    Default The inductor upgrade thread - sourcing and part numbers

    So I know there's a bunch of threads related to upgrading inductors, but I also seem to recall them tending to be sub-threads within other, more general, upgrade threads. After spending the last couple hours digging through the results of a couple of searches, I decided to revert to my default lazy bastich self and just ask; what is the consensus on sourcing replacement/upgraded inductors for various Polks? In my case, I'm interested in inductors for my 2.3 TLs, but it might also be nice to collect this information into a single thread, since it does seem to be so spread out over the forum.

    It's a good idea. In our case Polk has lost the data on dcr values of the inductors on the Xovers of the 2.3TL's (I called them). The schematics list the AWG and mH but not the dcr.

    The inductors would have to be removed and measured with the appropriate equipment. I can't remember what that is, but it's not something I own, and it's expensive. Taking the inductor to an electronics shop and having them do it is an option.

    It's something I've thought about, but I don't know of any shops close by that would do this. I wouldn't want to send them off and have them get lost

    What does the inductor do. Do they go bad? Will a different size improve performance?

    Nevermind, I just looked it up on wiki and it's way over my head...but I have seen modified crossovers which included new inductory, maybe Vr3 and Darknight so those guys are way up the food chain in electrocutions of speakers and stuff. My hat is off to those who actually modify these wonderful speakers, and I know there are lots more of you guys doing it.

    Yeah, I've already done nearly the full treatment on my 2.3s. All that's left is inductors, and maybe replacing the high frequency caps with Claritycap MR series instead of the ESAs I have in there now.

    In my case, SDA-2As, I left the Hi-Pass, and Low-Pass inductors as-is. I was interested in the "Full Complement Sub-Bass Drive" inductor, or simply put, the inductor that goes between SDA driver's negative terminal and the amps negative terminal on that side. I couldn't afford a 14 gauge air core, so I opted for an Erse Laminated Steel Inductor. The difference was dramatic to say the least. I doubt the Erse would be applicable to the larger SDAs though, since it's rated for 600 watts before saturation.

    This applies to the SDA-2As, and CRS blade/blade, 3rd generation

    I don't have any Stock crossover parts left in my 1.2tl's or CRS+'s as a matter of fact the only stock parts left on the speakers are the cabinets, drivers, and passives. LOL!!!

    I highly recommend doing the inductors if you can do it.

    You have the specs for 2.3 TLs by chance? I don't.

    Rob, why not just sit back and enjoy the music again before you go stir crazy on those 2.3's again. Also, I'd recommend you start looking seriously at some room treatments before you do any more mods to those pups. I think you'll gain more out of those having seen your room than you would by doing further mods at this point.
