@ That track’s bass can sure do chaos with the right system that’s for sure. Considering that there’s many people in KZbin using this track, I don’t think a copyright should be an issue.

You can easily fix the passive with the separated spider, but I'm sure you know that. What amp plate is that?

Nice kits for people who don't know much about woodworking or measurements, but want to build their own subs and sound good too. I couldn't build a second one because I don't like being limited to one shape or limited woofer selection, etc... I just bought some Thiel drivers, practically brand new that a guy bought in their closing auction and only tested them to make sure they worked. They're the ones that go in the Thiel SmartSub 12.

Doesn't adding the weight increase the fs not lower it?

Fs is known as the resonant frequency (the frequency that the driver/passive radiator is the most comfortable vibrating at). Adding weight lowers that resonant frequency.

⁠🤔 Not bad considering the return on quality of bass… What would you recommend for a theatre style setup, something in a 20’ x 20’ size room with about 10 seats?

[@righteousbuilds3576]

I'm using a speaker power sp1-2400ht. It's rated at 2400 watts at 4 ohms, but its also 2 ohm stable, so it'll push more than that when it wants to. It's pushing a 2 ohm load on that driver right now. I'm not sure if you've ever worked with 1 inch baltic birch before, but it's very rigid. I'm not super concerned about flex with the amount of strength that the wood offers.

@@righteousbuilds3576 Ok cool,didnt realise the timber used etc. My only experience is with RELs. I have a 2 channel system,1 amp per channel thats plenty but when the RELs are on its a whole different ballgame. I feel tat sub placement in the room and making sure everything is in phase makes as much difference as a brand new sub of double the size. Thats the issue with car audio for me. There's not enough Internal volume inside a car for the subs to work properly. Love the channel. More please, 👍
