I'm not saying you shouldn't strap the 818 to the 828, but I don't see why (without a strap) it would be any less stable than if the 818 was on the floor?
And the fact that you likely need shorter pole, I think there would be less likelihood of tipping, than just the 818 on the floor.

I just found the ANSI definitions. So 99.9 kV is considered "Medium" voltage. Holy crap...

Voltage classes: (ANSI C84.1-2016)

Low Voltage: 1000 volts or less

Medium Voltage: greater than 1000 volts and less than 100 kV

High Voltage: greater than 100 kV and equal to or less than 230 kV

Extra-High Voltage: greater than 230 kV but less than 1000 kV

Ultra-High Voltage: equal to or greater than 1000 kV

And the dielectric strength of air is 33Kv/cm so in those upper ranges things can get exciting real fast when you're not careful.

I wonder if it could be done with one switch though.

Yes, technically you really only need to switch the positive connections to take the crossover out of the circuit.

Yes I have. They were very common in this part of the woods back in the 60's coming straight from England to New England. The B3 player for one of my bands in the 60's bought one for his VOX Jaguar, then proceeded to sell the Jaguar and leave the amp at my house for the next year. Side by side with the Fenders and Marshalls of the day they were always brighter by comparison, and my memory hasn't changed. I'll back off a little on the mid range, but the top end still seemed much brighter than it should be, almost brittle when compared. You have to remember my guitars at the time were just as they are today. Gibson's with humbuckers and one lonely Telecaster. Now if you play a Moserite, Gretch, or Rickenbacker through the same amp you'll be in heaven, IMO and YMMV.

Both of the units I mentioned have adjustable hold times on the relay and adjustable relay activation thresholds.

I am very much a DIY type of guy and have had a soldering iron in my hand since the 6th grade (about 1973) but when something like the Bogen VAR1 is available and worked perfect for my strobe light project why try to reinvent the wheel. I just package it with the strobe light using a project box, I also needed to build eight of them.

Makes sense-
Thanks again!

Remember, these are SINGLE 4" speakers (in an array of four speakers) so it's definitely nothing to write home about.


Tell that to BOSE.

You don't need 2 speakon connectors to do this but they can be useful other ways. This is what you need electrically.. 1 DPDT switch for the LF section and another for the HF.
Nicely done!

I think I see what you mean - this could be done with one 4-pole connector (?) And the same standard 4-conductor cable.   Position 'A' could use 1+ and 2+ only for when it's mono, lifting the negatives to prevent a short.  Position 'B' would switch in 1-/2- and re-route directly to drivers, bypassing the crossover.
Then I wouldn't even need to use a different cable (or adapter at the amp-side) for mono vs when it's bi-amped.

I wonder if it could be done with one switch though.  Seems like it might get confusing if someone other than me sets up the rig? Or stupid me would forget to switch both and think I'd blown a driver, LOL

I would imagine by just the weight of the 818 alone, would keep it quite stable. I would cheat a little and move the 828's out a little so that the feet cups line up with the feet of the 818. This should leave about a 2' gap between the 828's, which may or may not have adverse effects? An idea anyway.

I've just ordered a SRX828SP to add to my current pair of 818's, and trying to understand all my options for deployment.
I was tempted to just buy 2 more 818's, but the 828's are much better value per box locally.

I like using my 818's as FOH stands, things are much neater (and hopefully safer) without tripods around punters.

I'm wondering if anybody has experience mounting a single 18" on top of a double 18", then still using a distance rod to mount the FOH speaker on top. This would make a triangle looking stack.
Here's a rough example of one (perhaps bad) option I have in mind:

I expect that I will need to strap the top sub down tight to the bottom one.
Note: I haven't even tried this in my garage yet, and I don't always have much time to sound check in venues, so really want to walk in with a firm plan of action.

This would be for indoor venues, so top of the FOH cab will be approx. 5' from the ground.
Bigger venues or outdoors, I will experiment with either having the 828 in the centre of the stage, or also standing it upright next to one side's 818.
Depending on stage height it might make a foldback stand somewhere in the centre of the stage, but I need to better understand how spacing subs like this would impact the low freq on stage and for the crowd.

I may just decide to always cluster 3 subs on one side and have 1 on the other.

Any insight is welcome.

That would work if the mono channel inputs were steteo.
