Hello all! Thanks in advance.
I want to use a MiniDSP 2x4 rev b. for bass management of 4 subwoofers.
1. Can 1 MiniDSP do unique settings(phase, delay, LPf, HPF plus EQing) to 4 subwoofers?
2. Which add-ons would be needed for the task?
3. What type of slope does the MiniDSP have for it's natural 5 HZ roll-off?

Lets see, I have two subwoofers and my centers crossover on one MiniDSP 2x4. It has two inputs, each input has two out which can be independently equalized but they're from one input signal. So yes, with two signals going in and four out you can equalize four subs independently. The normal interface only goes down to 10Hz but the advanced plug-in can accept "biquad programming" for going lower than that. I personally don't understand the need to go that low (maybe its a macho thing?) but to each their own.

Which add-ons would be best? It's not a macho thing its just that if its not needed or only 5 hz is needed I want the option. That's why I ditched Iphone for the EVO(Android) LOL. I like options.

Hello,

In answer to your questions and following the very good answer from Theresa,

1. Can 1 MiniDSP do unique settings(phase, delay, LPf, HPF plus EQing) to 4 subwoofers?
ANS: Sure, simply get a miniDSP + 2way Advanced. However remember that miniDSP is a 2x4, so you can only have 2 inputs (e.g. 2 x subwoofer feed). If you have only a single source (e.g. sub out from your receiver), then select the 4way Advanced and it will be even easier.

2. Which add-ons would be needed for the task?
ANS: miniDSP 2way Advanced or 4way advanced

3. What type of slope does the MiniDSP have for it's natural 5 HZ roll-off?
ANS: I'm really not sure that you'll ever hear something at 5Hz! Even a measurement system will really struggle to picture these frequency, either ways, the natural roll off isn't steep.

Hope this helps,

thanks!

miniDSP is perfect for this! I've been wanting to do it for a while. Probably will go with Balanced 2x4 as high-power ("pro") amps typically have balanced inputs.

Yeah, I have pro amps but, I ordered the 2x4 Rev b because I already have xlr to rca cables. I currently use them with my EQ2 and Reckhorn B1.

Sorry to say that with adapter cables used it may not drive your pro-amp to its maximum. The balanced version evidently has higher output voltage than the unbalanced.

Wow Theresa, I guess I should have pm'd you from Avs forums because I mixed up the input and output specs. I don't want to run run the Rev b. into reckhorn b1's to raise the output so now I have an issue. Thanks you've been very helpful.

Hi Guys

I was wondering what to compare the miniDSP to and if it can do this and that for me. So ifound this thread to ask.

Can the MiniDSP be compared to Velodyne SMS-1 and the SVS EQ1 subwoofer equalization systems? - that is, if i use a microfone and a measuring program to look at the sound system?

I know that the above are automatic, but a bit of manual work is to be expected.

Also, can it do the same for higher frequencies and correct some of the problems i have with room modes? I see this is mentioned, but i can't seem to find somewhere with a comparison to other systems that are more accepted like Audyssey and Anthem Room Correction.

Also, will the miniDSP be a major flop if used for high quality sound? - i mean, for HD sound (TrueHD), will the miniDSP lower the sound quality?

I would pay 200-300 for a device that does the above - a Behringer DCX2496 ultracurve pro is on my list as well as the SVS EQ-1 and the Velocyne SMS-1.

Anima,

Sorry for the delay in getting back to you but we missed your thread...
In answer to your question, we don't know much of these products and we shouldn't be the one telling you how our products compare to others.. best to let end users

You could see on here and multiple forums (AVSforum, DIYaudio, Hometheater..) that a lot of users are now using the miniDSP in a lot of configurations. You might have some luck to compare especially about audio quality which has been covered many times already.. (in good terms of course..

I think that miniDSP combined with REW will let you achieve a level of flexibility not common for a lot of platforms. That's maybe what you should compare to, what flexibility you have and the tools ( and their upgrade potential) that come along.

Hoping this info helps, as said earlier, miniDSP DevTeam (i.e. the company) are not the one who will compare ourselves to other company, we let end users to be the judge.

Hi "Devteam"

My question is not directly meant for you (allthough i appreciate your input!!!) but more for the consumers who have tried similar products.

My idea is to use the unit instead of the Behringer DCX2496 and use it to calculate a filter that provides a nice in-room response for a DIY speaker.

What is "REW" - sorry i'm not into the jargon yet !

REW=Room Equalization Wizard. Can also be used for testing speakers. One of the best freeware software packages I've ever used. Look at SynRTA from Liberty Acoustics, its good enough to use instead of RealRTA.
