mini DSP which to get for my subs?

How about to use the Onkyo Audyssey for the x-over and get (+-$100) the basic MiniDSP. Since the Onkyo does the x-over, you can use the 4 channels of MiniDSP with 4 parametric equalizers, so you can equalize, delay etc each sub separately.

Currently upgrading my subs ( from (2) 12 and (2) 15 , all different from each other) and looking for some bass management of some sort - and only have a the onkyo 818 w/ audyssey - will the mini DSP be a better way of getting all (4) of my new subs ( SI 18HT) to work together? and if so which mini DSP to get, went to their site and there is lots to choose from( I don't know much about these , so hoping someone can direct me in the right direction) or is the audyssey that the Onkyo has with it good enough for this? subs will be in 2 pairs 2 in front and 2 in back.

I can’t remember if the 818 has xt32 with subeqHT, or just MultEQ. If the latter, than it can’t do two subs individually, or a pair in front as “sub1” and a pair in the back as “sub2”. Which won’t really work if the room/LP/sub placement aren’t symmetrical anyway.
The minidsp/rew/umik combo is powerful. But get the minidspHD since it has more output voltage, and iirc, more filter resolution.

You should check out the Multi Sub Optimizer. It's free.


And read this.

Personally, I have dual subs, and it's supposed to help a LOT for that also.

I'm just thinking of it as part of my subwoofers, which are the pride of my home theater and get whatever they want. (dual IB manifolds)

Hello, The miniDSP 2x4 HD would be a great fit for managing multiple subwoofers in your setup. It allows you to independently manage each subwoofer for volume, delay, and EQ. This lets you tune your system more precisely than just using the Audyssey system in your Onkyo 818, which treats all subs as one. You'll need to also pick up a calibrated microphone like the UMIK-1 from miniDSP to measure your in-room response. This will give you the ability to do advanced room correction which should provide better results than relying on Audyssey alone.

It's not a quick plug-and-play solution, though; there will be a learning curve to get it right, but there are plenty of resources online to guide you through the process.
