I really enjoy your video! You did the same as I did on my Polk S20 by putting better parts on the crossover and I changed the Polyfill for acoustic foam to better dampened the cabinet. Sounds more controlled and refined now. Thanks !
I'm buying a used SP-C21 tomorrow. I'll be sure to inspect the crossover and try to replace the caps and inductor when I have the time. Thanks for inspiring me man.
Have you done the mods on the SP-FS52 yet ? I just picked up a pair for $120 so I don’t mind spending a few dollars on modification and maybe lining them with some NoRez dampening material Been watching GR Research on crossover network modifications. I think I’m ready to tackle that now
I change the capasitor and resistors of SP FS52 and it sounds great. I was not able to measure the inductor. Remaining parts I changed with audio quality We need 1.8uf,15uf,150uf,1.8ohm 10W,3.9ohm 10w, 2.2ohm 10W. I kept both inductors unchanged. It's sounds great
@@ranjithps3303 they LCR meter so I’ll be able to measure the inductor. But I know when you switch over from an iron core inductor to an air core inductor , The air core and doctors are many times much larger on top of that using thicker gauge wire. And switching over from electrolytic capacitors to poly caps are many times larger and film cabs. Probably when finished it will have to be made on a new board and will not fit back through the speaker whole I’ll probably have to mounted outside on the back.
@@coldfinger459sub0 I didn't replace iron core inductor and the air core inductor,other than that I replaced everything. It is really small gap to put it in. My fs52 is 7 years old and the screws are all rusted,have to replace that. Response is entirely different now, the capasitor was so week that when I pulled it just got ripped out.
Hi - thanks for the video. I just bought this speaker and notice the muddiness of the lower frequencies you mention. Could you share the parts list for the replacement components? Any challenges mounting the air core inductor in place of the iron core inductor? Looks like some zip ties is worked for you. Thanks!
@@audioupgrades7759 Thank you. I ended up replacing the tweeter with a recommended upgrade (Peerless by Tymphany BC25TG15-04) but left the cross over as it was. I applied a little equalization to up the 500 to 4000 Hz amplitude by 2 to 3 dB and now the dialog is more clear to my old ears.
@@dennissmith9664 Dennis Murphy had a simple mod by adding 2R2 and 3.9uF to the tweeter if you want to try that www.diyaudio.com/forums/multi-way/222977-mods-improve-andrew-jones-pioneer-speakers-post6112256.html
@@daijoubu4529 Hi - I was confused by the Dennis Murphy mods for the bookshelf speakers where he recommended not using a resistor on the SP-BS22-LR tweeters, but re-reading the link you provided I realized my mistake. Last night I added the capacitor and it made a huge improvement to the high frequency sounds. I am now running without the equalizer adjustments and a level just +2dB produces much better and easier to hear dialog. Thanks!
Can you link to the parts you used? I bought a used one and its a bit hollow and feels like there are some echos. I have no technical skills or way of knowing what is a good quality piece or if the numbers mh need to be the same or not.
Hey man, how did you know the value of the inductor? Did you take it out and measure or do you have any formula based on those capacitors and resistors?
@@patricksuckoo232 thanks I eventually figured out the 18 awg could handle 300 watts rms. It's there a general rule about how much overhead you would want?
They are called bucking magnets, and they are not necessarily to make safe for use around a CRT. (They don't necessarily provide protection ether.) Some manufactures use them for enhancing the magnetic field or something, to enhance the bass driver. My JBL Studio 590's have them on the bass drivers and I really doubt it's so you can put the speaker next to a CRT.
Super upgrade .. No matter the design if the parts end up cheap in a Chinese factory what's the frigging point! A. Jones should take a good look at how Pioneer cheaps him out! May be that's why he moved on!.
China is not really the problem. If you got money they can give high quality products. The problem is Western or any other countries' brands' obsession with cheap parts.
Cool! I'd like to know if anyone has modified the Micca Mb42's, i brought the regular ones like two years ago, they are decent speakers but they could definetelly use a crossover, the only problem being that Micca won't ship that specific component outside of the US so my only options are: A) buid a crossover on my own ( i am hesitating of this because i have 0 experience doing that) B) look online for some other crossover. I hope that anyone can help me. Great video by the way
The upgraded crossover incorporates a zobel network for the woofer and 18 db/octave tweeter crossover. Your best bet is to find someone who knows how to modify crossovers.

Main upgrade is Inductor coil, looked iron coil low end part, changed with air coil high quality wiring. Good video.
can we have a demo of before and after mod?
great mod! more videos like this plz...

Hi Dennis, the air core inductor is .80mH and the red capacitor is 10 uF. The coil is glued with hot melt glue.

Hi - One more question - did you change the crossover design in this video, or simply replace the components with higher quality parts? Thanks.
Can you link to the parts you used? I bought a used one and its a bit hollow and feels like there are some echos. I have no technical skills or way of knowing what is a good quality piece or if the numbers mh need to be the same or not.
You can find the inductor at partsexpress.com and the cap at mouser.com
I've blown a driver on the BR bookshelf speaker. Do you know a 4 inch driver i could replace it with?
You would have to replace both. Measure the parameters of the good one.
Love the video, but if I change the tweeter type do I need to have a diffrent crossover or can I just mod it like you did yours.
You would have to redesign the tweeter section of the crossover.
@@patricksuckoo232 thanks. Im still learning the basics, I appreciate your response.
Hey man, how did you know the value of the inductor? Did you take it out and measure or do you have any formula based on those capacitors and resistors?
measured
@@patricksuckoo232 nice, thanks man
Anyone e know what gauge the new inductor is? 14 or 18 awg? Huge difference in price. Thanks.
18ga

@@audioupgrades7759 i see, Is there risk of ruining the speakers?
@@lamecasuelas2 No really if you do everything correctly.
