Guest wbz Posted January 9, 2007 Report Share Posted January 9, 2007 Now that I have been edumacated :-) that the New Large Advents have completely, alright radically, different crossovers I'm wondering if anyone has ever replaced a New Large Advent crossover components to make it like the original Large Advent crossovers? This has been touched in in some threads but I thought it needed it's own thread. Link to comment Share on other sites More sharing options...
Guest sbalfour Posted February 11, 2007 Report Share Posted February 11, 2007 This belongs in the mod'ers and tweakers forum if you want to gointo detail or design one. If what you ask is literally what youwant, you can take an original Advent Large and replace the tweeterwith a new style ferro-fluid one :-| The masonite framed woofers are sonically to the New Advent stamped metal frame ones. So you get aNew style system with an old-style crossover. Alternatively, you can occasionally buy used Advent Large crossovers on Ebay and substitutethem into a New Advent box. What you propose isn't what you want to do, however, because thecrossovers are an integral part of the system design: they're highlydependent on the exact driver parameters, box volume, stuffing, andother characteristics of the system. You can't swap the crossoverfrom one system with that from another. In particular, the New ferro-fluid tweeter has resonance at 1900hz vs 670hz for the original tweeter - it needs a much higher rolloff than the old one, and thatimplies a completely different high pass filter and crossover.I think the above won't answer your real concern - what is it, inacoustic terms, that you are trying to change or "fix" in the NewAdvent?

Guest wbz Posted February 11, 2007 Report Share Posted February 11, 2007 Actually, that is exactly what I was looking for. I didn't realize the low end of the newer tweeter was so high. thanx Link to comment Share on other sites More sharing options...
