On both HP is a three-way, used exclusively for the homestudio, they do not déméritent hifi.
Construction serious hp protected by a metal grid that vibrates ever!
Double terminals for bi-amp!
Are arch-neutral?, Not sure, but it is the opposite of an NS10! I meant, the DB17 that sound beautifully despite their size, the sound is big, very friendly never tiring! beautiful opening of the soundstage, but it depends on the amp too.
They equip my home since 21 years, associated with a Alesis RA100 amp, and my faith! constantce in the operation is to be welcomed, they are very well built.
I like the sound reproduction Lots purchased, can sometimes be flattering, but the emotion is there!
