The angled surfaces of the splitter deflect the panel's rearward sound out the open sides of the speaker rather than bouncing it back to the panel. This configuration is more compact and slimmer with a minimal footprint. Woodwork: Red oak front frames / MDF woofer box sheathed in 5mm red oak plywood with oak edging.

wolster Posted August 31, 2013 Posted August 31, 2013 Excellent work, jazzman. Some lovely gear there. Thanks for sharing your system and excellent handiwork.
Steam Posted August 31, 2013 Posted August 31, 2013 Wow! Im impressed. I hope they sound as good as they look. Whats your next project?
jazzman53 Posted August 31, 2013 Author Posted August 31, 2013 (edited) Wow! Im impressed. I hope they sound as good as they look. Whats your next project? Thanks, Dr Nick, I don't have any plans to build anything at least until the hot weather lets up, and I have a bum shoulder that renders my right arm all but useless (surgery scheduled for Friday the 13th). At the moment I have a big pile of nice wood and no ambition. However, I am considering building a removable acoustic lens for my electrostats, for those occasions when I have visitors. Flat panel electrostats have slam and imaging that's superior to curved panels --- in their smaller sweet spot, that is (flat panel stats are so directional, anything said about them should include the caveat "in the sweet spot"). My panels' sweet spot is only about a foot wide and the sound changes dramatically as you move out of the focal sweet spot. As much as I love and prefer their superior sound, whenever company comes over I find myself wishing for a wider sweet spot so that everyone in the room could hear some of the magic. To that end, I'm thinking about a removable acoustic lens that could be added to widen the sweet spot when company comes over, and removed for solo listening. The lens could be very effective but hard to build like the parabolic lens Harold Beverige used in his infamous speakers back in the day, or it could be something simple, like an array of vertical slats (picture vertical Venetian blinds) that could be adjusted to direct the sound. I've done some experiments which confirmed the Venetian blind concept works--- and it might even be possible to hide the slats inside the grill cover. (I have magnetically attached speaker grills but they aren't shown in the photos) Also, one of my hi-fi buddies wants me to help build him a 5.1 setup with DIY ESL's, when the weather cools off and I get my shoulder problem fixed. So perhaps I will be building something before too long. BTW, I just posted my DIY speaker project with lots of photos in the DIY section of the forum. Edited August 31, 2013 by jazzman53

Juicester Posted October 8, 2013 Posted October 8, 2013 geez the poor little thing is mashed in there!
Guest audiophile.1963 Posted November 10, 2013 Posted November 10, 2013 Hi jazzman53, can you kindly give a little aid? I have seen a Behringer DEQ-2496 in your system... I'm thinking to introduce a Behringer DEQ-2496 or a DBX DriveRack PX in my system, is It a good for you? My hifi: ML 331, 380s, 360s, 37, turntable Oracle Delphi V and phono Manley Steelhead 2: I use Klipsch La Scala or a JBL L250 clone (I change every time) in an ambient 4x5x3 m with a lot of mobiles. I prefer the DBX, what do you think about? Ciao e grazie

I prefer the DBX, what do you think about? Ciao e grazie I searched online and scanned thru the DBX owners manual this morning, but I've never used the Drive Rack so I can't make a proper comparison to the Beghriger. I see that the Drive Rack has a sub-out/ crossover, which the DEQ doesn't have, and it's auto-EQ function looks to be easier to use than the Behringer. I once owned a DBX 224 Type II tape noise reduction unit back in the day, which was fantastic, and DBX equipment has a fine reputation, so I'm sure it would be a good choice. I can tell you that the DEQ is dead-quiet and supremely versatile with all kinds of bells and whistles, although it's complex and the learning curve is pretty steep. And the user's manual could be better. The DEQ is a digital unit with AD/DA converters and XLR inputs & outputs, so you would need RCA/XLR adapters it your preamp or receiver doesn't have XLR outs. I'm using the digital in and digital out exclusively; bypassing the AD/DA converters. My signal path is all digital with a single D/A conversion coming out of the crossover, as follows: Logitech Transporter > Toslink cable > DEQ2496 > AES digital XLR > DCX2496 crossover / XLR-RCA analog out > Carver Power Amps > speakers ESL speakers are most revealing and I would describe the sound as dynamic, ultra-quiet and ultra-clean; although a bit "sterile" in comparison to my old analog setup. I like it, though. Charlie Edited November 10, 2013 by jazzman53

Guest audiophile.1963 Posted November 11, 2013 Posted November 11, 2013 Thanks for your reply Charlie, my idea is to use the Behringer DEQ-2496 or the DBX DriveRack PX (http://www.dbxpro.com/en-US/products/driverack-px, here there is the manual) between the pre Mark Levinson N°380s and the power amp Mark Levinson N°331, I have digital and analogic sources, what do you think about?

Max054 Posted November 14, 2013 Posted November 14, 2013 awesome looking system and sweet sounding also I am sure. Congrats loved the Vimeo clip also.
