Well I tried my S4 the other day and it doesn't pickup anything under the 80hz crossover.

I use SPL mobile on a iPad and it works well.  Free asfaik

There is no way they will be accurate though... Those apps haven't been calibrated :/

Mobile device mics don't register very low frequency so I found them pointless for leveling subs

Calibration will unfortunately always be an issue  :vsad:

Have you tried REW on a pc? http://www.hometheatershack.com/roomeq/

I've only installed it on my HTPC, connected the Audyssey mic to my Xonar U3, and set the mic's level that it reads a 75db in REW. That's where I got.

I don't know if I'm on the right track with REW, basically trail-and-error

I guess I could try that with  a notebook pc, but ultimately a proper spl meter would be most convenient

Major Tech has one, model MT976. Google their local site. A bit pricey but it looks rather nice. I have an earlier MT model which compares well with my Castle GA112, which is a professional meter. If you hang on for a day or two I'll do a bit of digging in my Alladin's garage where I have another Castle unit, albeit a different model. It may be something you could use.

Thanks Stan, I've poked around the web and the best bet seems to be amazon.co.uk for anything under a grand. Crazy, just to setup the sub and speaker levels....

Park your cat in the listening position.  When his/her ears go back, then the level is too high

That model is their "economy model" at R1755 which is a very good price for a precision instrument.

Their "pro" model is actually on special at the moment for R2848 (normally R3756).

I happened across a MT975 (the pro model in the pics) this morning in a second-hand shop. Neat condition, still has the protective film over the readout. This is in Blackheath, Johannesburg. Not sure if I'm allowed to mention price here, so I won't. Send me a PM and I'll pass on the details.

This topic is quite interesting to me, since I have also done some experiments with dB Pro on iPad and wanted to know to what degree it was accurate. What I did read at one point was that the mic on the iPad was frequency restricted up until a certain OS software update (I'm not sure which version anymore though - but if your OS is up to date I think the mic is less restricted). What I do want to ask here is if anybody has experience with the mic and USB soundcard that comes with the B&W DB-1 sub. It looks like a fancy bit of kit that could probably be used for more than just calibrating the sub. I was wondering if anybody has experimented or found something online perhaps? Don't know if the mic is tuned to low frequencies only?
