I'm still gathering up all my parts for my HT. I'm looking towards building a Tumult based PR
sub in the spring, but for now I purchased a HGS18, used from a reasonably trusted source that from all physical appearances is in perfect condition. It may ultimately do me just fine - hope so, it's a finely built thing.
I need some help with 2 things:
1. The manual isn't clear on how to hook the sub up to a processer with a single sub-out port. I tried the left and right pre-in's which seem to work, but I read a setup article on audioholics that said I was supposed to use a Y adapter to feed both pre-in's on the sub for a 6db gain. Is the correct? What is the best way to hookup my HGS18 to my single sub out connection on my processor (B&K AVR507)?
2. It being used, I would like to verify the sub is functioning properly. My HT area is not done yet. Presently my "temp" setup is in my wide open basement that's about 1400-1600 ft2 with ~10' ceilings. I bet 14,000+ is a lot of cuic feet in sub terms. I do have a sound meter and have the jist of it's use. On some sample soundtracks (i.e. Blackhawk down Fing Irina scene) the sub just dosen't seem to much output, definately less than expected, even considering the large space. But I'm new to subs (my first) so I dont' have any experience on what's proper. It will be several weeks before the HT space is enclosed. I'm not so much worried about tuning the sub for performance right now as I am wanting to verify it is working properly. Is there a way I can do some simple tests to determine it's functioning properly, quick and cheap? FWIW, I have Avia, VE, and DVE DVD's. I tried Avia's sub setup tones, and the sub seems to do fine per my SPL at 70db. But I dont' know how to push it closer to it's max outputs and lower freq. limits (and check it). I've seen reviews with folks sitting outside testing subs, I can do that if needed to test the sub is functioning properly, just need to know what to do.
If it matters, I'm using a B&K AVR507 receiver and a Denon 3910 DVD.
Thanks very much as always for the time to help,
