Hi,
I've run a lot of subwoofers through WinISD to find the right one which met the needs of the audio system being installed in the car. The goal was to produce a very deep subwoofer that drove 25 hz to 80 hz effectively. In looking at over a dozen drivers I came up with the Boston Acoustics SPG-555 2 ohm. It's going to be run in a 2009 BMW 535i, but needs to be ported through either the rear seat arm rest or up through the rear deck. The car has a lot of steel and really deadens any sound in the trunk, so I felt I'd lose too much sound quality unless it was ported into the cabin. The last car I had, the previous gen E39, ran a JL Audio W7 firing through the ski pass, but that wasn't an option on this car unless I cut the whole for it...which I want to avoid.
So, do any of you have WinISD and can look at the attached file to provide some feedback on the performance graph and if I did everything correctly?
For those of you who don't have access to WinISD I have attached a bunch of photo's showing graphs and specs.....
Does this look like a good set up? Am I missing/forgetting anything? Thoughts, concerns, impressions?
Thanks for the feedback, appreciated!
