Hi folks

I came across this board when following a thread on the Danville Signal DSP devices and thought it looked like a good place to hang out.

I've been around the audio business for a long time - 1970 or so - and worked in development engineering for a good proportion of my career - I was Technical Director at Celestion for a while, and also at Tannoy. I'm long retired now but like to keep a watching brief on what's happening.

My current project is a total re-engineering of my Celestion 6000 system into a modern 3-way active setup [hence my interest in Danville signal]. I've already acknowledge that the good ideas in that system have been picked up and run with so that it lags a long way from modern standards, so there'll be beryllium tweeters and completely rebuilt bass/mids in the Aerolam cabinets of my SL700s and the dipole bass system will be completely rebuilt. I want access to the Danville Signals processing equipment to generate crossovers and drive unit conditioning profiles, plus various time delays to integrate the system into one apparent source and to shape and steer the output of the dipole sub bass system.

All in all this looked like a good place to get help and perhaps give a little back - I've a little bit of background - I did my first three way active, DSP controlled loudspeaker system in 1997 and exhibited it at the Heathrow HiFi show that year - all I could find back then was the XTA DP226 because that was pretty much the only product on the market and its limited muscle made things difficult to get right - I look at some of the modern kit like DEQX and positively drool

Anyway: this is me and it's good to meet you.

Welcome to DCAudioDIY here in the Colonies! There is a lot of knowledge to be gained and a lot of opinions -- since you live in the "home" of audio and the greatest designer to have ever lived (Peter Walker) I hope you will not be disappointed.

Cheers and a pint of your favorite brew!

I'd have to come stateside for that since it's Anchor Steam.

I understand why you plump for Peter Walker but I spent a lot of my early days in the industry talking with and learning from Stanley Kelly so I'm biased towards him for that accolade - In 1973 he showed me a beryllium HF unit he kept in a drawer at his place in Margate having made it in the early 50's when beryllium was unobtanium - and he invented low foam detergent!!!

Welcome Ed. I'm looking forward to you joining in on the fun. I hope you make to some of our get togethers.

That would be nice - haven't been to the other side of the pond since 2001.

Ed Form

On the other side of the pond have you kept up on these speakers?

Welcome Ed. Seems like you've had a fulfilling and amazing career. Congratulations.

Hope we can be a sounding board and resource for you. You have lots to contribute to us. Friendship, first and foremost.

Yes, I'm very familiar with the work. He's a clever man, Don Keele.

That sounds good - audio is a nice world to live in.

During my evil past I had a pair of Kelly Ribbons. No one has designed an improvement on that speaker to this day. I think Dick Sequerra came closest.
