Good to see your attempt. Shame it was not the Neo3, its not quite as easy here, as nobody stocks the latter here in the UK. So I may have to pluck up my courage and go for it !
Where bass drivers are concerned, the Alpha 10, looks a better driver for the reasons Wayne has made. Also if you look on the "Prodance" website, you will find both drivers tested. The "10" looks quite a bit better, with the specteral decay, much cleaner, less break up. From what I have seen the 10 has a response at least as good as many more expensive HiFi drivers. It may loose out at the bass end but gains in sensitivity. All a compromise
