Small full range closed back vs open back without enclosure effect on audio


My bookshelf tweeter was not working fine so i tried replacing it with same specs but instead of 2 inch I replaced it with 2.5 as my cabinet had more room also 2 inch was not available at that time.

What I noticed is my old tweeter had closed back means spider was not visible, were as this tweet has a open back i can see spider.

So will it make any issue like, moreover

woofer is in different compartment there will be not much air pressure only vibration is a issue they might interfere with my tweeter or not i don't know.

If it is bad so I can replace with closed back one or return this 2.5 inch tweeter and try finding closed back tweeter

Thanks in advance

The difference between a closed-back and an open-back driver lies in their design and how they handle vibrations and sound waves. A closed-back driver is enclosed, preventing sound waves from affecting the backside of the driver. This design typically minimizes interference from vibrations and external factors, maintaining a more consistent sound output.

On the other hand, an open-back driver allows sound waves to pass through both the front and back, potentially leading to interference from vibrations or sound waves bouncing back into the driver, affecting its performance or causing distortion.

So, while adjusting settings or equalization might help compensate for certain differences in response, the inherent design variation between closed-back and open-back drivers can still impact how vibrations and sound waves interact with the driver, potentially affecting the overall audio quality.

Have you tried this?

Attached, Kamranbits, is your original photograph of the enclosure.

The 2.5 inch "tweeter" looks like a small full range driver.

The enclosure looks to be badly broken.

I'd be interested in seeing the entire enclosure in more detail.

In this case the sound from the back of the 'tweeter' can reach the sound from the front of the tweeter. It will cancel itself. That is why the original tweeter was closed on the back - so the back sound does not cancel the front sound.

However these speakers do not seem very 'high-end' so I think the important thing is you are happy with the sound. If the new tweeter is too loud you can try adding a resistor in line, or a resistor network called an L-pad or voltage divider.
Sound is good but will that cancellation effect audio? I don't see much change just vocals are high but can manage also you can see that is glued to cabinet what I was thinking to take round shaped plastic pieces and screen one side of it to twetter and glue other side to cabinet is that ok ? Or this current glued setup is ok
