Speaker - Jensen® Vintage Ceramic, 8", C8R, 25W
The C8R is the little gem in the Jensen Vintage series. It delivers a solid compact tone that defies its size. Extremely versatile, it finds application in small home and student amplifiers; but with a microphone in front, it is capable of transferring on tape some of the biggest tones ever. Not by chance, the vintage Fender® Champ® amplifiers produced with the C8R speaker are treasured by many players as a great studio tool.
Guitarist Description: Crystal clear tone with brightly shining highs. Responds to overdrive distortion with a bright fuzz lead voice.
- Lows: Tight
- Mids: Aggressive
- Highs: Bright
- Overdrive: Edgy

Just placed this Jensen C8R in a 1959 Supro "Super"1606, replacing the original Rola. I wanted to keep the Rola safe for the future.
The C8R is a great choice for this 5 watt gem. I suggest this is one of the most suitable and cost effective speaker choices for this type of amp (Champ style).
There is a beautiful natural and warm break up. Delighted with the purchase! So much fun to play with this amp now. Thanks Amplified Parts!
Big improvement in tone for my 1980 SFVC. The speaker is better than the original and just popped right - no mods required. Highly recommend.
popped this into my 65 champ. PERFECT. exactly what i've been looking for tonewise. it just keeps getting better and better.
