I’ll just leave his pic here. Let’s just say the churchhouse was rocking lol.

NIC.. I have found eth "B" contour can help fix a Boomy stage too.. And also sort of mimic a sealed type cab .. The MG800 is not a one trick pony...
Sturdy little sucker too..

Just to push this point a little further, if you are having some sub LF rumble due to room or stage acoustics, the Contour B is a great option to tame that because this Contour does attenuate those ultra lows and provides a nice 200 HZ bump. Perhaps a setting of 11 - 2 oclock. Even if you still want a little more "modern" shape, you can also bring back some more top end and cut some mids (700 Hz) in the EQ to bring ba'ck a nice spank to the tone.

Interested to know the concept for the bass array. Specifically, when some bassists choose to turn off their tweeters, the choice was made to put 3 tweeters in an amp with a single 12” speaker.

I love my Shuttle 6.2. Just interested. Not a challenge.

Thanks Jeff! I have gigged the MG800 with single BA12-3 quite a bit since last year using my Stingray until I got my Sadowsky in the fall. With my Ray I was heavier on the contour and used the "B" a lot more, especially for the older 70's rock tunes. I've written about this before but as soon as I switched to the Sadowsky it was a match made in heaven. Just basically plugged in and turned on the amp and had a great evening.
The boomy room was longer and narrow with a really high ceiling. I was using a single SLT12-3. I just dialed back on the bass EQ very subtly. Didn't think to mention it here but I'm glad I did.

BTW, the combination of the MG800 with a BA12-3 and SLT12-3 is absolutely incredible! I have a loud gig in a big room tomorrow night and cannot wait to loose the beast!

Game changer for me. My cab before my BA12-3 was an older Dave Eden 410XLT. For me it was a great cab for years and the only reason I looked at Genzler at the time was an issue with lugging the 410. The BA is so much warmer and the sound projection is superior. You can stand beside/in front/behind and still get the same sound. The paper cones are very warm yet the sound coverage is much better. I find the horn on my Eden harsh and honkey now after playing through the BA12-3.

They turn them off because the highs are harsh. With these BA speakers they are not. The crossover is seamless and the array gives dispersion without having to resort to a horn.

Hey @Basstards I think you're missing the concept. There are no tweeters in this cab design. Those are 3" paper cone soeakers for all the mids and highs.
Very different design all the way around.

I see. So no “tweeters” per se. But they are very small drivers. What’s the frequency range of the 3” drivers? And considering we play low frequencies, what led to the choice to add 4 of them?

Again, not trying to be a challenge. Purely interest and understanding. I’m sure you’ve forgotten more about cab design then I’d ever dream of understanding.

 

[mwbonsall]

Just a guess, because they sound great.

I'm fairly sure this is the driver in question - Invalid Link Removed

Putting 4 of them in that arrangement gives you the same advantages of a line array - increased horizontal dispersion. So the mids and highs are not beamed straight in front and the bass sound is more consistent as one moves around the room.

The cabs are very balanced and smooth through the entire frequency range.

That’s a little 10-2 peeking out behind the upright.

The timing of the "boomy" discussion couldn't have been any better. Hit my second boomy last night. Weird shape layout to the club. Fought the boom for the first 3 songs, turned around hit the "B" contour to 11 o'clock and just slightly pulled the mids out. Ka-bam! Back in business. Finished the set to great effect, went to the bar at the back for a beverage and had a bass player strike up a conversation. He knew the room well and had seen lots of bands struggle with the sound due to the acoustics of the room. He complimented me on my sound, wanted to know what 410 I was using, shocked at only playing out of my two BA12-3 cabs, and asked me how I fixed the boom after the third song. Came up to watch the 2nd set and had a good inspection of the Genzler stack at the next break.
That was fun! Created another Genzler fan.

Glad this worked out for you in a challenging room.

@Basstards, certainty we thank you for your interest in the Bass Array design.
The basic principal is that we allow the "right sized" speakers do what they di most efficiently.
The 12" reproduces all the LF and low mids up to approx 800 Hz. The line array of the 3" speakers rollin in around this frequency and extend all the way to about 16K Hz. Because we're using these 3" drivers in a line array they expand the horizontal dispersion to approx 120 degrees, much broader than a conventional design. And because we roll of the upper mids and highs from the 12" we reduce a lot of the beaminess off the dust cap of this woofer.
It is a seamless transition of frequencies with this design.
The clarity that these small drivers produce is being proven by players on clib stages around the world.
I hope this is helpful info about this design.

I agree 100%,, "B" fixed the mess that i had last week without twisting knobs to find a frequency and then ducking it... 1,2,3 it done in a second now that i know what it is capable of.

Isn’t that the new 4x10...

 

[spiritbass]

I wonder what that Genzler cab is to the right of the Ba12-3 stack?
