Hello Wonderful person, thanks for checking out our first Paraflex blog post!


Let's jump into some key notes and define what on earth is a Paraflex speaker box design.

The Paraflex Public Address (PA) loudspeaker family consists of subwoofers, midrange and full range loudspeaker enclosures for the Public Address. This documentation contains information about the Paraflex concept and concentrates primarily on the Paraflex subwoofer enclosures. What is Paraflex An HOQS Paraflex loudspeaker enclosure consists of two Quarter Wave Resonators which merge near their ends to share a single mouth. There is a Low Tuned QW/Horn Resonator section and a High Tuned QW/Horn Resonator section (LTR and HTR for short) with a strategic tuning relationship. The two resonators work in a phase aligned parallel mode yet with an aspect of a series-tuned topology with its "merge", including some shared volume, and a shared mouth. Although often described in bandpass terminology the cabinet's operation more closely resembles that of Compound Horn, and we can refer to them as a modernized Compound Horn variant. The multi-resonant nature, geometry, and phase interaction results in performance characteristics such as high efficiency, improved control over the driver's cone, and some directivity (rear-rejection) often extending across the cabinet's entire working bandwidth. The name Paraflex is a double-portmanteau derived from a few (two of the three) founding developer's company names (Paragon + FlexTech) and also Parallel-Transflex. All the Paraflex enclosure types (even our kick-bins, kick-tops and mid-tops) are based on the same Compound QW/Horn LTR+HTR parallel-series hybrid principle. 


We have tons of designs - each look and sound great with a range of key performance characteristics from eye candy to ultra low frequency extensions 

The family consists of a range in different categories and sizes ranging from 12 inch drivers to 21 inch drivers. But all with the Low and High tuned resonators.
