Important Note
Watts: The guaranteed long term power rating throughout the usable frequency range of the speaker.
(Translation: the speaker will operate continuously at any frequency within the speakers specified frequency range when driven at this power. The "Watts" rating is similar to RMS, but is really more indicative of long term thermal capability.)
Music Program: The speaker will safely and reliably handle the varying frequencies of musical content at this power rating. The "Music Program" rating is more indicative of what you can expect in the real world with the speaker operating within the appropriate enclosure reproducing music or vocal audio program.

Eminence Private Jack Red Coat Guitar Speaker (50 Watts, 12 in.) Reviews

"The Private Jack likes to play in the dirt!"
Quality:
It's an Eminence...enough said!
Value:
Zzounds had by far the best price around. Not to mention the free shipping. Thanks guys.
Sound:
This speaker is particularly well suited to give you that classic dirty low down raunchy tone. If that is the tone you want to achieve, then this is the speaker for you. From blues to classic rock and heavy metal and grunge, this speaker shines.
Overall:
I can only compare this speaker to the one's it replaced. The Eminence Private Jack's I purchased replaced the Celestion Seventy 80's I had in my Traynor YCV-80 combo amp. The Private Jack's made a huge improvement in the tone of my amp. Gone now are the shrill ice pick highs (ouch)I had with the Seventy 80's and the bottom end is much more smooth. The Private Jack breaks up a little early in my opinion; so if you want the classic clean tone, you might want to try something else.

"Stop being a Celestion snob and get a speaker that wil do your amp and ears justice!"
Desirability:
The "red" color of the speaker makes it stand out impressively
Sound:
I had this speaker in a vintage Alamo Montclair combo amp. The tone is phenomenal. I could actually hear the difference, unlike the Celestion I had intalled in my Pignose G60R. I don't know if it improved the sound or not.
Support:
Have not had to contact company
