Hi thanks for viewing my items for sale Im selling four scan speak Revelator midwoofer drivers all drivers have been tested and are in great work conditions these drivers are being sold individually I originally picked them up for a project but they didnt work for my build any questions feel free to contact me thank you Qts version -01. The 15W/8530K is a 5 ½ Revelator mid/woofer. It features a non-resonant cone and dust cap structure, dynamic linear suspension, SD-1 magnet system, Grasshopper cast chassis with maximized airflow and resonance terminating mounting system. Less resonance in all structures, lower compression and higher linearity, faster termination of excess energy, and higher sound pressure capability make the 15W have more musical and dynamic capability than any other 5 ½ we know of. Wonderful bass in a small box!

Diese 15cm Tiefmitteltöner gehören zu den besten ihrer Art und sind in legendären High End Lautsprechern renommierter Lautsprechermanufakturen verbaut, die leicht fünf- oder sechstellige Summen kosten. Ich hatte sie ein paar Jahre in meinen Lautsprechern verbaut, bin nun aber auf die Scan-Speak Illuminator Serie umgestiegen - nicht weil sie besser sind, sie passen nur noch ein Tick besser zu der Musik die ich höre. Es versteht sich von selbst, dass ich diese wertvollen Treiber (Neupreis 200€ pro Stk) bestmöglich und sicher verpacke, damit sie unbeschadet ankommen. Sie funktionieren noch immer wie am ersten Tag und haben nie wirklich Leistung gesehen - bei solchen Treibern geügt Zimmerlautstärke und die Band steht im Zimmer...

It is a two way compact loudspeaker, and manages the brilliant feat of combining the tonal and spatial qualities of the classic compact two-way loudspeaker with the bass underpinning and dynamic deep bass performance of larger floor-standing units to produce a delightful loudspeaker. As with all TL models, the cabinets are extremely stiff and resonance-free, because they are made of a laminated wood material. For the mid-range/deep bass area the phenomenal GREYCONE® drive unit is employed; this has an extremely low bottom limit frequency with an excellent ability to cope with extreme levels. In the mid-range this speaker provides an incredibly free, open sound without any hint of coloration. Solid bi-amping terminals, an extremely low-loss crossover unit incorporating a new type of coil offering low saturation and distortion, and an accurately matched bass reflex system - these are the essential features of this faultless little loudspeaker.
