It's been five years since I only use ART300 and 300A.
Quality: high-performance, clarity of the medium (some would say 'aggressive', but here is controlled), very reliable
I praise is they go hand in all 5 years.
Interviews the most frequent replacement of the bulb to protect the tweeter on the model 'passive'.
A plan after hundreds of transport: replace resistance porcelain filter.
NOT A SINGLE tweeter has dropped since I have them.
From time to time a 12 "tired Recon (Recone kit € 87).
But I consider all these costs negligible given the enormous profitability of these speakers (5 years = about 200 services / room!)
For a home user who has the care: having any hassle.

For the occasion, the opinion of yo-yo on the forum is more than good!

Check the box, listen to high level, be sure that the components are original (here is more difficult), if the seller is serious, he will not hesitate to give you a guarantee. For example: the 12 "has a huge magnet, typical of FCR.

I did everything with these small forms of speech to rock.
Demand for low FCR ESW1018 I add.
The most popular configuration: 2 x ART300, 2 x ESW1018 on amp Kind XT3000
Simple and effective for booms and small concerts (200 to 400).

Go for it!
