Features & Specifications

The ACE840TT, like its younger sibling the ACE640TT, offers excellent stereo sound and takes up half the space of a standard speaker pair, while still delivering smooth, 2-channel sound. The ACE840TT produces more bass response and covers a larger range than the 6.5" version. Works great for whole house audio applications!

Would I notice a difference between this and the discontinued ICE840TT? I have 2 of the ICE840TT's and now I'm installing another home speaker and would like to keep things consistent. It looks to be the same size, just a little lower max wattage.
1 Answer
Hi Frank:

The ACE series speakers feature a trim-less design versus a standard frame. The original ICE840TT was a big seller for us. The ACE840TT has also done well. There should be little to no drop-off. I might have recommended the ACE850 but we are out of this model.

Can you please explain “cutout dimension†means and how it relates to pre-construction brackets.
1 Answer
Hi Mike: The correct New Construction Bracket for the ICE800TT is the NCCB8. Here is how you determine the fit of a New Construction Bracket for a particular speaker. As an example, the cutout hole dimensions for the ICE800TT is 9.0" (as listed in the Specification). The actual outer dimension of the speaker is 10.25". This number tells me I have 1.25" available. The NCCB8 has an opening of 9.5" so I have a difference of .75," but you have to cut that in half to see what the overhang would be; so about. 375" all around. And they both are in stock. You had also asked about backing for this speaker especially if you are dealing with an exterior wall or any wall where there will some form of insulation. We do not have an affordable option for this speaker but would recommend a product from OEM Systems. Here is the link from a company that stocks this product ironically based in San Diego: I hope that helps TL/5438

What speaker wire is required for this speaker? 4 conductor or 2 conductor (2x) connected to amp?
1 Answer
Hi Eric: Either will work, the four conductor is a little easier since it is one wire with four internal conductors. Typically we recommend red; right side positive, black; right negative, White; left side positive, and green; left negative. 16 AWG will work fine (16/4) up to 80 feet. For runs longer than 80 feet we suggest 14 AWG (14/4). 16 gauge works better if you are connecting to an input for a speaker selector or volume control. Note, use either one of the input connections (since they are not labeled) on the ICE840TT, so use the red and black on one and the white and green on the other. Left and right are combined so not critical which input you pick for either. TL/5236
