Vertical cab stacking---the only way to play

[billfitzmaurice]

Bill as long as you're answering questions...I have the Music Man2x12 and was wondering if I'd be better off laying the darn thing on its side w/ that port thingie verticle instead of on the bottom?

Yes.

Need help!

I have a home-made 2X10 bass cab. It looks like this:

So, how would you vertical stack it? Is it possible?

 

[Toffa]

I would say... turn it counterclockwise!

Nope. Diagonal mounting doesn't allow for it.

Nope. Diagonal mounting doesn't allow for it.

So there will be no change is sound if I turn it counterclockwise?

No. Replace the baffle and mount the woofers vertically.

No. Replace the baffle and mount the woofers vertically.

Bill, where would you put the tweeter?

Will something like this work? Or is there a better way?

Sorry for the crappy drawing

Also, is diagonal really that bad? I thought that it would be better than conventional horizontal design.

It would be best to have the tweeter on the same vertical line as the woofers, but if you can't put it at the top of the cab as close to the adjacent woofer as possible, Should you ever build another for stacking place its tweeter on the same vertical plane but at the bottom of the cab, so that when stacked the two tweeters will be as close to each other as possible.

Diagonal is better than horizontal, not as good as vertical.

Yes.

Thanks. Will give it a try next chance I get.

Hi Bill
If you wouldn't mind commenting on my rigs in regards to the speaker/driver compliment and arrangement. I like them well enough, but after reading this 'vertical' thread I wonder how the stacks or indivdual cabs' design "stack up" ?

Thanks if you care to comment. Just for my own info. I've attached a pictures
The 4ohm 212 3-way has a tweet and 6" mid
The 4ohm 115 has a tweet.
The 8ohm 112 3-way has a tweet and 5.5" mid.

Thanks very much

I stack a pair of eden 2x10's vertically and it is great! I have been doing this with various cabs for a long time. It gets the sound up in the air, you still have coupling to the floor for low end and it takes up alot less space on a stage.

Having a midrange greatly reduces the need for vertical woofers, and if crossed over low enough eleminates that need entirely, so your woofers are not a concern. The way pictured I'd turn the tweeter in the 15 off, it's too far away from that of the upper cab and they're not on the same vertical axis. In the second shot the 1x12 should be placed upside down so that the mids/tweeters of the two cabs are on the same vertical. That also puts the tweeters in a M-T-T-M alignment, which improves vertical pattern control.

Thank you very much for your highly respected opinion Bill.
I do turn off the tweet on the 115 when using it with the 212.
The 112 should easily flip over... guess the horizontal port doesn't matter being on top then.

My $0.02 (of course, I know nothing compared to Bill F.), for the 1x12 + 2x12, if you don't want to flip the top cab, you can try turning the 2x12 midrange and tweeter control all the way down and possibly increasing the settings on the 1x12 midrange and tweeter (of course, the settings on the 1x12 would be to your own preferences -- if you already cut the HF on both units, then just set the upper midrange and tweeter to whatever sounds best to you -- as long as you turn the lower cab's midrange and tweeter all the way down, you should avoid multi-driver interference).

That could be done, but then he wouldn't have the vertical pattern control of the M-T-T-M, which would make for much more focused mids and highs, and he'd lose 6dB of mid and HF output.

Thanks Guyz
So what about the horizontal port being all the way on top with the cab flipped over ?

It'll make no difference.

Correct.

I was just thinking that some people (but definitely not all) prefer the higher frequencies closer to ear level (and also that some of that 6dB loss could be added back by adjusting the attenuators on the top cab's mid and tweet controls -- if so desired).

Bill, how low is low enough? Also, is the "low enough" crossover point different for cabs with 12" vs 15" woofers?
