hard to say, but that speaker could just as well be the best part of it

maybe think about a new mic-preamp for your guitar

Hi,

Yes well I clearly don't have any intimate experience with this driver.
For its price (23) it clearly has good build quality, and it has good
specs and a frequency response graph to boot, better than nothing.

You can always buy a driver with unknown specs and frequency
response, that some guy says he's bought and its "fantastic",
though he has no idea of the response or the likely matching
of the unknown driver parameters to the intended cabinet.

rgds, sreten.

Hi,

Not likely at all. Its a given that the speakers in most budget stuff
can easily be improved a lot by fitting half decent replacements.

I'd try an Eminence Alpha 8A. Known to be good for guitar and favored in small, high end Jazz amps.

Eminence Alpha-8A 8" PA Driver 290-401


Should work okay in your cab, probably wants about a 2" port.

Ahhh, very good and Yes, the cab has a factory cut 2" port

That's the ticket: 58Hz - 5KHz (covers drop D tuning), SPL 94db, 125W rms, one of the heavies @ 5.4 lbs must be built like a tank {8^D

I would have suggest that
but you might have to block the port with a foam plug
or else maybe the Beta8 would work with ported box


in any case, if ported, the box and port have to be 'recalculated' to avoid possible malfunction
but I really see no reason to use ported box at all

Hi,

The Alpha 8A is more an electric guitar type speaker, check its response.

At the same price the Celestion is more likely to work well, flatter response,
better parameters that will suit your cabinet more, and more excursion in
the bass end, and better built with its kevlar loaded cone and a weight of
5.1 to 4.3 lb, voice coil 1.75 to 1.5" and magnet weight of 31 to 20 oz.

YMMV but IMHO the Celestion TF0818 is a better bet, and a cooler brand.

For acoustic guitar you should foam line the back and sides of the cabinet.

rgds, sreten.

Port diameter is meaningless without also port depth and internal volume.
Give me those numbers and I'll simulate the bass end of the drivers.
Proper port tuning will determine handling of drop D tuning.

I only recommend the Alpha 8a because I play through two of them on a regular basis, and everyone that hears the amp is impressed with it.

FWIW, I prefer the clean sound of a Fishman Loudbox to the more colored sound of a Marshall acoustic amp. YMMV.


If you were recommending a Celestion Blue, V30, or Greenback, then I'd agree - they deserve their reputation. And I'm not a fan of the 12" Eminence guitar speakers. But just because Les Pauls are cool, it doesn't make everything Gibson has produced worthy. For that matter, they've managed to make some rather questionable Les Pauls.

Hi,

Not saying the Alpha 8A wouldn't work, just it and the TF0818 differ.

Neither is a bad choice, I think the Celestion is the better choice,
given that you can't compare them side by side in this application.

rgds, sreten.
