Best speaker for guitar that sums Bluetooth and Aux in?

Looking for some advice on my guitar setup. I currently have all my pedals running into a Walrus ACS1 amp sim pedal, which has a headphones output for silent practice. However, I'd like to amplify the sound in the room and also practice along with tracks from my phone via Spotify.

Ideally, I'm looking for a speaker that can handle both the signal from the ACS1 (via aux in) and a Bluetooth signal simultaneously (and sum those to headphones). Any recommendations?

1. Do you need battery power?
2. Do you already have a decent stereo sound system in the room you want to practice in, or does this setup need to be pretty portable?

No battery needed.

Portability isn't paramount, but if it was compact that's a plus. I have a soundbar and sub for the TV but that's in a separate spot.

Something like a Positive Grid Spark vibe comes to mind. But I don't really need it to be a guitar amp with effects, which is what the Spark is... but that form factor is cool.

If this had a headphone out, we'd be pretty damn close.

Yeah, the headphone out is the toughest part. A product designer would probably get laughed out of the office if they spec'd a consumer-focused BT speaker to have a headphone out jack. The assumption is you'd just connect to your phone directly if you wanted to use headphones.

A suggestion from out of left field:

They sum everything, they have BT, a stereo line in, and a headphone out:

Not sexy (in a way non-MI people would recognize, at least), not portable, but they check off boxes. Presonus is fairly trustworthy for speakers too.

I'll keep pokin' around.

Also, this guy is more traditional BT speaker from Roland. It still has some guitar tone affordances, but they can be bypassed via aux in, just like all the other products of this type. I can't find 100% confirmation in the manual that it can do aux and BT at the same time, but a review I came across stated it could do "all 3 inputs at once".

It's cheaper than the Spark, but that's maybe all it has going for it. Vibe-wise, it's got a Chanel/Louis Vuitton thing going on, which is... something... IDK...

You sure you don't just wanna go with the Spark?
