swamp thang in a 1912 update

[Uk Ant]

A few weeks back I purchased an eminence swamp thang to load into my Marshall 1912 1x12 cab, which sits under my Mesa express 5:25 amp.
Last night was it's first gig and I must admit it really does cut the mustard next to the G12B that comes as stock in these cabs.
First off both speakers have pretty good bass response that the baby cab really needs. Tone wise the swamp is just a bit more articulate in response and sounds more alive, difficult things to really quantify.
The Big difference was volume. Just because something is more sensitive on paper does not mean it's going to do the business out in the real world but the eminence really delivers at gig volumes. We only use a vocal PA so I'm only competing with a really loud drummer with a really loud kit.
Last night was the first time since I stopped using my old Ashdown that I've really been able to truly compete.
All of a sudden I can hear myself well, got some seriously tasty feedback sustain and could really get into each note a phrase so much more than on previous gigs.
That done I micked up the cab just spread the sound front of house more... which seemed to work a treat.
I actually got complimented on my tone last time we gigged people were asking me to turn up.

All in all £60 well spent.
Only down side of the night was my stinky cold meaning I was turning away after singing each line to have a good cough.

Glad to hear you're enjoying the Swamp Thang. I use mine in a 6505 112 combo, unfortunately the cheap board it's mounted on isn't holding up so well with the bass and the screws are getting loose! However, it's still a great speaker.

Ooh, just remember I had a picture of my baby rig monster doom

Cool review. I've been contemplating a swamp thang myself.

If your after a dark, syrupy tone I'm not sure you can get better.
Plus they're pretty loud.
I'm tempted to get a couple for my 2x12 when I've got the cash.

I love the swamp thang demos, but I also love V30, as I've played through them. How would they do in an X with V30? in a JCM900 1960A?

Re: swamp thang in a 1912 update

maybe it's a cute little phase I'm going through, but I'm sure that a single ONE of these sounds better to me and BIGGER to me than every other Celestion and any other speaker or sets of speakers in any speaker cabinet that I have ever used, regardless of size, shape, number of speakers, mojo, funkulaciousness, thump, grunt, beep, adjective, orientation, europeanation, africanation, any other ation, ism, thing, place, Oort Cloud, item.

edit: I believe the *slightly* open-backed Avatar it sits inside, and its eye-slapping blue color, have something to do with that as well. More of an oval-ported back, not an open back. Lets the speaker breathe. As a result of this one box, every sealed cab I've tried since including my Bogner cab sounds like Siamese elephants joined at the trunk.

I've not actually used a V30, although it was on my shortlist.
I suspect they may be a tad too similar to work in combination mind, although some one with more experience of the V30s may be able to tell you otherwise.

What about ohmage/whatage crap, are the compatible? sorry electronics retard here.

The main thing to check when using different speakers in one cab is the impedance (ohms) the swamp comes in both 8 and 16 ohms, in a 4x12 you usually have four 16s in parallel to give you a 4 ohm cab, although other options are available.
I'm pretty sure the V30 comes in various different impedance so matching those should not be a problem.
power rating is a different matter but as long as you don't try putting more power than it can take.
So if you're driving a cab with, say, a 100w head the total power rating of the cab has to be at least 100w or you may damage the speakers.
V30s can take 30w each so four of those is fine. Something like a swamp thang can take 150w so it's pretty hard to blow up.
As long as you match impedance you'll be fine.
Get the impedance matching and your wiring wrong you could end up with the bulk of the power going just one or two speakers, which may end badly.

Re: swamp thang in a 1912 update

V30s are 60 watts, not 30.

a 4 ohm 412? me, I have never met a 4 ohm 412. They are usually 16, sometimes 8. My Uberkab I just traded was 8 ohms, the new ones are 16.

My Krank cab is actually 4 ohms.

Whenever you use a cab with different wattage speakers, you just multiply the lowest rated speaker by how many speakers are in the cab. So if you have a 412 cab with two Swamp Thangs and two V30s, it's 60 x 4 = 240.

Re: swamp thang in a 1912 update

Thanks dudes. I use Laney AOR Pro-Tube 50 watt, so I should be fine. However JCM900 1960A does have a choice of 4 and 16 ohms. I actually prefer 4 ohms tone to my ears its more crisp and spanky. But I guess V30 dont have an option for 4 ohms wiring.

Oops, my mistake.

we are each allowed one mistake.

Re: swamp thang in a 1912 update

4 x 16 ohm speakers wired in series = 4 ohms total.

 

[tonefreak1527]

Re: swamp thang in a 1912 update

^no, thats 64 ohm, you want parallel

 

[PVFan]

Re: swamp thang in a 1912 update

that's actually 7 million ohms

Re: swamp thang in a 1912 update

If you have four 16ohm speakers you can wire them various ways.
First, all in parallel = 4ohm cab.
All in series = 64ohm cab (a bit useless really).
Wire them in two pairs of parallel and then run these in series you get 4ohm.
If you're cab can switch between 4 and 16 then it probably switches between option 1 and 3. Probably not the easiest cab to re- speaker as it will have a more complicated internal wiring than some. That said as long as you replace like for like in the ohm department then it should be easy enough.
You can do a similar trick using 4ohm speakers.
The reason you rig will sound better on one setting than the other is probably because you're closer to the output impedance of the amp.

Re: swamp thang in a 1912 update

Wire them in two pairs of parallel and then run these in series you get 4ohm.

When wiring in series/parallel, you get the ohmage of the speakers used. Parallel wiring the 16 ohm speakers into pairs makes them 8 ohms each pair, then you do a series connection which bumps the pairs back out to 16ohms.

Anywho...all these mini rig-of-doom threads really increase my gas for a vertical 2x12 loaded with C-rex speakers for my little single 6L6 amp head.
