    I dont know who "balloon boy" is, but I would rate Volt bass drivers over all others.
    Even their trade prices are scary, but if you want a hand made driver built to the highest tolerances, there is nowhere better to spend your money.

    You do have to accept you will not get the best out of them with a 5W SET amp though.

    Marco.
    In fairness, he spent years selling to recording studios, comparing his ATC wares to everything else available at the time, so did know a good bit about the pro industry that most of us here don't - in fairness. Anyway, he is quite capable of fighting his own battles so I'll say no more.

    I bought some limited edition Celef speakers from HiFi dave twenty years ago, rebuilt the crossovers and enjoyed them for a while. these used an 8" Volt bass driver in a 25L or so ported chamber, a 5" white coned SEAS or Peerless (can't remember) midrange unit in a separate internal chamber and I think, an Audax tweeter. Once the crossover was repaired, the sonics were very like I have now and similar to the better B&W's - upper mid laid back in balance with a sort of "saddle-back" response, which so many Pro-Acs (same designer) exhibit, along with the Beuleau's I suspect

    They were the best speakers Celef/ProAc ever made. They weren't intended to be a 'limited edition' but a very poor review in one of the mags of the time, sealed their fate. Only ten pairs were made and most of the customers who bought them, still use them.

    Your brain cells are failing you about the drivers - they used a 12 inch Volt, an 8 inch Peerless and a 1 inch Peerless dome which I used to augment with a Piezo tweeter tacked on. They were very good indeed and I should never have sold them...

    The IAS cabinets in question were 1/4 wave horn loaded, not a transmission line! They used no dampimng in the line at all!
    The bass driver was a Volt B250, 8 ohm type.
    I know a lot about these cabinets as I used to be part of the R+D team!
