I've got a new 16-46 PC, sounds pretty good set by ear (I've been using sub-sat systems for about 15yrs). I generally start with the Avia setting then end up upping the bass until pleasing. Takes a few days with a variety of materials to arrive at settings for music and movies. I use the 80hz crossover on my Rotel receiver and set all speakers to small. I use Sonus Faber Concerto Homes for my mains. I am using a ten year old RS meter and aged stereophile test disc. Measurements are all over the map with a greater than 10db variation, up to 15 or more increase in the lower bass. No I'm not a bass freak but do listen at lower levels overall which I believe contributes to having to up it so much. I have the stryker disc on order and will try with that. Main problem is that I find it a hassle to use the rs meter. No I don't have a PC at home, use the trusty webtv. Am posting to see if anyone has tried the RABOS system Infinity made for it's newer sub line. Called Cruthchfield, they sell the product for $59.95. Rep stated that the sound pressure meter has a digital type read out, a green bar set against a scale. It measures from 20-100Hz. The accompanying test disc outputs from 20-100 Hz in 23 steps. I have seen a review of one of the subs in which the author states the kit would be a good tool for any sub set up. Sorry forgot which mag. Given that I don't really care what my sub is doing under 20Hz does this sound like a good product? If I could get an easier to use product and not have to do all the correction for different freqs. on the RS Meter I would be happy with the cost. Anybody tried one? Thanks in advance.
