Modifying Crossovers


I just read a post about changing resistors and caps in the new Borresen X3 speakers. I am curious why there is interest in changing the components in a brand new speaker. I also am curious if it would make them better than why didn’t the designers put a better component in the first place. Just a thought and scratching my head. Have a great day.

Yep. My lowly B&W 802 series 3 were probably built in 97' when I discovered Troels Gravenson speaker building designs,I was stoked when he does a crossover upgrade for these speakers. I couldn't buy the kit fast enough, talk about a fun project. Most rewarding project I've ever done. I'm gonna tear into them again one day and replace these parts with even better Jantzen parts and silver wire. I could've easily asked Jantzen for his better products and wish I would've.

A diy speaker project is in the works also. 

@carlsbad2, with regard to the Duelund bypass caps, I'm curious to know if you listened to your system before installing the bypass and what change you heard after, also which ones did you chose?

@jaytor, very nice set up you have there and I notice in the photo you provided of your XO that you too appear to use Duelund bypass caps. As there are a variety of Duelunds caps I'm asking because I wish to buy once and cry once 🙂

I'm using the Dueland 0.01uF JDM Tinned Copper Foil Bypass caps on both the tweeter series cap and the midrange shunt caps, I didn't really notice much if any difference on the midrange caps, but they added a touch of sparkle and airiness in the tweeter circuit. 

I added these before the crossover caps were burned in though, so I'm not sure if they would have had the same affect after burn-in. But I'm really happy with the way my speakers are sounding now so don't want to make any changes. 

@jaytor your values may be too small.  Try 0.1uF.  I use Ayudin True Coppers.  Sorry for the spelling.

I don't think the issue here is the brand, but a lot cheaper than the Duelunds.

 I had an old pair of JBL 212's with the sub given to me. I changed the capacitors to new Sonus (I think they were called) capacitors. They really sounded great - big difference, so much so that I regretted selling them. 

 Capacitors don't wear out but the newer caps are much improved. Swapping out the older for newer caps is not a difficult job, just remember to label the speaker polarity.
