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.

"Opened Up My Dark Amp"

Overall: 5 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I have a 2006 Gibson GA20-RVT which is a very dark amp that lacks depth that comes with higher frequency overtones. The stock speaker is a lower end Eminence. I tried a Jensen Alnico and Celestion G12 50th anniversary. Neither of those worked for me, so I did some reading and research on the internet. The Eminence Red Coat Private Jack looked like it might fit the bill so I ordered it. After installing it in my amp the deference was immediately noticeable. The higher frequencies were more pronounced and smooth, adding much needed depth to the tone of the amp. The overdrive is also more smooth and pleasing. I've been using the speaker for around 20 hours now and I think the sound has improved as the speaker breaks in. If this speaker came in the Gibson GA20-RVT this amp might be more well known and sought after. It is a different amp now.
