Vadnerseen 5A crossover outside

The crossovers are battery powered (9 volt) and connect to your amp and the cables connect to the crossover so you really don't need extra cables. By the way I would take Bo with a goatee and sideburns.

A bit of additional info to add to the points already made:

1. The Vandy Model 5 crossover housings (one for each channel) are attractively made of stainless steel (unlike the plastic crossover housing supplied with the Vandy 2Wq subwoofer), and are unobtrusive since they are located between the preamp and the power amp (the preamp outputs connect to each crossover unit, and the built-in crossover cables then plugs into the power amp's inputs).

2. As "Rec" notes, each crossover box contains a 9-volt battery which keeps the capacitors charged (Richard Vandersteen states that the batteries only need to be replaced about 7 years). Each crossover box contains audiophile-quality capacitors and resistors, and all electrical connections are made with silver solder.

Thanks all, but why do other speakers do not have thois issue?

You are missing the point completely - the crossovers are a very ELEGANT solution to perfectly blending the subwoofer to the main speaker - NO ONE does this better than Vandersteen.

When properly setup (not hard to do) you cannot tell there is a powered subwoofer - it blends seamlessly with the speaker - becomes one with the speaker. All because of that little, unobtrusive crossover that you place behind your amps.

As for the electrical requirements, that subwoofer amplifier. in combination with that ingenious crossover, unloads your main amplifier so that it can make the midrange and treble magic.

Enough said. Go listen to the 5s.
