I use this sub for almost 2 years and really for the price it's great.
Good finish, sturdy gate hyper, like the wood used for the sub.
You type in the real pro stuff.
The value for money is very good, the sub are their job admirably, no humming or excessive vibration (Hk and Yorkville for help to flee ...), we feel we have a case 18.
I turn my head with 2 DAS DS115 and the result is great.
Not a criticism of foam behind the protective grill apart from that nothing else was wrong.
Excellent choice with the heads DAS DS115, the sound is clean, consistent and harmonious.
Yes I will sign a new order for this kit.
