Celestion F12M-150 Triple Cone

An incredible speaker. I almost got rid of my Digitech RP-1000. I had it for years and the presets and total sound was getting old and boring. I heard about these series of speakers that are specially manufactured for multi effects. They don't color your sound and the preset with amp, cab and effects sounds similar to the original. Installation was pretty simple and after 10 minutes I was connected. At first, all of my presets sounded horrible. I realized that I had to tweak them to fit the new speaker. So, after some tweaking and exploring... Oh mama. What a difference. It's like having a brand-new library of sounds at my disposal. It made my Marshall MG50DFX sound like everything: classic rock, texas blues, metal, fusion, funk, punk and so on. This is a must have purchase for any player that uses a multi effect for designing their sound.
And of-course Thomann, thank you for the quick and excellent shipping.

So I bought this to use with a FRLR cabinet with my Kemper. A great project which I'm (still) quite proud of. However it's lead to a number of other projects because of how unhappy it has left me with regards to my bass tone. Eventually I've come to the conclusion that the F12M-150 might be the culprit. Most FRFR speakers go down to 52Hz which is still a lot higher than 41 needed for a low E on the bass. This (though clearly stated) has a much higher lower bound at 60Hz. I bought the modeller because, just like many of my dual guitar and bass playing colleagues, then I don't need one cab for bass and one for guitar.

Great for guitar. Useless for bass. Need to build a whole new cab.
