Is this connector available in a passive format without the transformer for use with you 8 ohm rock speakers?
If , not can this be used simply to weatherproof 8ohm rock speaker connections?

Hi Greg:

Have you checked out our AquaBlue Direct Burial connectors, I believethey would be your better choice. The outdoor 70V Transformer is rather big and bulky and three times the cost of a pair of the AquaBlues.

What is the frequency range of this transformer
By Customer Service - Q&A on April 12, 2012

Hi George:

We are assuming this is the Frqency Range...65Hz - 20kHz. We are trying to verify that with our manufacturer.

How do I mount the transformer? I do not see any clips or brackets on the item. This is going to be mounted outside.
By Customer Service - Q&A on August 29, 2012

Hi Miguel,
Typically the transformers are buried with the speaker cable underground. We do not carry a bracket for them at this time. You should be able to retro-fit your own mount if necessary.
