i have got one box "hifi sound project 2981l" made in Belgium in 70/80ties.

it is tree way and i would like to change the lows cone as it does not meet my expectations. unfortunately the lows cone was already changed so i cant find out the specifications of the original one. i just know it was 8ohms and the hole in the box is 18cm in diameter :confused.

the mid cone is: philips AD 50800 which has the frequency range of 400-5000hz

the crossing had 2 caps 2.2uF and 6.8uF both for 60V.

please let me know what is the highest frequency for the lows cone you think i should choose.
