Van_Isle Posted January 9, 2009 Report Share Posted January 9, 2009 Does anyone have schematics or otherwise any info on the crossovers for Advent/1's? Perhaps I missed it, but I'm not seeing that info in the library or otherwise through searches of the forum.Thanks Link to comment Share on other sites More sharing options...

Perhaps I missed it, but I'm not seeing that info in the library or otherwise through searches of the forum.ThanksIt is Figure 4 at this link with the switch removed which keeps the inductor in circuit and leaves 2.5 ohms in series with the tweeter circuit. The 2.5 ohm is a single 10W sandcast resistor:http://baselaudiolabs.googlepages.com/ADVENT_LA_XO.htmlThe Advent/1 is essentially the New Large Advent in a smaller box, with the XO simplifications that I mentioned above. Drivers are the same. I like thedesign. Link to comment Share on other sites More sharing options...

Guest Audiomark Posted January 28, 2009 Report Share Posted January 28, 2009 I'm pleased to say that the crossovers on my /1's are far more neatly built than any of those in the link!The X/O is very simple, just an inductor in series with the woofer, and a 13 uF electrolytic cap and 1 ohm sand cast resistor in series with the tweeter.They now have paralleled poly caps, an Eagle MOX, Michell posts and upgraded wiring, which completely removed some very audible harshness, apparent particularly on brass.Leaving a remarkably good sounding speaker.

AltairHi, Google pages has changed to Google Sites where they now onlyallow sites that use their templates for web pages. My Google pagesdid not conform and so did not port to the new Google sites. I'm currently looking for the best free hosting and am open to suggestionsbased on experience. Should have it back up within a week or so.What is interesting is that the pictures still work, just the html is notallowed.Ah, here it is in the Google cache which should work for a while:http://74.125.93.132/search?q=cache:CeLZz_...VENT_LA_XO.htmlWayback might work also.
