Default Visaton B200+Eminence Beta 15=OB!

Hi,

After a lot of contemplation and buggin' people with various questions, a lot of blah blah...
Finally I did it.

It is basically a copy of Visaton No-Box Open Baffle. Just using an Eminence Beta 15 instead of Visaton BGS40.

I still can not comment on the sound, I am still connecting the wires...

There are no binding posts, I will solder the speaker cables (0.95 mm magnet wire) directly to speaker terminals. It is a biamped system.

Visaton B200 is driven by Pass Diy Zen V9 without feedback. Eminence is driven (temporarily) by a modified LM3886 amp. Preamplifier is a 6922 based tube buffer (Jfet CCS-ed cathode follower). Crossover: Visaton-180 Hz first order (or, just a cap). For the woofers, I am going to use a LR 4th order 110 Hz lowpass that is left from a project in the past. Gotta experiment here....

I'd like thank everyone here for motivating me to go OB route. Other people's projects (like Yunick's) have been an inspiration. Special thanks goes to Choky, Martin, and Nelson.

P.s. Nelson, I've been a good boy. I did my homeworks. Can I expect that will bring me a nice present? Oh, I just hear that is far away so he won't be able to bring a tangible gift to my place. Ok, then, I would accept an intangible gift (like a schematic and/or an article), and I'd share it with everyone on Diyaudio...

I'll be interested in hearing how they sound.

I can see a couple places (besides phase plugs ) where you could likely get incremental improvements.

Thanks Dave.

First impressions: Sound is huge, but it lacks body. Like some hollow ghost through the whole room. It was with the crossovers as I described. Then I disconnect the bass speakers, and run the Visatons fullrange. Better. I like it more this way. 1st and 4th order crossovers do not integrate well. I am even thinking to try passive configuration, both 1st order...

I'll let you know how it sounds, a lot of experimentation to be done...

Regards,

Vix

Wife's comment: "So, what is next? Two big speakers on each side of the wall, and you standing in between? "

WAF passed, she likes the look and the color....

learn from Yunick's example .......
anyway - it's hard to mix 1. and 4. order .
when you must mix orders, then you can somewhat easier mix 1. and 3. , 2. and 4th ........... so these parts have phase diff of 180degs

in Yunick's case - big one is crossed at 150Hz(180?) 6db/oct with Boucherot across terminals

smaller one is crossed intentionally at 350Hz 6db/oct

I know that I'm pooooooftaaaah ............ didn't make you these plugs ..... yet ......

I am listening to Visatons only (fullrange). It sound very good! With some music there is almost no need for bass hepler!!

I'd like to see (and hear) a WMW (woofer mid woofer) open baffle speaker with these drivers and with a good passive or active x-over.
