Hey amp heads

I have a question for the masses.
I have a small combo amp (DSL15) with 16 & 8 ohm speaker outs.
Stock speaker is a 12" 16ohm . Want to try a different speaker.

My question is will an 8 ohm speaker in an 8 ohm speaker out sound the same as the same 16 ohm speaker
in the 16 ohm out?

The reason I ask is I have a 3 different 12" 8 ohm speakers here.
Instead of buying a 16 ohm speaker, could I just stuff an 8 ohm Vintage 30 in there using the 8 ohm jack
& be done with it, or is there special mojo magic with the 16 ohm out in Marshalls?

Any and all opinions will be appreciated.
 
Alright...
A different speaker model will sound different.
The same model in 8Ohm plugged into the 8Ohm out should sound about the same...just might show a difference in age of speakers, if any.
The disadvantage of using an 8Ohm in the proposed set up is that the possibility of using an external speaker cabinet is eliminated (unless there is a 4Ohm output that was not mentioned).
Otherwise, yeah...jam that V30 in there and see how you like it.
 
Grooviness, thanks Don.
The amp has three outs, a 16 ohm & two 8ohm.
So it looks like I'll be doing some speaker swappin'.

Just didn't want to freak the output transformer out.
 
I actually Do Mr Hack .......
They list is as "Electric BLue" I think --- but it looks purple to me :)

Good question. I've thought about this, too. The best way to find out, is to have the identical speakers, but one at 8 ohms. Also assuming that both speakers are broken in!

Another option is to use an impedance matching gadget like my Weber Z Matcher. With this gadget in your scenario, you can plug into the amps 16 ohm output and connect to an 8 ohm speaker, safely. Hell, you can connect to a 2 ohm speaker, and do it safely. Or... vice versa: Connect to amps 8 ohm output, and then connect to a 16 ohm speaker (Or whatever other ohm speaker).

Weber builds a 50 watt and a 100 watt impedance matcher:

GREAT product!
 
Very interesting. Thanks for the input guys.
I'd love to try a Greenback. Sir Goldie has never steered me wrong, but I'm trying to avoid another speaker purchase and already have a Vintage 30 stashed.

OOOHHH I like it!
 
Be sure to put them in the threads you start about them -- "tag" them -- that helps the GOOGLE SPIDERS find them --- and that is always good -- unless you just committed a triple murder and a goat sacrifice before brunch -- -- then spider finding would be BAD

Just didn't want to freak the output transformer out.

Out of curiosity, I took a quick look at the manual on the DSL15C.
It looks like the way the outputs are set up is as follows:
Stock speaker plugged in to 16Ohm jack=normal function of stock 16Ohm speaker.
If you want to use an extension cab that is 16Ohm as well...
Plugging the extension cab in to an 8Ohm jack, while the stock speaker is plugged in to the 16Ohm jack, defeats/shuts off the stock speaker.
If you want to run the stock 16Ohm speaker while running a 16Ohm extension cab-both at once-plug the stock 16Ohm in to one of the two 8Ohm jacks, and the 16Ohm extension cab in to the second of the two 8Ohm jacks.(the output transformer sees an 8Ohm load in this scenario)
There is no provision for any combination totaling any impedances other than 8 or 16 Ohm.
