I thought it would be fun to share a set of very high end loudspeakers I designed and built nearly 3 years ago. The goal was to make them simple unique in appearance and fully integrated to the base/stands the way the original Energy loudspeaker from the 1980s was built. I always envied that...

Something like this, but the material would be the same gray color as the lower strip:

MDF is merely sawdust with a weak resin in it to lightly hold it together then compressed significantly until the resin cures. It is NOT a structural martial which is capable of being fastened through the edge and being fastened into the face is not very strong at all. It isn't intended for use...

Hmmm.... it is hard to explain as this is an area of expertise for me. So what makes me an expert in this area? I've worked with all of the Tweeters currently on the market selling for over $250 each, even these, and they are not dramatically different tweeters from the dozens of other Supreme...

BAH! I eat MDF sawdust as porridge and sprinkle it over my salads and pizzas. Real men wear it in their eyes and their nostrils as a badge of honor!

This past weekend I finally installed some acoustic absorbers on the wall under my TV which is behind my loudspeakers. For many years I had used three 2 x 2 foot foam wedge sheets just stuffed into place in that area, and while they functioned fine, they would slip around and were rarely...

I am anxious at the breakneck pace Heeman is taking at completing these speakers.

These are NOT Wilson Audio knock-offs. Using odd-shaped enclosures to control internal reflections and standing waves goes back to the 50's and is common today in nearly all high-end loudspeakers, including the C1s these will be replacing. This design was intended to be easy enough for Heeman to...

As for making choices, everything has to work together, and every choice impacts every other choice. Drivers need to work well together. The baffle has to work ideally for the tweeter's forward propagation and provide reasonable area for all the drivers, how the drivers fit on the baffle is...

These cutting-edge midrange drivers are the latest and most advanced low distortion drivers with stunning dynamics for their size. You will not find a better midrange driver for true high-fidelity reproduction that this model without spending nearly double the price, and there are only a couple...

MDF is often the choice for loudspeaker enclosures because of the commonly available materials, it exhibits the best acoustic performance. It is self-dampened, the resonances are at higher frequencies due to the high mass per volume, and it is harder to excite into resonating than hard woods or...

Fasteners weaken MDF joints and not recommended, ever. I've built thousands of enclosures from MDF using only glue and not a single one has ever failed at the joint. In fact, when I would test how they would fail, I managed to get dozens of unused enclosures (mostly prototypes and leftovers)...

You should all be insanely envious of what Heeman is building. These will rival $50,000 systems when completed and tuned up.

My amazing, but 8 year old, Topping VX-1 amplifier with USB digital audio amplifier died a few days ago, so I needed a solution for my office rig. So, I decided to experiment with budget stuff. I'd seen these for awhile on various sites and decided to give it a chance. It is a cheap, Chinese...
