Melon Head's State of the "DUMB" Open Baffle Design

[Antoinel]

Here is the open baffle test chassis. I can locate the driver anywhere up and down the baffle, and cover up the holes that I am not using. I will use cardboard initially to add wings or increase the height of the baffle. Probably add piano hinges later and use wood for the wings. Anyway just getting warmed up.

Melon Head: Your wood-working ability is highly impressive.

You know how easily tempted by that remark - but we have already done damage to Chris and out of consideration of not having to send him off to mental vision re-hab I'm gonna pass on this one.

This reminds me of a South Park episode

Frequency response.

 

[Melon Head]

Ported Open Baffle. LOL

Just out of curiosity, I thought I should measure it with the bottom cut out exposed.
Doing so extends the bass response another 100Hz before it starts to drop off

EDIT: Later I might see what happens if intentionaly put in a port tube

1.5 Way

It's probably no secret .5 ways are my favourite

ginormous BR. Will you stop messing with those Seas and get on to the good stuff.

 

[Melon Head]

Yeah, yeah.
Except I am going to bed now.

 

[Chaz H]

So you do sleep!

 

[c2cthomas]

Yeah, yeah.

So you do sleep!

That iz not what he said........

 

[Melon Head]

ginormous BR.

Just a rough calculation makes it about 3000000 Litres. Haha

I don't get the pictures.

Can you show it from behind ?

Is the top driver open baffle and the bottom driver sealed or ported ?

Have you seen the Tekton Design 4.5ob or the 6.5ob ?

[Melon Head]

It is open baffle with wings
I haven't seen the tekton design,but I will check it out

 

[buzzforb]

Why not just do U baffle for the woofer amd OB for the FR. Same thing without the interference cause to FR. I bet imaging and soundstage would improve.

Here it is from behind

Mellon Head,

I don't want to rain on the parade, but the best way to make this OB work is to get some 12 cheap 8" bass drivers . Then, you could leave that Seas on top, and build a Slot-loaded bass support with 2x3 8" bass drivers...

That would be too orthodox. I like to try dumb ideas, espescially my dumb ideas. Haha.

Yeah, yeah. That makes too much sense. I am only doing this purely to try ideas and to confuse people. In the end I will probably throw the Seas in the bin. The Seas FR drivers don't excite me at all.

Having said that i do intend on building the slot loaded baffle but with 4 x 10 per speaker

Now we are getting somewhere

 

[Melon Head]

Yeah. Maybe set them on fire first. Haha

 

[buzzforb]

I did that over the weekend to a couple of things.
