Did I just screw myself up?

[BurningSkies]

Since your bridging cable (should you decide to try things that way) will look like any speakon speaker cable DO mark it so you know what end of the cable goes to the bridge mount on the amp and that you know its a bridge cable not a regular speakon.

A quick and slick way is to use colored shrink tubing...My bridge cable is a bit different than yours, since my amp doesn't have a common bridge output, but it looks like this:

Red for channel one, green for channel 2. Black and blue shrink for stress relief and to cover where I've stripped off the outer layer of the cable and keep it secure. I certainly won't mistake this for a common speakon.

Good question. The amp is almost as big as the top of the 410. Maybe just put the 12 on the floor next to the 10.

Trying to post pics of the two and wondering how the heck I'm gonna stack these:

I'm thinking...there aren't many people in Hawaii that uses Orange cabs (at least I haven't seen any). With this small, compact set up, it is bound to surprise a lot of people if they aren't familiar with this product.

Just one more reason to get matching cabs ...

 

[kawika5150]

Maybe I'll put the 212 on top off to the side and put the amp next to it. Either that or both will be side by side on the ground.

Stacking them vertically would be the best arrangement although I would strongly advise ditching the 212 for another 410.

My GK 200RB is the same way. I tried it both ways (B.M. 1000w @4ohms) and (2x300w @ 8ohms each) and it was fine. The only way it mattered was when I used it for extreme volumes, then the BM came through better.

 

[kawika5150]

I'm gonna stick with this combo for now and see how it works out. Will try running both cabs through one power output (NOT in MB mode) to get the 4 ohms. I'll figure out the stacking arrangements.

I still can't get over the fact that these small cabs are capable of putting out some serious crank. Will find out for myself soon.

They'll move some air, that's for sure. Think of it as the equivalent of a sweet 410 rig. Don't expect it to take on an 810 is all I'm saying.

An isobaric cab loaded with two drivers has the same sensitivity, output and response capability of a standard style cab loaded with one driver.

I thought the 410 was the square one! I would like to see a cross section of this one...

.
The Orange Smart Power SP410 Bass Guitar Speaker Cabinet is a 1200 Watt cabinet with Isobaric loudspeaker construction.
The Orange Smart Power SP410 is based on mounting four 10" Lightweight Neodymium Eminence Speakers within the cabinet behind each other and in practical terms this not only lowers the bass frequency but also delivers more output from within a smaller sized cabinet.

A dynamic and responsive tone, built in the UK using marine quality Baltic birch plywood, the Smart Power cab is rated at 8 ohms and create an awe inspiring sound.

The Orange Smart Power SP410 Bass Guitar Speaker Cabinet Main Features Include:

1200 Watt
8 Ohms
4 X 10" Lightweight Neodymium Eminence Speakers
State-of-art bass speaker cabinets
Dynamic and responsive tone
Quality Baltic birch plywood

The square one is the SP212 and looks like my bento box.

Maybe my next acquisition would be another one of these SP410's so I can stack 'em like a regular 410 but have the driving force of an 810. We'll see. I'm confident I'll be pleased with these two for now.

Thanks Chris, I actually read that thread a couple of days ago. Every component will have its pro's and con's. Can't please everyone.

This rig, being that it's already so compact, should be just fine even with the stacking issue. They're confined to such a small area of the stage that I don't see it making a noticeable difference in volume no matter where I put the 212 (either on top or on the side of the 410).

If you put them side-by-side, you'll notice when you move off-axis. I suspect you'll have similar problems even stacked, but you'll reduce them as far as is possible, especially if you have the long cabinet up on its end.

Hmm, maybe I'll stack them like the letter "I" and brace them with something so it doesn't topple over.

[1] Connect both cabs (daisychain) to one side ("A") of the amp. This will give you a 4 Ohm impedance, and should be plenty of power.

According to the Ampeg specs on page 1, connecting them this way will result in 490 watts per cab @ 4 ohms, correct?

Nope, it looks like you're getting about 325w per cab when chained off of one channel. A total load of 4ohms, with each 8ohm cab getting half the wattage.

Got it. Thanks again.

Head unit is the 4 PRO, and its specs are as follows:

OUTPUT POWER RATING 1600 Watts Mono-Bridged @ 4 Ohms (1200 Watts Continuous)
1200 Watts Mono-Bridged @ 8 Ohms (900 Watts Continuous)
2 x 900 Watts @ 2 Ohms (600 Watts Continuous)
2 x 625 Watts @ 4 Ohms (490 Watts Continuous)
2 x 350 Watts @ 8 Ohms (300 Watts Continuous)

SP410 specs:

4 ultra-lightweight 10" Neodymium loudspeakers (300 watt)
Impedance: 8ohms
Output: 1200 watts

The SP212 is:

Impedance: 8ohms
Output: 600 watts
Weight: 44lb.

Let me see if I have this right...

If I need the most power, I'd use the mono-bridged output of the amp > SP410, then daisychain from SP410 > SP212. Are both cabs now running at 4 ohms each with an amp power output of 1200 watts thus now sending too much power especially to the SP212?

This is all very confusing.

Two x 8 ohm cabinets linked in parallel provide a total impedance of 4 ohms to the power amp component of you head (not 4 ohms each, 4 ohms total). When it is "pushing" against this impedance in bridged mode, the amp delivers a maximum of 1200W continuous, 1600 W peak (according to the specs provided). Because each cabinet has the same impedance, each will receive half this power (i.e. 600 W continuous). Each speaker in the 212 will see 300 W, each speaker in the 410 will see 150 W, which will be ample to destroy the drivers should you so wish!

Bottom line -- once you have them hooked up, LISTEN to them. If they start to sound bad as you turn up the volume, turn it down again. Not confusing at all.

The only reason I asked this was because of the response I received from Loud Tech Inc. whereas I would considerably be "underpowering" the cabinets despite the 4 PRO specs they were provided with. They did not give me a scenario where if I hooked up both cabs using the mono-bridged feature would supply enough power to destroy the speakers.
