As I was perusing the Parts-Express website, I came across these. They're about the size of a matchbox, and cost $60 per box. Each box can control single or multiple subwoofers. The box contains its own signal generator, analysis software, and memory to store the data it collects. Its software is downloadable for Android & iOS software. The box corrects not only the frequency response of the sub(s) as measured near field, but also its in-room response. The user can choose not only the frequency but also the slope of the crossover. This is academic if you have an AVR or processor. Your room-correction software does most of this for you. But if you've a stereo system and don't use an AVR or processor, this device offers a number of advantages: - It affects the subwoofer only, and therefore can't mess up the quality of your main speakers
- It does its own A-D / D-A conversion from your preamp out signal
- For the price, it can do a remarkable job of compensating for non-linear subwoofer frequency response
- You can choose (or not) to let the box room-correct
I got both my subs equalized, room-corrected, and crossed-over on first try, and the results sound MUCH better, thank you. I'll be writing a full review of this device soon, but for now - you might want to check it out if you aren't familiar with it! This is the sort of product that I wish Emotiva would have offered first. www.parts-express.com/dayton-audio-dsp-lf-low-frequency-dsp-controller--230-520 |

This reminds me of the DSPeaker product “Anti-Mode 8033S-II” at a much less expensive price point.

Boom, Mayhaps a stupid question;
Can this be controlled via pc,or even a kindle fire, if I don't own any Apple devices?

Boom, Mayhaps a stupid question; Can this be controlled via pc,or even a kindle fire, if I don't own any Apple devices? Android phones, yes - but you won't get good calibration. Different models of Androids use different microphones. All the Apple iOS devices ever made use exactly the same microphone (according to Dayton). So were I you, I'd call Parts-Express and ask. The bottom line is that I don't know off the top of my head. I didn't notice any instructions in the quick-start guide mentioning anything but Androids and Apple stuff, but I might have just missed it... Also, the mobile device is used ONLY for setup and initial calibration. After that, the box is independent. You might borrow someone, and their iPad for an evening? |

First impressions... It works and is noticeable! I have an in-ceiling sub in my 2ch office rig and it's nice now having control over the sub at my finger tips. I've gone through near-field and linear so far and it does a really good job. For the price its amazing. I used my ipad to run the calibration and so far I'm impressed. Thanks for this! |

Yep I heard of these too. Way cool. A solution that makes sense and not costing the bank to get it either. Wins all around.
