HQD Posted April 15, 2019 Share Posted April 15, 2019 Item: Bohlender Graebener RD75 ribbon speaker driver pair Location: Templestowe 3106 Price: $1620 Item Condition: Good working order, fully tested Reason for selling: Estate sale Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: May be used full range from 200Hz to 20KHz with just a simple sub to fill in the bass. These are the ultimate speaker for detail and directionality. These normally bring A$3,000+ on the international market but I need to keep this fast and simple for the family of my deceased audiophile friend. Price $1620 is not negotiable - if you don't think they are an incredible bargain at this price then you don't really want them! I am not taking a commission on this ($1,600 is for the family and $20 is for Austereonet) so you need to keep this easy for me also - buyer to collect or arrange their own collection and wrapping. (I can drop to the nearest pack and send store in Blackburn though if that helps.) I did a full test last night using a borrowed Audiomatica CLIO system and can confirm both are working perfectly and are a good matched pair. (NB Pic is from the web but identical to the pair I am offering) Some info, including specs, here: https://www.diyaudio.com/forums/swap-meet/306011-sale-pair-nos-bohlender-graebener-ribbon-transducers-rd-50-rd-75-a.html Pictures: Link to comment Share on other sites More sharing options...
Guest Posted April 16, 2019 Share Posted April 16, 2019 One of the best if not the best tweeter arrays out there.Similar sound to Genesis,Infinity,Magnaplanar but more forgiving.I was lucky enough to have heard these with the commercially made setup from the USA which the speakers were selling for around US$10000.

Lansche plasma guy Posted April 17, 2019 Share Posted April 17, 2019 Excellent Ribbons. 20 years ago or a little longer. The smaller 60 inch ribbon was used in the Genesis of the time. Due to the cavity resonance and the dispersion and driver characteristics they were used with the circular genesis ribbon tweeters but i found mine had really nice top end used without tweeters. Had them crossed over at 150-200hz to 10 x 12 inch Tonegen woofers (5 per side). Was equalised with a Clearview active crossover to supposedly go down to 16 hz. The housing for the RD75 was a very simple two pieces of wood (ash) screwed into the sides and a base plate. Sounded fantastic. Excellent Ribbon good luck with the sale.

HQD Posted October 27, 2019 Author Share Posted October 27, 2019 These are available for sale again as the original buyer never collected them. Great speaker components, very hard to find locally. Please be serious if you say you want them. Link to comment Share on other sites More sharing options...
