Top Quality 5" Studio Reference Monitor

Build upon the legacy of our famous nEar05 models, the new aktiv 05 near field reference monitor take professional level 5" near field monitoring speakers for the entry level to yet another level.

The monitor boasts an ultra-flat low frequency response with its newly designed larger silk dome tweeter and the top quality kevlar 5" driver delivers unparalleled punch in the low-mid frequency - a major improvement over the paper and polypropylene drivers used in most comparable products. ESI was the first vendor using kevlar for studio monitors in this price range as material inside the low frequency driver. Other vendors have since copied our idea, however there is much more to excellent sound of aktiv 05. A new tuning of all components by our engineers in Germany and the use of the completelely new crossover design, turn aktiv 05 into yet another milestone in the ESI studio monitor legacy.

Optionally an aktiv 05 based monitoring system can be expanded with a subwoofer like our aktiv 10s. aktiv 05 is the perfect alternative to our higher end uniK 05+ reference monitor if you are on a budget.
