I thought this deserved a new thread, rather than adding to the Proprius and high efficency thread.
Some pics of the kit and early assembly.

One set of panels and one dry assembled speaker


The back


The front



Stuffing for the inner taper section



Stuffing wrapped in adhesive scrim tape to hold it in shape



Stuffing in place



Tape allows drawing right into point of taper



Cabs have now been glued together, more pics later.

Just listen, if it sounds good to you, enjoy it.

I am also interested in speaker construction Ian. I would like to use my AKG K1000 to help me build a speaker system with the same response accuracy. Headphones just don't give a large stereo field like speakers can.

Thanks Bob,
I've spent most of the last 3 days sanding, applying sealer, more sanding and more sanding (120, 150, 180, 240 and 320 grade). A great accompaniment to listening to Test Match Special. Now I shall let the dust settle before waxing and polishing and watch the closing stages of the Cricket.
Hi Ash,
Finding (and making) a speaker that has similar attributes to your headphones will be very difficult. speakers are a totally different aural experience. Whilst the driver or drivers in a speaker could achieve a similar response, the interaction with it's surroundings will have a significant impact, unless you create an anechoic listening room.
I think it is this interaction that gives speakers such a different sound/feeling combined with the whole body sensation of sound. Such things as the strike of stick on drum are felt as well as heard, something that headphones will never achieve.

Just listen, if it sounds good to you, enjoy it.

I have come to realize that in order to experience the audio recording even more than from a K1000, the performance has to interact with the whole body. Nothing sat on the head is going to achieve that, regardless of design so the natural progression will be to return to speakers. I have a lot to learn yet though but I'm not going to give up on them like I said I would. This is why I kept the Proprius. Wink I think I'll research some high fidelity drivers, buy them loose and build various enclosures using the Meccano that I have in the loft.

Ash, A few names to Google for starters on Loudspeaker design:
Martin J King, Vance Dickason, Scott Lindgren and Dave Dlugos. Closer to home a phone call to Ivan at IPL would be informative and could get you started at a reasonable budget. Oak-Audio.co.uk supply the MarkAudio drivers I'm using as well as fully built speakers.
Hope this helps, although in your internet travels I'm sure you will probably have come across some of these.
Just listen, if it sounds good to you, enjoy it.
