- I heard the speaker at an Audio Show and also at several other peoples homes who had built it and was very impressed by the Super 12's! They had a wonderful Tonality and Effortless played not just the notes but more as a whole - as Music. They had great color and Dynamics too, and I had really intended on building them but never had the room for the extra set of speakers in the living room, and never got the dedicated music room either... So I decided they deserved to built and enjoyed by someone! They are an easy straight forward to build speaker, that only need basic skills to complete, but play much better than you would expect.

* Here is a Quote from the original designer of the speaker John Wyckoff
--
"The mission of Hammer Dynamics is to create great sounding, well balanced, high-sensitivity loudspeakers, to owners of low powered tube amps, for reasonable prices. Five years ago I was struck by the fact that there were no inexpensive high-efficiency loudspeakers on the market. Once I settled on a "full-range" approach I began testing most of the full-range drivers on the market. Not one of them gave me the sound I wanted no matter the price. The few, which had reasonable mids and highs, had no bass. The few, which had good bass, had lumpy mids and no highs. My solution to these problems was to design my own driver. My final design represents the best compromise I have been able to come to. The driver is capable of fast, accurate bass, silken mids and exceptional response to 10,000 Hz. I believe it is better to add a fast super-tweeter to a system than a slow sub-woofer. During my research I found that the usual 8-inch full-range drivers were never going to offer the kind of dynamic range I wanted so I finally settled on an ultra-light 12-inch. The entire moving mass of this driver is less than 29 grams. With a surface area of around three times that of an eight-inch driver the dynamic range is increased by a similar factor. The S-12 represents my efforts to create a loudspeaker that sounds like Quad ESLs with much greater dynamic range, sensitivity and another octave on the bass-end."

- This is a Custom made Speaker Driver that was the life's work of John Wyckoff , John spent five years designing working with this speaker driver perfecting it!
-- "The Hammer dynamics Super 12 Speaker Kit is a great opportunity for someone to build a very special speaker that offers outstanding performance , but also one that really anyone could put together, the great thing about this kit is that with a minimum of time and effort it will show you that the Super-12's can recreate vocals, percussion, strings, and wind instruments with startling reality. All the great jazz vocalists that I love sound incredibly natural: Nat King Cole, Sarah Vaughan, Sinatra, DeeDee Bridgewater, etc , and the Super 12's can rock out too if that mood strikes you, they have some of the best bass most have ever heard from a Full Range driver!"

- The Super 12 Speaker is a pretty straight forward design - ( basically a rectangular box), the outside of the box can be modified if desired for your own aesthetics, but the inside should remain the same. - In order to get the best out of it I really recommend Reading the directions carefully first - John took a long time to make sure he was getting the most out of this custom modified driver design .... ( usually what happens when people end up not following John's plans and trying to modify it first... well, the results can be less than the outstanding sound you were expecting ... But if you follow the directions -- Outstanding Sound will be your reward! - Then If you want to change something you will have a baseline and know how good it was designed to sound. ----
-- There was a website that was specifically set up for the discussion of Full Range drivers and Speakers, and had a section just for this Speakers design and also the modifications that others had tried - Unfortunately the website has been taken down..... I do have a copy of the Mods section and if you would like I will include them.

-- The above pictures are just a few Examples of how you could choose to finish your kit, they can be painted, either by roller or Spray painted, or veneered.... or you can simply Stain the wood & poly coat the speakers, Etc. , you are only limited by your imagination! Others have even used fabric or leather, and a few even used Truck Bed Liner Paint, which has a very durable surface, and can look nice as well. - The last picture is a modified version of the speaker using the Fostex FT-17H Tweeter.

Check out what famous reviewers and satisfied customers think of these speakers! --- Dick Olsher, reviewer, Enjoy the Music.com™: The feeling of effortlessness and purity in elucidating the music's tapestry is precisely why I so thoroughly enjoy this speaker.The deep bass is extended to about 40 Hz., while the midbass sounds tight and detailed. This represents a quantum leap in performance over my anemic Lowther PM2A rear-loaded horn.The Super 12 loudspeaker joins a select group of speakers that I could enjoy until the end of time. ---
Yeo Chiau-Woon, DIY Paradise: Kudos to Hammer Dynamics for coming up with such a great product. Affordable, great sounding, high sensitivity. And also for the excellent support/customer service, second to none. ---
Tim Adams, audiophile: The speakers just disappear to be replaced by a sound-stage that starts near my back wall on most recordings…And goes back …Wayyy back. And wide. Excellent focus and Detail. Good Tonality- Bass is fast, Focused and Deep. A wonderful sense that I am hearing the music that the guy on the sound board was hearing. As for vocal improvement . . .last night I discovered that Elvis is in the building - mine. ---
Gregg Roberts, audiophile: They make beautiful music! The sound is very nice, with real power, bass and dynamics. The sound stage is wide and deep, and well focused in the middle.Vocalists are sometimes in the room with you. I think the bass is the best I have heard from any speaker at any price. ---
Bob Hedberg, audiophile: These speakers are in a league of their own. They have incredible dynamic range, are very sensitive, and provide a satisfying range of music from 40 hz up past 20 khz. Voices have real "presence", and can be a bit startling at times. They also look very good, and the kit is easy to build, and works well. I used birch ply, and finished them in red mahogany. I do recommend putting a brace from side to side, centered internally, which stiffens them up considerably. They also do have a long break-in period, which must be observed before critical listening. ---
JP, audiophile: They are like electrostatic headphones for your room! ---
Joseph Santor, audiophile: These things sound like real music in front of you The Midrange resolution is truly stunning ---
------ John Wyckoff , Designer John spent five years on this design before releasing it for sale. You may have noticed me mixing my tenses. John past tense, speakers present tense. That is because John Wyckoff sadly passed away, still a young man... John was very friendly man and super helpful.... He will be sorely missed in the Audio community. - - -
- "How did I find out about the Super 12? Ian has a pair. Thank you again, Ian. I'll post later about my experience listening to this system if anyone is interested.For now I will just say how much I am enjoying these speakers! Clark , Dukatista47
