@MartinH ah sorry mate I didn't see you post, I think I was typing my response! Exactly the info I need though. I will cycle to maplins tomorrow and purchase some resistors then.

@keith that xtz room analyser is £150 though. I wonder if I can get something to work with a cheap mic.

Ok, I'm back. Strop over
If you have a tablet, you can buy a decent RTA software for a few quid. I use Pocket RTA HD for iPad. The iPad built-in mic is OK for rough measurements, but a proper calibrated USB mic is best. I have a Samson Meteor mic (£60) which is one of the only ones to work with the iPad and not need an external PSU/Hub. I also got some mp3 test tones from the internet.
The 5, 7 or 10W wirewound ones are the ones to buy - just grab a selection (2 of each) and have a play. I think I settled on 2.7 ohms myself.
Will, yes I thought that the resistors would go in the +Ve speaker side, but inspection of my crossover circuit showed that they needed to go in the 0V see circuit below. I guess it depends upon your speakers.
Cheers,

Hi Martin, I have to confess that I did mine with the help of a 'grown up', in this case 'Wilmslow Audio' who are close by and very helpful...Originally Posted by Martinh

I'd bought a couple of pairs of used Mission 780SE's (bi-wired) with knackered bass drivers, and their advice was to use some Monacor drivers as replacements, however on closer inspection the originals were rated at 6 ohms, the replacements at 8, hence a rather bright sound (i.e. the tweeters were 6 too)...
£2.00 & about 10 mins later all was sorted with these little fellows, and in the case of the Missions, at the +ve terminal seems to work nicely...
Cheers, Will

Looks like there are various android apps that do spectral analysis so I'm going to try them.

My one concern would be the bandwidth of the mic on an android phone, from what I've read they only cover approx 300hz to 3khz, as their designed for speech, perhaps on a larger tablet with a mic in....
