The Onken W I knew ran 416 woofers, IIRC. No sure how much of a change to the box and tuning you'd need to swap drivers. In any case, it's a crazy good bass box.

Ah, yes - I remember those well. I also remember moving them to the theater in 1987 for their first big show (Kiron). Heavy does not begin to describe it. Nantex plywood and sand filled walls will do that for you.

Thanks for the link.

Ok, HF144's are as good as ordered thanks to cheque from a small car crash - every cloud has a silver (toyata) lining

A few questions about crossovers and how to fit them to my system etc

1) If I feed the minidsp from a preamp for it to do the whole ADC/DSP/DAC thing, does a quality preamp like the B1 add anything?

2) How good is the minidsp at the ADC bit? I know I need it for my tuner, tape & vinyl to get played. Would an SRC2496 feeding a nanodigi with a 24/96 signal be a better combination? As a plus I get to pick my own DACs

I can't answer the second question, but we hooked up a couple low level preamps to the MiniDSP then a high quality preamp and could tell the difference night and day. I was surprised but it worked.

Tnx djn - good to know

I've heard the src2496 even makes upstream dacs sound better because of the uprezzed signal. I wonder about it's ADC feedin the nanodigi

FYI,
Ra7 rcommented in my thread, that he had the minidsp and did not have trouble with noise on his setup, but ultimately suggested passive over active EQ.

Doesnt the nanodigi mean that a 2way requires either 2 DACs or a multi input/output DAC

Yeah, with the nanodigi 2x8 you have to run 2 dacs for 2-way, 3 dacs for 3-way and 4 dacs for 4way. But I do get to choose what does my A/D conversion.

A passive crossover or PLLXO means I don't have to worry about digitising the analogue side of my system. However I'm not that interested in crossovers, just the outcome, so I doubt I'll be learning how to build a PLLXO or even a topflight passive for some time lazy? who, me?
