"Wall of Sound" - worth a try?

In the interest of experimentation, I am wondering whether it would be worthwhile to try an experiment driving a 'wall of speakers' consisting of four 12's and eight 10's.
In order to make it work, I would need to invest about $40 or $50 in a couple more speaker cables. Is it worth it to give it a try, or just silly?

My amp is capable of driving 2 ohms, and the arrangement would work out to be exactly 2 ohms with everything perfectly balanced.

Note: This is just for having fun playing at home, because (a) I love bass that I can really feel (and I'm happy to practice with earplugs so I can feel the bass), (b) I am not even in a band at the moment, (c) I would never need this many speakers on any stage anyway, and (d) it's fun to see what things I can knock down off the walls and shelves upstairs.

The arrangement would be:

1x12 z8, 116w \
z4, 232w
1x12 z8, 116w /




4x10 z4, 58w + 2x12 z4, 58w \
z4, 232w
4x10 z8, 116w /


Then the two z4's in parallel makes z2, 465w

Cabs, in order of mention, are:

Harry Kolbe 112 z8
Harry Kolbe 112 z8
Berg AE410 z4
Berg HD212 z4 (or Barefaced Super Twin z4)
Eden D410XLT z8
So basically I'll get to hear how you sound through that AE410 I sold you - without having to leave home?

:D

Not practical, no. But it does sound like it could be a ton of fun to play through just for kicks!

Hell, I'm trying to get to the point of having no need for any cabinets!
I have a few different rooms in which I practice and I don't like moving equipment around, especially cabinets.
Sad part is I mostly play at night with headphones.
But when my wife and kids disappear on a weekend day and I'm home alone, that's when the big guns come out!

I have a drum set and PA all set up in one of the rooms as well. Hoping a drummer, guitarist and singer will magically appear some day...
 
I know you want to use the cabinets you have but I haven't used a 410. I had two different speaker rigs.

One was an Aguilar 210 and a 115. I drove them with a Thunderfunk TFB-550B (550 watts at 4 ohms). The other cabinet was an SWR Henry the 8x8 (eight 8" speakers) Both of them were capable of blowing your skirt up further than 10' feet away. Beyond moving your skirt around, they thumped in your chest enough to cause heart palpitations. If I let them go into feedback, you had to move away as the Aguilar rig would let go on a low A and feel like your head was about to explode!

Good luck with your cabs. Please don't fry them!

I know there is currently a thread on a vertical 4x8. I only have experience with the 8x8. It's a stunning sounding cabinet. I imagine the 4x8 will be similar.
Again, I can't comment on your proposed wall of sound but good luck.

Is it safe long term?
Sure, absolutely. As long as you are giving your amplifier the impedance it wants, it will be happy. It makes no difference whether the connections between the speakers are done inside of the speaker cabinet or inside the amp or in a remote box like this one. Same net result. Just that if you happen to need series connections, the most likely way you're going to need to get them is with a box like this.

Kinda opens up some possibilities for amp/cab choice. I've sold amps because they didn't' do 2 ohms. I"m ok with more drivers but cutting the power in half and going to 8 ohms in some cases.
 
I'm aware, But I love what Spector did for production with layering, so I shamelessly link and reference whenever I have something like an excuse. It's the only reason I clicked on this thread to begin with!
:D

-I really like threads like this, not because they produce usable practices, but because I endorse sonic mayhem.
This is the bass equivalent of "Drink! Drink Drink!" :P
 
For me, in the places I typically play, there would be simply no room on the stage for that many speaker cabinets. I use a vertical stack of a pair of 2x10s. One night a band leader I worked with told me that my amp was way too big for the place we were playing. Meanwhile he had six instruments ranged in an arc in front of him taking up most of our side of the stage. If he'd seen the OP's suggested set up he'd have had a heart attack!!

Ha! Sorry, I should have made it more clear that this is an experiment for home studio enjoyment only.

