 Hello to all . I am a new member long time lurker. Like the title say,s my bps 210 has sh-t the bed and I am looking to replace it .My system consist of CJ MF 200 running highs Bryston 4b running lowes through a CJ pv12 xo1 crossover into mg 3.5's.My system is mainly for audio and listen to jazz and steely dan pink Floyd kinda stuff. I'm thinking about using the mirage LFX 1 crossover and getting an external amp and building two passive subwoofers. What do you think I should use for a amp ? What do you think of parts express amps and drivers? If money was no object I would really like to get a Bryston 10 b crossover and another Bryston 4b to run the subs but I can't afford to do that now . I would rather spend the money on really good drivers and build a really nice mahogany box. Any help or opinions would be greatly appreacited.

 My go to suggestion for subs

Sealed bipolar sub with very good drivers.

 For crossovers the First Watt B4 is probably the best choice in performance and flexibility. The Marchand XM44 is also a very good choice and Marchand can build you whatever crossover configuration you need for any number of channels up to 4 per side, 8 per box.

For starters just use the low pass filter on the active subwoofer box. If you need to high pass the bass panels you can use a capacitor in series going into your 4B bass amp.

 Satie thank you for reply. I realy like the idea of bi polar sub .I also considered servo type. The bps210 worked very well with my system. The only thing I don't get is if I do the Dayton rs1202k can I still use the Mirage lfx 1 ? Do I have to go to first watt b4 right away or can I ad it latter?

 You can use either of the items' various filters together in any combo of low pass and high pass filters. The built in filter in the powered sub is the one I would use and then use the best sounding high pass filter I can for the mains. I would use a DIY line level high pass in 1st order (a single high quality cap) and try to match the sub low pass with it.
I have on hand a Rane LR4 commercial crossover and an Ashly XR77/18 Butterworth 3rd order unit - The old ashly is very good but dates to the 80s so you would need to put in $2-300 in recapping and cleanup to bring it to long term high reliability operation.

 Satie thanks again for reply. I'm kinda lost now. If I go with the Ashley {wich I heard works well with maggies ] would you be able to upgrade it? Doing electronic work is way above my pay grade. If you don't want to do you know where I can have it done. Is it stero or mono? Will I still have to use the xo1?I'm sold on the Dayton rs 1202k.The only thing I would like the crossover to have the ability to ad a another Dayton in the future.

 I think you have many options for a more fixed freq device like a Marchand or a discrete freq and slope switching one like the B4 that would cover your needs. I needed the Ashly and Rane because I am constantly experimenting so I wanted a continuously variable one..

The B4 is a 2 way crossover and you can daisy chain them if you need a 3 way for a sub and biamping the 3.5.

For your current issue of a sub XO, the built in low pass should serve you well, you can start with the internal crossover on the subwoofer and once you have a favored frequency then move on to select the high pass configuration and frequency you want.

For the final high pass to the bass panels I still think you should just use an in line capacitor at line level. That is something I can do, it is really simple. You could probably do it easily enough. Many of us have built them.

You probably don't need something like the Ashly. Besides, I don't know if I can do soldering work yet. Still getting used to the new glasses after the cataract operations, have not done significant soldering in a couple of years. Most independent pro audio repair shops can handle the revival of the Ashly.. I am sure you have one close enough to you.

 Satie thanks again for reply. Do you think I can get by with my XO-1 crossover with the mirage lfx-1 for know?

 You can use the IFX-1 for the sub and to high pass the speakers, then feed the speaker output to the XO-1 and use it as you have before. Likely to sound better than the internal crossover inside the subwoofer amp.

 If I use Lfx1 andXO1 will It also help sound quality to go for a amp like a Bryston 4 b and make my own passive dipole sub.I am not looking for 1000 w of ground pounding bass just to fill in lower rang accurately.

 The requirements that let you fill in the bottom octave at all: i..e large diaphragm, powerful drive etc, also provide the capacity to play louder. If you go to an OB you will have a 1kw servo amp with eq driving the woofers, OB subs need EQ. If you already have a powerful amp at hand then just order the kit components without the plate amp and use the amp you have and your Mirage XO. You can call up PE and ask about getting the kit discount without the plate amp.
