        "content_html": "<p>While at Axpona, I had enough time to discuss the speaker design and goals with Neil. I have started to understand the Mass Loaded Transmission Line speakers better. I do not understand the math, so I will not delve too deep into that. The goal and the result are a smaller speaker with better low-bass response and a very smooth and detailed midrange.</p>\n<p>Cutting the cabinets on a CNC machine allows for much greater precision in construction, ensuring that the transmission line is “perfect”. The design uses 4in drivers that have very low moving mass to improve mid-range performance.</p>\n<p>The series crossover is adaptable to many levels of performance.   With the help of Neil and a local expert on crossovers, I have selected and optimized a set of components that should be a “BEST++” with just a bit more expense. I use Duelund bypass capacitors and a Duelund resistor in the tweeter circuit.   Goertz flat copper wound inductors are a bit more expensive, but I am sure they will be worth it.  My internal wiring will come from Reality Cables.</p>\n<p>All of the internal components will be cryo-treated and demagnetized. I was “ordered” to purchase a specific Sn/Cu solder as it sounds the best. Yes solder! As of writing this, I have not found the right binding posts for the speakers.   I am also working on selecting the outriggers for the speakers.</p>\n<p>Construction will not start for a while due to work and family projects.</p>\n",

        "content_html": "<p>Over the last several years, I have been using stand-mounted speakers in my living room system. I have been frustrated by the stands and all the little goodies between the speaker and the floor. While thrilled with the sound, I have been noodling over changing to a floor-standing speaker if there were only something out there I liked. I was not looking, just a tickle in the back of my brain, until Axpona 2025.</p>\n<p>While working at the AXPONA 2025 tradeshow, I took some time to look around, and a little birdie told me to visit this one room with Geshelli Labs electronics and Neil Blanchard Designs speakers.</p>\n<p>The Neil Blanchard Designs 4t4 debuted at Axpona 2025, triggered me, shot me out of a cannon, and more.</p>\n<p>[<a href=\"https://www.nbdesigns.work/shop/p/tower-4t4-mass-loaded-transmission-line-speaker-build-manual\">www.nbdesigns.work/shop/p/to&hellip;</a>\n](4t4 Speaker)</p>\n<p>These little one-meter-tall floor-standing speakers exist in a realm I know little about: DIY speakers.</p>\n<p>What in the world is a DIY speaker? I am traveling down one lightly traveled path with few road signs.  With some help from several friends, I am building speakers.</p>\n<img src=\"https://cdn.uploads.micro.blog/10532/2025/954ef5221e.jpg\" alt=\"Neil Blanchard Desings 4t4 speaker\">\n",
