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.
@vair68robert The before crossovers are still installed. I pulled them out enough to sketch a wiring diagram and reverse engineer them. Here are a couple of photos (i use google photos, would appreciate any advice on how to get a preview to show). Upper and midrange crossover: https://photos.app.goo.gl/Fh2wFvdbFAcm8AqU6 Bass crossover https://photos.app.goo.gl/7oJtoz7v72gsC3s47 I'm obviously combining them onto one board. Jerry |
Many times crossover parts and values are selected to get the sound the designers wanted. Just putting in costly parts in many cases will make the speaker sound worse. Different parts have different insertion values you may end up altering the output of one driver over the other or cause the amp to see different OHM loads or have phase issues toss in the fact that most don't even know how to solder properly and it's an overall dumb idea to do. But the audiophile will why I don't consider myself an audiophile I have grown out of it. |
@johnk I respectfully disagree with you. I'll fight to the death for your right to your opinion. Do you have an example of someone you personally know, even better yet, that you heard before and after, of that sounded worse. I have a friend with a similar speaker to mine. Mine sounded better before the upgrade, now his sounds much better. Every manufacturer is different, but IMO even high end manufacturers tend to cut corners on the (invisible) crossovers. Jerry |
Thanks , I can see why you are moving the crossovers out of the cabinet . This is something I have thought about and something highly recommended by Tom Thiel , but making the external cabinet is not part of my skill set . I have pictures posted on the virtual systems of my before and almost complete after crossovers , I just installed the newest Clarity capacitor on the tweeter board and am waiting for Clarity to release the full range of caps to finish with the 1uf for the mid range . My work doesn't look near as refined as yours . Rob |
@vair68robert I toyed with the idea of having my crossover box made by a friend that does woodwork. Since there are no external controls it isn't hard to make. Seems making boxes and selling them is a nitch that someone should fill. I don't enjoy woodwork enough and don't need a new business but it would not be hard to mass produce them. Maybe I'll find a young guy and back him financially. My plan was to replace components on the boards and leave them internal. I was going to have to add a 3rd board for the large inductor. In fact I made one of them but it was going to be real tight. Here is one of the boards (since disassembled): https://photos.app.goo.gl/stNMSckHnLVPngVdA :
