a narrow baffle is desirable.

Quote

What will you do about this ?

Nothing needs to be done about this. The speaker is already optimized. Baffle step compensation is already worked into the crossover network. It has argueably, the best components, amazingly rigid cabinet design and damping, and a well designed network. The best one could ask for. After that, it boils down to personal preference.

Cheers

Hey Daygloworange ,

Very good answers to some good questions..

Lets keep it this way. I still hope that Danny will answer my question about the crossover ?

Hey Scorpion:

Are you calling me a SPACE-COWBOY?

What was your first clue.

scorpion · « **Reply #16 on:** 28 Nov 2006, 05:28 pm »

I'll let Rocket_Ronny stay clear in the free space where he certainly will enjoy himself and possibly others that come by.

But I do want to rise the question about the baffle width once more. If it is like you say Daygloworange, that Baffle step correction is included, I have no further questions............. Otherwise I think there might be a problem !

Yes, I think OB !

I'm not quite sure what you meant by that, but, this being a clean sheet of paper design, if there was a benefit to be had by having a wider baffle, it would have been designed that way.

What positive effect do you feel widening the baffle on the OB 5 would achieve?

Cheers

Rocket_Ronny · « **Reply #18 on:** 28 Nov 2006, 06:31 pm »

I think Scorpion is talking about the B200 baffles.

But then again, he has be baffled.

That's the best that I can see from out here. Although you should see the earth. Absolutely beautiful, as if it was designed to be there.

Interesting - are those MarkC's open baffles? Did anyone play around with that balancing circuit etc?

Sorry I could not make it out that day, perhaps the next one, looks like fun was had!
