Hi everyone, I recently acquired a pair of Beovox 5700 speakers which I absolutely adore. I was previously aware that by this stage in their life, the foam dustcaps on the woofers would almost certainly have disintegrated. Amazingly however, both dustcaps on mine are fully intact and look in really good shape, bar one really small 1cm hairline crack in one. I'm frightened at the moment to feed too much power to the speakers in case this crack worsens. I was therefore wondering if there is anything I can apply to the dustcap to seal this crack and possibly preserve the rest of the dustcap? PVA glue perhaps? Also, realising that inevitably I will need to replace both dustcaps, can anyone advise me on where I can get hold of suitable replacement dustcaps, adhesive material, and the process involved in replacing them? Many thanks!
