The Arendal Towers will, in my judgment, perform their best in a comfortably large but not huge room. In a more open space, common in many homes today, the bass might come across as a little lighter than you might expect from eight serious woofers (four per side) working together. (If they do, just turn down the HF and midrange controls and turn up the volume to compensate.) Even in my large room, the bottom end was consistently clean and well-controlled. The Arendals’ rich, realistic detailing across the board was possibly the best I’ve experienced in my listening room, though also the largest, heaviest, and most expensive. If the size and the price of the Arendal Sound 1528 Towers don’t faze you, they’re well worth serious consideration

As I said, dynamics are where horns excel. The Trio15 Horns lived up to that expectation. From ppp to fff, the Trio15 Horns handled it all with aplomb. How many times did my wife and I sit down to listen at what we thought was a reasonable volume only to end up with a symphony orchestra at full tilt in our living room! Of course all this was at such a low distortion that we didn’t even realize how loud it was until we tried to talk to each other. My favorite demonstration of the incredible dynamics was not large-scale orchestra music, but a solo instrumentalist. The recent Michael Hedges compilation Beyond Boundaries, has several songs of him playing the harp guitar. These close-mic’ed recordings demonstrate the forcefulness of Hedges’ playing. No matter how many times I listened to these songs through the Trio15 Horns, I literately jumped every time Hedges banged out the bass line. Amazing!
