 Mr.Bernard Salabert より



If you listen to the 21 cm in comparison to Lowther , Supravox , Fostex , you'd probably change your mind ;

same for interconnects and speaker cables ; may be one day ... all people who try , never want to give back ;

Regarding cabinets :

We do not know any cabinet kind giving good results as the air enclosed in a cabinet,

even decompressed by a port , is mecanicly a spring attached to the cone and so destroy a lot of qualities

 , so much that , if it can be acceptable for a bass unit in a multyway system , it is dramatic for a wide range ;

And as you can let the folding baffle folded as a triangle and open or not or plus or minus for listening ,

and most of clients let it closed , only opened at the top = not far from bass reflex

 ( but with a very low and light accord ), so it is a thin column only 30 or 40 cm wide ,

much more little than any kind of cabinet ( br , tl , horn , onken ...) ;

as it is 3 simple boards assembled with piano hinge , it is very simple to build and sand ,

and finishing is also very easy by hanging it with a beautiful cloth stapled on rear ,

important for sound ( boarder effects ) , to listen music ( beautiful sounds nicer ) in living room to live with ,

and/or WAF ; other important points are that if you respect our drawing you will 100 % get good results

without any important mistake , at the opposite of any classic cabinet kind ,

and that it gives a unique hudge range of easy tuning by opening plus or less or/and moving plus or less

to the rear or/and side wall ; regarding horn , it is not possible to make a wide range horn ,

so you will put plus 3 dB mini in an area and not in an other one,

and this is a pitty as for once we have a unit which is very well balanced from 30 hz to 30 khz
