Sub? Can't Decide


Looking for a sub for a small room,approx.10x10.No vaulted ceiling or anything.I'm looking at a 8" for the small footprint,to keep the wife happy.Really aren't a good way to run a full 5.1 setup in this room,so I am using a Mythos SSA-42 soundbar instead. It will be used for 99% movies.I don't need to wake my neighbors.I know that a 8" won't rattle the walls,but to keep the wife happy,I'll compromise.I am looking at the following...

Outlaw Audio M8
Mirage Omni S8
HSU STF-1

Setup: Denon 1909 AVR
Mythos SSA-42
Sony BluRay

There is a Linn Akurate 221 8" sub on A'gon right now for $995. The retail on this is $3750. I have one in my living room and it is a fantastic sub for both music and movies. It's perfect for a moderate size room -- not big enough for a big room. If you turn the gain low enough, it will fill out your low end in a very subtle way without bugging the neighbors. If you want to spend less, there are some open-box specials on small REL subs on vanns dot com for good prices.
Looking back, I sure wish my apartment-life neighbors had been half as considerate as Elizabeth is! That said, with your Mythos soundbar rolling off at 60 Hz, I think it's clear you should try a small sub.

Mateored is right. Get it dialed in with right placement and crossover freq, then set gain to just above audible. Most of the time it won't be apparent, but will add a base of compression that enhances everything else.

I have Hsu subs and they work with my system (and a great company to deal with), but I'm betting that you'll need something like the high-level crossover and Neutrik connectors, as well as other features found on the small REL's. For instance, you may end up raising sub's lower rolloff freq. due to your 10 x 10 room dimension. Strongly suggest you go for the REL 8" T2 from vanns, etc. per Mateored.
M&K sk 10 8'' 150 watt sub on ebay for 212.00 plus 28.00 shipping. I bought 2 in may and they are great for the money. I offered 190.00 and got the price even though I bought them a few days apart. You'll be surprised how well they work, and they are new.
The Mirage MM8 is a fabulous compact sub in a 9" cube format. True, it won't rattle the walls, but it is so "quick" that it blends easily with speakers that don't go down too low, such as your soundbar. The MM8 is only good down to about 36 Hz, but that's better if you want decent bass without annoying the neighbors. At $799 the MM8 was competitive with quality compact powered subs, but now you can pick them up via buy-it-now on eBay for $239 with free shipping and a 30-day return period.

These subs are so compact and now so affordable. I recommend you buy two for $480. I have a pair of them for my 2-channel music system and they are *really* good at filling in that 35-100 Hz range. I bought them because there was no other sub combining that compactness, quality, and price to sneak into the istening room without having to rearrange gear or furniture.
I appreciate all the replies. I should re phrase when I said wake the neighbors. My nearest neighbor is around 150 feet away. Guess i was saying that I need a sub that would not rattle the walls apart. If that makes sense.I'll check out the recommendations.
