Hi Guys, I picked up a pair of Infinity Reference 60 speakers. The voicecoils on the bass drivers are gone, so redoing the surrounds is not an option. I am trying to find the best solution to replace the bass drivers. The GRS cheapies are an option but the 8 ohm version is just to small, the 4 ohm version is slightly bigger and will fit and will give me an F3 of about 50hz, which is not bad but I then I need to change the x over as they are calculated on the 8ohm version. The other option I was looking at was the sb Acoustics but I would.need to vent the box but a.pair of them should work very well. The infinity enclosure is about 2.70ft3 so close to 75 litres. 8″ SB20PFCR30-8

I also have a Alcone 8 AC He, which should.work well in a 75 litre enclosure. I was thinking of using a 8 inch Dayton passive radiator that has an Xmas of 11mm with the Alcone, but I would.need to adjust the xo. What's your thoughts guys any advice would be much appreciated.https://www.lautsprechershop.de/hifi/alcone_en.htm
