Specifications for 'biline' Speakers.
You might be wondering what these biline speakers is all about, these were a set of speakers I had constructed and was seriously considering bringing to market I had built and sold close to 50 pairs of these speakers just through 'word-of-mouth' and they were designed to fill a need at the time with the poor choices of 5.1 speaker systems that were available to the public the only decent ones were 'Thousands of dollars' and mine if the user was willing to do some work would have cost just under One Thousand dollars and were easily equal to those Five Thousand dollar systems. I built the bare cabinets and the user built the speakers and finished the cabinets in the stain of their choice. The cabinets were built using Medium Density Fibre-board (MDF) with real birch Veneers. The Crossovers was very simple due to the excellent drivers used and the fact that the drivers themselves had very flat frequency response curves. The speakers also used an array that was originally discovered by Joseph D'Apploito called the D'Apploito network array. It was two regular drivers with a tweeter located in the middle between them so two drivers (bi) in a line hence the bi-line name.Why does 'biline' Use 'Vifa' Drivers?
First some History is called for:
Vifa. Established 1933. Is situated in Denmark. Vifa is an international company. Represented in most countries. They export 90% of their production to technically demanding countries all over the world It has always been Vifa's aim to hold a position among market leaders in the field of hi-fi drivers. And their research and developing department is always busy carrying out a multitude of projects on new principles and materials. So as always to be up-to-the-minute on technological developments In order to fulfil this aim they make extensive use of modern computer technology. For example FFT (fast fourier transform). Cumulative spectra (3D plots), Computer simulation and Cad systems for the design of new components.
The Vifa design philosophy is to develop drivers with an excellent price ratio through optimal use of materials and principles. Vifa does not only care about the drivers performance in the piston range and with small signals. But they also put great efforts in controlling for example a woofer response way up in the midrange frequencies. Another example is woofers specifically designed for bass reflex enclosures. Where the large signal behavior is optimized over and even below the tuning frequency. Vifa produces high quality speaker units only. And their product range comprises well over 300 different types, 75% of which are custom designed. Developed to meet the specific requirement and wishes of individual customers and often developed in collaboration will the companies own engineers.
At Vifa they focus on their customers. And therefore they go for solutions. Which are to the advantage of the customer-and please note: Vifa is not in competition with the customers, as they only produce high-quality drivers. Not speaker 'box' or kit's as most of their competition does.

I'll be honest the 'biline' speakers are not the BEST speakers you could purchase or build, there are many other Brands which are as good or better, 'biline' is a custom built speaker produced in small runs (usually 2-4 pairs at one time) I created these speakers for one reason for 'Home Theatre'!, I did not have the Funds to Purchase an acceptable set of 5 speakers!, After lots of research and the help of my Cousin 'Marc Dugas' (he builds and repairs all makes of Speakers and Drivers) I decided to use the components he Suggested (which are listed above) And the first run was made. The results were very impressive, I don't like trying to write about how wonderful the sound was, suffice to say anyone who has heard them has asked me to build some for them (to date I have built over 60 pairs). Some individuals have even started construction on a set for themselves, I am quite willing to to provide all the information required to build these speakers and will hopefully have a complete guide up with diagrams and some pictures in the near future.
If anyone wants more information on building these drop me an e-mail
