What is the impact of the proximity of speakers to the input jacks on signal

[kraal]

Hello,

I started working (for fun) on a small amplified audio probe (with speaker and 4mm banana jacks to plug probes) that would fit in a Hammond 1590a enclosure. Something similar to [1].
As there is little space in 1590a enclosures, the only way I found so far in order to stick everything inside the box is to have the banana jacks right below the speaker (2mm below it).
In your experience, would such a proximity cause issues / too much interference when probing ? (I don't have the speaker yet so I cannot test)

Here are pictures of what I'm planning to do.





Thank you in advance for your feedback!
