2. Size and Weight: Due to its large size and heavy weight, this speaker may require significant space and support to be set up and used effectively. This could be a concern for those with limited space or mobility issues.
3. Complex Setup: The use of dual voice coils and advanced features like bi-amping or bi-wiring can make the setup process more complicated compared to standard speakers. This may require additional time, expertise, and resources.
Conclusion:The Hempopotamus 30Hz/SA 12 Alnico speaker with dual voice coils offers exceptional bass response, rich sound quality, and flexible configuration options. However, its high cost, size, and weight, as well as the complexity of its setup, may not be suitable for all audio enthusiasts.
Recommendation:If you are looking for a powerful, high-end speaker that can deliver deep, rich bass and clear, detailed sound, the Hempopotamus 30Hz/SA 12 Alnico speaker with dual voice coils is an excellent choice. However, carefully consider the costs, space requirements, and setup complexity before making a purchase. For those on a tighter budget or with limited space, there may be other speakers that better suit their needs.
Details:
Yep- that's what I thought. This 1960s gem was stripped down to bare metal and magnet, then everything replaced. From the inside out, its basically a new speaker again only better. And as mentioned, I used color coded heat shrink insulation on all lit wires so they can't short out.
This stuff really dampens the frame ringing to almost nothing. So, by applying this coating to the stamped steel frame, its dampened, and sound you hear is pure accurate, without secondary ghost notes being reflected into your. LTZ wires these are copper lit wires. Stronger and lighter are the way you want to go for perfect cone.
There are no after market, replacement, or import China crap in it, but only American made parts. That gray stuff does nothing but smudge and smear the signal before it even gets to your voice coil. So, after being stripped down to bare metal and magnet, then coating it with that textured finish the build process began, theres a few really cool things bring up this one. The frame was stripped down, and then shot with that granite textured, multiple colored gray poly finish, so it looks feels like stone the beautiful thing I found out by accident.
Magnetic composition alnico vii. This really lowers moving mass, and aids in speed, detail resolution. Get comfortable guys this is gonna' be another one of my long ones. This unit really is greater than the sum of its parts.
But- mother nature and physics don't care about the application ringing is ringing, that energy gets re-radiated into air via your cone, or even baffle board. I'll itemize the components. Surround this is also a hemp fiber material, as its part of the molded cone assembly. The Hempopotamus hemp fiber cones.
Front gaskets I found a set of old oem natural/tan gaskets with the 4/8 hole mounting pattern, so used these for cosmetic appearances. Some people say these old oem magnetic assemblies sweeten with age, and after I heard it, have to agree. Heres where this gets interesting. Take a pencil, fork, screw driver, or anything you can find, and tap onto your speaker frame.
Frame- stamped steel dampened 4 spoke frame. By using copper you get true signal transference to the coils, and your tonality will show it. Which is physically impossible but this a huge step in that direction compared to anything else out there. I can't really add anything constructive to the i've already typed.
Is Oz! a big factor that people usually overlook unless they are doing high end hi-fie. I also placed heat shrink/ high flexibility insulators over the lit wires, and bonded them on each end to prevent any movement or possibility of vibrations. I found a number of voice coils, that are not bass/sub woofer but rather dual winding/ fine winding wire, full range light weight design perfect for this application. It should be infinitely light and stiff.
Its black, although lighting makes it appear slightly blue. Up for grabs is this tremendous sounding 12 alnico brass sleeve hemp fiber cone speaker multiple impedance's guitar. The magnetic gap was verified with a Gauss/flux probe and measured just fine, so it purposely not de-magnetized/ re-magnetized. And just for fun while I was at it.
Talk about versatility, this one does it all. This was lightly treated with rezone-ex in order to prevent any cone edge resonance issues, and omit secondary or ghost-notes from being reflected back into the cone, air. Any questions or concerns, just ask. The cone profile is straight/conical, and a ribbed body to help dispersion angles at higher frequencies.
Fully tested under diagnostics and operates without any rubbing, smoking, buzzing, holes, rips, or tears its basically a brand new speaker only better. It was treated with special Eastman Kodak chemicals to loosen the fibers in that area only, and aids low frequency response.
