Magnepan 1.7 crossover capacitor improvement?

By the way Stickman451 I took my 1.7's over to my buddies home who owns 3.7's and we did a side by side and he said my 1.7's blew his 3.7's away in every category. We are now in the process of ordering up everything to do his 3.7's crossovers.

Jordi, I am very much interested in making improvements to my 1.7's and was hoping you share your experience / details / schematics of how you went about making those improvements. What type / make capacitors & inductors did you use in your crossover mod?

Thank you very much in advance for your help. Looking forward to hearing from you soon

Thanks,
Shahir

Shahir---Danny Richie at GR Research is well known and respected for his cross-over work (including measuring speakers), and may be able to build you one for the 1.7.

Listen to Jordi, he's exactly right. Do it just like he says. I've upgraded the XO's in my MG12's and it TRANSFORMED THEM. They're much , much more of a serious sounding speaker and I mean in Hi-end aspects not Mid-fi ones. Songs that seemed like filler material now have meaning and purpose, The back and side walls sound like they have been relocated way farther back, it images better, just to mention a few ways it improves them. When I first read Jordi's blog elsewhere I thought he was exaggerating grossly when he said his upgraded 1.7 was better than his friends 3.7, but after I did my upgrade (OMG!) I now believe him completely and I just bought me a pair of 1.7's to do the same with. Do just like he says, leave the stock parts in the speaker and create an external box for the new XO. Also, I found that if you replace the 16 ga. iron core factory inductor with a 12 ga. air core, the resistive value will be very, very close to the factory one which is nice, AND the 12 ga, air core will give the mag's better bass authority than a 16 ga. will. My MG12's had 16 ga. and I think the 1.7 does too. I will verify that when I get mine. All I know is going from the iron cores that are stock you want to go with a larger gauge air core inductor to keep a similar ohm value and get more bass authority. I didn't do that with my MG12's and it didn't cause any noticeable problems (its been over a year of heavy usage) I just missed out more articulate bass. Go with what Jordi says on part brands, don't skimp there. I'm think I'm going to go even more exotic than what he did. I'm having fantastic results with Clarity Cap MR 400v caps in my MG12's. I might go all out and put a Mundorf S/G/O on the super tweeter, but at least a Clarity MR 630v. BTW, I kind of like the way Magnepan keeps the stock XO parts cheap. It gives us guys the chance to customize the way we want the level of sound from our panels. I want them putting the value into the panels and XO design, not the XO parts. I can replace a $10 cap with a $100 one easily, but trying to improve the panel drivers?, I have no idea how I would go about that. Upgrading your XO parts is the only way I know to hear what your Magnepans are actually capable of sounding like.

David, I checked out you system...the cables and Prima Luna have some tendency toward glare in some circumstances.  I Demi's a Prima Luna once and sent it packing for glare issues.  You may find yourself chasing your tail by not seeing the forest for the trees!
