Pre/Pro with

Why are the Parsifals supposed to cross over so high? They are pretty full range speakers, afaik. Are you confusing the crossover to the bass modules with the crossover to a real sub?

In general, the crossover to the sub for most processors is much lower. You would also need an additional amp as the sub/lfe output of prepros is line level.

If you are looking to replace the passive crossover in the Parsifals with an electronic one, there are more appropriate units. For example, there's a nice deal on the nht X2 at http://home.comcast.net/~jhidley/ This would give you the frequency you need but you would still need the additional amp.

Frankly, I would leave the Parsifal's as is and add a single competent sub for the bottom end, if you need more grunt.

Kal & Bob,

My latest room is difficult and correction in the bass is a must for any speaker I've tried there, despite extensive room treatment. (I've had the P/Es in 5 other rooms over the last 10 years - this is a first.) More grunt isn't really the issue - it's less lumps, if you will. When placement of the P/Es is optimized for smooth bass in this room, it's not only still a mess, but the monitors end up too close to the listening position and - as a special bonus - I lose about a half octave of extention (relative to the best extention that I've achieved with the P/Es in previous rooms).

I've happily been using Ohm 100s and Velodyne SPLRs & an SMS-1, but I'd love to be able to switch back to the P/Es from time to time. Therefore, the idea was to cross-over from the monitors at Verity's recommended 150hz and eq the Verity bass modules. A pre-pro with room correction would allow both of these functions - if the x-over meets the description in my OP. My preferred amp is an ARC VT130se (balanced in only - no phase splitter), hence the XLR requirement.

If the NHT x-over allows XLR connectivity, it would work with the SVS/Audyssey bass only version or my SMS-1. However, the description of the x-over function in the C-1 provided by Mglenn is intriguing in that a really flexible high pass - coupled with the low pass in the SVS/Audyssey, or SMS-1, would allow me to rotate lots of different combos of speakers and subs/woofers at will.

The pice equation gets interesting, too.

1)NHT with my existing SMS at $200, or adding SVS/Audyssey at $700 = $900.

or

2)C-1 at $2K plus SVS = $2,700 with greater flexibility and potential to add multi-channel/video later.

or

3)balanced Audyssey equalizer at $5K (adds full range RC and multi-channel potential down the road with a pre/pro of my choice)

or

4) single ended audyssey eq at $2.5 K (adds full range RC and multi-channel as above, but I need to use a different power amp)

or

5) sell the Parsifal/Encores

Since I have a HT "movie" room with a recently added Audyssey enabled Integra AVR, the flexibility of #2 becomes a bit less appealing. I consume music (software) fairly voraciously and the idea of building a multi-channel library feels a bit daunting. However, knowing myself, I might end up doing just that at some point (particularly since the only reason I use my HT room is to watch "Lindsey Buckingham at Bass Hall", which is the only dvd - music or movie - I find sufficiently compelling to warrant multiple viewings. Otherwise this is my wife's territory). If I ever build a multi-channel music library, I'd definitely want to utilize my existing compliment of music hardware, rather than the movie room. That fact makes #2 more appealling.

All food for thought. Thanks all for the input.

#1: If the SMS EQs and passes up to 150Hz, this might work. I cannot recall if it does.

#2: I would not invest in an old non-HDMI avr or processor today.

#3: The Audyssey Balanced Processor will not do any bass management or crossovers. It will recommend them but not implement them.

#4: Same as above.

#5: Your problems, your move.

Take a look at the NeptuneEQ. Use only two FR channels now and have the others for the future. One box solution.

Take a look at the Theta Casablanca. The 2 channel stereo is better than anything I've ever had... and the programing on the Casablanca allows to do most anything you can imagine.
