To make a successfull loudspeaker in this overcrowded market, I think you need to be very passionate or even obsessed with loudspeaker design. You also need good ears. Adam had neither of these things, and the only reason he did it was to run a business to support his family (not that I blame him for trying). I helped out with some measurements but I was still learning and I didn't have much say in what went on.
The original prototype was easily the worst speaker i've ever heard in my life. Even Tracy Chapman sounded like she was singing in a small bathroom (Tracy Chapman is one of those recordings that sounds good on anything). The woofer was the SB Acoustics SB15NRXC30-8, but because of breakup it needed to be crossed over to a tweeter quite low (around 2khz IIRC) the Isodynamic planer tweeter tweeter didn't like being crossed any lower than about 4khz, so I suggested using a different woofer with a smooth roll-off (I think he went with Seas in the end). I gave up by this point and we parted ways (not that I was a partner or anything). I heard the final version at a show but it was still bad.
It's quite frustrating to know that I think I could now make the original combination of drivers work by slitting the cone and filling the joints as Joe Akroyd did in the last speakers he made (Scanspeak also sell Slit coned speakers). I've done it with other drivers and it works quite well at smoothing the frequency response and lowering distortion with hard coned paper drivers. I'm also far better at crossover design and modelling port tuning etc - Oh well
If there are any headhunters out there looking for obsessed loudspeaker designers, PM me (I'm confident I can prove myself, which is unusual for me because i'm not normally confident in anything I do).
