Those ebay multi-cell are odd. Some of the cell dividers where they join are thin (good) some or not. I wonder what that's about?

Pano,
Those multi-cell horns are hand made and I would assume that has a lot to do with the consistency from one unit to another. I doubt that the builders are using fixtures to assemble these units. I also doubt that a difference in the spacing between cells would have much affect and would be at very high frequencies at least.

I'm not sure that spacing differences would hurt much, but the thick dividers might. You don't want ever more reflections in there than you'll already have.

That said, those faults might be mitigated by the non-resonant, wooden structure of the horn itself. Would love to hear one and compare it to the Altec.

From what I can see, on the 15 cell version the middle 9 are very thin walled. Its only the outside banks of vertical 3 cells that have the thicker walls and they seem to have something to do with the angle of those widest cells - they are thicker on the inside wall of the cell angling down to thin on the outside walls.

I assume (uh oh) that the outer banks of cells are not as important as the central 9...........shoot away fellas

Its 'only' 200 miles there, 200 back - I feel a road trip coming on! That means I need a car however insurance assessor comes today. Hope he's on time. I want to see Skyfall before the madding crowds can get to the cinema.

Hey Sippy. They've been knocking about for a while there. The horns aren't bad but if the drivers have original diaphragms they'll be ancient and need replacing. GPA have them for about 60 a piece but you need a conversion thingamy doodad done . They are just too old to be left as is I think. more than likely way off original spec

I'd take the horns and get new GPA 902-8's for 130, but I doubt he'd split 'em

Lager?

Harveys since 1790?

EVERY advert before the film was shamelessly Bond linked lager, aftershave, cars, sony phones, tablets & laptops, video games, clothing......it rather cheapened the franchise & film. Also someone has missed a trick there - BOND SPEAKERS!!! (they'll flirt with you, put you at ease, buy you a fancy drink, and then some lunatic with a bowler hat will kill you)

TBH its no Casino Royale.....

This is a wait for the DVD film I think. Its more lost in the desert than Quantum of Solace was and the villain was about as frightening as an undercooked chicken leg

engineer looked at the car. Just the door needs replacing. I'll have to see how much the give me. It'll need a new door (easy) a new MOT (only passed in August) and a VOSA test to make sure its not a cut'n'shut

Lets see what the offer
