Crossovers, why so few options?

I use an NHT X-2 between an ARC LS-25 and an ARC VT 130SE with no discernable (to my ear) impact on the sound of the mains - other than rolling off the bass as intended. At all of $300 (sold direct, on a money back basis) it's an easy call to give it a shot.

BTW, I take the sub out signal from the x-2 and run it into an SMS-1, then on into a pair of Rythmik 12" subs. I do this because, in addition to the flexibility limitations of the SMS-1's high pass section that Kal noted above, I also found it (sometimes) audible (I think) and, therefore (always) distracting (Is that the x-over I'm hearing? no. yes. maybe.). Never happened with the x-2 in the chain.

The set-up took me some time and effort to get right, but it produces really excellent results in a very difficult room.

Good Luck

Does anyone here use an active crossover with a tube preamp? It seems like the input impedance on most active crossovers is pretty low as compared to tube/SS amps; has this been an issue for you in matching the preamp to the crossover?

Bob, I wonder if the NHT preserves the analog signal for the mains. If so, this is interesting. If it adds an additional stage of digital processing before output to mains, I would not be so pleased. Sub out doesn't matter so much (whether there is digital processing).

Rrolack,

My LS-25 is a tube pre-amp. No issues with the x-2.

The NHT x-2 operates entirely in the analog domain.
