This is where the know-how factor of enclosures comes in, the Man of Art, the one who knows how to draw the quintessence from a sheet of paper weighing but a few grams, without adding to it any distortion on any of the audible frequencies.
Be curious; listen one day to the LEMDA enclosures from the French builder STRAD AUDIO, which we designed.
It goes without saying that by full-range loudspeakers we are talking about loudspeakers whose resonance frequency is below 40 Hz, with a high response of at least 15 kHz, and a minimum efficiency of 94 db/W/m.

One must have listened beforehand to a pair of full-range loudspeakers in order to understand that musical reproduction is not merely a question of bandwidth or an elevated sound level, but rather that in the grooves of numerous vinyl records or CDs, there exists information that only full-range loudspeakers, and some rare and very elaborate multi-driver systems – and, therefore, extremely expensive – can restore.
Using an elaborate electromagnetic motor rather than a simple one is a choice that, as much in terms of reliability as of musicality, relates to level requirements. The technical reasons are numerous and well-known. We have as yet to master this technology which may present unwanted defaults.
This designation incorporates the joint application of several exclusive principles. Their execution is particularly sensitive and requires working with high-precision machines. Complementing this is an indispensable manual finish requiring an agility with regards to the requirements of the design concept.
Evolving from our initial technology, HPMF II was first developed during the creation of the LB7, the most successful full-range loudspeaker in our series. Creating a loudspeaker capable of reproducing an extra-large frequency range that is distortion-free, with merely a single 7-inch membrane, has been at every turn a constant challenge. We had to develop new principles and improve on others. This technology will be applied to future high-end prototypes that we are working on.
A choice that defies all modern methods. And yet, after testing everything else, no other material gave us as much versatility and, in the end, such musicality. Certainly, the option of using other components not excluded but, for the time being, we believe that cellulose paper membranes are simply the best elements for a full-range high performance loudspeaker, and for a long time to come.
A final point which exemplifies us, and by no means the least : we always favour the end result to a look. This is what allows us to offer products of an exceptional level at realistic prices. Our loudspeakers may not all be aesthetically pleasing, but they are all highly musical. Of course, we won’t exclude the idea of developing limited series which would include an aesthetic design concept; however, this aspect is not a priority for us. Professionals who build enclosures around our drivers are highly successful at this task…
has tested numerous methods, some of which were quite superior in terms of musicality. However, an undeniable factor brought us to eliminate these solutions : reliability. All our loudspeakers are made to last. Because of this decision, you will never find, for example, exotic mountings or foam suspensions in our line of products. Our prices are justified by the investment in a superior high-quality product made by the buyer, whatever the criteria.
Furthermore, technologies developed for electromagnetic motors have allowed us to reduce basic principles for conventional loudspeakers that, in turn, benefit from this improvement. The application of these technological principles was named as follows :
All loudspeakers use HPMF technology.
developed a know-how and specific technologies that allow us to obtain an absolutely perfect and homogenous magnetic flux, in which is found a complete voice call assembly. The results are astounding reactivity, stability, and damping that only some rare drivers are capable of offering, regardless of the manufacturer. These qualities, of course, are observed while listening. Certainly a perfectly optimized electromagnetic loudspeaker requires a stabilized power supply (built upon request), but this is its only restraint.
Proud of having participated in the writing of some of the most impressive pages ever produced on High Fidelity thanks to its full-range loudspeakers, is currently at work to find a solution for enclosures using a full-range loudspeaker supported by a bass unit below 100 Hz and a tweeter above 10 kHz. Optimized as of the design stage, this minimally filtered configuration will unite the advantages of full-range and those of multi-driver systems, while avoiding the better part of their respective inconveniences.
