"Although there are a whole range of interesting speakers for converter principles are direct emitters dominate all other designs: More than 90 percent of all boxes set with the sound funnel or dome membrane predominantly forward. ... An interesting alternative to the widespread is the Kalottensystemen 4Pi tweeter of ELAC, whose circular membrane from a jagged aluminum foil ... the sound horizontally in all directions equally loud abstrahlt. "

"ELAC manufactures such round spotlight since 1984. The latest version, in the brand-stander FS 608 is used to be ultra-strong Neodymmagnete thanks to the previous 5 decibels more efficiency and achieve up to 50 kilohertz sound recoverable deliver ..."

"Below the frequency of the ring radiator, which at 4 kilohertz is coming dynamic drivers to use ... The box as a whole is therefore a mixture of round and direct spotlights. ELAC wants this construction with the advantages of both worlds together ... This ambitious goal requires a series of tricks, ranging from a sophisticated crossover to the design and layout of the chassis. "

"Even the 608 is mechanically a very elaborate construction dar. The well-housing based on a different material from aluminum elements and MDF, which is extreme rigidity and resonance poverty promises. Horizontal and vertical bracing suppress remaining vibrations, additional Zugstreben ensure constant tension. Compared with a conventional Wood offers of housing construction in the same external dimensions significantly more interior volume, which is the efficiency in the bass range benefit .... amazing deep lower frequency limit allows. "

"The extremely slim boxes corpus is out of the box with a sturdy metal screws, which alternatively height-adjustable spikes or rubber feet seat.

"If it is the exciting question of how such an unusual mix of direct and some sound-emitting sources would cut phonetically. To anticipate it: all excellent."

"... the ELAC met the sonic character of a concert grand piano or a delicate female voices very convincing."
"What the FS 608-4Pi from their two only 18 centimeters wide Alutreibern to control pressure and sought out, bordered almost on a miracle."

"The best part of ELAC FS 608-4Pi however, is its mix of completely unagressiver dynamics and striking Luftigkeit - that is so fast it no other box after it."

Ruling:

"Beautiful form stander with radial tweeter in combination with a conventional assembly. Large Figure in good Detectability. Traumhaft hearted and airy, basspotent enormously."
