I am looking for input on this sub. I have looked at putting one in for some time but i haven't ever heard one or talked to some one who has one. What can you guys tell me. Is it just an SPL sub?? I would be putting it on a MS2250

Post by **Bfowler** » Wed Nov 05, 2008 6:54 pm

it might want a little more then the 2250.

its VERY loud, VERY low extension. with adequate power, its tight and wonderful.

the down side is it is VERY inefficient, and weights quite a bit.

as far as sound is concerned, its damn near perfect. its the install side that makes is hard to deal with

It's a monster SQ sub... and it's very power hungry. A pair of MS2250's would be a better match.

Keep in mind it's a dual 4 ohm woofer (some say closer to 3 ohms), so if you ran it in parallel (1.5-2 ohms) you would be running well below the MS2250's rated bridged impedance (4 ohms). This means you would need some sort of fan shroud to keep the amp stable, otherwise it may cut out or could even be damaged. Fortunately the TA's take lower impedances better than the original 2250's... those required a shroud just to run at 4 ohms bridged

If you haven't bought the sub yet, I recommend the RSD comp instead. It's far less power hungry, and does a lot more with the power that you give it. Also, it's available as a D2, so you can run it at 4 ohms bridged with ease (or a pair of D4's).

wow factor = elite. Get a bigger amp

how difficult is it to use 2 ms2250 on the one sub. other them matching the gains what about the time alignment of the signal to both amps? or what single amp would you suggest

Post by **mhyde71** » Wed Nov 05, 2008 10:04 pm

never can use 2 amps on one sub.. unless they are linkable, w/ a net result of a bridged signal...

I would not suggest running two amps on any given one (1) sub, i.e. putting one amp on one voice coil and another amp on the other.. that is urban legend if you ask me, the coils NEED to run in sync/unison, not with separate signals.. (i.e. left / right.. ) not in my book anyways.. maybe someone can correct me.. I mean given that the sub freq's tend to be mono, maybe it's conceivable, but in no way would it be reccomended...

I am running two RSD 1200.1's to a 15'' right now. All I did was split the signal from the Basscube and ran equal rca voltage to each amp( i think 10 volts). i then measure 61.1 volts AC from the 1200.1's terminals and this thing pounds! I am pretty sure I got it all right because running the kind of juice I run I dont think the sub would of lasted , it does sound wonderful though.

As long as you have the same signal(mono) going to each coil you will be fine , along with gain matching of course

Post by **mhyde71** » Thu Nov 06, 2008 2:29 am

yeah, I will go for that... i.e. providing you can 1) be certain you have the exact, and I mean exact signal going to each coil... that would be the only way... but still I would be concerned that perhaps the outs are not balanced, right gets/just hits a slight bit harder than the left.. but if you know what you're doing and stuff with measuring the signal, and all that.. maybe.. But I wouldn't, that's just me..
I think/feel I would be concerned of even hitting the balance one way or the other too much by accident... right???

wouldnt that really jam up a sub, if you are throwing 42 volts in to one VC and 27 into the other?? or does it not matter as long as it is the very exact same signal/freq?? and once there are differences in the signal freq that it would start to work against each other.. I dunnoo.. I still wouldnt fool with it as it sounds that there has to be just so much just exact and would br concerned about any slight varible that comes down the pike and jams it (the sub) somehow... but interesting subject...

Nah... that's not right.

As long as both amps are the same type, get the same signal and are gain matched, there should be no issue running one amp per voicecoil. Any minute difference in the signal will be averaged out through the magnetic forces within the speaker.

It's not like you would be running the right signal to one amp and the left signal to another. This is the wrong way to do it. You would either need a mono signal, or you would have to have both L/R and let the amp do the summing. Basically you put the inputs into one amp, then take the AUX-OUT and put it in the second one... then gain match the two amps and away you go!

right so it can be done, but there are some specific pre-requisites that have to be taken into consideration.. not something you can simply throw two amps and flip the bridge switch and run to the respective coils..

