    DBX Drive Rack Venu 360

    I recently replaced the Behringer DEQ2496 EQ & DCX2496 crossover driving my homebuilt hybrid electrostats & Ripole subs, with a DBX Driverack Venu 360 crossover/EQ. I opted for the Venu 360 over the PA2 only for its digital inputs, which allows me to feed in the digital out from my Logitech...

    Carver & DIY ESL two channel system

    Tom, In 2015 (or maybe it was 2016) I brought the big beam-splitter ESL's to Carverfest, which you may have heard. But I believe the speakers I brought to Carverfest two years ago were the ones I built for Martin Fringe, which were the prototypes for the new ones shown above (and below)-- but...

    Carver & DIY ESL two channel system

    Yes, I'm very happy with my new speakers... they are the culmination of 13 years and many iterations of building ESLs. The Ripole subs also use the Peerless SLS 12 woofer. For a cheap woofer, the SLS is quite impressive-- just does everything well. They are advertised as subwoofers (fs 27Hz)...

    Carver & DIY ESL two channel system

    I just built my dream speakers for life and I'm updating my system post to show them: I've sold my old beam-splitter transmission line ESLs and my new system is now fully dipole, with OB mid-bass woofers and Ripol subs. The panels are wide-dispersion, symmetrically segmented wire-stator...

    The big lie - Dispersion Horizontal: 30 Degrees

    I'm wondering if the Essence panel is segmented. If so; it would have significantly wider dispersion than a non-segmented flat panel, or perhaps even 30-degree-arc curved panel. Does anyone know?

    Yet Another Hybrid ESL Project

    Hi all, This project (all four speaker pairs) is finally completed, so this will be my last post on this thread unless it's in response to others. I resolved the issue with the grill covers bowing and they turned out gorgeous. I finally now have my dream speakers for life, and I'm sure...

    Yet Another Hybrid ESL Project

    Update 3/26/20: Having a lot of problems with the grill frames. They looked great the day I built them but they bowed after a couple of days and I'm having to redo them. The first time I used white pine stiffeners on the hardboard frames, the second time I used poplar. Both bowed but the...

    Yet Another Hybrid ESL Project

    Update 3/23/20: All four pairs of speakers are fully completed except for the magnetically attached grills, which I started building today. I spent the weekend sound testing every pair, and they all play to ridiculous volume with no apparent issues. For a $77 woofer; I'm pretty impressed with...

    Yet Another Hybrid ESL Project

    Today I got "first sound". That is; I completed and played one pair of speakers today. I have to order the woofers for the other three pairs. On the pair I finished today I'm using Peerless SLS 12's and my fist impression says these inexpensive woofers are going to work fine. At the moment I...

    Yet Another Hybrid ESL Project

    Update Tuesday evening, March 3: The speaker frames have been completed for weeks. I've just completed assembling all eight ESL panels. I'm about halfway thru assembling the (16) segmentation resistor networks. Still have to buy the woofers and build the magnetically attached grills. I...

    Yet Another Hybrid ESL Project

    Yes, I think I spent more effort designing that stator jig that I did designing the speaker, lol. The project is coming along.. all the panels are built and now soldering up the segmentation networks, and then I will do the grill covers. These will be the prettiest speakers I've ever built...

    Yet Another Hybrid ESL Project

    The Maggies are fine speakers; although they use a different drive principle than electrostats. I have no education beyond high school so; self taught. I've had a lot of help over the years from the online community of ESL builders that post on the DIY Audio Forum, planar section. There's...

    Yet Another Hybrid ESL Project

    Yes! That's a great analogy with the 63. For coating the diaphragm; I use Licron Crystal ESD, which is a spray on product that puts an static dissipative coating on plastics. It dries to about 2 microns thickness with E7-E9 resistance. I've been using it for about 10 years now. It's not...

    Yet Another Hybrid ESL Project

    Hi all, Since October of last year I've been toiling away on my biggest-ever ESL speaker project. And in the coming weeks I will be posting some photos as the project nears completion. Several of my Carver Audio friends have twisted my arm for years to build speakers for them, but until...

    Finally gonna do something about my room...

    Update July 7, 2019: I've just finished the two corner traps shown below, and that completes all the panels I had planned for this project. In total; I've built the three rear wall panels (two with 2" Rockwool 60 and center panel with 4" Rockwool 60), a single pedestal panel with 2" Rockwool...

    Finally gonna do something about my room...

    Update Tuesday July 2: I've completed three wall panels and a pedestal panel, all with 2" thick, 6lb density Rockwool and exposed brown oak frames. One of them is a 56" x 42" panel placed over a window behind the sofa and covered with a Carverfest banner. Tomorrow I will start the...

    Update Saturday June 29: I have the big panel's frame (that will cover the window behind my listening position) and three smaller 24 x 48 wall panel frames essentially completed--- just applied the first coat of satin polyurethane, which will be sanded and final coated later today. The big...

    Cross-connected coaxial speaker cables

    The cables I was using before were also DIY cables, except they used Mogami coax cable with the stranded spiral wound shield conductor; which I believe is the very same cable used in the $600 ESL speaker cables sold by Inner Sound. Those cables sounded just fine, as do my new cross-connected...

    The Eros Clone DIY Electrostatic Speaker

    Hi All, The exquisitely crafted speakers shown below were built by my online collaborator, Mervyn Tims. I have a website (Jazzman's DIY Electrostatic Loudspeaker Page) dedicated to building electrostatic speakers, and I often receive requests for drawings of my (3) ESL designs. Most people...

    My Beveridge Electrostatic Speaker System

    Nice work, Ted I was admiring your room too, especially the wooden structure on the back wall which I'm guessing is some kind of cabinetry? Also, the two items on pedestals behind your mains caught my attention-- are those additional speakers or bass traps? And are you still using those same...

    Finally gonna do something about my room...

    Hi all, I'm inspired to build some DIY acoustic panels for my living/listening room after hearing a really exquisite system setup in a dedicated sound room. I was absolutely floored by the tight, crisp quality of the bass notes. The owner explained that he had spent a lot of time dialing in the...

    RIP Dr. John

    Sad news indeed. I'm fortunate to have seen him play on two occasions in Savannah, and of course; he was fantastic!

    Horn based system from southern coast of Turkey

    I love your system and room Komodo... and you're a very lucky guy to have a wife that shares (or at least accommodates) your passion for audio. I haven't heard anyone comment or mention the ceiling diffuser... did you build that too? And is it made of wood or foam blocks? Nice work!

    DIY ESL's

    Yes; I've built several different types of panels and the welding rod panels were an interesting project. Before I learned about electrical segmentation I had no idea it was possible to widen a flat panel's dispersion and curve its wave front electrically. Generally; unsegmented flat panels...

    DIY ESL's

    Oh geez guys, thanks so much for the compliments on my speakers and website. I seldom build speakers these days (even DIY ones aren't cheap) but I get almost as much satisfaction from my website. I've sent years attempting to make it a one-stop resource to convince other DIY'ers to take the...
