Deal Details
The List Price above is from the vendor and thus optimistic, but Amazon usually carries this for closer to $200 so this is still a nice deal if you can wait around 9 days for it to arrive.

Full details from manufacturer website: https://fosiaudio.com/pages/zp3-preamp​ [fosiaudio.com]

This is a relatively low-cost solution for someone who already has a pair of powered/active speakers (or passive speakers with external amp) and wants to add up to 3 additional sources, plus have a bass-managed subwoofer featuring an ingenious high pass filter controls on the bottom.

Next step up would be the Wiim Ultra pre-amp which does offer a ton of both wired and wireless connectivity options, regular price around $330 on Amazon.

I dont see a low pass mentioned. The high pass can be set to 80hz or 120hz. The sub output is full range so you'd need a sub with lpf control

No. Most subs already have a low pass filter. This gives you the option to put a high pass filter on your mains, which can make it easier to dial in a sub, and is a huge deal if you're using smaller bookshelves or other non full-range speakers that can really struggle with low frequencies.

At that $299 pricepoint if you want to pay full price for quick shipping from Amazon not wait for Ali Express slow shipping, you might as well spend an extra $30 for the Wiim Ultra pre-amp which has many more features and proper bass management (high pass filter) which is huge if running small bookshelf speakers with an active subwoofer.

I honestly don't know of any subs that do not have their own LPF. Even $100 Jamo or $200 Edifier T5 have LPF.
