Advice on Sony 3 way speakers without crossover

I'm going to stick with my original suggestion 3.3 uF.
It's a subjective vs objective argument.
After 10khz, what is the roll-off in a 50-year-old man's hearing?
Beauty being in the eyes of the beholder: response doesn't have to BE flat it has to SOUND flat.
 
Wow!! I really stirred that pot LOL😳. And got scolded for it, LOL.😳 Perhaps I should have clarified. The amp volume was only set to 5 percent-less than 10 percent and although still quiet I could hear it clearly, I estimated the potential loudness based on the volume setting. so no need to bust any testis but I appreciate your concern.
Will this do? Altronics is my only close supplier. https://www.altronics.com.au/p/r6520-lelon-2.2uf-50v-pcb-bipolar-capacitor/
I can purchase a variety of them and go to town with experimentations.
 
Wow, and to think all of this appears to be nothing more than some bad caps > dead before their time 😎

I would buy 4x 4.7uF and make two pairs of series joined caps. > giving you two final caps of roughly 2.4 uF.

Here's a video about another small Sony speaker, much better, but still cheap >

Can't hear any thing above 8000 Hz unless it's really loud. Tinnitus is between 4500-6000 Hz.
 
At low to moderate volume levels 3.3uF might give you nicer clarity, given your hearing, but
it may actually push the tweeter outside of its reasonable range. (it's only a first order XO)
At higher volume levels, you don't want to blow your tweeters only to start a new problem.

That store has practically nothing of capacitors. 🙄
Don't take those bipolar elko, they're miserable.
Buy these MKT 10pcs, start from 2uF (1+1 in paralel), then add 1uF, then another 1uF, don't go over 4uF.

Since you unfortunately have hearing problems, you are not a good candidate for that game, but invite someone to help you evaluate the results.

Yeah You're right, they don't have a lot to choose from, so I'll grab the 1uf 10 pack and keep adding in parallel up to no more than 4 until I'm happy.

I prefer using electrolytics for testing, they're more practical being light and easier on the leads when handled often. They are readily available in larger values and are inexpensive to replace. I don't have a problem with sound. If ESR is a factor it's not enough of a problem to prevent me getting useful data. If I damage the casing on them I'll throw them away.

Hi guys . How are you ? I just got pair of flx9 speaker and tested it with original sony s9 amplifier . It sounds very better than s9 speaker . I think basically these 3 pairs i test are nearly same . Sony s9 dp800d flx9 all of these just have a simple capacitor . May i ask is there a simple crossover that i can make for getting better sound without measurements ?

I think s9 speaker isnt 3 way its a 2.5 way or same az flx9 .
I can make inductor and have access to normal capacitor.
 
Okay so after some experimentation I ended up placing a 2.2uf cap in parallel with the existing 1.8 giving me a total of 4uf, and omitted the other one. I was going to just use one 4.7uf but I didn't want to go into the danger zone.
OMG!!! the results are nothing short of remarkable, I would never have guessed that a couple of uf could make such an improvement.

I wouldn't mind trying to give one of the woofer a little more bass just to off set them slightly.

If by "off set" you mean the top-end is a bit too bright > I would drop 4uF back to 3.3uF . It is also a safer value.
Because your woofers are in parallel, as they should be for max. output > to increase bass
just use that old-fashioned thing called a 'Bass Control' - if you have one 😉
It's great to hear of your successful improvement.

I would say put the standard value of 3.9uF. Don't go for 4.7uF it will sound too bright. Take care that now the tweeter works a whole octave lower than before, so it gets more power. No parties or such, just normal use without overdoing it. I suggest Mundorf EVO Oil 3.9uF as a good compromise between price and quality. I got them on ebay.
