My ugly A.. salad bowl OB's..

JandG · 16th February 2008, 07:56 PM

I thought to try this & did. I am very happy with results after bumping to the tweeter back into alighnment w/ other drivers. Smooth, detailed & still retain the OB magic. Just more refined alot better imaging. Stage is fairly much stuck to between speakers, but it is very pin point. The salad bowl's are rubberwood. I thought it would all be shouty, is not the case. I use a 600hz effective 3rd on the mca15rcy & 4mh on 12" alnico fr & just a 2uf cap on the 3" fr tweeter. The 3" were ripped from a pair of highend cherry JVC mini units. 300B PP w/ 26 DHT pre leading the way. Dual powered subs set at 60hz 4th active. All seems to integrate very nicely. Why doess it not shout..? This was just a experiment.

To be brutally frank I don't care for the looks.
Maybe if the bowls were faced the other way around.
In the end the sound is what counts of course.

I love it!

Lot's of other goodies there too.

Yep, ........There ugly as as a mofo...*s*. I did however learn alot on how OB reacts to such things. Turning them around would not work. unless you ment mouted on back of baffle. That would be intresting also. I am sure the percieved stage would move backwards, as some times I put very small lenghts of sono tube, 3" max around the back of driver to delay OB effect & sharpen imaging & move stage back. I got alot of pretty commercial speakers collecting dust in the dark..*s*

Joe,

How does the "Coral CR12A" sound in the lowrider position? Any guess as to that driver's Fs? Have you measured it?

Mind if I ask where you sourced the bowls? They appear to be scarce in my area.

JandG · 17th February 2008, 12:46 AM

Our local Target store had them. i seen em while getting dog food & swooped em up..
Not sure about the Fs of the 12ae. I will pull the 12ae when I get replacements for that spot & lower the 12 or 15 to floor. The 12ae really should be used for a single fullrange for someone. I am going TT on my next build. I think I will keep this basic Salad Bowl gig going though, it does alot of things well. The 12ae are to rare to keep in that spot.
