  1. Yes, the Driverack has a control module that enhances bass response. I use in on older recordings that were not recorded with punchy/deep bass. Here's an excerpt from the user manual: DriveRack PA+ Section 5 ® Detailed Parameters Number Fixed - 0-12 This will range from values 0-12. The total number of filters will stay at 12, and the number of live filters will be = Total Num Filters – Num Fixed. If this is changed before the filters are reset, then the filters will be reset one by one as the number changes. For example, if the number of Fixe
  2. I'm using the Behringer mic because I already had it when I purchased the DBX. BTW; the DBX setup wizard has a prompt to select either the DBX mic or non-DBX mic.
  3. HI Grant, Two friends who I built ESLs for are using the Driverack PA2. I'm still learning all the features but I'm pretty sure that everything you would use in a home stereo application (crossovers, EQ's, limiters, time-delays, etc.. ) are identical in the PA2 and Venu 360. Both have six output channels. And aside from the extra/digital inputs on the Venu 360, the other differences apply to PA applications where you might need to daisy chain components. For example; the Venu has three separate input processing chains (versus one in the PA2), as well as capability t
  4. I'm not yet sure if the DBX can do that, but it does have dynamic limiters.
  5. I don't know whether the DBX would have a shutdown thump because I always shut the amps off first. And at startup; I always turn on the Logitech streamer and Venu 360 first.
  6. 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 less expensive PA2, only because I needed the Venu's digital inputs to accept the digital out from my Logitech Transporter. This will not be an in-depth, dispassionate, or measurement based review. I still have a lot to learn about the Venu 360, and the Behringers are all I know to compare it to. Below are my initial impressions: Behringers have a less than stellar rep among aud
  7. Hi all, I decided to build hard-case transport boxes to protect my new Jazzman Mk III ESL speakers during the annual trek to Carverfest. The hard cases can be carried in the back of my truck, even if it's raining. The cases are two-piece interlocking clamshells made from light weight 3/16 plywood painted with truck liner coating. The clamshells snap together with (6) draw latches, and a foam rubber gasket between them seals out the rain. The lower clamshells have carrying handles on each end, for two person carry. Interior surfaces which contact the speakers are S
  8. Thank you! Yes, I did build the rack as well. The [class G] Carver amps run surprisingly cool-- I have some spacer blocks between them, and the shelf above is slatted for air flow. The two Behringer signal processors generate a fair amount of heat (they get hotter than the amps)… so I may need to do something about that.

  10. 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 great. I finally now have my dream speakers for life, and I'm sure the recipients of the other three pairs will feel the same way. I'll just leave you with a last VIDEO showing the speakers playing. Enjoy! Charlie
  11. 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 poplar bowed a bit less. So I'm cutting the stiffeners off and bonding new stiffeners on with the frames purposely bowed in the opposite direction, hoping they will bow back to near straight condition. I may end up giving them a week or so to stabilize, then cross cutting slots in the vertical stiffe
  12. 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 the Peerless SLS-- I was concerned it wouldn't be up to the task so I only ordered one pair initially. I should point out that so far I've only sound tested them chopped off at 60Hz and crossing into a pair of Ripol subs with a 24db filter slope. Thus unloaded on the bottom end; the Peerless woofer
  13. I've been building ESLs since 2008, starting with perf-metal stators, then segmented welding rod stators, and a few years ago I started building electrically segmented wire stators. I didn't invent wire stator ESLs or electrical segmentation-- I only applied those principles to my designs, which include this speaker. I think the most innovative part of it was the wire stretching jig; as I've never seen one like mine. To the best of my knowledge Accoustat built the first commercial wire-stator ESLs and I'm not sure who first introduced electrical segmentation --- that might hav
  14. Update Saturday March 14, 2020: The panels and segmentation resistor networks are installed in all eight speakers. Today I installed Peerless SLS 12 woofers in one pair and they're playing tonight. I delayed ordering woofers for the remaining speakers until I've had a chance to audition these. My first impression is the SLS 12's will be fine. I still have to build the grills but it feels good to be wrapping this project up after 5 months of toil. The photo and video below were made today.. enjoy!
  15. You’re heart’s in the right place but that one looks like a boat anchor to me.
  16. Update Tuesday March 3: All ( ESL panels, power supplies & speaker frames are completed. Now assembling the (16) segmentation resistor networks. Still have to buy woofers and make the grills. Here's another video; showing the diaphragms being installed and the panels assembled:
  17. Amplifier/ESL interface (high voltage bias supply and step-up transformers), located on the lower rear shelf of the speaker:
  18. 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 been twisting my arm for years to build some speakers for them, but until now I've declined because my designs are exceedingly tedious and exhausting builds, especially for an old guy (66) like me. I must have bumped my head somewhere because I finally agreed to do it. I'm about 85% through building four (4) pairs of an OB hybrid design that uses a 12
