Pete B Posted June 24, 2010 Report Share Posted June 24, 2010 I have finally completed restoring the Large Advent Collection including the following models listed below, and pictured here:http://baselaudiolab.com/LA_ADVENT1s.jpgAnd here for the 5012/O:http://baselaudiolab.com/JLA_5012_2s.jpgAll speakers were restored with 1% polypropylene caps with resistors addedto approximate the original ESR. Re-foamed with the correct foam. T&S parameters tested both in free air and in system. All XO components tested for value and DC resistance. Tweeters T&S parameters tested. All non gas tight connections tested for DC resistance (<.005R) and treated with DeOxit.Please note that I have used 1% caps because the original caps often measured better than 5% and I did not want to use inferior value caps,and also did not want to have to hand select each one. All old componentsthat were reused were tested for value. New components were also testedas a QC check simply to verify the correct value. All of these speakers areotherwise completely stock with original fiberglass stuffing in the OLA and 5012/O, and foam stuffing in the NLA. 1. Original Large Advents (OLA) from 1972 owned by my family since new. One woofer replaced.2. New Large Advents restored as above. Tweeters replaced due to what was believed to be ferro-fluid issues. New linen grille cloth.3. Jensen 5012/O the /O indicates real oak veneer cabinets. All original drivers.I've given all of these speakers a listening check and they are free of anystrange noises or distortions, and are well balanced side to side.I continue to be highly impressed by the OLA (with 4dB of BSC) where theycompete and in fact beat many modern designs. They are set up in mylistening room in case anyone from Stereophile or Affordable Audio would like to hear them and perhaps review any of them. Might make an interesting article on how to build a budget system with main speakers costing less than $100. These would work well for HT without a sub, and even better with a pair of budget subs such as the HSUs. Link to comment Share on other sites More sharing options...

My first "brand new" purchase of now "classic" NE speakers were OLA's, way back when. I would love to hear your BSC application sometime.We are not that far from each other. A road trip is not out of the question. Roy Link to comment Share on other sites More sharing options...

RoyYou're welcome to visit anytime Roy, I've always enjoyed our discussions.I have an A/B switch with line level volume matching in case you or anyone is interested in comparisons.

ironlake Posted February 6, 2012 Report Share Posted February 6, 2012 I do not see a photo of the original hardwood advent, the one with the moulded wood frame. Link to comment Share on other sites More sharing options...
Pete B Posted January 24, 2016 Author Report Share Posted January 24, 2016 It is not a complete collection, just what I stumbled across in my search to cover the design of most of the Large Advents.I should probably add the Anniversary Edition also for kicks.
