What is a crossover less wideband driver?
There are no series crossover- parts before the driver in the signal- path and by this the driver is direct coupled to the amp for best possible control. A crossover less wideband- driver shows best possible detail and response because there is no loss of fine detail by any parts
What is a floor- firing bass horn?
It is an opening (horn- mouth) at the bottom of the speaker where the bass- waves come out produced by the wideband driver leave the cabinets after they have been transformed by the horn inside the cabinet. The floor- firing bass horns increase the dynamics a lot compared to traditional speakers because they act like much bigger diameter drivers. This is due to the much bigger surface of the horn- mouth. The floor-firing horns use the free floor space under and around the speakers as virtual part of the horn- mouth and so the speakers can produce fundamental bass and much higher dynamics compared to common speakers with same sized drivers. The floor- firing bass horn speakers react self- adjusting. Placed in a small room close to the rear- wall the floor- space under the speakers and around is smaller compared to free placement in a big room and the degree of the support of the horns is smaller. The floor- firing bass horn speakers won`t produce fat and muddy basses in small rooms and they won`t thin out and miss basses in bigger sized rooms.
What type of amp is best to use?
Any good sounding amp is fine to power the speakers! It`s a common misunderstanding that high efficient speakers require fly- powered tubed amps - it`s impossible that a powerful and fine sounding Solid State- amp which powers low efficient speakers sounds worse powering much more easy to drive high efficient speakers. On the other side there are many excellent sounding fly- powered amps and only very few speakers which are in 100% harmony to this amps. The high efficient speakers from the Club-27 line are great for this kind of amps. Beside the high efficiency of the speakers they are an easy load for any kind of amps and they show a flattened impedance- curve.
How to position the speakers?
The speakers should be positioned about 30cm before the rear- wall and pulled out from there in small steps until voices and solo- instruments rise in height and the image becomes three- dimensional. This behavior depends on the quality of the record and the electronics and if this position can`t be found the right distance to the rear- wall is where the midrange sounds best. The speakers can be placed relatively close to the wall and also relatively close to the listening- position. It`s also possible to place the speakers in parallel for wide and big imaging or to toe them in that the inner side of the cabinets is just visible from the listening- position to get the most sharp midrange- image.
The distance in between the speakers should be about the distance to the listening- position but this also is variable. The ideal position always is dependent on the room, on the electronics and on the personal preferences of the listener.
Which room size is best for what speaker?
The small Janis speakers sound best in small to medium sized rooms and they can be placed directly before the wall. The bigger speakers from the line can be placed in small rooms without producing boomy basses and they can fill even big room- spaces with beautiful sounding music and lots of dynamic- headroom.
