Who is running a Super Redhead with a 4 ohm extension cab?

[Rusty the Scoob]

Looking for some real-world experience. The specs say I can run my Super Redhead with a 4 ohm cab... do they really hold up to this in real life? I currently run it near the pont of clipping almost all night with no extension speaker, and by the end of a gig it gets almost too hot to touch.

Very often combos are designed with a speaker that uses the full capability of the amplifier section. Some have extension jacks that are wired in series with the internal driver. The manual should tell you what type you have. If it is the former then with no extension you will be getting the maximum wattage and if you add an extension the output will fall.

I believe it's designed like my old Ampeg BA500 2x10 combo. 350 watts by itself, and 500 watts with a 4 ohm ext cab. Not only will the amp be louder due to the extra speakers, but it won't have to run as hard to get you there.

I've done it, it works great. I've ran mine with a 4 ohm (non-tweeter) Bag End 210, and it sounded great, and was plenty loud, including outdoor venues. It does get warm, but my understanding is that that is within the SWR design parameters. Just make sure the fan is on. I bought mine new in 1998, and have never had any issues with it.

I have used a redhead many times with an extension cab. Adds wattage, ads speaker area, and makes you less likely to blow the redheads speakers which seems like a popular option.

I run my super redhead with a 4 ohm Goliath Jr. Here's my story: I played an outdoor show with my Fender Jazz V which has a particularly strong B string. The band was loud, and I was dumb enough to try and keep up. Popped both speakers.

Once I got them fixed, I did two things. 1) I bought the Goliath Jr, and I have almost never used my Redhead without it since. And 2) I don't try and keep up. If the band is too loud, its too loud. I'll turn my amp off before I'll turn it up past where I'm comfortable.

The redhead the goliath is a whole different animal. Where the redhead alone is a bit weak in the low end, and a little on the "sterile" side, the redhead with the goliath is fuller on the bottom end, and a lot warmer and rounder, while still retaining all the "good" parts of the redhead tone.

The extension cab makes a dramatic improvement to this amp, IMHO.

i use a 8ohm goliath Jr as that was the one stated to use in the user manual. i think i would actually prefer a 4ohm cab but why would SWR say to use a Goliath Jr. III 8ohm model is a 4 ohm should be within the specs?

no one?

no one?

I saw that in the old Super Redhead manual (it is not in the current manual). That doesn't make sense to me, since the internal cab of the combo is basically a 4ohm Goliath Jr.

Since that combo is safe to operate at 2ohms, the 4ohm Goliath would make more sense, since all four 10's would then receive the same amount of power from the amp.

The only reason for recommending the 8ohm Goliath Jr. that I can think of is that, at that time, all the other free standing SWR cabs (if I remember correctly) were 8ohm only. So, they might just be making sure nobody gets confused and uses two 4ohm GJr's as extensions. Who knows!

 

[Berger912]

i wonder if anyone wants to trade their 4 ohm Goliath Jr III for my 8 ohm Goliath Jr. III? Mine is in excellent condition.

I owned and ran a super red with a 4 ohm 210 jr for yrs with no problem. Great combination!

 

[Berger912]

what speakers should i put in the Goliath Jr III to up grade the sound and lower the ohm to 4 ohms

 

[seventhson]

i ran a super redhead with a bergie nv610 and it sounded fantastic.

I have a Fender 400 PRO with 2X10,It also has an extention speaker that says 2 OHMs..........So I take it it has to be a 4 OHM speaker cab......At least thats the one I use and it sounds great........

I run a Redhead with a 4ohm Goliath Sr. Both 2008's. Fantastic Rig!

I use a SWR Son of Bertha 15 under my Redhead. I play a lot of old soul and R and B and really sounds nice with plenty bottom end without losing definition.

i think i just need to get a 4 ohm cab under the super redhead. The 8 Ohm goliath Jr III needs to be upgraded to 4 ohm. if i am going to upgrade should i get the stock 4 ohm speakers from the Goliath Jr IV or the Deltalite II 2510 what do you TBer's think.
