Good day,

Am a newbie here. Im from Manila, Philippines. Need some help from the gurus here who are knowledgeable on Altecs. Recently (and cheaply)got a pair of 515b drivers (16 ohms) and a pair of 288-8g (8 ohms) on 805b horns. Can anyone suggest what cabinet design and crossover design is suitable for the mentioned drivers. I'm not so sure if the Altec A5 (828b or 825) enclosure design would do. Also what dividing network will work on this? Im a dimwit with technical stuff but I do have good hands for cabinet making.

Another question is, since the HF driver is 8ohms and the LF driver is 16ohms, what can I do about it? My guess is is that the pair 515b drivers were initially just for one speaker connected together to make it 8ohms. The other pair must have been sold somewhere else. Is there a way to use the LF and HF driver with different impedance?

Would appreciate your help.

Many thanks,
Earl
