Rather than reply in the Monolith thread (which I have read in full) I would like a new thread so I can easily refer to the answers for (as you will see by the questions) I am a complete novice. I'm about to confirm my DF Monolith order on the 2nd of January. This is the first time I will have a decent sub and I'm a bit overwhelmed by the amount of variables involved in setting it up. My first sub on a complete budget system was an older version of the Mordaunt Short 309 and I thought it sounded great I'm hoping to be blown away (literally) by the Monolith. Questions in no particular order: 1. I'm not too sure about setting all my speakers to small when surely that's why we edit the cross over? Should I still set them all to small? It will feel strange setting my GR60's to small? It will also be a pain as I don't have a dedicated stereo amp so I will have to set them to large when listening to music unless any Z9 owners can help me out? 2. Should I choose 80Hz as a starting point and adjust from there or is there any other starting point that you can recommend? I know 80Hz is the THX recommended setting is there an optimal settings for my speaker set? What does anyone think would be a good benchmark? 3. On my amp I have the option of choosing THX Ultra2 Sub. Can I choose "yes" even thought the Monolith hasn't been certified? If I answer yes to the above it leads to further options: 4. Boundary Gain Compensation. My Monolith will be placed quite close to a wall (almost in a corner) so I presume I should select "On" to make benefit glorious choice of having the Boundary Gain Function? or should I alter the "gain" using the Monoliths settings? 5. Is this the right way to connect it up? Power Off. Connect from Z9 "Left Subwoofer Terminal" to the Mono input on the Monolith using RCA interconnect. Turn "High Level Gain" to the minimum position. Turn "Low Level Gain" to the minimum position. Turn "Frequency Contour" to maximum position (120Hz). Turn "Phase" to 0 degrees. power On. High Level and Low Level Gain: According to the Monolith manual I should adjust until the level of the bass from the subwoofer matches the level from my speakers. I don't really understand this because if all the speakers are set to small, crossover is low and I've directed all LFE to the sub, surely there will be no bass to match with? Frequency Contour: Adjust counter clockwise until the output from the subwoofer meets the lowest notes from your main speakers (crossover point). Again same question as above. I'm trying to be as prepared as possible for when the Monolith arrives so it would be great if you can give me any suggestions or advice to the above. Apologies for being all over the place with my questions Cheers in advance.
