copypasteninja<p>Ordered a bipolar SMPS for my DIY F6 amp from Connex (SMPS300RE). Turns out the negative rail is 1V beneath the positive. The answer from the supplier (audiophonics): in spec. I don't think so but maybe I'm wrong.<br>Next try is with two SMPS from Mean Well connected toghether to create the bipolar power supply. <a href="https://norden.social/tags/DIYAudio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DIYAudio</span></a> <a href="https://norden.social/tags/powersupplies" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>powersupplies</span></a></p>
bgrier 🇨🇦 🍁<p>Update and final thoughts - Refoaming dbPlus 440 Speaker Surrounds<br>1. Initial Condition</p><p>The dbPlus 440 speakers were in poor condition before the refoaming process. The foam surrounds were cracked, crumbling, and in some areas, entirely missing. The cabinets, while aged, remained structurally sound and only required minor dusting. Notably, extra screw holes were found on the driver mounts, indicating that the drivers had been remounted at some point. Since both speakers were a matched set, it is unclear whether the drivers were replaced during manufacturing or in a later repair. <a href="https://universeodon.com/tags/VintageSpeakers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>VintageSpeakers</span></a> <a href="https://universeodon.com/tags/AudioRestoration" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AudioRestoration</span></a> <a href="https://universeodon.com/tags/DIYAudio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DIYAudio</span></a> <a href="https://universeodon.com/tags/Audiophile" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Audiophile</span></a> <a href="https://universeodon.com/tags/3dPrinting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>3dPrinting</span></a> [1/5]</p>

Ian.Burnette<p>I completed these a while ago, but never got around to bragging (well, not online at least). Two wall mounted DML panel speakers finished with walnut veneer and brass foil. If only I could figure out how to do this instead of my day job 😅 <a href="https://toot.community/tags/woodworking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>woodworking</span></a> <a href="https://toot.community/tags/DIYAudio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DIYAudio</span></a> <a href="https://toot.community/tags/DIYSpeaker" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DIYSpeaker</span></a> <a href="https://toot.community/tags/speakers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>speakers</span></a></p>

Daniel Marks<p>Over the <a href="https://mastodon.social/tags/pandemic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>pandemic</span></a>, I designed my own stereo system including an <a href="https://mastodon.social/tags/audio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>audio</span></a> amplifier with well documented instructions. It is a simple class AB design, 300W per channel, THD &lt; %0.01, balanced input with extensive protection circuits and has been perfected through five revisions. It has a nice clean, powerful sound that easily drives low impedance speakers. It has great component substitution flexibility. I use it every day.</p><p><a href="https://www.github.com/profdc9/PowerAmpAudio" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">github.com/profdc9/PowerAmpAud</span><span class="invisible">io</span></a></p><p><a href="https://mastodon.social/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>electronics</span></a> <a href="https://mastodon.social/tags/audiophile" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>audiophile</span></a> <a href="https://mastodon.social/tags/diyaudio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>diyaudio</span></a> <a href="https://mastodon.social/tags/sound" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>sound</span></a></p>

Olem<p>Phew, got them done in time. Finally finished my DIY Wolf's PC-speakers. Gave the oak boxes plenty of boiled linseed oil and generous coat of shellack, and then rubbed them down with steel wool to get a satin sheen. Worked out well, as that stuff always do. The Aurasound NS3-8 drivers are in, and now I'll play them in for a bit, before I wrap them and give'em away. Fun project, hope a special someone will be happy.

amd<p>Got these printed speakers assembled today. </p><p>They’re nice compact units that fit well on my desk and they sound pretty good to my non-audiophile ear. </p><p>If I was going to use them as my primary listening devices I might want to print Hexibase’s subwoofer design but I think for my purposes these will work great. </p><p><a href="https://www.printables.com/model/190787-hexibox-series-tectonic-tebm28c10-4a-micro-t-line" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">printables.com/model/190787-he</span><span class="invisible">xibox-series-tectonic-tebm28c10-4a-micro-t-line</span></a></p><p> <a href="https://social.amd.im/tags/3DPrinting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>3DPrinting</span></a> <span class="h-card" translate="no"><a href="https://techhub.social/@3dprinting" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>3dprinting</span></a></span> <a href="https://social.amd.im/tags/DIYAudio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DIYAudio</span></a></p>
