Thanks for your reply and insight above. In response - for example with my PM90 which I figure is relatively standard in using the FB464 passive crossover designed for the DCX464 : 1 amp channel supplies 2 poles +/- to the NL4 port, and then to the HB464 crossover board. On the XO board it has...

Yes, it is easing to know that that is the right way of doing things - this is my first build so I thought all had to be matched. Thanks for the tip and reassurance on amp choices. It is right that the subs need ~2500w each if there are 1250 watt rated ? This is where things get weird for me...

Yes apologies that was a typo - such a great and informative answer thanks David. Was planning on building 4 subs running 18TBX100 rated at 1250 RMS / 2400 max - already have the 18TBX's. Perhaps I could power with a cheaper sub amp with simple crossover filters and power the tops with a...

Hey guys, haven't posted in a while but have some progress pics to share when I get them off my phone. Proud to say we've finished building our own pair of PM90's - but I have an important question to ask regarding amplification and worrying that I have royally messed up here. Basically, I have...

Hey all - can anyone advise if the DCX464 will fit with RCF MB12N351's ? Does it require a spacer on the front (i.e. where the HF950 joins in order to pull it forward away from 12's internally). The RCF MB351's have +5mm on the outer diameter but 280 (vs. 283mm) on the internal mounting diameter...

Hey everyone + Peter, this thread is really inspiring and I've learnt a lot. Thanks so much Peter for this incredible project and build. I am intending to build 2x PM90's in the next month and have read through all 39 pages of this thread. Currently intending on the BMS4954HE + B+C 12NDL76's...
