Convincing and worth the money!
Viper, 25.01.2018
After a first theoretical preselection, this sub prevailed among various competitors.
Criteria were among others:
- Transportability in a private estate car
- Weight, so that a person can carry the sub alone on stairs or can load him.
- Flexibility at the crossover frequency
- Draft, so it really is an addition to 10 "or 12" tops
- Performance, so that not too powerful bass requirements, a single sub 2 can cover active tops.
- Audible / noticeable bass even at low volumes, without having to turn up the sub extremely

It is in my opinion definitely not in competition with 18zölligen low bass wonders!

The above requirements were met in the price range up to about 1600 EUR and for 15 "or 2x12" very well. Together with two 10 "QSC K10.2, the Sub is a very convincing foundation for filigree acoustic combos but also for punchy cover-rock bands (up to medium-sized pubs). As I said, he will not put a 18" sub in his pocket, but most of its direct competitors, then yes. With me he had finally prevailed against the slightly cheaper and provided with roles QSC K Sub. The RCF appeared more direct and deeper in direct comparison. He was ultimately more fun than the QSC. I am surprised that there is so little talk about this RCF Sub so far. I consider it an excellent solution for the above applications. The settings on the panel are a bit playful. Two buttons would have been more right for me.
