Following the heritage of the P12Q, the C12Q is one of the most versatile speakers in the Vintage range. Powerful enough for a cranked Deluxe-style amp yet balanced and warm, it surely is not lacking in bite. It has been used in both single and twin configurations by countless manufacturers including Fender®, Ampeg®, Silvertone® and Supro®, just to name a few.

Guitarist Description: Well rounded, straightforward tone with a lot of mid bite and bright highs.

By the 70's Fender was using Fender labeled speakers from a few different manufactures. The blackface Deluxe Reverb's came with Oxford's. The C12Q will be a great choice for your amp.

Hi. I'd settled on Jensen C12Q, 16 ohm speakers, after reading anything, and everything, I could find on the net. On a slight tangent, I had them on back order for a bit, at another place, before succumbing to frustration, finding them at the same best price, and in stock, at AmplifiedParts.com. They were shipped the same day as ordered. I love crisply new product, in virgin boxes. Amplified shipped my 4 new speakers, in their factory 2 packs. Couldn't have been happier with how it all looked after the 1000 mile journey. Back to the speakers ... I bought them, to be wired in parallel, for a 4 ohm impedance, to install in a Crate 412 slant back cabinet. This cabinet is from a notoriously impedance mismatched factory set up, with a Crate GT1200H amp. The amp head is 4 ohm impedance, the impotent, but sharp looking cabinet is 8 ohm. It's, at best, quiet. Others are more harsh in the criticism. By Crate's idiot design, the 120w head, is utilizing roughly 65w from the mismatch. Wire the new Jensens, holy crap. It was night and day better. The amp is really quite awesome now. These speakers have an excellent balance, and a nice tight sound. Crate really should be ashamed of themselves selling that matched product. Jensen, on the other hand, was a great answer to the problem. A great, Italian built product can be had here. The value for the price is nothing but outstanding. AmplifiedParts was pretty awesome too.
