These loudspeakers are somewhat centered. However, when working with an equalizer it is amazing how deep such relatively small boxes can go. The foam beads become porous and disintegrate with age. Therefore, do not replace the chassis, but let them fix you again, have the beads repaired. The boxes are very heavy for the size and have huge crossovers. Since these small speakers already go quite low, they are ideal for a supplement with a high-quality subwoofer (up to max 200Hz).
