twinsig Posted September 13, 2021 Report Share Posted September 13, 2021 Just scored what appear to be The Advent Loudspeaker (according to the label on the Xo plate). Is there a nice XO MOD for these? I tried to access the "baselaudio_la_xo" link with no success. These have the masonite woofer (need surrounds) & screen covered tweeter. AND the squared-off front bezels, not the rounded bezel. Please, for the sake of sanity and my vision, could someone provide input or links to any XO improvement mods?

RTally Posted September 14, 2021 Report Share Posted September 14, 2021 No mods needed. Unless you want to add Baffle Step Correction (BSC), but that is an advanced mod. All you need to do is recap the crossover. I recapped all of my Advents with the same value capacitors as is already installed. I use Dayton poly film. Use the same cap value. Wire caps in parallel (values add when in parallel) if you cannot find the same value as the original. The voltage rating can be higher than original. I generally re-use the original inductors and resistors unless there are signs of damage. Quote Link to comment Share on other sites More sharing options...
lARrybody Posted September 14, 2021 Report Share Posted September 14, 2021 What you have is what we call OLA (Original Large Advent) though Advent never used this name. For a more detailed discussion about your crossover look at this thread. RTally is right about no mods are really needed. Identify which revision your crossover is and go from there.

Doug G. Posted September 17, 2021 Report Share Posted September 17, 2021 Yes, no modification necessary. The crossover, as is, does just what it needs to for those drivers. Quote Link to comment Share on other sites More sharing options...
twinsig Posted October 3, 2021 Author Report Share Posted October 3, 2021 Thanks y'al.. finally opened em up and found 16uf/8uf/3ohm-10w resistor. PE doesn't list a 16uf but do offer 15 or 17. Would either of those make a difference? One of the oems measures 19, the other is way off. I'm only using MM to test though. Quote Link to comment Share on other sites More sharing options...
Doug G. Posted October 4, 2021 Report Share Posted October 4, 2021 A revision 2 crossover as on Pete's site. You can use two 8uF capacitors in parallel for the 16 if you can't find a 16uF anyplace. Doug Quote Link to comment Share on other sites More sharing options...
lARrybody Posted October 10, 2021 Report Share Posted October 10, 2021 PE has your cap. https://www.parts-express.com/speaker-components/crossover-components/crossover-capacitors/metalized-polypropylene-crossover-capacitors/capacitance/16-uF The matching 8uf cap can be found at Madisound.

twinsig Posted October 11, 2021 Author Report Share Posted October 11, 2021 Submitted my PE order today for Jantzen caps for the Olas & some ARs.. first ever woofer refoam seemed really simple. We'll see soon enough. Or hear actually. Quote Link to comment Share on other sites More sharing options...
