How to attenuate the alt

kerrysun · 30th October 2008, 06:17 AM

Hello, everyone,
I have a question to need help, I've built up a set of speakers, but the alt is very high, How can I attenuate the alt to get the good voice? I look forward to get advice. Thanks in advance for your comments.

Come again? What is it you're trying to attenuate? I'm not at my best this morning, but alt. is usually an abbreviation for 'altitude', which is local height above a given planetary reference plane; typically, though not invariably, sea level in the case of the Earth. If you live a considerable distance above sea level, there's not a whole lot you can do about the reduced air pressue, short of either sealing & pressurising your living room, or moving house. You could, however, try a humidifier, which will probably help a bit. A large number of substantial plants (rubber plants, aspidistras, triffids etc.) may also be useful.

If we're talking about the driver perhaps being a little too high above your head / ears when seated, try angling the cabinets forward slightly.

If you're talking about the HF being a little too high in level, you may need to apply some correction, active or passive. Exactly what & how will depend upon the design and the rest of your system. (?)

If we're talking about something else, could you be a little more specific?
