what is the amp?

what is the speaker in the amp and what is the speaker's impedance?

the technical needs of the speaker would require an appropriate impedance and power handling, this will depend on the amps specs.

in general 8 inch speakers are considered sub-optimal for guitar use. in particular people complain they sound 'tin-like', tight, and lack low-end. but there are definitely better speakers out there than others, depends on what you are looking for though.

i am unsure if i'd actually upgrade an 8 inch speaker. i'd be much more likely to maintain an old amp (like a supro or fender champ) by getting a new 8" speaker than to upgrade a more modern SS practice amp's speaker.

weber offers a variety of 8" speakers, usually modeled after older speakers from the 50's and 60's. celestion and eminence have one 8 inch speaker a piece.

^ yeah you don't have a ton of options for 8" speakers

I'll have to put the Classic T models on my to-try list. Shame the finish options there are Anachronism Gold, Nuclear Waste and Aged Clown, because in principle the plaintop is right up my alley.

the amp is a worthless ROYTEK 20Watt. but its my first one. the impendance is unknown.

run a DVOM across the terminal speaker in ohms (omega character) see what the number and it wil proably bea few ohms lower than what you have.

if i saw 14ohms for example you would want a 16ohm speaker.

gumbi really knows his shit. probably knows the most about speakers here on a regular basis.

There are several ways to polish a turd. I still have one of the very first headphone amps, modded with different value capacitors and a 9v clip to cut down on weight and expensive AA batteries. There's something about the tone and a couple of the effects that I can't reproduce with anything else.

Another idea would be to find or build a 1x12, 2x12, or even a 4x12 cabinet. as Mr. Trashed mentioned, you can use a multimeter set to ohms to find out the impedance. Most likely you will be able to run an 8 ohm load, which most guitar speakers are. There are plenty of used "vintage" speakers on ebay that will make any cheap amp sound better, just don't fall for the "vintage" prices - they were not worth that new.

hello, i measured 7,5 Ohms. I guess that 8 Ohm speaker would work well. I have a question. i didnt remove the speaker from the amp. so i measured the speaker soldered on the amp. is that ok?

I like my Jensen C8R. It handles everything pretty well at bedroom TV levels.
At higher volumes it's only good for clean and slightly overdriven tones, though.

Weber 8" are quality speakers that will make a sweet old tube amp sound sweet again. I'm not sure spending $80 on a Weber will help the Roytek much though. Is money better spent on a more musical small amp?
