Ceramic Thames 15

Weight: 11.6 lbs, Diameter: 15.125″, Depth: 6.31″, Cutout size: 13.75″


Impedance * 




15″, 60oz ceramic magnet, 80 watt, 2″ voice coil, ribbed cone. British bright, detailed, lots of punch, more headroom than the AlNiCo version.

Ted Weber Speakers are built with tighter, more concentric voice coil gaps, and lower carbon, machined steel parts in the magnet circuits which yield a stronger, more controlled tone at all volumes, particularly in the low end at high volumes.


Ted Weber Speakers are hand-built to order, to ensure the best attention to detail is paid to your speaker.  We build them one at a time, on a table – not hundreds at a time on an assembly line.  This allows us to reduce the margin for error and produce an overall higher-quality speaker.  Please allow 7-10 business days for your order to be built and then shipped.

    You better be in perfect tune and your amp had better be quiet when sitting idle, because this speaker tells all. It will reveal nuances that you didn’t even realize were there.

    This speaker responds excellent to EQing. It can be warm and round, or bright and piercing, and a mix of everything in between. Based on my clean EQ setting, it has a huge warm low end, piano-like lower mids, the upper mids are sweet and pronounced, and the highs are bright but rounded at their peaks.

    The only thing this speaker does not have is the sharp laser beam treble that emits from aluminum dust caps. The cap on the Thames is woven fabric, so the highs are smoothed out. Even still, the treble will split your ears if you don’t EQ it down a bit when playing at higher volumes.

    The Thames takes overdrive well. I like smooth but biting overdrive at the cusp of amp breakup, and this speaker does it well. The good sounding overdrive options are pretty limitless on this one.

    Sounds great at both low and high volumes. I placed this masterpiece into a Gift Reflector cab and hooked it up to an old solid state amp that I wanted to throw in the garbage. It is now my only amp, and it will not be replaced.

    I have a Ibanez Wholetone, 80w, 15" speaker, jazz amp (about $300.00 new). This amp was designed to stay 100% crystal clean and smooth with volume turned up to max, and it does exactly that. But, this amp was not pedal friendly and made a lot of horrible shrieking noises when I tried using them. In time the factory speaker also was not sounding as smooth and clean anymore. So, I tried some effects pedals. I have (1) Cry Bay 5350, (2) Rottweiler, (3) Black-13, (4) Metal Zone MT-2, (5) DS-1 Distortion, (Digitech RP50, (6) Big Muff (large box). I tried all of them, and the sound was very bad. The only pedal that sound fairly good was the Big Muff. This amp has a 15" 4 ohm speaker that had not markings of who made it (most likely Ibanez company). So, I bought the Weber 15" Thames speaker. The new speaker fit perfectly in the amp box with all screw holes. It took me only minutes to install, and when I cranked the amp up to max volume – Wow! It was so smooth and totally clean sounding with a warm rich bass tones. I then connected all the pedals listed here, and they all worked perfect with no horrible squealing noises. The Weber speaker really enhanced the over all clean tones, the clarity, and it is user friendly for all pedals. The Ibanez company does not make this amp anymore, but you may find one second hand in a music store, it will sound good (no pedals). But, the 15" Weber speaker will make it sound great with or without pedals.
