Oh yeah...!!!
Nice one Chris mate, you'll be pleasantly rewarded!
Funny one that, I've previously owned exactly those other speakers as well. Including Maggie's (many many Maggie's), Quads, Apogee's and the CLSIIz's and SL3's.
The CLX's are on another level, there's no comparison at this level. These are very high performance speakers and will reveal anything and everything you drive them with, plus all of your components in the system.
Apart from the CLX's, just be prepared to spend a bit more on other areas of your system because these full range stats will highlight every tiny flaw or shall I say compromise.
There's no way to achieve 100% perfection but if you've achieved at least 95% or a high 98% of blissful playback quality, just sit back and enjoy those finest tunes!
Note: with the subs, there's a specific cross-over point you want to trial, especially with the CLX's, your subs and your room set-up. A very wise man told me, that since the CLX's are around 55 to 56Hz in LF, try to cross over the sub at least 10Hz below that level, not higher. If crossed over at a higher level, both the slopes of LF from the CLX's and sub will overlap, causing the sub to be heard.
The idea is to make your subs disappear. Anyway, I'm thinking that you already know this. I did try various subs (three different kinds) and ended up with just one ML BF210. Matched with the ARC software and fine tuning on custom controls that the BF series has, the sub simply disappears! One was more than adequate for my room set-up. Two would be nice but I didn't require it.
Just for fun though, first try the CLX's without the subs. Play anything with bass lines and you'll be truly amazed at the speed and agility of the CLX's LF detail. It's all to do with the double bass panels, having a structure comprising of triple stators and dual mylars. The speed and linearity at which this bass frequency moves is truly supreme! There's simply no sub on earth that can match that LF speed and detail of the CLX's bass panels.
In fact, many have Criticised the bass on the CLX's and have called them, "bass less." They're so far wrong... they have no clue. They're used to box / cabinet type of bass colorations. The CLX's don't have a box, simple as that!
However, there are certain LF notes, such as organ, synthesised bass and so on, that is sometimes missed out on the CLX's. Apart from that, if it's on the recording to begin with then the CLX's will reproduce it. Only on those very low notes, 30Hz and below... the CLX's won't capture it. You can certainly feel it but not quite as full range dynamic drivers. This is where subs help indeed! But as I said, provided these LF's are on the recording... otherwise using subs to me is actually adding artificial enhancements, which aren't on the recording. Just my 50cts worth.
Cheers to the CLX Art's!
That deserves a mighty WOOF!
BTW, what colour and finish did you get?
