what do you think about this one? https://faitalpro.com/en/products/LF_Loudspeakers/product_details/index.php?id=401040100
Have you thought about bi-amping? You could keep the aesthetics original but have a wider choice of drivers. Possibly use DSP with a dedicated amp for the woofer.
It does not matter if Sansui or someone else stuffed the reflex tubes. With no stuffing in the tubes the bass reflex effect will increase bass output and reduce cone motion at the cost of worse transient response. With stuffing in them the system will work as a closed box with a slight leak if it is stuffed really hard. With less stuffing the vent will introduce resistive damping (used with drivers with to high Q or to small boxes). Look up "variovent".
You have to sort out the current system before heading into driver replacement.
35W to powerful? Are you sure you are not clipping the amp and blame the speakers?

Adding another with tone controls to drive the amp completely separately might be your best option.
A higher Qts indicates it should work well in a sealed enclosure.As a rough guide anything with a qts above about 0.45 will tend to work well in a sealed enclosure.
If you alter or change anything they would become valueless as a collectors piece and probably wouldn't sound any better. Why not just add a decent subwoofer? If adding a powered subwoofer is not in the budget then add in a .5 woofer with better bass using the best inductor you can afford, if height is a problem using the new woofer box as a base then perhaps dual 12" woofers side by side but Bi-Amping or a powered sub is probably a better option if you can afford it.
I thiink that you would need at least those two 12" woofer to get the efficiency you need and because high value inductors with low resistance are very very expensive a few dirt cheap FOSi sub amps may be a better way to go, here at least these amps cost much less than inductors

Thank you for the replies.
I want to ameliorate the sound with the new woofer from 600 or 700Hz and down. as the sansui woofer does not provide good clear sound on the lows.
I would also like to test the vintage woofer drivers in larger box too see the difference by curiosity.
I have never used a setting with subwoofer. I always liked the stereo system. I don't have experience of that.
What do you mean "in a.5 woofer.."?
If using 2X12" as stereo separately could be good solution on separate amplifier, what do you suggest
Thank you

A .5 woofer can be thought of as a "Helper" and it uses a very large inductor so only the low frequencies are seen by the supplementary driver.
It reduces the excursion of the main bass driver.
Often used to give more bass to a 2-Way speaker but can be used to do the same with a 3-Way speaker. I suggested using a pair of [2 * 12"] so that there would be a 4R load which could utilise a smaller value of inductor because sometimes 2 budget woofers can be cheaper than one good quality 4R woofer and high value inductors are very expensive and around here used 12" seem to be cheaper and more of them around, also a box high enough for a 12" raises the older box to the right height many times
An alternative is getting a cheap electronic crossover such as the Behringer CX2310 (cheap second hand if possible) and a separate small second hand power amp, I do this as being cheaper than a pair of powered subs

.5woofer I guess you mean a 5" woofer for extremely low frequencies? to add on the actual system with a separate amplifier?
can you show me a photo of a 2*12" to have a idea?
Do yo suggest a pair of 2*12" in parallel giving 4ohms impudence ? how would I wire this on the system?
Thank you
