    Make sure to use a cardboard enclosure with an airhole.

    Im curious as to what speakers are in your setup guy. Are you using lsi and the rti series in the same setup? I thought mixing the two speakers would cause an inbalance since they dont match, etc. Any with outake on this?

    You live and learn I admit after reading my post again it didn't make sense.
    Using the bottom posts of the Rti10's for the bass didn't help my cause any either.

    I just turned 21 it hasn't been six months since I've had my first Receiver, and Rti4's were my first pair of speakers. Anyways I admit making a few mistakes in audio so far like getting the Rti series instead of the Lsi's. Well my system sounds a lot better than it did last week, just need a sub.
    Setup:

    2 Channel: Vienna Acoustics Mozart Grand, T+A P 1230R, Primare SPA21, Oppo BDP-105
    PC: Vienna Acoustics Haydn Grand, Cambridge Azure 650A v2 , Peachtree iDAC, Denon DVD-3800BDCI

    LOL I guess I'm not the only one asking stupid questions. Hmm lets see Rti10's Csi5, Fxi5's those seem to go very well together for 5.1 doesn't it genius.

    A pair of Lsi7's go very with music also.

    Any other questions guy?

    Can't remember who, but somebody recommended going to CC or Best Buy and getting a cheap Yahmaha sub.
    Don't know what your budget is when you say you don't have much money; for some folks that means they only have $1000 saved up, for others that means they only have $100 saved up.

    If you have $149, get on Amazon.com and get ......

    here it comes

    an Athena AS-P4000 subwoofer. DELIVERED.

    It's not the be-all and end-all of subs to be sure, but it'll satisfy your need for a sub for now.

    90% of our usage at home is for HT, and for movies you definitely won't be disappointed.
    For music, well .... you shouldn't be using a sub anyhow.

    Scout out Ebay, etc but be careful of shipping costs.

    The RTi4 is not a subwoofer. It could NEVER be a subwoofer.

    It cant even be a freaking BASS MODULE. That thing atleast hits to 40hz.

    The RTi4 with its amazing 60hz roll off would roll off before your LSi7.

    haha this is a great thread (and obviously just a way to get my amazing post count up :D ).

    Honestly man, it wasn't the question itself but HOW you asked the question that got it flamed like it has been. It's not what style of cable you use to hook a speaker up that makes it a sub or not, it's what frequencies can a speaker play and if it has a built in amp that makes it a sub or not. So take this thread for what you will, but just rethink your questions before posting. At 21, I figured the common sense would've stepped up and said "WTF?" before hitting "Submit."

    First off it isn't common sense I figured someone your age should know that. Perhaps you should make better use of your time, than worrying about your post count.

    However I do agree about rethinking questions before posting them.

    Hmmm. I don't know where this post count comment came from or why it keeps coming up but it is the farthest from the truth.

    So have you figured out how to use your dvd player as a tuner yet?

    Hey guys, my maggies are only hitting down to 22Hz in room. Should I use a Bose cubes as a sub to help it out?

    Sorry Krazy, but this was one ide that should have been shot going out of the gate. The 7's will give you decent enough bass with good amplification unless your a big rap guy. Save up and do the LSi's right by providing them a good sub to play with.

    Great thread... I can picture Sid having an aneurism at 16...

    Krazy,

    If I were you, I would email Polk_Audio_Lsi for some ideas. He's a great guy to work with; much better than these other grizzled old farts. A real outside the box thinker. . . could turn that RTi4 into an SVS Ultra in no time with some super-sweet wiring tricks :)

    My curiousity is tweaked - are you guys serious? Does it work? I am good enough with wood that I could actually build it. Tell me it works, and I might just make is a "winter" project.

    Hell yes...

    The way it works...

    The full range driver produces highs, mids, and bass...

    The backwave of the drivers goes down that "horn" so to speak, it loads up in the slender parts and by the time it goes out the large opening it is amplified - and I imagine there is fill lined along the walls to get rid of the higher frequencies so it is all bass...

    So basically you will get amazingly clear highs and mids with loads and loads of punchy, accurate bass that is absolutely effortless...

    I don't see anywhere that points me to drivers, etc that I would need. Do you have a link for those? Or, do you have other suggestions?

    Sid, you build speakers - what would you use? Would you do this project?

    I believe the ones used are Fostex - but I may be wrong.

    Thats actually a very "famous" so to speak project, so google should bring you up results.

    Thats basically a transmission line design basically...

    Would I do it?

    Tough question... I think Id do a more traditional transmission line - to many angles in that one. Unless you really like that kind of thing...

    If you don't mind, point me to some of these other DYI's that you like. I know you have spent a lot of time and energy researching these and maybe you can help me out. I will build a pair and offer them up here on this site after I want to do another project...

    The problem with using the RTi4 as the sub is that its not timbre matched to your LSis. Its going to provide an odd sounding bass that you surely will not be pleased with.
