It's not a 2.5. SS-9 & SS-3 are 2-ways. There is no inductor. If you attempt to put any form of high-pass filter on the mid-range the low-frequency response will suffer. Below the filter frequency the 'mid-range' will act as a passive radiator. Subsequently, the port will be incorrectly tuned.
Seriously, there are five pairs Sony speakers in this room - I know of what I speak.
One driver is optimized for bass, and it stops working earlier, probably that's how they compensated for the baffle step. The second is bass/midrange, or something like extended range, which covers the mid range and part of the high range. And then they added a tweeter to cover the higher end of the spectrum. Such a conception is most similar to 2.5 way.
It's 2-way. The fact that the drivers have different dust caps is irrelevant.
If I had a 2 x 12 guitar speaker, and one Fane driver failed and I replaced it with an Eminence driver - it wouldn't make it 2-way!
Hi . Can you see my posts or im invisible ?
I have 3 pairs of sony. One of these is s9 . I will be happy to try and examine cross over and share the results with others but please if there is a reason that i cant see any answer on my post tell me clearly. Its last time im asking lets think we have an s9 speaker . In user manual it says one tweeter one woofer and one subwoofer.we have 2 condition without measurements.first that woofer and subwoofer are same in that case i think it will be 2 way . Second is that those two are different in that case we are 2.5 or 3 way . My question is if you have these speakers without measurements and had acsses to capacitor and inductors do you use crossovers for s9 or not ? Can i do some test for measuring with phone to detect if drivers are same or what ferecuncy had or not ?

Is it my responsibility to advise this genial man that he's hi jacking my thread and that he would have more luck if he started his own thread?
So the final result is amazing. I'm using the 4.0uf for now, we don't do parties, and I've filled the inside of the box with left over sound insulation.
The test music that I used is Santana, eternal caravan of reincarnation, lots of high's mid's and bass. I can hear every thing clearly.
Not the same $20 speakers. Night and Day.
Thanks for your help guys.
What difference will I hear with these caps?

Its not a 2,5 way unless crossover is. Does 2,5 ways need seperate cabinet volumes for each driver?
Cheers!
Cheers!
Sorry Allen.That was a genuine question. Was trying to be helpful.

Hi guys. How do you do ? I don't want to hijack anything im sorry if there is a misaunderstanding just bought s9 speakers last week and want to be with walcen in upgrading. Im from iran.here is a mess a pair of these speakers cost about a month of avarage income. My uncle has a wiring workshop that i can get inductor almost cheap.i have 3 pairs of sony in different boxes that i can test sounds learn and share results.in these 3 speakers we have same tweeters but 3 different sounds and none of has cross over .main question is if we have only 2 woofer and a tweeter without measurement what can we do ? 2 way 2.5 way and 3 way scenario. Is there a elementary way to seperate ferecuncy or just use these as they are . I apologize about my English.

They are too expensive, I used to get them for almost half the price. That's why I recommended them. I will look for something cheaper to replace those electrolytic ones.
These capacitors sound proven good. Buy 10pcs, use 4+4. I often use Phillips 1uF 100V MKC in speakers and other audio equipment, which I get locally very cheaply.

These are 1uF 400V and physically a bit bigger, but I think they can fit in that box. It just needs to be attached to the box somehow, probably glued.
If you find a Phillips MKC 100V on ebay, feel free to buy them.

According to that logic, this Sony is not even 2way because its crossover consists of only one capacitor on the tweeter, so it is 1way. 🤣
Crossover is an electrical correction factor for the acoustic output. If you design the drivers in a specific way, as done here, you can get by without a typical crossover, you just have to put a capacitor where necessary to protect the small drivers from low frequencies. Acoustically, this is 2.5way, because at the lowest frequencies two drivers work together, then only one of them continues and finally the tweeter takes over the highest frequencies. This is achieved by using different motors and dust cups on the the cone drivers, they are not identical.
Let's say with the so-called full range drivers, there are examples with whizzer cone. Basically they are two acoustical radiators, the larger cone works up to a certain frequency and slowly stops emitting sound, and then the rest is taken over by the whizzer cone. Acoustically, it is 2way, with mechanical separation of frequencies achieved by the different constructions of the two membranes. At low frequencies, both membranes work, but the contribution of the whizzer zone is negligible due to its small dimensions. As the frequency increases, the large diaphragm emits less and less sound, and the whizzer more and more.

You are giving Sony way too much credit. I don't believe these speakers were available as separates. They were bundled with hi-fi systems. The focus was on cosmetic appeal. Having taken several of these speakers apart I can find to difference in the drivers except the dust cap.
If you take the speakers for what they are: 2-way with twin woofers the seeming 'dead' top end is logical. By installing another woofer into a 2-way design you increase the bass-mid output by 3 to 6dB. Subsequently the tweeter sounds dead by comparison.

"Hmm Not quite identical, one speaker has a significantly longer voice coil than the other."
I bet a measurement would show they have quite a different frequency range. In the end, it doesn't even matter if he's happy with how they sound. After all, they are cheap commercial speakers to invest a lot.
I've rebuilt factory crossovers sometimes, for friends, but I have measurement equipment and plenty of parts for testing, so I mostly know which way to go. Changing factory solutions remotely like this is a bit awkward. 🙄

OK so its a "2,5 way on the cheap" if you insist. I just feel you are muddying the picture for everybody by this insisting. I think many cheap speakers are great candidates for modifikation, as OPs results have already shown. "Too cheap to bother" is misused and a misunderstanding that other people have another financial situation or desire to try something for learning than one self.
Cheers!
