The Interior 330 is probably the most balanced speaker of this good series. The sound is warm and pleasant. The bass is punchy and the three-dimensionality of the music is also noteworthy - with good depth. The metal domes are in no way obtrusive, which is often the case with other models and manufacturers. It is suitable for all kinds of music - a so-called all-rounder.

In many tests the speakers came out as WINNER. In the audio they were, if I remember correctly, classified in the upper class, in Stereoplay in the top class.

Depending on their condition, these speakers are priced between 60,00 and 180,00 Euro. They are worth this money if the surrounds and the diaphragms are in good condition. But this is usually the case, because Heco built really good speakers back then.

Special Features ISS - stands for Integrated Subwoofer System, both speakers have their own low bass presentation. Therefore Also 330 S
