I decided to swap one of the Vaporizer stock speakers. It instantly blew my mind. Those who own the amp, will know that it can sound very "boxy" and harsh. After reading about a lot of mods people do, I decided to go with the speaker swap which is the simplest one.
Instant tone improvement. The cleans are beautiful, the amp break-up is much better. Throw a heavy OD pedal in front and you can go full on AC/DC. Tested with a Strat and an Ibanez RG in various settings, both channels. This speaker really does the job. This specific amp is now far more gigable (thanks 2020).
However I must say that I think two of these on a Vaporizer would make it too chimey. In my case, it added whatever was missing from my amp and interacts well with the stock speaker. If I ever wanted to replace the other stock speaker, I would go for something with more bass probably. Consider that if you intent to use it on this amp.
The speaker is of excellent quality, the boxing seems to have protected it from all the transporting. Would definitely recommend.
