Hemp cone! Replaces Chicago Jensen P12Q and other medium power AlNiCo 12’s where a warm top end is desired.

12″, 11oz AlNiCo magnet, 20 or 30 watts, 1-1/4″ voice coil, hemp ribbed cone. This speaker has a warm tone, not too bassy but a good balance throughout. Top end is mellow and the attack is less immediate than other speakers due to the hemp cone. Hemp’s longer fibers give treble notes a sub-harmonic richness that warms the sound. Compressed and fattened at higher volumes.

• What’s Dope?

• What’s an H dustcap?

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.

    I purchased this speaker (8-ohm, 20W, H-dustcap, moderate doping) for a customer who plays bluesharp. He had one of those nifty Epiphone Electar 75th Anniversary Century amps and asked me to make it a "tone monster." A fresh set of carefully selected tubes, a repaired bias pot, and a serious speaker upgrade gave him exactly what he was looking for. It sounded awesome when I tested it with a strat, but my customer really made it sing with the harmonica.

    Out of everything, I have to give the most credit to this speaker. The hemp cone provided the warmer tone he needed and the H-dustcap did exactly what it was designed to do: cut the harsh frequencies that harmonicas can create and emphasize a tonal sweet-spot. I am certain that the AlNiCo magnet did it’s part to deliver more warmth and natural compression than the stock ceramic-magnet speaker. And finally, choosing the lower power rating allowed the speaker to be more fully used by this 15-ish watt amp than the stock 30W speaker. The hardest part was getting it to fit in the cab with the chassis and the back panel; there may have been 1/8" clearance between the bell cover and the back panel, but it worked!

    Before this overhaul, my customer had trouble getting the amp past 6 (out of 12) without terrible feedback (using a Shure Green Bullet mic). After the work, he was getting it up to 9 with an amazing volume and tone.

    I highly recommend this speaker and will definitely be considering it for future projects!

    I used this model to upgrade from a 12" VHT Chromeback in my VHT 12/20 Special. Much more musical with an overall smooth delivery.

    I got one of these for my Allen Hot Fudge w/Nuts (6G3 style amp) and it sounds phenomenal! Crunches up fairly easily and compliments the amp well. Well made and reasonably priced too.

    this is my first venture into a hemp cone speaker….mine is 30 watt, H dustcap light dope…

    I installed mine in a 1960 Gibson Ga-30..its matched with an 8" Weber 8A125 20 watt, H dustcap, light dope….
    It replaced a Weber 25 watt 12A150T with same dope and dustcap…
    the amp has a tone selector switch that cuts the high frequencies/boosts the lower frequencies…..
    the 12A150T has a bit more treble bite to it, and a bit looser on the bottom end…not bad, but I got bored and decided to experiment…..I removed it and put it in my 1958 Ga-20 and it’s perfect for it…
    The hemp cone makes a noticeable difference in the amps character and break up….even though I’m not even close to it being broken in, its a bit warmer overall, tighter on the bottom and more refined highs…it’s a perfect fit for this amp…..and the tone kills with a telecaster…..even the ones with original Seth Lover Humbuckers…

    Sounds great with just a compressor…and of course a nice OD pedal will make it sound even better.
    this is a great speaker choice for an amp that has piercing treble and loose on the bottom end.

    After its’ broken in I’ll re post if my opinion changes…
