DIY Guys... This is Making Me Crazy!

Open Baffle Basics:
Linkwitz Orion Video:

[snomofilms]

I built myself a pair of NX Oticas. Have upgraded electronics progressively over the last year or so. Now have over $50k in gear upstream of these speakers. Every upgrade upstream, these speakers just get better. Truly end game.

It would be great if you could do a video on what stats for a driver are ideally suitable for open-baffle use, Such as cone weight, QTs and so on and why.

Thanks Danny, been in this hobby a long time but I always learn something from your videos

[kevindillinger]

WOW when are we going to get the little NX. That looks like a fun speaker

Hi Danny I’m in that FB group too and I keep advising those guys to look at yr videos especially the one where you describe the process for determining the optimal side wing size… It’s incredible the weird designs people cone up with rather than take a fully developed design and build that themselves - but they’d rather re-invent the wheel ..

Excellent video as I have also noticed the very wide baffle speakers many are building. Thank you for posting Danny!

LGK's in an open baffle design! Mouthwatering idea. Can LGKs in a line source array be far behind?

[joncitizen]

Very thankful for the information you share with us Danny. I'm keen to experiment with these ideas now, but ultimately I want to try out one of your kits.

Hi Danny,
I'm an architect, located in Cologne/ Germany and since 1975 I became very curious about roomdesign and sound quality.
And for the last month I'm helping a friend to check the possibilities with a new material, for me. It's a foam of ceramic with incredible specs, especially for acoustic questions. It's the best sound absorbing material I ever tested. The combination of thin membranecells with the strength of ceramic builds up an unique absorber from very low frequencies to 20k and above.

As I saw your video this morning, I immediately thought, that the open baffle concept and with the wings, must be tested with this new material. The possibilities are countless, even for all the acoustic staff as absorbers to optimise a room, walls and so on.

Later I will send you an email with some test sheets and some links.

Maybe you'll get infected as I am right now.

Greetings

Stubby or Stefan

This was a great video. I first heard about the wings of open baffle design on the Betsy Driver page which I think condensed a thread by Dan Mason from AudioCircle. I appreciate you sharing the "secrets" that so many people miss when doing DIY. I liked the video and would request a follow-up video based on responses.

When people first get into high-end audio, they focus on the sound. Once they figure that out, they realize the sound stage is the end game.

That reminds me. I had a pair of Wharfdale SFB3's in the late 60's and they produced a lovely warm and very spacial sound. (Martin from the UK)

You are right with the Linkwitz LX521 fall off of the lower frequencies. Linkwitz actively made use of this fall-off by 6 dB/oct. As this fall-off is linear, it is perfect to use the characteristic and counterbalance this with opposite 6 dB/oct filters using active filtering and dedicated amplifiers per speaker.: The only disadvantage is the dedicated amplifiers which require quite some power. But he went further: for each speaker, he used its specific fall-off characteristic, and combined these in a 4-way configuration, whereby the spacial acoustic profile stays constant going from subwoofer to mid-low to mid-high and tweeter. The mid-high goes from 1000 to 7000 Hz, covering the vocal range by one speaker without overlap. As combination: extremely clean. The shape of the LX 521 contribute to the spacial acoustic profile, and broadens the transition area from the -6db/Oct to the horizontal characteristic. I have built the LX 521s using the original spec Seas drivers. They sound phenomenal!

This is why I was so impressed that Wilson Audio made their speaker enclosures taper toward the top. Big box for the woofers, fine, but the mid and tweeter should be in an enclosure that tappers. This has the added benefit of breaking up standing waves within the enclosure if they are within an enclosure.

9:27 I made speakers with an open 5" wide range driver on top of a box and a woofer in the box. The best speakers I ever made! They have that "more transparent" sound with bass and lower med range. 😊 The cleanest med range I ever heard in a speaker. But I did a lot more to it than just having one driver in the box and one open air. 😅

Those small open baffle speakers would fit amazingly in my front room!

[DodgyBrothersEngineering]

I've got my mids suspended by chains. Yes I have maximum cancellation, but it is like the speakers almost don't exist. It is only when a particular track does the pan from one side to the other back and forth that you even know the speakers are there.

[matthewsallman]

As the owner of a pair of NX Oticas, I can only amplify what Danny says about them. They are amazing.

[Rowuk]

The edge diffraction on a large symmetrical baffle is worse not just because of the forward diffraction. The large baffle, delays the diffraction and THAT makes it easier for our brain to “hear”.

[monrosj]

Is that small open baffle you set on the table available in a kit or as a complete speaker?
