Am I missing something?

[chad.SQ 0]

Well my goal is to complete a 2.1 channel system for home theater/audio. I currently just finished my build for my Fi Q18. I would post pics if I knew how to do it. But past the point. My next goal is to get rid of my Sony A/V receiver and replace it with quality audio components. And I think I have it down, but I feel like I'm missing something. I need an experts overview.

I want an Equalizer, and I guess the ones I have been looking at have a built in crossover in them. How convenient this is the Equalizer/Crossover that I've been looking at

Then I wanted to use one of these amps (haven't decided yet, I will see how I like the Crown I already have) for the speakers that I want to build.

Then for the sub out I will connect that to my current amp

Other than the cables (which wont be hard to put together, just time to find the adapters), am I missing something?

Why 2.1 and you mention home theater. 5.1 is so much more immersive when there aer effects all around you.

Host you picts on Photobucket. Copy/paste the IMG for each one into a post. They will magically appear.

Why do you want an EQ? Is your frequency response not flat? If not, how did you determine it is not flat? If you get a quality home theater receiver, most of the newer ones come with a mic and an auto calibration system built in. My Pioneer is a few years old and it does it. Excellent results. I so use a Behringer Feedback Destroyer to flatten the response of my subs. The calibration system isn't that sophisticated. And yes, I did determine that I needed to use an EQ. I measured the sub's response with an SPL meter and graphed it with a spreadsheet with correction values for my meter.

I guess I should reword "Home Theater" and say I will be using it for movies too. I would say 80% music, 20% movies. And also that the room is only 12' by maybe 10'? Its a little small. I couldn't get the rears to work the way that they should. Not to mention I'm too young and too poor to spend thousands of dollars on a top of the line audio system. I just know that my Sony A/V doesn't give me the sound I could get. I want to have a pretty nice 2 channel system that I can easily say that I got my money's worth.

I haven't really used a device to see if my response is flat or not, I am just using my ears. I just want the opportunity adjust if need be. I could just get a crossover with sub out, but like I said, I want options.

I suggest that you buy or build a set of quality speakers first. You would be amazed at the difference in sound even when connected to an "average" receiver. Since you already built a sub I know you can build a cabinet. Look for a quality design or kit. Designs can be found at DIY Audio, Zaph, etc. but the best I'm ever seen are at Home Theater Guide (htguide.com). They have dozens based on the Dayton RS series drivers. The designers have decades of experience with audio and building speakers. A pair of these will probably cost $500 in parts but they will be comparable to speakers costing thousands.

From there, upgrade the receiver if needed.

If you still want a crossover, you can check out Marchand Electronics for some great kits. Reckhorn has a couple as well. They are available from Creative Sound in Canada.

I was planning on building a set of these speakers. Its a kit but for my first try, I think a kit is for me.

But I don't want a receiver anymore. I plan on hooking up my audio/video connects directly to the TV. Then use the audio out to the crossover, then to the amps.

Connecting your amps directly to the TV will sound like crap. Audio components are added to the TV as an afterthought. Absolutely the cheapest possible parts that they can source.

You mean if it passes through the TV then I will lose audio clarity? I was going to use the TV as basically a preamp.

[JimJ 11]

Not a good idea.

I have exactly one cable connected to the TV, and that's the S-video from the DVD player All the audio is seperate...

I also would recommend some of Jon Marsh's designs and to NOT use your TV as a pre-amp.

Alright...I just googled "Jon Marsh's designs" and many variations of that quote and I got nothing. Is there some secret underground website that I don't know about?
