    This is not completely subwooferish so mods move if neccessary.
    Many months a go I ordered an analogue spl meter from Keene Electronics and they said they were waiting for stock.
    I got so fed up waiting that I actually managed to borrow one from a forum member who lives in Scotland!
    Keene eventually told me that Radio Shack were moving their European output to Greece but that was ages ago and I forgot all about it.
    Today however I woke up to find curvy new meter has arrived and only £27.49 too inc p&p.
    I know a lot of new subs have been purchased lately so do yourself a favour and get calibrated cos it looks like they are back in stock :smashin:

    I can't think of anything more on topic in a subwoofer forum than a recommendation to buy an SPL meter. :)

    Just remember to use the bass correction figures when you all get your own
    meters. SV Subwoofers website kindly lists the corrections (see link below)

    Surely the new meter would need different calibration details though?

    I wonder? :blush:

    I was assuming that this was the original analogue Realistic/Tandy/RadioShack type SPL meter that Pollywoggle had finally received. :)

    The weakness here is the bass roll-off of the built-in microphone. There has never been any attempt by the manufacturers to adjust the frequency response in the past.

    Only by amateur modifiers. Which lead to some instability. :rolleyes:

    The consensus is/was that averaged across many meters the published corection figures still stand. :smashin:

    He did say that it was one of the curvy new ones :)

    Getting a flat frequency response is obviously very difficult at a budget level in these things but I'd be VERY surprised if the same correction values were valid. They're probably close but is there any way to source some new ones?

    Yes I might email svs and ask about this as the exterior design is different though I am not sure how the inside components have changed if at all.
    That said, these devices are not ideal for this kind of thing and I am not obsessive about such matters anyway, a reasonable calibration has to be better than none at all I guess.
    I used to try and judge the speaker levels by ear and was amazed at the difference when morg lent me the original meter and I balanced them "properly".
    I migh try asking Radio Shack if there is any real difference to the new meters?

    If it's different then it's going to cause huge problems for people trying to understand "New" and "Old" calibration settings :eek:

    They're reasonably accurate down to about 40Hz but I think results should be taken with a large pile of salt below that for all affordable SPL meters :)
