Not that I've seen.

@RNG1 --- Memo received ---That is a good point and we will get that done. Actually I thought we had a pic with 3 SLT's but this is what we do show on the website -- (from the floor up) SLT/STR/SLT.

I don't know if I can convince my wife to buy me another Genzler bass cabinet, but still I would like to know the various options to correctly connect these three cabinets from the 800.

I've never been to a Grateful Dead concert, but I have seen these walls of speaker cabinets. But aren't there lots of empty, driverless, cabinet shells mix in that construction?

Not in the Deads wall of sound! 600 speakers all full of drivers.

I just run a speakon to the top cab, and then daisy chain them on down... which, as I learned on the previous page, is a series connection

 

[Holdsg]

let's see if I can do the math right.

STR solo - 8 ohm
SLT solo - 8 ohm

STR bottom STR top - 4 ohm
STR bottom SLT top - 4 ohm
SLT bottom STR top - 4 ohm
SLT bottom SLT top - 4 ohm

STR bottom SLT middle STR top - 2ish ohm
STR bottom STR middle SLT top - 2ish ohm
STR bottom SLT middle SLT top - 2ish ohm
SLT bottom STR middle STR top - 2ish ohm
SLT bottom SLT middle STR top - 2ish ohm
SLT bottom STR middle SLT top - 2ish ohm
SLT bottom SLT middle SLT top - 2ish ohm
STR bottom STR middle STR top - 2ish ohm

410 - 4 ohm
410 bottom STR top - 2ish ohm
410 bottom SLT top - 2ish ohm

FYI three 8 Ohm cabs together would be 2.67 Ohms, which the MG800 can be switched to go down to. Two 4 Ohm cabs would be exactly 2 Ohms, which the MG800 does not handle IIRC.

 

[Holdsg]

that's why I said 2ish. I didn't recall the exact decimals.

 

[Discount Saint]

Yeah, but it is worth noting that 2.67 Ohms is a very different situation than 2 Ohms. The MG800 can handle 2.67 Ohms (3 BA 12-3s), but cannot handle 2 Ohms (2 BA410s @4ohms each).

 

[Holdsg]

now you have me curious.
I'm never going to do this, but its not like you're going to blow up/melt your Magellan head trying to handle a 2 ohm load (when the lowest it would go is 2.67), but it wouldn't be electrically efficient, and probably not musically satisfactory?

 

[Nightman]

Okay, so you can't stack two 410-3 with the 800 because they are both 4ohm cabinets, but you can stack a 410-3 and another 8ohm cabinet and run those with the 800 set to 2.67.
But isn't that still based on parallel or series connectivity?

As I understand it you can definitely kill an amp trying to run at a lower impedance than it is designed to handle. I've heard many stories of amps melting because of this. Perhaps 2.67 vs 2 Ohms isn't enough of a difference to kill the MG800, but certainly trying to run at 2 Ohms on an amp designed to go down to 4 Ohms can make things go boom.

I think it's always going to be a series connection in our case, unless the head has multiple power amps with their own separate loads. My band's PA does this, like it's rated to put out 800 Watts total, but it actually has two separate power amps which each can handle their own 400 Watt 2 Ohm load, so you can hook up 8 speakers total without actually going below 2 Ohms on either power amp.

In the case of most bass heads you're just dealing with a single power amp with a single load, so each additional cabinet will directly influence the load.

In the future I will get a SLT to use on top of my 410-3.. Or on small acoustic gigs.

 

[svtb15]

I have run my MG800 @ 2 Ω's without issue.. It was way too LOUD for what i needed but I had to try it .

By this statement (BOLD) you mean with Genzler 800 amp and cabinets? The panel on the back of my Genzler cabinets (410-3 & 12-3) have two 1/4 females marked PARALLEL, which I assumed is to be used when connection to additional cabinet(s). I guess I need a Bass Cabinet Connectivity 101 course!

Sorry, I wasn't very clear - The connection itself may be series (one cable from each cab to the amp) or parallel (daisy chain from cab to cab), but as far as the amp is concerned the load is calculated as series either way.

Yes, don't repeat this but we have a few players that run the MG-800 at 2 ohms. We feel that when using our cabs it is much "safer" than if you might be using other cabs on the market which may tend to have lower impedance than shown. You won't blow up the amp but if there were an issue it might be premature distortion or something along those lines. We have certainly overbuilt this design for any potential issue.

You mean parallel lol

Even two to the amp are parallel. And the load is always calculated parallel.

THANKS for saving us from ourselves!!!
