SWR Cabs: Goliath II + Jr. II? More questions!

[Senator]

I have a chance to get a G II for super cheap. Has anyone ever paired a Goliath Jr. II 2x10 with a Goliath II 4x10? The Goliath Jr. II is 4 ohms 250 watts. If the Goliath II is 8 ohms 500 watts, would it be worth it to rewire the Jr. II to 16 ohms and pair them to get an even 6x10 or leave the Goliath Jr. II for small gigs?


I also have an 8ohm Goliath Jr. III. Should I wait for G III or G Jr. III cabs to pair up vs. the G II cabs?

Your rewire scheme is wrong. It would so not be worth it any way you want to jive it. You'd have wire everywhere and both cabs would be less than useful by themselves. Or else your cabs wouldn't share power equally between drivers.

A 4 ohm 250W 2x10 is a handy little cab to have.

See post #4 or #5.

Hmm....

I have an old JR II, which I bought used for $100. I run my LMII through it in our rehearsal room. That little cab is decently loud and pretty deep for an old 210. It was marketed as an extension cab for the Redhead, and not really intended as a standalone. It's a heavy little mother too.
IMO, it would not pair well in any way with a Goliath II 8 ohm.

I too feel that it's a "handy little cab" but I've read so many positive reviews on the Goliath II and was wondering if it would be practical to add it on.

My original plan was to get another Goliath Jr. III, but this big cheap thing came creeping.

Thanks for the reply, though.

This gives a total load of 5.3ohms, and all speakers receive the same power. My weapon of choice.

Engaged my brain in reverse gear this morning.

I am still confused, bump.

The 2x10 gets more amp power than the 4x10. The 4x10 is coasting. I've done it. The 2x10 sounds way too loud. Won't do it again. If you have a stereo amp and can manually balance between the two amp sides that's okay. Each has it's own ohm load and you aren't in danger of putting too much to the 2x10.

Ok, I've been one of those who has raved over the goliath ll 410. Mine was 8 ohms. It co-existed uneasily with everything but an Epifani NYC 210, but that is another story.

The G ll is a great cab. IMHO, a 4 ohm G ll cab is ideal for pairing with an 8 ohm Gll 210. As long as there have been no irregular replacements, you would now have a modular SWR 610 of the G ll persuasion. Nice.

However, the cabs you are considering don't have the right impedance to do that. Get the G ll 8 ohm, or just keep looking.

BTW, I got one of those for $220 in 2001 in Santa Cruz, CA. Still miss it in a way...

yes, when you rewire the 4 ohm cab to 16 ohms the impedances combine so all the drivers are each making the same power. The 8 ohm cab will be making twice the power as the 4 ohm cab and the whole thing will be a teeeeeeny bit louder than the 8 ohm cab by itself.

The two channel amp idea is how I dealt with pairing the 8 ohm G ll with other cabs, like the epifani NYC 210.

In fact, if you have a power/pre rig, you can just run with the preamp input mapped identically to each of the channels—though every situation is a little different.

What I am saying is that the individual channel input reduction on power amps allows one to balance the power sent to differing cabs, like an 8 ohm 410 and and 8 ohm 210 or 115. However, blending together an 8 ohm 410, and a 4 ohm 210 would be a challenge, IME.

Probably not worth it. You need to fully double power to get 3dB extra output. Adding 50% is like bumping a slider 2dB, barely noticeable. Not that I've tried it with cabs but the maths is solid.

Since you already have an 8 ohm one I'd definitely pass on this one and get another one of the 8ohm ones to make a 4x10 vertical stack.

[Senator]

Thank you for the detailed replies, everyone!

[Downunderwonder]

OOOPS, I forgot about the extra smidgeon of sensitivity you get from adding two drivers, so there's maybe 4dB extra loudness in total, you can hear that, still not well enough to want to do it if you ask me.
