Rti4 as a sub?

[KrazyMofo24]

Well I been listening to the Lsi7's I could really use a sub. No money for a sub right now is it a stupid idea use one Rti4 a sub?

I could convert the speaker wire to RCA, its for a small room.
Will it hurt the speaker?

Or even Connect both of them and run them in parallel.

Also I could take off the jumpers and run then in the bottom posts.

[VR3]

This is...

The best post, I have ever read on this forum...

I mean this.

This is a horrible idea.

Start saving.

[lomic]

Most people cross a subwoofer over at 80Hz, and the RTi4's -3dB limit is 60Hz. So, you'd get an amazing 20Hz of coverage with a massive 5 1/4" woofer.

Yes, it's a horrible idea, but that's why.

[KrazyMofo24]

Care to give any reasons why it wont work?
Obviously its just something temporary until I buy a sub.

[sucks2beme]

Damn. You are crazy:D
HT or 2.1 channel?
Small musical subs come up on Craigslist pretty cheap all the time in the DFW area. Nice HT subs are a lot harder to find. I found my SVS pci25-31
on Craigslist for $200. If you must have something now, I got a Yamaha
YST-315(cheap). Nothing much, but it will work as a starter for HT. PM me.

[KrazyMofo24]

Fine what about the Rti-10's?

[VR3]

how...about... a sub?

Sell the RTi4 and RTi10 get a sub... lol

[KrazyMofo24]

Well use the 10's temp will cost $5 for one wire at Radio Shack I'm not going to have any money for a good sub for another month or so.

[VR3]

Why do you need a sub?

[KrazyMofo24]

For movies the 7's don't have enough bass.

[millerman 3732]

What makes you think that the RTi 4's will put out any more bass than your 7's do?

[VR3]

Ok... why dont you just plug up the RTi10 for the time being???

[ronnie]

SUBWOOFER.......for sub frequency....you need a dedicated speaker able to go at the least as low as 40hz ....crazy to even think of a RTi4 to do that kind of job.....go to cc or bb and there cheapest sub will do way more than the 4 will do as a subwoofer....no question is stupid, it's just this one is a little odd

[WilliamM2]

Well use the 10's temp will cost $5 for one wire at Radio Shack I'm not going to have any money for a good sub for another month or so.

Are you thinking of driving this "sub" from the RCA sub output of your reciever? That won't work at all.

[ronnie]

the 10's don't work like that

[KrazyMofo24]

Ok I know this idea is crazy...and didn't give it much thought to it when I posted it...I forgot about having to power them...only reason for doing this is to give it a little more bass for the time being. What about taking the jumpers off both the 7's and the 10's run the mids/highs of the 7's through my amp. Then run bottom posts the bass through my receiver?

Don't use the RTi10, they won't have near enough bass for this type a job.
As for the rti4, Hell yeah go for it. Don't mind the others, they're gutless! :D

[audiobliss]

^^Yeah, do it. Then post a pic of the look on your face when the RTi4's mid driver shoots across the room and lands in your lap! :p

Bi-amping the speaker isn't going to change the speaker's native frequency response.

Why don't you use your Rti10s? Their -3db is 35hz, compared to the the 7s, which are 53hz.

Do you even have an rti4? It's not listed in your sig

[aaharvel]

Krazy, Rti4. Do it.

DO IT!

[KrazyMofo24]

Well I hooked up the 10 and the 7's its working fine...gonna do the left's.

I havent done any listening to see if it actually does indeed sound better. But its working like I wanted to...I know a sub is the answer i'm not trying to get around that I just wanted too add more bass until I buy one.

[KrazyMofo24]

I dont want the 10's cuz their mids/highs don't come close to the Lsi's. I have the Rti4's on the floor not used which is why their not on my sig.

The rti4 likes to participate in group activities. Seems unfair to leave it out due to it's size. I attribute it to picking team mates on the playground.

Use the 4 for your sub. Let it participate.

[KrazyMofo24]

Ok after listening to it...its not using the Lsi7's driver...sounds like crap this was a waste of one hour. :)

[audiobliss]

Gee, I wonder if we'll listen to the consensus next time. ;)

[PaintballFREAK]

lol true

[KrazyMofo24]

Well when I put the jumpers back on the Lsi7's first and I noticed the Rti10's stopped using its 6.5 Driver and just played low freq. The 7's are playing normal but the 10's are adding more bass sounds better for now.

[brijenjas]

^^Yeah, do it. Then post a pic of the look on your face when the RTi4's mid driver shoots across the room and lands in your lap! :p

Thanks, the image of that happening is just too funny, almost spit my drink out laughing.:o

[Toxis]

I don't know what's worse... that these ideas came up or that no one wants to take the time to explain WHY it won't work other than just laughing.

BTW, I want my car to be faster so I thought about taking off the transmission. It seems to be heavy so this should work...

[KrazyMofo24]

Lighten up tough guy just because an old fart like you can't possibly think of a bad idea every now and then. It wasn't that big of a deal. Is this one your pointless responses to get your post count up?

LOL Man that's harsh. Now I thought, I, was the one that was supposed to talk a lot and mostly out of my ass, but this guy here takes the cake on strange and peculiar ideas. I dont think I would have thought of using a single driver bookshelf speaker as a sub.

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?

[KrazyMofo24]

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.

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?

[mrbigbluelight]

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.

I thought you were the LSi7s in the same setup JACKASS, thats why I asked.

[Andrew2112]

I say use the RTI4 as a sub, listen for a couple of days and then report back...

[VR3]

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."

[KrazyMofo24]

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.

[Toxis]

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?

[jdhdiggs]

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...

[AndyGwis]

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 :)

I think that thing is damn interesting. Could it possibly work?

[VR3]

Thats an amazing speaker there Reaper...

And the design behind it is phenominal... I bet its bass response is insanely tight and punchy..

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.

If you do make it look a little more badass. That thing is ugly as sin as show in those pictures.

[VR3]

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...

[DaveMuell]

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?

[VR3]

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...

[VR3]

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...

[DaveMuell]

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...

[Shizelbs]

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.

Yea, you really should be using the LSi7 for your sub rather than the RTi4. For a while I had some old BOSE cubes hooked up to my headphone jack that put out some decent bass, but finally went to the RTi4 (since they are matched to my Rti70's of course)as my sub and now I am WAY hooked up with bass.

[Shizelbs]

See! Didn't that make a huge difference?

[KrazyMofo24]

I got a sub now...so we can move on.

[ronnie]

what sub did you go with....i dont see it in your signature??...

[KrazyMofo24]

I got a Yamaha YST-SW315 from Suckstobeme...its not an SVS but its getting the job done. I like makes realize how much I was missing without a sub.

[ronnie]

its actually a decent sub....my buddy has one and its pretty accurate...i never heard an svs, would like to, but there subs seem to be the king around here

Don't feel so bad for being a newb. Some of the questions I asked a few years ago on the speaker building sites, when read now, embarrass me to death. We all start somewhere, so don't feel ashamed, newb :D

Thats actually true. I feel the same way about my early posts. My recent ones aren't much better though.
