To me, and it is my opinion only, the scarcity of Rolls products in the UK, price and the fact that it needs an external PSU, would rule this out for me , especially as it is many times more expensive. 

I got mine from Parts Express in the US. Any little 12V PSU will do. From memory around 50 GBP.

It Sounds like I should probably pick up a used crossover ...  perhaps you could point me in the direction of something suitable , ideally smaller rather than bigger ....  I really was looking to avoid ending up hauling a rack around  with the next pickup being "proper"  Active Tops 
 

Yeah I think planning your next System is a great idea. It is much better to know where you are going as it informs your purchases rather than rushing into cheap fixes that only last a few weeks before needing the next bodge. I've spent a lot of money early on making do when a more measured approach would have saved a bit of money in the long run. I learned loads by making mistakes though  That's why I applaud your current solution. It lets you get on with playing music whilst you plan something better. I used to have a Stagepas 300 and that and the 500 aren't really good for a band, they just struggle for volume. the 400/600 were much better. They are good for monitors though as the sound is pretty good with no nasties to cause feedback issues. You don't need them to go so loud as monitors.

 

If you do go for a crossover I wouldn't worry too much about the brand, Behringer are the most widely available https://www.thomann.co.uk/behringer_cx2310_v2.htm

 but there are lots of other OEM products that are essentially similar. Used ones are curently £35-50 on Marketplace but at £77 a new one might be worthwhile depending upon how tight funds are. You'll get £35-50 if you upgrade so it'll cost you £30ish for indefinite 'hire'.

 

If you want small then there is this. It's programmable and 24db/octave filters are available on all four channels. You've also got limiting so you could program in some protection for your tops. Harder to sell on when you've finished with it though as it is a more techie solution

Now who would go and do that ay ...

Cough ....  this is exactly what i was looking for as i want to avoid Rack gear and  it looks simply enough conceptually would you look at that its fallen off ebay ... 

Now ... I guess i have to decide what  at frequency im crossing .... perhaps because its running to a dedicated  bass amp rather than a sub it should shoot a little higher to 100 /120 rather than 80 ?

Nice one! 

 

Well given that one of the reasons for having a sub is to take load off the tops, be interested if there's any reason not to cross over at say 150Hz, and you can get some bass as well as your kick handled by the combo?

 

Wished I'd used this crossover set up when I had a MB Alain Caron, which has excellent speaker excursion for a bass combo, with my RCF 310A tops. And ideally combined with the IEMs my crew are using today to avoid needing monitors. 

 

Tbf probably would have beem no better than the pair of RCF 932As which we're using currently and overall a comparable outlay.
