I’m including my audio pages on this website instead of having them on a separate website. My audio work can now be found at idealfuturevisioin.com instead of aumacoustics.com.
This change will take some time, but I should be done by the end of March 2025. Sound is fundamental to elevating consciousness to the highest level, and the work I’ve done over the decades is part of this effort. Now, I’m including both with one website name, and that will be how I deal with both efforts in the future.
Merging both websites makes a huge difference and should benefit you immensely, even though the two areas might not appear connected initially. They are.
Aum Acoustics is going through a complete redo, so please be patient. The speakers, the DAC (as the source), and the amp are currently undergoing experimentation. I’m doing this because the last build I did worked out even better than Voxativ Hagen’s on top of a pair of 12″ open baffle bass speakers I purchased from Closer Acoustics.
I no longer recommend using either the Voxativ driver or the Closer Acoustics open baffle bass since the new speakers are even better (with my tuning approach) and my speakers are much lower in cost. They use a 15″ coax and an 18″ bass driver, and both are open baffle by design. The sound quality is stunning. The speakers are 20″ wide by 36″ tall. They sound much better than a slimmer speaker and work well in a near-field position and mid and far-field work. If you keep your system simple enough, you can flank a workstation with these speakers. I do it, and so can you. More about that later.
Using this size speaker is almost required to get the ultimate sound quality from an audio reproduction system, and these speakers and components only cost around $2,000 if you build or have built the open baffle method to hold them. How they look is up to you and can be crude or well done—your choice. The sound quality won’t vary, and only the appearance will. So, this approach will provide an affordable means to acquire a system like this. I’ll explore how you can use excellent sounding components to maximize their sound and give a much lower cost than only recommending the higher-priced system I’m using.
With open baffle speakers, your room is your “cabinet.” The speakers play to the high 20Hz region and up to maybe 18Khz. This design can be improved, but it will take a much larger speaker and even more money. This is the best that can be accomplished with a lifestyle-oriented speaker and doesn’t require that you sit with your head in a vise in a single listening position.
The speakers I am building into the final pair are even better and more efficient. They work exceptionally well with an EL84 push-pull tube amplifier and will be efficient at 97 or as high as 99 dB. So, they will work well with a tube amp that puts out 6 to 8 watts per channel. A solid-state amp lacks the body and emotional pull to listen to music, and a tube amp does. I only recommend using a tube amp with these speakers.
The big difference between the two amps that I’m using is that the EL84-based one (17 w/ch) has a push-pull design, while the 300B Western Electric Telefunken 3CM input tube-based amp is single-ended and puts out maybe 6 w/ch. Power is not a problem with these speakers; either amp will work well. However, from my own building experience, a single-ended amp sounds better than a push-pull amp, but I need the one I have being built here to determine if that’s true for this build. Time will tell.
I purchased my EL84 amplifier from Amps and Sound (their Little Nugget). However, I have a 300B amp built by Treehaus and Radu Tarta, and this amp might just be even better. It is expensive in comparison ($16,000 versus $6,000). I’ll let you know if it’s worth the expenditure. If not, the EL84 amp has undergone complete tuning and will be the approach I use. However, I have my eyes on a few EL84-style amps and might change from using the Little Nugget. Again, time will tell.
Stay tuned for the work I’m now doing on this website.
