Hey Amp Gurus -

I'm downsizing my guitar rig. I'm playing all kinds o' R'n'R with a Casino and a Riviera. But...

I want to run my Ampeg V4 (100 W) through a Sunn 2 x 10 cabinet. So, what speakers to use?

Naturally I'll need some heavy duty wattage to keep the speakers happy. I don't want any speaker distortion necessarily, as the amp sounds great clean and with an effects chain.

Please let me know what you recommend! Thanks!!!

I run my Fender SCXD through a vintage 70's JBL 10"; however since like me you seek a clean (read hi-fi) uncolored sound from the speaker and have a higher-powered amp to deal with, I'd look at some of the neodymium speakers or other types that are of a modern clean sounding design. Alnico magnets are popular but there are good ceramic speakers too. I've kept my old JBL, Gauss, Fane and other speakers so rarely buy new ones.

Lots of options.....speaker experts?

Weber? EV? Jensen? which magnet and model? I've never been a big Celestion user, so I have no idea if they make any uncolored speakers. They do make some rocking speakers if you like speaker breakup...which I only do when somebody else does it.

Jensen would be my choice for 10" speakers. Only problem is I am not sure if they offer the higher wattage option. The jensens 10" speakers I have used and loved were low wattage amp speakers. The other recommendation would be to research the celestion options. I assume they have 10" speakers capable of handling the higher wattage.

Eminence Ragin' Cajuns?
Eminence Copperheads?
Or one of each perhaps?

Two 50W speakers wired in parallel will have you covered for the 100W output. Remember that the parallel config will cut your total impedance in half - ie. two 4 ohm speakers in parallel = 2 ohms total, two 8 ohm speakers = 4 ohms, two 16 ohm speakers = 8 ohms.

You can get a good selection of Webers in 40 and 50W in both ceramic and alnico models. If you want something really special (they're spendy though!), Tone Tubby makes some awesome sounding alnico models - reds are rated at 50W and blacks at 65W. I think Celestion Golds come in 10" now, but I've never played these.

from the article "This is Greg Martin's* favorite 10". He has them loaded in his Super Reverb! He suggests using this speaker in recording studios as well as in 4X10 cabinets for live gigs. Greg describes the tone as very 'jangly' with a meaty low-end and lots of honk. It would be a perfect speaker for anyone playing Country, Blues, or Rockabilly. This speaker works well with Rickenbacker guitars, a Super Reverb or a Super."

I'm not sure if that is uncolored enough for the OP - it sure is NOT what I would think of, no matter how good it sounds in specific applications..

All these other speakers that have been suggested - which ones are a fairly flat, even, smooth, "hi-fi" sound - those guys that have played through JBL and EV loaded cabs know what I mean.

These types of speakers may sound "harsh" to some ears because they are less flattering to overdriven guitar tones, sloppy playing, string balance, etc.

You get what you put in - nothing comes out "sweeter".

The bad is that there is no particular help from the speaker to cover or add to certain styles.

The good is that there is no added color nor LACK of color in the tone.

Maybe I misunderstood the OP's needs in his request: "I don't want any speaker distortion necessarily, as the amp sounds great clean and with an effects chain."

Right - so you choose speakers to match the output impedance of your amp.

So if you need 8 ohms, you get 2 16 ohm speakers.

I snagged a pair of old Jensen 12's from an old organ and they now are in my main 2 12" cab. They even handle bass at moderate volumes since they were made to handle bass pedals and not to color the tone much as the organ had a full range of sounds.

I'd take good look at Eminence speakers. If you want to limit speaker breakup (the speaker distortion you mention), look for speakers with ribbed cones. they resist breakup better, though they aren't necessarily immune to it.

IMHO, the linear quality of the JBL/EV type speakers might sound really harsh for "all-rounders" in an Ampeg V4, albeit the cleans would sound stellar. As such, the OP might wanna try something with character given he's into R'n'R.

After re-reading my first post, I'd probably lean more towards something with ceramic mags in a closed back cab. Ceramic mags are a little "faster" than alnicos and generally do a little better in that environment. Alnicos or alnico/ceramic combo if it were open back or partially open back, however.

Thanks, y'all. Lots to consider, just as I had hoped.

Hey, dbb, since you raised the question of wiring: should one wire a cab series or parallel and why?

While you wait for an answer, you might find this helpful, or confusing.

If you wire two 8ohm speakers in series you get 16 ohms.
If you wire them in parallel you get 4 ohms.
If you wire two 16 ohm speakers in series you get 32 ohms.
If you wire them in parallel you get 8 ohms.

The formula for series wiring is
R1 + R2 = total resistance.
You just add them up as you go along.

The parallel formula is

R1 X R2
_______

R1 + R2

You multiply the resistancees of the 2 speakers, then you take the result
and devide it by what you get when you add them up.

The reason for wiring them differently is that you want to match the
impedence of the speaker load to the output impedence of the amplifier or
at least come as close as possible.

If you can't match them exactly it is better for the speaker load to be
higher than the amplifier output impedence than lower.

Dudes, you're awesome. Thanks.

Still haven't bought one, but am leaning toward the Eminence Legend 1058.

Tony gave a great answer....basically you need to match the amp and cab. So it will depend on the speakers and the amp's resistance and you can reference Tony's reply.

Thanks for the explanation, Tony.

Hey, dbb, you mentioned Gauss speakers. I know nothing about them except that was allegedly what Steve "Sex Pistol" Jones loaded in his Twin. What's the mystique?

Just another high-fi type speaker, with a big strong magnet. Made by Cetec.

"Gauss speakers are very high grade speakers on par with JBL."

"I used to use a Gauss 12" bass speaker for guitar....I NEVER should have sold it...It sounded great...can't buy them anymore...The speaker was rated for 400 watts RMS!!"
