Re: So I built this...
Nice job! Would the sound benefit from some damping material added to the enclosure?

Doc, I have already seen one of the Cybertrucks wrapped in a rusted patina.

Re: Help finding an amp for Sda Srs 1.2
A 1000wpc amp in your price range means a pro amp and you don't want one of those.
For every 3dB increase in volume it takes twice the power. So, for a 90dB @ 1 watt efficient speaker such as the Polks in question to obtain a very loud 107dB would take 64 watts, to obtain a hearing damage level of 110dB would take 132 watts and to cause permanent hearing damage at 119dB would take 1056 watts.
Quality over quantity wins the day, every day and twice on Sunday.
What are you using for an amp right now?

Set up properly, they will transform what expectations are and change the path of your audio journey FOREVER. Do not buy these if you are content with what you have. Buy them if you want to find out what you have been missing and are not afraid to allow your ears to gain control of your wallet.
Great speakers, great seller, and a hearty congratulations to the lucky new owner!
That's exactly what happened to me... hence the 1.7i's. Truth be told though I was very, very content with the LRS but when that smoking good deal on a 4 month old pair of 1.7i's landed literally in my own back yard I couldn't resist.

Re: 1.2 to 1.2TL
Untouched OEM crossover
The largest choke is mounted to the center plate and the board is mounted to the choke with plastic standoffs.
For the rookies who don’t get it a choke is a specific type of inductor as there are many kinds. Everything used in a crossover is a choke. Some are there to smooth current and some are part of the tuned LC and RC networks and some yet to simply filter noise.

Re: So I built this...
Don't know yet how long the 3 18650's will play, but I've run them so far for about 4.5hrs. I don't think these are the "protected" type, they are Li-Ion--this is actually my first device that uses 18650. I Bought them from Parts Express, along with the battery board.

Re: So I built this...
18650's come in many colors, it's not necessarily indicative of the size/type. It's more indicative of the brand and the mAh ratings.
But if that battery module holds three 18650's, though, then that's a 12v power supply.
18650's are 3.7 VDC Li-Ion so 3 of them gets you to 11.1VDC, not quite 12v but serviceable for a portable stereo box. Should last a few hours with three 2600 mAh batteries and the t-class amplifiers. They really don't draw that much, especially when you're using efficient drivers.
And I'm not going to need a big battery either. The kit I have came with 26650 5000mAh Li-ion batteries, five of them. At 3.7VDC each, that's 18.5VDC, plenty of juice to run a 210 watt t-class amplifier circuit for casual listening at the pool or something. Plus, the battery board will run off of an external 21 VDC power supply too.
