>>> 5 x 12" focused OB arrays (unknown driver)

Not sure but they might be Eminence Beta 12LTA or the similar Fane?

unkwown driver

These drivers are C 1230 ACR see thread Stereophonic Sound Of a Single Loudspeaker post 314

thanks.
"concave vs convex (a waste of time and too wide driver inter spacing). Better to go directly to concave. "

I had a 9x4" concave.

Sorry it is not OB, but this is my next project 4 x 12".

Another Desktop OB

I recently completed a pair of small open baffle speakers for my desk at the office. The baffles are 7" wide with 3.5" wings on either side and are 10.75" tall. Drivers are MarkAudio Alpair 7p. Added a little baffle step compensation between my music source and amp to bring the mids and highs down, which made it easier to EQ the bass to a matching level. Bass is now adequate at the 1-2 foot listening distance. Still a work in progress to get the frequency response nice and flat, but I am getting closer...

needtubes nice work for not OB speakers .
Have you tryed with a 10R in series to rise the Qts ?
tube amp work too

 

[needtubes]

Thanks!

I haven't tried to insert any series resistance, but may try that soon. Seems that they lost a bit of liveliness and clarity after inserting the BSC filter.

The speakers are currently powered by a ~1W tube amp using 6C45's.

 

[norman bates]

neat.

I had 2 W3-871s on an open baffle (maybe 6" between centers).

Sounded great at about a foot, especially on Q-sound recordings like Roger Waters "Amused to Death".

if I remember well tube amp rise the qes for about 30% qts,the resistor trick is for ss amp

really nice minimalist system please tell more about the sound !
you can simulate con xlbaffle

For those interested in DSP based active dipole speaker systems, this is new: www.iconoaudio.com

First appeared last June at T.H.E. Show in Newport, California.

I have been working on trying to get a balanced full-range sound for about a week now and am closer... The system is as follows: Fiio X3 portable music player loaded with high resolution FLAC (also provides some equalization of bass frequencies) into a baffle step compensation network (currently ~12dB cut centered at 200Hz, I believe, which is quite low but offers the best sound so far) which then feeds into my 6C45 spud amplifier.

They sound quite nice. With my equalization choices, the bass is present although still a little weak. The OBs sound best on simple music like jazz, in which case the bass line can be heard more clearly. Imaging is fantastic on good recordings - the speakers really do 'disappear' when playing. Overall, they make quite nice desk speakers for my office.

OB XO Test Bed

I made this OB as a quick way to test novel active crossovers (B&O Hole Filler, etc). It turns out to also sound very nice. 2x Beta 12Cx, 2x TG9FD10-8, DC28F-8. miniDSP and 4 channels of TPA3116D2 class D amps.

That Icono looks really cool!

My filter who is more coherent with even frequency response. I made a little midbass bump because i like it 🙂

Lowther PM6A:
12 dB high pass: 33uF serie - 1,8 mH parallell
Serie notch: 3,3 uF / 0,1 mH / 27 ohm

Tone Tubby:
12 dB low pass: 5,6 mH serie - 100 uF paralell

With and without notch. It is absolutely neccesary.

I am going to try your filter net work.
I have been using my TAOB with John's XO for a couple years now, but have been wanting to try with notch.
Thanks for sharing.🙂

Big Green Open Baffle ; 2x 15 & Lowther DX3.
These were old doors !!
Passieve x-over 12/6. I call this a ZEN x-over. Based on the sine-cap x-over by Sonus Faber Extrema (old one).
This was a wednesday afternoon project ; had the units in the house.
The x-over took longer!!
2 day ago we tested the AER MK1 in this setup. Some minimal adjustments to the x-over (listenable after an hour or so).

Hi Leon,

That Green looks Mean... and I like all the other stuff on the picture..

What drivers did you use for the 15"/ I can make out "Sphynx" but which type?.

[Leonidas]

sp w15 bp ; I had 2 sets !!

 

[Leonidas]

some measurements ; I do like some more bass!!

Do you have an other driver in mind?
