The selection of high-grade materials in combination with accurate acoustics craftsmanship makes the MERO speakers superior in their class. The medium sized MERO5 consists of a 5” aluminum cone woofer and complementary 1” dome tweeter that are smoothly matched and optimized using a high-quality crossover network. An acoustically optimized waveguide matches the dispersion of woofer and tweeter, while a phaseplug reduces diffraction and enhances off-axis high frequency response. All these details share their part to its pure sound. An elegant look with minimal visual impact is created by the slim grill with very thin border, while great ease and installers convenience is guaranteed using the quick-fix mechanism with Gold-CON connectivities. The grill is held in place using neodymium magnets, providing a quick and stable assembly. Installation can be done in both vertically and horizontally, while the rotatable tweeter allows optimal orientation positioning.

The CELO and MERO series speakers are designed with very light membranes to work in free air without closed enclosure on the back. The smaller the enclosure gets, the more the low frequency response will degrade.
Our recommended application is indeed to use the CELO or MERO series speakers in an open ceiling or surface with a very large volume on the back. We know that is not always possible, however for small volumes there are other options recommended (e.g. CALI series with a closed back can).
To guarantee a decent and acceptable acoustic performance for a speaker such as CELO series, experimental testings have learned us that a volume of ~ 15 Liters turns out to be OK and acceptable. But the larger the space, the better the low frequency response will turn out. So any additional liter is welcomed.
