Need a Sub for my setup (Xonar STX + M-Audio AV 40's) - Page 2

Setup won't be too bad. Get a 3.5mm Y adapter and a 3.5mm to RCA cable (mono, or get a RCA Y adapter to convert it to mono) for the subwoofer. If the subwoofer happens to have stereo RCA inputs, then forget the mono part. You'll need to use Windows to control the volume. It's not the most optimal of ways to do things, but with active speakers, that's the only way it'll work.....well, at least without physically modifying your AV40's.

To make a long story short... what would you do? Personally I want to make it simplified... and easy to use, but also sound wonderful. At the same time I don't want to drop a ton of money.

I would be willing to sell the STX and M-Audo AV 40's if it meant I could target a better suited setup for not much more than what i would get out of them.

Also, one other thought I would throw out there. In a few weeks I will be moving. I will be placing both my computer and my wife's computer on a couple Z-Line desks (yes, the infamous Staples desk). One setup in an L while adding one section to one side for my desk. Above the desks will be a 46" LCD TV that currently is in my bedroom by itself (plus BR player and WDTV Live). So when my computer room and bedroom end up one in the same when I move I could potentially run my computer audio and TV audio together. But, from what I could tell it means buying another receiver and an external DAC for the computer so I can use the headphones while the wife watches TV. Thus I can switch signal to the receiver or to the headphones. And the TV would be through the receiver anyway. So anytime I use the TV I couldn't use those speakers for PC. Don't know if that would be annoying or not (how many people use speakers for PC and TV at the same time?). And to top it off it means buying speakers + subwoofer still (assuming these AV40's would be inappropriate). But, I could sell the STX for the external DAC and the speakers for another set if needed so the only expense I would not be planning for is the receiver. That is if I thought everything through.

Granted I would be willing to spend $100 on a sub. So, the only difference is if I need to sell these speakers and buy others. And if I had to buy a receiver maybe I could find one cheap enough for the job that needs done. Just not sure what that would be, but I do have some BB credit.... lol.

If I set the frequency for say 80Hz, then will the RCA out to the AV 40 Speakers run their normal mid-high's so the sub runs lows and pass on regular audio to the speakers?

Yes a crossover freq of 80hz means thru RCA/speaker level out 80hz and below are stipped from the audio source and passed to the satellites

Good. Thanks.

I have decided I will buy the sub as the complexity of wanting to drive audio from the TV to the PC speakers and retain certain abilities is simply not worth the hassle and actually places limitations unless I am driving video to my TV from the PC which I am not. I am putting a BR player and HD DVR hooked up to it which means a receiver would be switching not only audio to the PC speakers, but video which is not optimal as it means essentially I watch and LISTEN to the TV or I DON"T watch TV and I get audio from my PC through the receiver. Bad plan unless I can just pass audio from the TV to the receiver. And even then I could only watch the TV, not listen to it, if I had the audio source switched to the PC.

So, through the whole headache of considering all the complex options (and I don't like complex when something doesn't need to be) I think I will just get the powered sub and strictly use the setup for my PC while I get a soundbar for my TV in the future. It is just my bedroom after all and not my home Theater system.

One last question....
Given it is an 11x17 room on the second floor, but a room away from the neighbors, what size sub do you suggest? 8 or 10" I still want to have decent base, but not rock the room two doors down.

Well not all subs are created equal but for flats/apartments where u dun own all the walls i would think look for front firing subs ^^

We will be in a condo (end unit) with no one below/above us, and on the outside wall.

You know where I can get that for $100? Would an extra $25 or so buy me any better quality? Like HSU or something. Also saw BIC, but don't know how they rate.

Whoa u not gonna get a brand new HSU for $125 brand new but hey the beauty of used hardware is you can always have a shot at fishing out a gem so happy hunting

Any other brands I should look for? I assume HSU, Velodyne, and Dayton Audio to all be pretty good. Bang for buck top end is always nice.
