Hola,
Como me fue imposible conseguir un central Odyssey Nemesis, decidi irme por el camino del DIY. Despues de ver opciones, me traje el kit Usher 701 diseñado por el Dr. Joseph D'Appolito y que utiliza un woofer 8945A y un tweeter de seda 9930:

El Kit viene asi:

The Usher 701 is a classic two-way bookshelf system possessing accuracy, detail, and a transparency that must be heard to be believed! The bass response is articulate and effortless, the midrange is balanced and extremely accurate, and the high frequencies are smooth yet detailed. This speaker kit was created for Dayton Audio by world-renowned audio authority Dr. Joseph D'Appolito. Dr. D'Appolito's engineering prowess, in combination with the Usher 9930 1-1/8" tweeter and 8945A 7" woofer, has produced what we feel is one of the most exciting speaker kits available. Joe D'Appolito designed a speaker that is smooth and non-fatiguing, with accuracy rivaling that of many commercial studio monitors. Proven-quality components are used in the superbly optimized pre-assembled crossover. The speaker's on-axis frequency response is flat within ± 1.7 dB from 100-20,000 Hz. Dr. D'Appolito summed up the Usher 701 kit perfectly when he said, "I'm quite satisfied with the results!", and you will be too! This speaker is reasonably priced and easy to assemble, making it perfect for any audiophile—novice or experienced. Available in choice of cabinet finishes (gloss black, cherry, maple), and in straight- or arc-sided versions. Sold individually. Specifications: *Impedance: 8 ohms *Frequency response: 41 - 20,000 Hz *SPL: 86.5 dB 2.83V/1m *Power Handling: 80 watts RMS *Cabinet dimensions: 17" H x 10" W x 12.5" D.

De momento voy a utilizarlo con el XO que viene en el kit, pero ya tengo localizadas algunas modificaciones que supuestamente afinan aun mas el diseño del Dr. D'Appolito. Originalmente pensaba comprar unicamente las partes y fabricar la caja con sobrantes de madera pero cuando vi el costo de la caja terminada en negro piano al alto brillo no dude un segundo en ordenar todo el conjunto.
