Massive rig question

[Reemo_bassist]

Hi,

Returning after three years (!).
Recently been playing loads of bass, started listening to Dream Theater and Type O again...the good old days...

OK, so I have two 15" cabs (no idea driver, as given to me by church and it's 0120 here, so no opening it, two Eminence Beta 12"s, two eminence beta 10"s and two horns with crossovers.

I'm thinking of buying another two 18"s, and so to have a :
2x18", 2x15", 2x12" and 2x10" monster rig. Just for a bit of fun .

Pic attached of one of the cabs, my Firebass 700 and Ibanez BTB.

BTB and a firebass eh? nice

I've missed my babies. I went through a very odd non-musical stage 2002-5. Back in business. bit rusty

 

[FunkSlap89]

That would be a MASSIVE rig...

i don't know if that amp could power all those cabs

 

[ModulusFan]

As long as you can find an amp capable of running .5 ohms without spontaneous combustion, you'd be fine.

Trust me, don't try it.

 

[Reemo_bassist]

No, I have an idea of how to wire...I think the firebass' outs are paralleled.... so have an 8 side (all wired series-parallel) and a 4 ohm side *thinks about how to achieve this*

 

[Reemo_bassist]

there is a way. Kinda complicated, but hear me out.
Series-parallel the 18"s and 15"s, so that = 8 ohms.
Do the same to the 12"s and 10"s, also = 8 ohms.
Now buy two MORE 10"s, and wire those in parallel. 8/4 = 2 = 700w

Or just lose th 15"s/18"s. Losin the 15" would be my preference

What are you going to do or play with all this? Seems a bit nuts to just crank it up in a bedroom...

~S~

PS: What's your $$$ budget?

 

[Reemo_bassist]

turn up to rehearsals...and crank it up

I see what you are doing with the 2 overall 8 ohm loads, but dont get how you are adding the 4ohm load ontop of that

Up to what? when i use my peavey 410 and 215 with my firebass, i cant get past 2 on the master volume without the room crumbling

 

[Reemo_bassist]

with two more 10"s. in parallel.

 

[Reemo_bassist]

.5 .

I may lose the 15"s though, makes it all alot easier

You can't have a "monster rig" without at least a couple 15's in it.

I dunno... I'd just get a big ol' poweramp to run all that, but that's just me.

Oh, and some roadies to haul and set it up for me. Maybe a conversion van for transportation. And maybe a venue to actually support something so ludicrous.

 

[mikemulcahy]

For everything you want, your gonna need more than "a" big ole power amp. I run 2 410's with a 1400i apiece, 2 118's with a Crown powerbase3 on each of them. Headroom with a big rig is important.


YMMV

Lol, that would be an impressive rig. You'd be one of the few guys playing through their own sound-reinforcement PA system!

Drummer's will be beating a path to your door (from something I heard about drummer's always aspiring to have their own PA)

Neat project though; go for it

 

[DEVILMAN]

...indeed...pics of it if it ever becomes...

~S~

 

[Trevorus]

Just get a poweramp, and run the whole shebang with 1 of each type of driver on each side. Should come out to 2 ohms per side, right?

 

[Dan Molina]

get a speakermate to connect all that together.
