|The excellent sandwich cones of previous HDS134
drivers (850488) are long time gone and it's time for making a
substitute for this construction, thus the HDS-PPB version (838060) has
been set up with ScanSpeak D2604/830000 tweeter.
Most small 5" drivers have relatively high Fs and I was curious to hear what this driver could make from ~8 liter cabinet volume and a port tuning of 55-60 Hz. Well, as if often the case we may be surprised from the bass performance of mini speakers and this PPB driver is no exception.
What came as an even better surprise was the quality of the midrange. Smooth, clean and very tolerable towards vocals. No nasty cone break-ups, thus I made cumulative spectral decay measurements as can be viewed below. This driver would do excellent too in a 3-way system.
For a low-cost mini, this speaker is highly recommended. The DX tweeter response may look a bit uneven, but nothing noticeable at all when it comes to sound. The XT provides smoother response - at higher cost, so take your pick. Some people love the XT, some don't. I think this has to do with the somewhat different dispersion characteristics of the XT.
