Re: Hello from Arnhem, the Netherlands

Hi Marcel,
Generally I am not a fan of horn loaded speakers as I find that after extended listening to them I get tinnitus and this mainly from the HF horn driver in a multiway horn loaded speaker. I did not find this with the Monacor coaxial driver. I suspect this is down to the HF horn being ...

Re: A new development of my 'SWANSONG' speakers

Unfortunately no going back now Nick and it is what it is. I can however, line both sides of that brace with the wool underlay which should help with preventing any air bleed through the holes?

Re: A new development of my 'SWANSONG' speakers

No Reason Nick other then I needed to have these panels cut from the routed sheet of ply as there was not enough space to have them cut on the band saw schedule from the standard 8'x4' sheet. It cost no more to have those holes routed in the panels so I thought why not.
On the recommendation of ...

Re: GM70 PP

I agree with every thing Nick posted above.
You may give some consideration to caging those GM70 valves, especially if children come visiting.

Re: A new development of my 'SWANSONG' speakers

Slight change in the design of these new speakers.
After chatting with Chris661 and Scott over the weekend I have decided to drive these speakers fully active using the 3-way Hypex FusionAmp FA123 modules.
What with the success of the active bass setup on the big'uns it's been an itch I needed to ...

I have modified my CAD drawing to the MK3 variant the cabinet design and emailed a DXF copy with a cutting schedule list to by plywood supplier for a quotation for doing the ...

Re: A new development of my 'SWANSONG' speakers

Having emailed Scott a copy the MK1 and MK2 variants of the new speakers for comment, he had a couple of observations. He suggested that for optimum listening the HF driver should be at ear level when seated in the listening position at my home and to keep the bass drivers no higher then they are ...

Enjoy working on the speakers and I hope I get to hear them once up and running!
You'll certainly get an invite when they are finished. I'm sure Lynn will keep us well fed and watered in her usual way.

Re: A new development of my 'SWANSONG' speakers


Nice to see you are 'tinkering' again and looking forward to where you get with this new project :D


Andy, I'm afraid the 'tinkering' stops with these speakers. The 'swansong's' took a lot out of me and I'm not getting any younger so I had to promise Lynn these will be the last pair on pain of ...

Re: even more lateral fets


Painted heatsinks are not ideal.


Well the heatsinks on your P6 amps are black. I assumed these were either spray painted or powder coated? I seem to remember from my Physics 'O' level days that black painted radiators radiate heat better than white ones. But I confess to have little to no ...

Re: A new development of my 'SWANSONG' speakers

Fair point Nick.
However, that price I believe is from Soundimports which are based in the Netherlands. I cannot find a UK seller for the Purifi drivers. In which case wouldn't there be UK Import Tax and customs duties, plus currier clearance charges on that shipping price? Agreed though likely ...

Ed,
That chassis would look right shoddy if sprayed matt black.
