NOMEX 164

Peerless HDS164 Nomex 830875 + ScanSpeak D2608/9130

I think these drivers deliver an excellent cost performance ratio and I was really surprised when I made the final set-up in our living room driven by my JungSon class A amp. I usually make my test crossovers from Superior Z-caps, good baked coils and 10 watt MOX resistors and all in all these drivers makes me wonder why I ever spend money on "high-end" drivers. These NOMEX drivers have an excellent midrange presentation and if you're seeking a driver that will handle vocals with grace, try out these drivers. Click heading to go to construction page.

Peerless HDS 831882 and Vifa XT25TG30-04

An excellent midrange from Peerless 5.25" HDS drivers.


Peerless mini, HDS134-PPB (830860) + Vifa DX25TG/XT25TG

Time for making a substitute for this construction, thus the HDS-PPB version (838060) have been set up with either DX25TG or XT25TG tweeters. 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.

2 x Peerless HDS164 (850438) + Vifa XT25TG-30-04

This construction comes very close to what I had in mind for a 2-way with the intended features. These speakers will play anything with a wide soundstage, some really good bass and with excellent midrange transparency. Getting the XT25TG tweeter level right is - as always - very important. I have found the 1R5 resistor to the tweeter to give the best results. Usually I start with a too high tweeter level and slowly increase attenuation until a level where it just seems to "disappear", i.e. it gels into the overall sound without making an act of itself. It's a pity Peerless has discontinued these sandwich diaphragms. I hope the new Nomex and PPB cones (see below) will work as good as these do.

The HDS134/DX25TG has a very flat response profile and the overall sound is a little more right in your face compared to the Koapong. The HDS134 is indeed a very good driver considering the price and I have no reservation in recommending it. The speakers throw a soundstage that defy their size and with the chosen cabinet volume and vent tuning even some decent bass can be heard. The final cab images are borrowed from Steiner.
