Hi all.
I have such drivers.
I decided to run them as midbass, 65-250 Hz.
And from this point of view, improve.
I'm not the first owner. The first one repaired, changed the caps (these are decorative parts) and spiders (but this is important). Perhaps the spiders are original or close to them. I did not send the drivers for measurements.
But I decided to improve them.
I know of a great many experiments with additional neodymium, which is either placed on repulsion to the driver magnet, disk, or attached around the main magnet. In all cases we have a decrease in Q factor and an increase in sensitivity. Increased sensitivity is always a plus, better sound.
The second modification is replacing the spider with a more rigid one. Because I only need midbass from the drivers. I know about the successful experience of the Rainbow company, in their line of vanadium, pro and slts, there were two types of woofers - one classic, they played up to like 53Hz, the second were kick woofer - and played 80-180 Hz or 80-220Hz, depending on what is written where . The only structural differences between them were in the puck, the spider was stiffer, and in the parameters - the kick-woofers had a higher Q factor.
I searched for information on Google for several days. Including many old topics I found here on the forum.
An additional magnet gives an increase of up to 3 dB; if used around the main magnet, neodymium gave up to 10 dB, but the effect is more pronounced the weaker the main magnet of the driver. The 800s have a large magnet. So is it worth the effort?
If the experiment is successful, I am going to extend the idea to mid-frequency drivers and woofers.
Does anyone have positive experience with this, and in general, what are your thoughts on this? I will be grateful.