That I certainly understand... but for me, I dont think I would be inclined to do that...
What are the benefits of doing that??? versus getting a single amp with matching power?? would there be a situation in which one would want to control single coils, or any advantages to having two amps versus just one??

interesting topic I must admit... but running separate signals to coils in that fashion scares me.

and that's kinda what I had envisiond when it was brought up...

Well, it actually IS that simple. You run RCAs to amp 1, and aux-out to amp 2 (or use a y-splitter, whatever you want). Set the gains of both amps with a DMM (you should be doing this anyways), and blammo! You're done!

Benefits? More power. A single 2000 watt amp or two 1000 watt amps would be the same amount of power... BUT he already has two 2250's.

A single 2250 would give the Elite 12D what I consider the bare minimum power, and it would be at the wrong impedance too. So, two 2250's is a way better option in this case. Or he could scrap the 2250's altogether and run a generic 2000 watt 2 ohm optimized class-D. Either way is fine...

It's not rocket surgery dude.

Matt ,

There are a couple of reasons why I chose to run 2 amps to one sub. One reason is because I am running a quad 2 ohm sub which has 4 coils and is basically very hard to wire but has many wiring options. And because I am running just one of these quad 2 ohm finding a amp that would run 2000 watts at a 2 ohm load was a little tough for me consodering I wanted to try using the PG amps. Previously i ran a High Current amp by Audiobahn that was stable down to 1 ohm but the problem was I couldnt wire this quad sub to 1 ohm and to take advantage of the Audiobahn amp I would have to either run it @ 0.5 o0hms and basically run 3000 watts to a 2000 watt speaker and burn out my electrical system or run a pair of coils of of each channel of this Audiobahn 2 channel amp(which i did) but I was only getting 1600 watts rms or 800 watts @ 1 0hm per pair of coils

So i said lets take advantage of the RSD 1200.1's and use that cleaner power that my electrical system can support. So now I am guessign I am running close to 2000 rms or 1850 rms to this 15 '' at a 4 ohm load on each RSD 1200.1. So the end result is a clean sounding ball shaking sub that I can proudly say is ran with the power od Phoenix Gold.

Stipud: I was going to run some rca's from the aux of amp #1 but I deciided to just let the Basscube take care of this signal and run seperate off of the basscube. Is this okay? Both channels from the basscube are mono I think because my non-fader is mono and they are on mono amps.

Is this cool?

Sounds good now i just have to come up with $330 for the sub. Any one here know a good person that rebuilds alternators (for a Pontiac Aztek) to a higher output. I cant find a reliable shop around here.

Any one know if PG still services the Ti12E?

What amperage of alternator are you looking for?

Not ssure if they arstill service it but my guess would be yes

See what Wrangler NW can do for you... they make the best HO alternators I know of. They used to make PG's alternators as well

If it's mono, no problemo.

as much as the housing will accommodate I had a 220A Ohio Generator in my XR7 and never had a problem so i hope i can get it around 200a +/-10%

What would the best amp to run two Ti Elite subs...Ti 1200.1 x1 or x2, Ti 800.1 x1 or x2???

I'm on the verge of bying 2 Ti Elite subs and presently own 2 Reactor amps...knowing these are not powerfull enought to run the subs was curious to see what would be the best between a Ti 1200.1 and T 800.1 or either would do the job.

Post by **stipud** » Fri Nov 07, 2008 7:43 am

Ti1200.1's and Ti800.1's are optimized for 2 ohms. Running a pair per sub won't gain you lots of power, because you would be running them at 4 ohms. A single Ti1200.1 for each Elite will be a great match.

cojones · Post by **cojones** » Fri Nov 07, 2008 2:47 pm

Your gonna pull some extra power out of the Ti1200.1 anyway because the Elite is dual 3 ohm coils. That should deal with the power lost in moving that monster. Plus the Ti1200.1 usualy does 1400+ @ 2ohms.
