This is a fantastic subwoofer and great value for money.
I bought this product primarily to incorporate into my existing hifi system to improve the sound quality of the bass when listening to vinyl.
I was generally happy with my setup as it was but had some limitations in terms of space so was continuing to use bookshelf speakers, as floorstanding ones were not an option for me.
I had read some good feedback for the OLi KH30s online in various forums and retail websites and decided to give it a go.
I was not disappointed. The sound of my records has been greatly enhanced with much more depth and clarity from the bass compared to before.
The setup was relatively easy too. I had no subwoofer output on my amplifier so took the L-R output signals from there to the subwoofer and then from the subwoofer to the bookshelf speakers. I used 14 AWG speaker cable throughout. The cable can be connected to the subwoofer using banana plug terminations or clamping on the bare wire. I went with the recommended guidance to place the subwoofer between the two bookshelf speakers although it is slightly off-centre due to other factors. The sound preferences are up to the individual listener but I have set the crossover at around 80 Hz with the subwoofer volume about 60% max and think it sounds incredible.
The unit looks great and was a perfect fit for one of the floor level compartments on my shelving unit. I have also connected a TV to the amplifier and the subwoofer also sounds perfect in that 2.1 setup. It comes with 4 screw-in cone-shaped mounting feet. The points on these feet are quite sharp and probably not suitable for wooden floors or surfaces. It did not come with spacers or washers that could prevent damage to wooden surfaces but I found it fairly easy to improvise a solution to this.
Overall, it is a really great product for the price and size. Highly recommended.
