I also imagine it will make life easier dealing with the modushop if you make this request.
I'm assuming FedEx is working the location issue with the driver, but like I said, I have zero faith in their ability to find it.

Hurry up and wait, I guess.

You don't need the results of a conversation with the driver you need the location data automatically generated when he or someone scanned your parcel barcode as delivered. This is available right now if you call FedEx!

I don't see it as my job to find the box they mis-delivered! I checked the small store in my building and the apartment next door. Now it's on FedEx.

ETA: Just got a call from FedEx, they are at least looking for it!

I suspect you will still be short on free air cooling with your revised heatsink.
Thank you, very useful information (that I probably should have already known). I'm not sure where I came up with the number, but I thought it was 20 watts per board. I guess what I will do is start by temporarily mounting both boards to the new heat sink, with out any other fitment for the case, power them up and just monitor the temperatures. I know cooling wouldn't get any better if I trim it down, so if there is insufficient cooling at that point, I won't waste any more time going that route

Thank you again.

My pair of ACAs are on the 2 outer shelves, a big part of the appeal for me was the small case to fit the amps on the shelves. I went for the deeper version of the case to compensate for the lack of airflow and all seems fine temperature wise.
My favourite speakers are however the TABAQ with P830987, I have these in another room with an F5. Worth checking out the long running TABAQ thread if you are unfamiliar, they must be the best, simplest and cheapest diy build ever!!
Coming from a world of multiway speakers with crossovers, my brain really can't understand the single full range drivers. Not to mention I have dual 21" subs and can't imagine any fullness on the bottom end without some support from subs. They must work but it seems illogical.

I'm in the middle of a Elsinore build that is sitting idle in my shop. Its a mildly complicated cabinet with a complicated crossover (at least to me). I keep looking at the full range driver options thinking I might try a pair to see what they're like. Thanks for posting the pics. Nice set up.

You can certainly use your subwoofers with a FR satelitte. You’d only need to getthem down to 80 Hz?
