Altec 604 D Enclosures

[charly1944]

For real?! That puts the tuning up around 72 Hz whereas a typical Altec tuning would be around 40-42 Hz.

Thanks GM,
Pretty high tuning indeed.No wonder that i found it could have gone lower in the bass.What options would you recommend to go for.I dont mind wether it is an OB (provided it is not too big) or a BR solution.Thanks.
