These custom open bewilder speakers were outlined by John Kreskovsky of MusicandDesign.com, and worked by me quite a long while back, with heaps of exhortation and direction from John. All drivers, the hybrid, and the included bass amp all work fine, and cosmetically these look great (no scratches or scratches on the cupboards, the drivers all look and perform like new). The drivers are the Seas Excel T25CF-002 Millenium tweeter, double Scan-Speak 18W/8545 midranges in a D’Apollito setup, and Peerless XLS 830500 12″ woofers in a U-outline bureau. The back terminating tweeter is a Vifa D27TG-45-06. The hybrid between the mids and tweeters is detached, constructed utilizing Sonicaps, Solens, and custom Cello polypropylene capacitors and air center curls. The tops were chosen and coordinated to inside 1% for channel to channel equalization. An electronic hybrid/EQ (included) separates the mid/tweeter drivers from the woofer, and gives the required dipole leveling to this setup. John K. has charitably given me various overhauls to the hybrids (both latent and electronic) since they were first manufactured, all of which have been fused here.
The cupboards are worked with baltic birch employ overlaid to MDF utilizing the strategies recommended by George Short of North Creek Music Systems. The base is veneered in cherry, and the mid-tweeter boards are veneered with 10,000 foot maple, wenge trim, and strong cherry around the border. Grilles for both the mid/tweeter boards and for the woofers are incorporated, in addition to there are little round barbecues over the back tweeter.
This speaker configuration is an immediate contender to the Siegfried Linkwitz Orion speakers, yet for me, the key contrasts were: a) this outline utilizes just 2 stereo amps (one of which is incorporated with these speakers) versus the 6 or 8 amps required for the Orions, and b) the Orions put handfuls more ICs in the sign way, which was not appealing to me as I lean toward a more straightforward sign way.
Hybrid/EQ: My setup is completely adjusted (XLR associations), so the hybrid I fabricated is additionally completely adjusted, which means four of everything (rearranged and non-reversed for both left and right). The hybrid/EQ sheets are constructed utilizing Roederstein Resista resistors, and MIT PPFXS polypropylene film and thwart tops in the mid and high pass segments. There are separate controllers for every channel that utilization MUR860 ultrafast TO-220 diodes, Panasonic 105 degree tops, and heatsinked LT1033 and LT1086 controllers.
Woofer speaker: I incorporated the hybrid with an expansive case alongside a 125watt/channel Class D Audio SDS-252 stereo enhancer for the woofers – high effectiveness, and it likewise runs completely adjusted. The amp additionally incorporates a delicate begin circuit, subsequent to the amp incorporates bigger than stock force supply tops for better bass control. This hybrid/EQ/intensifier incorporates a 12volt remote trigger to turn it on remotely. I utilized a re-purposed Audio Research faceplate for an extremely proficient look. That amp/hybrid combo implies that you just need a solitary stereo amp for these bi-amped speakers.
John at Music and Design has subsequent to advanced this configuration to utilize the MiniDSP computerized hybrid, and John has demonstrated he’s work with the purchaser to make that move for this set if craved. John likewise demonstrated potential purchasers were welcome to get in touch with him with any inquiries concerning the speakers.
Measurements are as per the following:
Speakers: 53″ tall, 13″ wide, 24″ profound
Hybrid/EQ/bass amp: 5-7/8 tall, 19″ wide, 19″ profound (with handles)
This deal incorporates the left and right speakers, the completely adjusted electronic hybrid with the 125 watt for each channel bass amp. Schematics for both the dynamic and aloof hybrids will likewise be incorporated.
Note that these are for neighborhood pickup in Stamford, CT.
