My 4x8" fullrange open baffle

[Hatti]

Hi,

I like to show you my (little different from other) open baffle project.

I make some "crazzy" tests with edge simulation software. Than I built this baffle and I can tell you: "It sounds great!"

I can enjoy rockmusik, classic and jazz without missig anything! Never hear jazz before! I hate that! With this speaker it´s ok!
Only for deep-low frequenz, like Soundtrack: Titanic it´s not usefull! Maybe, I added a Dipol-Sub for that; time will see...

Be welcome on my page:

If you have questions, feel free to ask!

Hi,

Your drivers appear to be too near the edges for optimising the point where baffle roll-off starts.

Also by wiring 2 of them as a 0.5 way you can extend bass ~ 1 octave, but 6dB lower sensitivity.

Hi!
Guess you could call them Moby

Cheers!

Hi sreten,
first it seems to be not so good, that the speakers are near to the corner of the baffles.
So, if you put the speaker in the middle of the baffle, you get a little bit deeper frequency, but you also get a 2dB peak at 450 Heart and a 2dB hole at 1000 Heart. (see on picture)
Than you have to built a network for compensation! I don’t want something like this. The form of baffle with the position of the speakers is the acoustic-eq!
I do not need any network for correction.

To make a 0,5 system: Than I don’t get what I want! I know what you mean. It cut some mid and high and it seems to be a bigger deep frequency. But not lower frequency. The speaker and the baffle can’t play under 50 Heart. It’s a mechanic problem. And it’s really only necessary, if you hear music from cine with deep low freq.
Sound’s very good, in this constellation; I take a lot of different chassis to check, witch combination works well together.
I make a lot of test with baffles and other kind of speakers: closed, with and without bassreflexion; rear loaded horns; back ventilated; and resonance box. and now I think: “this will be the one I like, for a longer time!”

The best´s so long the best, since you find some better thinks!

@ peterbrorsen: moby? you mean moby, the big fish?

Have a good day, Hatti

Hi,

is there anyone, how make this baffle-form-equalisation, like me?

Hello Hatti,

do you have a measurement and an impedanz for us?

[Hatti]

Hi hm!

Sorry ´bout this, but I haven´t!

I tune my system with a Test CD ! Use single frequences, pink noise, sweep and drumm-solo.

Microfone´s my ear and processor´s my head!

For me it´s not nessassary to messure it! If you want? About 160 km to me!

I´m still looking for a Test-Vinyl; to tune my phono pre...


"less is more" I agree with you!!! nice Hornspeakers on your page!

Greetings, Hatti

Hatti,

where is that "4x8" fullrange open baffle" you are talking about?
In your picture/link I only see some well proportioned lady with an oversized belly button. . You seem to prefer a darker tan with women, don`t you?

Rudolf

[Hatti]

Hi Rudolf (or mr. open baffle),

you found my ladies? Terrible with that picture links! There must be something wrong...

This is an old open baffle projekt. I think, you still know what happend...



time´s changing and good stuff replaced by better stuff cheap fullrange speaker dy1026u in Ikea-box

Good evening, Hatti
