In some cases, however, researchers are looking at how printing microscopic objects can lead to macroscopic changes in physical properties. Nanoprinting technology is most often dedicated to printing specialty nano-scale biomedical and electronic devices, usually for research purposes.

It is in fact one of the most useful speakers in the class, and one of the few that can give you a real feeling of being at a concert at home in your own living room.Continuing in our series on metamaterials, we will be exploring nano 3D printing. But it is when you turn up the volume that you understand why the HDI 3800 is so good. They still tower well in the room, but can be delivered in three finishes with fine furniture quality, and look good as eye-catchers in a large living room. A hard-hitting and powerful bass, with enormous dynamics and the ability to play both crazy loud and cleanly at the same time.

The JBL Synthesis HDI 3800 is the decor-friendly version of JBL’s professional speakers, and offers very much of the same features. Dynaudio Evoke 50 and the aforementioned Bowers & Wilkins 702 S2 Signature, are two other options, which are not as hard-hitting, but slimmer options that are easier to place. The more elaborate cabinets on a pair of Sonus faber Sonetto V, will probably appeal to many, and here the sound is even better balanced with more warmth and glow. It may have even a little more energy in the bass, but is not as refined and balanced as the JBL speaker, still definitely a fantastic fun speaker that is worth considering. The closest you get to finding a direct competitor to the HDI 3800 is the Klipsch RF-7 III, which is a rugged speaker with an enormous sound pressure – and two 25 cm woofers that you feel on the body. A switch to the far more potent H590, solved the problem. The amplifier of 60 W, played superbly to a certain point, after which it was not so easy to control the six woofers with the same tight grip. Even the powerful Hegel H120 had problems with the control when it was pressed on the 3800. Just forget the data, they are admittedly relatively sensitive at 92 dB, but that does not mean that the random old 30 W NAD amplifier from the 80’s is a good match. But at the same time they manage to hold the sound image together, that is, if you have chosen the right amplifier. Inside, there are vertical braces especially where the woofers are located, which absorb the energy from 3 x 8 inches at 100 dB+ sound pressure.įor these beasts play loud. It gives a stiffer outer shell, than if the cabinet surfaces were just that, flat. JBL says that is precisely why they have chosen curved cabinet sides.
This 2.5-way speaker would fall apart like a cardboard box when you turn up the volume, had it not been strengthend and braced well enough. For those who like surround and cinema sound, there is also a 12-inch, 1000 W powerful subwoofer and a center speaker in same series.īlack, glossy paint with hardened top coat as on a car paint. There is an HDI 3600 also for those who do not have room for the 3800 model, and a relatively compact tripod model called HDI 1600. The JBL Synthesis HDI 3800 is the flagship of the HDI series, which is the more decor-friendly variant of the huge studio speakers from JBL. But they are easier to place than you think, despite the fact that the bass reflex ports are located at the back, and they can easily be matched with a 60-watt amplifier.
With a height of 110 cm, they dominate the room visibly. In other words, they are not for the faint of heart, because even though the speakers like to play at moderate volumes, it is only when you crank up the volume that the fun begins. Six eight-inch woofers with rigid aluminium diaphragms, feel like having a six-cylinder engine bolted to the chest, when playing loud.
Still, the slimmer speakers really pack a bite, that you will notice physically. They are large, but much smaller than the huge Synthesis speakers we tested earlier this year.
