Raidho X-1

I may be of little help but I own the D1's. The D1's drop off the lows right at 50hz. I have a Rel B3 which adds a lot but also slows the overall sound. The D1's are very laid back and highly detailed without ever being bright boomy or in your face. The Rel B3 integrated fantastically with my Dynaudio C1 Signatures. Raidho's are a lot like electrostatic speakers without the size (very fast and detailed). The X1 is rated to down to 80hz.

My room is 26.5ft X 12ft with the speakers on the long wall.

I have a 110W Octave tube integrated driving them. No power problem for me.

I would consider a Dynaudio C1 as an option. They will go to about 36hz even though they are rated to 45hz. You'll get higher SPL's. You just won't get the clarity/imaging from the blacker background that the D1's have.

That said I have not heard the X1's (too new) but giving you what I can say about my D1's. You should hear a demo of either speaker before making a decision.

1: Small Raidho speakers can not play loud enough for such a large room.

That really depends how loud you need to go

2: If you use a crossover you will most likely kill the sound of the speakers

My Rel and most others have built in crossovers

3: It is very hard to get a seem less match with a mini monitor and subwoofer, made even harder by the speed and articulation of the Raidhos.

Have to agree regarding Raidho's. They are a very fast sounding speaker. I mentioned that in my previous post but for me it is acceptable. You should have no problem getting a sub to integrate seamlessly with a monitor unless the sub has some crazy crossover points and or the sub can't be moved around to get the phasing/timing right (don't want the sound from the sub leading or lagging the main speakers).

the speakers will be placed atop a long console table

Bad for Raidho. They need to be de-coupled to sound the best. There are 4 ball bearings on the top plate of the stand along with 4 more bearings in the feet for my D1's. Plus the stands themselves wobble (gasp) by design. If your serious about the X1's you really need to hear them first especially since they would be on top of a table.
