owlsplace Posted November 12, 2016 Report Share Posted November 12, 2016 Measure the cabinet size -- it looks like a one-off Elwyn model. Chances are removing that back panel will reveal the original cabinet. Roger Link to comment Share on other sites More sharing options...
Gianfilippo Posted November 12, 2016 Author Report Share Posted November 12, 2016 Thanks Roger. I've just bought on eBay. When the shipment arrives I measure it. I do not know Elwin model. Link to comment Share on other sites More sharing options...
Gianfilippo Posted November 24, 2016 Author Report Share Posted November 24, 2016 Hi Rogers the cabinet size is 10 x 19,7 x 9 ( L x H x P) a bit higher of my 4xa. What do you think about it ? Tks Link to comment Share on other sites More sharing options...
Gianfilippo Posted November 24, 2016 Author Report Share Posted November 24, 2016 The grilles has a black stripe at the top (probably a later addition) Link to comment Share on other sites More sharing options...
ra.ra Posted November 24, 2016 Report Share Posted November 24, 2016 Those cabinets are indeed something of a mystery. With the exception of the height, your measured cabinet dimensions are consistent with original published dimensions, and the added dimension of the black stripe on the grille seems to be consistent with the discrepancy in height (0.7 inch, I presume) that you have already confirmed. Your grille frames are not original, and they appear to be no more than 1/4" thick (6.5 mm), but the recess of the front baffle does not seem sufficiently deep to accommodate them, particularly with the addition of velcro tabs. But the real curiosity is the backside, with what appears to be an additional screwed-on rear panel, a finished edge on all of the cabinet side panels, partially relocated paper labels running 90° to the normal orientation, and the black collar around the opening at the controls and terminals. I suspect this mystery will not be solved unless some minor disassembly is explored, but meanwhile, can you confirm if that finish is real wood veneer or a simulated "faux" finish like adhesive vinyl?

Gianfilippo Posted November 24, 2016 Author Report Share Posted November 24, 2016 Yes the only discrepancy is 0,7 inch in height. I think that the black stripe on grilles is a later addition to cover moisture problems. I have to send to repair both of the speakers and I ask to do interior photos.The rear opening will be useful for the repair. The finish is real wood veneer. On the front there is no trace of white glue, only black tar. The front edge in wood has a small chiseling as a small step, from the photo is not perceptibile.

What do you think about it ? Tks Gianfilippo, Best guess is that the original speakers were water damaged -- repairs to the boxes were made and new veneer applied. The black section of the grill cloth was to make up for the extra material needed for the longer box. I bet they sound fine. Roger Link to comment Share on other sites More sharing options...
Gianfilippo Posted November 25, 2016 Author Report Share Posted November 25, 2016 But is not easy to saw an AR cabinet .. Ok Roger so you say a e repair with subsequent intervention with veneer applied .. but how do you explain discrepancy 0,7 inch in height .. the front edge in wood with a small chiseling .. the black collar .. the front baffle not seem sufficiently deep to accommodate grilles ..Maybe the cabintes have been built entirely from new? But it si possible that they did it with all this care to details? Link to comment Share on other sites More sharing options...

Gianfilippo Posted November 25, 2016 Author Report Share Posted November 25, 2016 WoW beautiful. Ok it remains to see what's inside the AR4X modified. I hope do not find a chaos .. the sound is detuned, muffled and both of ceramic control pots not working. I have to figure out it makes sense to repair them. Thanks for all .. I will post pictures of inside. Regards Link to comment Share on other sites More sharing options...
Gianfilippo Posted December 15, 2016 Author Report Share Posted December 15, 2016 I'm sorry .. I had asked to the technician some pictures of inside the cabinet, but he sent me only those of repair. However he believes that the cabinet have been built entirely from new. The capacitors of crossover had already been replaced from prevoius owner. Looking at the photo do you know to recognize them? Are these capacitors valid products? Link to comment Share on other sites More sharing options...
owlsplace Posted December 15, 2016 Report Share Posted December 15, 2016 Most would probably use a film cap these days rather than the electrolytic cap shown but it should work fine. Here is a common schematic for the 4x: There were quite a few different factory variations of this model with different woofers, crossovers and alternate tweeter phasing. I may try Dave's mod at some point which is detailed in this thread: Roger Link to comment Share on other sites More sharing options...
