Hi, I have a Toshiba RT-F452D mono box which unfortunately has a really poor tweeter. I was wondering if it is possible to somehow replace it with a better tweeter? Any advice much appreciated.
Cheers.

Ugh! The dreaded piezo tweeter. I'd say just about any tweeter you can make fit would be an improvement. :yes: Would it be worth it? Ehh... not sure.

Its always worth it! Some car stereo speakers might have the size you're looking for. Look on Amazon and pay attention to the dimensions. The space looks decent for a replacement.

I did have a look at some car stereo tweeters but they seem to be rated at quite high watts I was unsure if they would work properly in my mono box?

You could put a coaxial car speaker in there and that would probably sound a lot better.
Look for a sensitivity rating of 90 db or above and it should be pretty efficient with power.

I have had success with 8 ohm minis like this they only cost a couple of dollars each.;

Mylar diaphragm speaker for replacement use in Telephones, Headphones Intercoms and also suitable where moisture is present.
- Mini Size : 27mm Diameter
- 9mm Thick
- 8 0.25Watt
- Frequency Response: 30 ~ 18 KHz

The original looks like a Transducer = useless

Hi Floyd, In that case you have to send it all to the main speaker bipassing the crossover circuit right?

Actually I was thinking just replace the woofer with a coaxial car speaker. That way you upgrade both speakers in one shot.

Update, whilst having a sort out I found a whole bunch of these minis that came in bird song christmas crackers from last Christmas. Being the sort of sad middle age man that I am I put one into my radio today (Christmas eve) and to my surprise it works very well, it even fitted in almost perfectly without altering anything. The new tweeter does distort and start clicking at just over half volume but I don't listen above half so its not a problem. The last photo shows the crappy transducer that was originally in the radio which was indeed useless.
Merry Christmas.
