I'm using a tripath pre-amp at the moment, but my colleague thinks I will be much better off with his Yamaha DSP-A2?

If i had those i would either add a sealed sub for full range use or use them as mid/high in a multway speaker system.yes , probably the yamaha will make them sound better.

Yeah, so it would be a good idea if I was adding more speakers in the future I guess...

Here's something to motivate your inspiration.

On a side note, I was talking to a colleague and he said he's willing to part with a Yamaha DSP-A2 at a very favourable price and I was thinking would this make a better accompaniment to these speakers?
Hi Martin,
Glad to help.
I've had a friend in the UK who used this Yam, very good from what I remember. Some care with the volume control would be needed as its quite powerful for the CHR's.
Cheers
Mark.

Hi Mark,

He says it's in quite good nick so I'll probably take him up on the offer!

Anyway, I did some basic calculations and it seems to indicate that the total internal volume of the speakers, without the internal parts and assuming a perfect sphere, is 9.6l. If I minus all the internal parts (and taking a guess at the drivers too) then it comes out to be around 8.8l... If I were to add a port, would I look for an equivalent normal shaped BR box and what the port size for that would be?

Hi Martin,
If you can get the Yam for a nice price and its in good condition, could be a good buy. Talking of amps, I'm hunting for an all-Japan Luxman 503S this during the coming week in Tokyo - see pic. I've gotta a bit of the "love thing" for vintage Japanese Moffys.

Looking at the bowls, I'd think a 1" (25-mm) diameter port X 50-mm long, Fb around 54Hz, F3 around 49Hz, looks reasonable. This should get you started. I guess you'll try to squeeze them in the lower real bowl? You might want to try 60-mm long to kick off and trim back depending on room placement, your listening preference etc.

Other members might like to try on their software, offer some additional variations on my calcs.

Cheers
Mark.

This Lux gained a reputation for smoooooth, possibly due to it's lower power output. I'll use with my home Pensil 7's while I upgrade the 300b's transformers.

My take on the IKEA speaker:
The missile nose cone (true!) in the back is the (sub)woofer. Just finished it, haven't had a chance to do more than casual listening though.
