anybody using four 1x15" cabinets stacked vertically as their main rig?

ZZ Top got ripped off of all their trucks full of gear somewhere in 82-83, when I was in Memphis. They cancelled Memphis, then a week or so later said it was back on, because all the shops in town loaned them all they could. I remember not noticing it was really quiet, but you could speak to the fella next to you without cupping your hands and yelling in your ear. What I did notice right off the bat was the great bass sound, both drums and bass guitar. Best sounding concert I went to outside small, well setup collage concert halls. All my buddies noticed it too. We were from row as always because we waited overnight at the 24 hr beer serving pool hall that was the only outlet for the front row block the Navy reserved for us. We saw everyone that came through there, twice a month plus additional concerts at other venues. Met Joe Walsh and he played I.L.B.T.'s for the first time I heard it. Nice fella, very interested in us, our shaved heads and what we were getting trained for in the Navy. That event, also really good sounding, on mud island, not so loud, not much seating and unannounced free concert.

What, may I ask, is a "drone set"?

Its one of those things other than rock gigs.
probably the defining band of this rather odd subgenre:



not even really "music" as much as a sort of sonic sculpture, with air-molecule-frying volume as a key component. my guess is there's no drummer or singer because it would be physically impossible to mic or hear them.

i also suspect these guys rock the monk robes to hide navy carrier flight deck-style ear muffs.

Ummm, ok.

I guess this leads to more questions like tunings and intervals and harmony and counterpoint and phrasing and such? Is such music played in particular keys, is everybody tuned the same?

This is one genre that I have not been exposed to, after almost 40 years in the music business.

Never heard bagpipes?

If you want to pick up on the tune there, there are sped up versions of Sunn O))) tunes for the short of attention span:



My stuff is all in standard tuning with occasional drop D using a Hipshot. Guitarist gradually drifts out of key/tube during the set, but that isn't on purpose. The ringing open string nature kinda means stuff is mostly in E, A or D.

Edit, ASVA is an example of a drone band with drums, also Burning Witch. I particularly like ASVA's occasional use of fast twin kick drum as a texture rather than a tempo.

Well, at normal speed I did not hear bagpipes... at least not the ones I've had to work with before.

Perhaps I just don't understand this genre as well as most others? (Or I am getting old and think the younger generation's music sound like noise, not unlike our parents and grandparents thinking the same about our music).
 
With line array PA systems the sub cabs are all horizontally lined, wide apart.
So horizontal stacking can be equally efficiemt than vertical, and theoretically an 2x2 arrangement should be more efficient than a skinny stacking cause coupling of sources is more efficient (larger).

Wth a line array PA an evenly alignment of elements would not make sense.
Requirement is a cosistent SPL in the house which demands a large line which is often aligned as "J".

While the sub line cabs are aligned horizontlly wide apart (so there must be a lot of comb filter problems?), but there is no problems with horizontal stacking at the lows in the pro audio world.

Personally, on stage, I'd probably prefere a 2x215 side by side crossfiring over tall skinny stacking. Just reduce large vertical comb filter affects, with a drawback of more of horizontal comb at the high mids. But I don't prefere to stay way to off axis on stage.

The reason there is no interference problem with the subs laid horizontally is because of the frequency range they normally operate in. Typically subs are crossed over below 200Hz, often around 150Hz. Interference effects start at frequencies that correspond to a separation between cone centers that is more than one quarter of the wavelength. For 18s the minimum separation between cone centers will be about 19 inches. The frequency at which 19 inches is a quarter of the wavelength is 183Hz = ( 1160 * 12 ) / ( 19 * 4 ). This means there will not be significant interference effects below 183Hz for typical subs laid horizontally. If the separation distance is 20 inches, that frequency changes to 174Hz so with more separation the interference frequency threshold goes down. With a crossover frequency of 150Hz, the interference effects for the subs will be minimal.
 
There is interference based on cone centers AND overall array length because there are other cones farther away than the adjacent cone that also interfere.

It's not as noticeable because of all the additional LF reflections from boundaries and because the ear is more forgiving to this issue at low frequencies.

In the pro world, subs are almost always crossed over at 100Hz and lower.
 
Jack Bruce took some influence from drone bands on his last album.

What have you been listening to lately?
I've got a son who's 21, and he played me some things about a year ago. I really liked what he was listening to and I started writing. I got very influenced by a band called Om and a band called Earth, and I liked what they were doing. So I kind of got influenced by those young bands, as opposed to what I've been doing all my life, which is influencing other guys. That led me to write this song called "Drone." It's my version of the drone genre, if you like.

Bagpipes are a drone instrument, they have been around a long time in a lot of cultures, drone is an ancient form of music, also appears in local of meditative vocal forms and such. Its just electrified now.
 
Back to the original question.
It can be done.
I have never tried 4 115s.
I have had 2 215s
and
a nice 2 115 stack.
Once played through a Marshall Major 415 . :D

All unneeded these days.
All great fun, except for moving them.

I personnally wouldn't stack a pair of 215s vertically.
Sure I like the better, more even sound spread idea,
but the stages I end up on are not that solid and
getting crushed is beyond my pay grade.

If you or anyone else wants to move, stack and play on them,
it's OK with me.
I will, however, point out that if you do that in your small local
dive bar, they may not be able to hear drink orders and that
can lead to not being invited back. :laugh:

Ask me how I know.

For a variety of reasons -- needing more output & wanting to get speakers up closer to my ear, but still desiring a modular rig & recognizing the value of a stacked columnar array -- I've been entertaining the idea of getting four 1x15" cabinets and stacking them vertically.

But I haven't quite wrapped my head around the scale/proportions of such a towering inferno. Anyone use this configuration regularly? Got any pics of your rig?

Thanks.
I used to use 4 15's all the time. But vertical, I think 3 is optimal. I played through 3 12's yesterday and wOw. 3 15's would be similar. The 4 15's can be overkill depending and they can sound sweet depending. Just listen and blend the music; don't try to overpower.

Had no idea, thanks a lot for this. I finally got to listening to Earth's discography - "used" it a lot in the past few months (found it perfect for reading while insulating myself from traffic din) - and I love Bruce.

Thank you for saving us from the Pontifical Drone. Everyone exhale.

Just reminds me a little on first LP release of Tangerine Dream "electronic meditation" in the year of 1969 of the last century.
The artistic expression is very familar, although not quite the same.

A very lot of German musicians did a lot of similar stuff in the early 70's cause they were unable to play "powerfull" rhythm. The invention of sequencer changed a lot opening the door for the Techno scene.