For playing out, I would use either a single Harry Kolbe 112 for a smaller venue or the Barefaced Super Twin for a larger venue. Coincidentally, each of those options weighs the same 36 lbs. I cannot ever imagine needing more than one or the other of those on stage.

I merely wanted to experience LOUD

screw 'em. Life is short. Make some noise
Don 't forget to post pics
:D

good luck! :thumbsup:
 
I use to use 3 SVT's driving 2 V4B and 4 STV flat back 8x10's. That was good but not enough so I went to
4 EV 18" Theil cabs, 4 2x15 EV Theil cabs, and 3 EV Constant Directivity horns with D1202 drivers (IIRC, it's been a long time) powered by a rack of Crown amps and a 3 way crossover. The preamp was an Ampeg B25 (with a TL606 cab underneath to please the tube poweramp). That was loud and clean. Then I hit nirvana running 2 SWR SM900 heads, 2 Goliath III 4x10 cabs, and 2 GoliathJR II 2x10 cabs - stupid loud, made the Warwick thunder, and clean. Could right size the beast for the gig.

Now I'm close to 60 and want something light (Genzler maybe).

All I can say to that is WOWWWWWWW.
How is your hearing? Did you consistently wear hearing protection?

what hearing? ear plugs? what were those? When I was running the SWR gear I had hearing protection. In the 70's no. I use to have to retrieve my friend who would climb up PA systems and howl at the moon, we would be lucky to be able to hear 3 days later (I use to see SRB at the 2nd Chance in A2 every Monday that they played there). When I had the full on EV stack I would move it as far away from the drummer as possible and stand betwee the drummer and my amp, cut down on having my heart rate dictated by my bass amp. Poor shlubs in the front row that use to bang their heads to it. I've come to terms with my very loud tinitus. Long live Rock:bassist:
 
You will be lucky to avoid a total 180 phase reversal on one set vs the rest. That could get very ugly for the odd ones out as they would get a extra shove in their opposite direction by the rest of the pack going the other way. Kablooey.

First all the cabs have to be wired + out.

Then all the linked amps have to be firing same way.

And your linking boxes have to be correct.

You should add in bits at a time to make sure each bit makes it louder. Take away a bit and add a different bit. Rinse and repeat until you are dead sure it's all in phase.

...He had a motley assortment of low wattage cabs that he drove with a 200W tube PA amp. Some cabs were getting next to nothing and others half the amp output and he wondered why he kept blowing drivers. It sounded disgusting with very little bass, probably because of phase issues, so he cranked the bass and just got farting and blown drivers instead.

The tube amp packed up and he brought it to me to fix and at about the same time he came by a pair of half decent PA cabs (on poles) and a matching SS amp, it sounded so much better!

I still have the tube amp (now fixed) in my garage but refuse to give it back because I know that if I do he will start using it again because "more is always better" and just go back to bad sound and blowing drivers again.

I wasn't asking permission so much ask asking if anyone else has tried something similar and had either a good or bad experience. I am really glad I asked the question, because I was only thinking about arriving at the proper impedance and I had failed to consider the unequal power distribution across the drivers. So I am going to rethink it, and probably will end up connecting two 4-ohm cabs to one amp to get 4 ohms, and connecting two 8-ohm cabs to the other amp to get 4 ohms there as well. My goal is to stand in front of a massive wall of moving air just to experience that. (I never got to see The Who in concert.) Like many of us (I assume), I LOVE feeling the bass. I have six cabs in total, but three are 4 ohms and three are 8 ohms, so I can't really use them all as I had hoped.

If I merely wanted to experience LOUD, the Barefaced Super Twin all by itself is more than plenty loud to cause total deafness very quickly. Then again, I think the Berg AE410 is too. But I am not after just obnoxious loud volume. I wanted to see if I could get a nice and clean sounding massive wall of air movement with all of that speaker surface area available.
you have been twice and now thrice warned about potential for mis phase blowing up part of your wall.
