Hi Gents I've been looking around for quite a while for a speaker that would allow me to keep my beloved Audio Innovations 500 valve amp that I bought to celebrate my 21st birthday 23 years ago. It still works very well but it's less than an ideal match for my original Acoustic Energy AE1's now i have bigger room. I'd like a bit more bass for movies, and the ability to play some organ music or a realy sonorous chello piece once in a while would put a smile on mine and my Dads face! I've been working as a full time draughtsmen for about 6 years and really miss the fun of making stuff. Satifying a number of needs in one go the little big horn kit fits the bill, Not cheap but the reviews on the originals are pretty awesome so the deposits been paid! I've built plenty of precision stuff so no real worries getting the project constructed. Being in kit form I can choose and order the parts as the money arrives. So the main challenges are: Getting it to sound at least as good as an original pair. Getting it to look as good. I've had a long e-mail discussion with Andrew and lots of advice has been received - thanks. The critical parts appear to be the size of the chamber behind the main driver - any speaker requiring more space than the Lowther DX3' and 4's supplied in the original could stuff things up nicely. I'm inclined to go for broke on the horn driver and buy some Lowthers. The next part is the integration of the subwoofer output with the horn. Andrew has reccomended the Oaudio 300watt bash amp as being good value. I've priced it up and it's only fractionally dearer than Dayton Audio 250watt plate. The Oaudio includes full phase adjustment 0-180degrees rahter than just a phase reversal switch. Sub drivers is a big question - i'd like to go low enough to put a bit of guts into Bach's Toccata and Fugue (or some Rammstein) but i definitely want to stay away from the boyracer stuff - music not thump please. The cabinet for the drivers works out at about 84 litres. The original Carfrae design had a peerless driver and a port in each base unit on one side. This enabled the base units to be swapped under the horns from left to right fireing into the centre or out to the sides of a room. I quite like the idea of a passive radiator design but wonder how the directionality of the bass would be affected with a driver one side and the radiator back to back on the other side would be. Your thoughts and advice on this and cone type for music would be appreciated - paper, cloth, polypropylene, aluminium? I've never had deep bass from a pair of speakers - so i've never had the chance to gain much experience. Last but not least how to finish MDF given the size of these things spraying them in or out of doors is out of the question. I'm thinking about someone witn a spray booth. There's a few horror stories about DIY MDF cabinets cracking up around the seams long after painting due to weather, home heating watever. It would be relatively easy to set up a router and put a tiny bevel on the edge of each section of MDF before i start gluing things together this might lessen the visual impact of any cracking whilst putting a subtle set of stripes on the horn. Your thoughts please. Ta Steve
