Ive had the D1 for about 2 years.
Then I had the thought of radically changing it (nag sawa lang sa tunug) - I had Anthony repalce the tweeters with radiators, and so far so good.
But of course, best to audition muna.
Both D1 and D2 speakers are good in their own way in their original configuration.
Modified crossover and tweeter - Sorry camphone lang
Current placement - Sorry camphone lang
Cheers:)
