[Crites CS-1.5 help needed]

Danzo and moray james thank you both for the welcome and the encouragement. I know I should ask Bob Crites about this but wanted some opinions on it being worth it over ref series. I suppose it's because this will be my first HT speaker set-up and is a lot of money for me, so I start doubting my choice. Thing is, I am really excited by the thought of building my own and just hope I can source the necessary parts.

[Crites CS-1.5 help needed]

I'm new to the forum (and new to Hi-Fi/HT) but have been reading for quite a while, since I started looking for speakers for a HT - this is not a dedicated room but just my living room.

After deciding on RF62/RF82, RC62 and RB52 speakers I came across Bob Crites' Cornscalas and thought WOW! My room is not really big enough for these so I thought that 3 x CS-1.5's and 2 CS-1's would be good (am I right, would it be worth building these over buying the reference line?).

My problem is sourcing parts as I'm in the UK and ordering from the US will cost a fortune in customs charges etc. I was hoping to buy only the crossovers from the US. I should be able to get the Selenium D220Ti (still waiting to hear from seller if these are 8 or 16 Ohm) but not the Selenium HM25-25 so would likely have to get this from US also.

So, a few questions:

1 - Would the CS-1.5/CS-1's be worth the effort over ref series?

2 - Is there a difference between using the 8 or 16 Ohm D220Ti drivers?

3 - What would I need to look for in a woofer that I could use with the CS1 crossover from Bob Crites?
