When I was choosing a centre speaker I did consider the Tempo and Maximo. But they aren't in the same league as the Integra Ovation/Hybrid Integra.
Since you will be installing those very nice Hybrids, it would be sensible to install a centre speaker of the same level of quality, or even better, of your Hybrids. The Maximo/Tempos would be fine for the rears. Or even keep them as L7.
