Looking to upgrade my sub (currently have a Jamo sub from the a102 hcs system). Looking to spend up to £500 and it will be for 50/50 music/movies. The room is about 17ft x 12ft. What would you recommend?
You can buy a new Monolith is £475, although some finishes cost more. I suggested the XXLS400 due to your 50% music use. If you have a search you'll find a old threads here with people discussing the Monolith vs XXLS400 question that you might want to read.
I have a Monolith that I'm using for music as I type this but I haven't heard an XXLS400 to compare. Sealed subs (like the XXLS400) are generally suggested as being better for music by virtue of having a better transient response, and I'm keen to explore this myself when I can.
I'll add that I'm using a miniDSP 2x4 HD to EQ the bass (amongst other things). I don't think I'd want to be using the Monlith for music without this.
