    Anybody use them?

    I'm thinking of dropping one in my '65 Ampeg Reverberocket. I like the thought of increasing the volume and having a nice clear detailed low end.

    Nice tone, but significantly weaker sounding than a JBL IMO.

    I use one (with a paper dust cap) in my '54 Deluxe. It does what you'd expect: tightens-up the low end considerably, adds volume, and lets all of the Tweedy grindage come through, loud and clear. I've had it in that amp for about 7 or 8 years now, and have been very happy with it.

    Nice tone, but resulted in a significant drop in volume. *After* my purchase, I dug around on Weber's web site and found the following two plots: the first is the ceramic California with paper dome (what I had), while the second is the 12F150:

    1. http://www.webervst.com/spkrcalc/c12cap.htm
    2. http://www.webervst.com/spkrcalc/c12n.htm

    For what it's worth, notice the SPL of the Cali is 96db, while the SPL of the 12F150 (c12n) is 102: that's a huge difference.

    Thanks for your input, Dave.

    Ted has suggested a paper cone and a 'boosted' magnet ("We put a disk of neodymium on the tip of the pole which increases the sensitivity of the speaker.") - I'm wondering if going with the H-dome cone would be a good idea for this amp as well since it tends to be a little bright?

    Anybody ever get the H-dome option? Did it work out for you?

    Was this in a lower wattage amp? I'm wondering if those SPL disparities are more noticeable with a higher volume rig? I really have no idea - I'm relatively new to this speaker stuff.

    Thanks for the info!

    I have one in a late 50s Gibson GA40, and my experience with it is just as stated by Mr. Orban. The Cali has a certain amount of warmth, would match up well with a bright amp.

    Have been less than impressed with the JBL type Webers bought in the last year. I have one in my Twin that I purchased about 4 years ago, and it pairs very well with my D120F.

    I sent two of the recent purchases back to Ted, and he sent me a pair of Neos. Not much difference in thrust from the CA's, and a significant drop in volume from my JBL's.

    So based on the responses so far, it adds volume when used in a low wattage amp and drops volume when used with a higher wattage model?

    Oy.
