I've done a lot of research over the last few days, FDP searches, internet searches, manufacturer websites and I have a few questions.

First, I play primarily at home at very low volumes. 2-3 on the volume knob. Occasionally crank it. At those volumes I will get my overdrive sounds from pedals. I play single coils, P90s and Humbuckers.
The original Oxford speaker sounds too muddy in the bass. I find I'm turning the bass all the way down to get a well balanced sound.

Looking at Ted Weber's site. They recommend the 10F150T in either 25 watt (for natural OD) or 50 Watt (if using pedals and you want it to stay clean longer). For my situation I'm thinking I want the 25 watt version but I'm concerned I might be overpowering the speaker too early if I use pedals.

Which should I pick if I were to go with Weber?

Some speaker ratings are like 75watt for an Eminence Cannibus Rex or a Copperhead.

Jensen C10R looks like it is the speaker of choice for Fenders. Also rated at 25 watts.

Also, I'm not opposed to getting a larger/different cabinet that I can load a 12" into. (the 79 has a glued in baffle).
Should I consider a 12"?

I'm confused.

What do you think would best fit my application.

A 25 watt speaker is fine for a PR. A Jensen P10R would sound real nice in your amp at lower volume levels.

If you want it really clean and want to go Weber put a 10" neo in it. A JBL D110F clone.

I like a little dirt. I can't really do 6-7 on the volume too often, which is where a 25 watt speaker will be when it starts to break up..
I just don't know if it hit a 25 watt speaker with a pedal is it going to sound like crap.

I'm thinking it will be fine and just take it easy with the pedal.

Speaker selection is a nightmare if you ask me. Many offers, but not any chance to test drive. OEM selection in the amps in the stores is very limited to just a few types.

Anyway, I'd not be concerned with a 25W speaker in a PR - should work fine with whatever you use.

In my opinion, many Alnico speakers do not take distortion very well - I mean high gain distortion. They sound good with just a bit of overdrive, but tend to get raspy with high gain settings.

Getting a 112 cab or baffle for your PR might be a nice idea as well. But it does not make the choice easier ...

Anyway, the Weber 10F150T sure has a lot of bass, so you might find yourself turning the bass down again (yet it should not sound muddy - but that depends on the cabinet as well).

hi damuniz!

the weber 10f150 or 10f125 are very, very loud speakers.
i wouldn´t recommend them for playing around the house.
i´d look for a vintage jensen 10" if i were looking for something to play around the house. they make the fender-tone we hear in our heads and they´re well-suited for lower volume-settings.

it´s entirely possible, though, that the sound you dislike in your current set-up comes from the amp rather than the speaker - like worn out tubes/caps etc.

i happen to own a ´79 pr myself and i´m using an oxford 10" of unknown vintage (codes are covered by the fender-label) - it sounds amazing ;)

cheers - C.

If you go 12" (I'd recommend it) all you need is a new baffle. The cabinet is big enough for a 12" and it is a very common mod.

I have a modded newer Jensen C12N in mine. Stock, it has icepick, piezo-like highs, especially with distortion, although clean tones can be glorious.

The piezo-like, strident highs are due to a hard paper dustcap. I cut the dustcap off (with a fresh Xacto knife) and replaced it with a felt dustcap (slightly larger than the original dustcap, which is small.

It's now my favorite speaker for a Fender. Nice, tight big bass, and plenty of clarity.

I have an old Altec 10" in another cabinet...huge magnet, aluminum dustcap. If my 65 PR had a 10" baffle, I'd put that puppy in.

Hi Carsten,

Are you referring to the 50W or the 25W for the Weber. I guess both would be pretty loud but I'd like it to break up earlier (25W) due to the low volume levels.

I agree, the tubes could be a bit weak. They appear to be original and as that might be a good thing to many people, I think they can wear out over time. I do hear some fizzy crackling noises periodically that is either tube related or speaker coil problems.
I'm looking at ordering some new tubes soon before I do a speaker swap.

Steve,
My 79 has the glued in baffle so a baffle swap would be a pain. Thinking I might stay with a 10" in the amp and maybe get a 12" extension cabinet.

I think I would take it to the guitar shop and play thru as many cabs as you can. That way you can see what you like.

hi damuniz!

i think i had the 25w-model of each in my ´79 pr. they were both loud and tight. too loud to ask for any sort of break-up at less-than-ear-splitting levels...

read the descriptions on the weber-site carefully (bright, aggressive, loud, very loud...) - they´re accurate ;-)

actually, i prefer the "cheap" jensen c10q reissue. it sounds sweeter to me...

but, like i said, i´d look for a vintage jensen if i needed another 10"...
but then - there´s so many choices today...


cheers - C.

Carsten,

You're right, too many choices.

I think I'm going to take your advice and look at a Jensen. Now it's down to alnico or ceramic.

I'm leaning towards alnico as I like a more rounded, warm tone than bright (which I find most ceramic speakers to be).

I'm going to retube the amp first and check the caps for drift first though.

Thanks to everyone who replied in helping me make this decision.

I've got a '74 SFPR with the fixed baffle and I sure as heck wouldn't mod that to fit a 12" speaker in there. Besides, I bought that amp because it's just perfect as-is with the 10" and I already had a SFVC (8") and other amps with 12s, so the PR fits perfectly in-between.

My amp came with an Oxford and I'm in the minority here that actually like the tone of that speaker. But, I took it out to preserve it and put in a Reverend 1030 when those were being discontinued. I must say that I like the Rev a lot more - and so does everybody else that's heard it. Never tried any Webers or anything else just because I can't afford that kind of experimentation anymore.
