HDS tweeter monitor upgrade
At the time I completely finished my ultimate monitor, Tympany had their new HDS 1" tweeter ready for sale. Since I'd like to change my system to the 'ultimate Peerless' and also because I was very curious about the quality of the new HDS tweeter I ordered this very nice looking product. Once I developed a proper crossover, the tweeter stayed and can really be considered as an upgrade of an already excellent system. I listened to a lot of systems the last few years, be it commercial systems or DIY. I have come to the conclusion that for me, given the sound of my ultimate monitor together with the dipole bass and closed subwoofer, there is no direct reason to further improve or change to another concept.
If my ultimate monitor is placed upon the dipole bass, it shows the response below. Depicted is the horizontal dispersion at 0 degrees (black), 30 degrees (blue), 45 degrees (red) and 60 degrees (green). From this graph you can see that the tonal balance is completely neutral up to 10 kHz. Above that frequency the tweeter dispersion dominates the response.
