My new JB Premium has a very crackly sound, so I decided to get the speaker light kit and upgrade the backbox to 5.25".
I just got the standard Kenwood ones (I know I know, they are crap, but it's JB sound from 60 years ago and not a rock concert, so they should suffice and it's affordable).

I installed the lights and was playing without the backbox speakers because they won't come until this evening.
It turns out it's the cabinet speaker that emits the majority of the crackly distorted sound.

I need some help to fix that, ideally with a drop-in replacement. I don't need an amp - the machines run typically only on volume level 5 or 6, I just want no gramophone-esque or clipping distortion.

I found a link earlier in this thread to a lowpass filter: https://smile.amazon.com/gp/product/B009D9KHZ2/ref=ox_sc_act_image_1
would that help?
Or should I get another speaker instead, or both?

As said, if I can get a drop-in replacement that would be ideal and I don't want to spend $200 on a speaker that is not exercised above 5% of what it can do either.
I've seen some 8" ceiling full-range speakers. OR should I go with a dedicated woofer (I suspect they are larger in size) and the lowpass filter?

Thanks for the help!

Edit:
Amazon suggested these subwoofer on the LP filter page:

They are in a price range that's suitable for me.

So if i get that right it's actually not the higher frequencies but the low ones that trip up the cabinet speaker. So a LP filter won't do squat.

The speakers that i linked in the previous post, would they be able to handle that or are they still too small / crappy?
Or in other words, what, in your opinion, would be the minimal viable product? $50, $60 range maybe? Or is there nothing that will help in that range?
Thank you for your help!
And thank you for the tip with the EQ. I'll give that a shot if the cabinet speaker replacement route won't pan out!

Awesome, thank you for the recommendation!
I may try the pinball life one for the simple reason that i can put more crap into the order, need light sockets and such stuff and don't want to pay shipping for like 20$ worth of parts.

Is that one going to do better in a Bond? I'm more than happy to plop that one in. Just trying to get rid of the distortion, nothing else.
Edit: Would you recommend the 4 or the 8 Ohm version without amp.
