    Silk Purse out of a Pig's Ear? Flint's new coaxial speaker design

    Thanks!!! I wish I had customers who felt the same way.

    Silk Purse out of a Pig's Ear? Flint's new coaxial speaker design

    With this project I chose to use cheap digital amps, but very modern ones using the latest ICs from TI. Over the past year I have built many speaker systems which were not meant to be truly audiophile quality and thus mating them to affordable and small digital amps was an easy choice. As I...

    Silk Purse out of a Pig's Ear? Flint's new coaxial speaker design

    By the way, saving money on ingredients doesn't really cut the real costs if one considered manhours. While using a scrap piece of 1/8" plywood saves me from buying $30 worth of high end binding posts that can go straight through MDF, mounting those expensive binding posts is as simple as...

    Silk Purse out of a Pig's Ear? Flint's new coaxial speaker design

    In all, I didn't spend much money (I had the MDF in the shop and the paint, amps & crossover were the only cost, really). The results, from what I've auditioned so far, is amazing. They are clear, clean, tight, and smooth with loads of detail and lots more bass than I anticipated hearing. It is...

    From the primary listening / watching seat. I think they look very nice. Here are the measured in-room frequency response curves of the two speakers after tuning. The bass extension is both measureably and audibly very solid and low for a small 6" mid/woofer. I am very pleased. The right...

    Mounted and running on the stand and placed where I intend to keep it. At an angle.

    Silk Purse out of a Pig's Ear? Flint's new coaxial speaker design

    I never liked the metal stands I had the MBS01 speakers on, so I used the cutoff pieces from the angled tops of the "Rocketman" loudspeakers and made stands for the new speakers. I sealed the MDF where it would be visible and painted the stands a dark brown which I thought looked good with...

    Silk Purse out of a Pig's Ear? Flint's new coaxial speaker design

    I decided to use cheap Walmart purchased polyfill to stuff the enclosures to save on costs. It took a bit more than would be need if I used Acoustastuff or fiberglass, but it still costs less than half. Getting ready to mount the speakers. Since the tweeter can be delicate, I installed a...

    Silk Purse out of a Pig's Ear? Flint's new coaxial speaker design

    I spot painted some orange and lighter yellow on the front, then draped yarn and twine over that before painting with the Sun Yellow again which made some stringy lines running vertically. You can sorta see the pattern here. It doesn't photograph well, but it looks very nice in person. I then...

    Silk Purse out of a Pig's Ear? Flint's new coaxial speaker design

    Once the baffles and enclosures were assembled, I sealed and sanded many times to get a smooth, surface all around which can easily be painted any color. This was the most time consuming part of the build, though the difficulty was low. I then glued the baffles to the enclosures and painted...

    Silk Purse out of a Pig's Ear? Flint's new coaxial speaker design

    Dry fit of the whole enclosure from the front which will be glued onto the baffle. The extra holes on the front reduce weight, increase internal volume, reduce vibration, and break up reflections. The two baffles after fully shaping. I use four short dowels to align the enclosures to the...

    Silk Purse out of a Pig's Ear? Flint's new coaxial speaker design

    All the parts laid out for one enclosure with the parts for the second enclosure stacked next to them. Dry fit of the folded vent for the bass loading. Note that I used concave rounded strips made from cheap PVC crown molding to soften the corners which vastly reduces resistance at the folds...

    Silk Purse out of a Pig's Ear? Flint's new coaxial speaker design

    I decided to replace the amps I was using with smaller, less costly models. I chose to go with small digital amps from Parts Express and an affordable DSP crossover. In total, I spent less than $200 to replace two mono amps for which I originally paid $250 each (or $500 for the pair). Mini...

    Silk Purse out of a Pig's Ear? Flint's new coaxial speaker design

    I am in a position where I could benefit from selling stuff and since I own so much audio gear, I am looking into that. Recently I worked on a project for a partner using some coaxial speakers and thought they were amazing, especially for the price. As it turned out, the first two speaker the...

    Curious about your thoughts - speaker exciters

    I am extremely intrigued by these. I know they are not high fidelity by any means - so don't expect to see these replacing a good set of speakers. However, if one is considering a typical TV sound bar, I'd seriously think about making two large panels, perhaps with a movie poster or art...
