Cinema processors that manage multiple subs

[Kingrex]

I have a friend building a home theatre. My understanding is Subs are the hardest part of any installation. He is looking at a Marantz Amp 20 and AV20. I was advocating more than 1 sub to get even distribution of bass in the room. The room is probably 18 feet deep and 25 feet wide. Is there a processor that handles multiple subs and has a built in measuring system that will integrate multiple subs into the space. He has one Def Tech sub already. He is open to others.

Suggestions on a processor and subs to integrate into the system.

depends on the budget.

the best one for that is the Tinnov Altitude 16, but it's not cheap. it can handle any subs. in my system the Trinnov handles 3 Funk Audio 18.0 subs and does a great job in my 9.3.6 multi-channel Dolby Atmos system.

Consider front left/right speakers with built-in powered subs and configure them for full range.

Then add the subwoofer on the LFE channel. The sub can be placed on the side or towards the rear of the room.

Can be more cost effective than multiple subs.

Some subs will calibrate themselves, then just need to set the volume level in the processor.

Several processors handle multiple subs, but they are way more $$$ than the Marantz. The above suggestion works with one sub output.

Isn't 1 sub prone to the same issues as a 2 channel system. There will be a sweet spot for bass. And other seats may be, not so good. Won't more than 1 sub give even response in the room.

the best dsp approach can set up a room for a single seat or multiple seats. and include the subwoofers. depends on your expectations.

I was proposing 3 subs. Two built into front left and right channels that get front channel bass signal. The one subwoofer gets the .1 LFE signal. There is some overlap when the crossovers are set with this in mind.

I use one subwoofer in the front corner and two of the side rear speakers have built in subs and are configured for full range. Works great.

One would have to try it and play with the sub position and tuning.

By the way, the AV20 handles 4 subwoofer channels. Just need to choose another sub, which depends on budget and space constraints.

Speakers are already in the walls and ceiling. Paradigm. If the AV20 handles 4, do you think it will room correct all 4 for even response at multiple locations.
