desecration of the GS112

First off, I love my GS112s. Recently one of them developed a 'rattling' sound. Others in the band thought it was a 'growl'. Uh-uh. It had little to do with power or volume...it was just there, and got inside my head. I pulled the speaker and checked out the 'usual' culprits-surround, spider, voice coil...all were A-0-K. The speaker did it's rattle, in, or out of the cabinet. To me, it has to be something loose under the dust cap. I have spare GS112s, so I soldiered on.
When I originally purchased my cabs, I inquired out of curiosity, the cost of replacement drivers. I thought it was most reasonable. Well I called the dealer from whom I had purchased the cabs...the figure I got was more than twice the earlier quote...not to mention they were not in stock and I would need to pay for shipping! Obviously, the first quote was mistakenly given...it had to be dealer net.

Attn: newcomers: I am a cheap bastidge!

As the OEM speaker is a custom Eminence, and I have contacts there, I got some info on the speaker. No, they couldn't sell me one...I didn't even ask. But I was given the names of two speakers that were "very close" to the OEM driver.

One of them was the Deltalite II 2512. I had been watching the neos as they have evolved and was very curious. On a lark, I ordered a pair. Put one in last night and played ad nauseum...comparing the OEM to the Deltalite. Summoned the wife for her input. We both think we have a better speaker here. The neo went noticeably lower, using Dave's "let's play with your ThunderFunk" suggestion of boosting the lowest band of the semi-parametric and see how low your cab goes...
With the OEM driver, it came alive between 40-45 hz...right where the OEM spec of 42 hz said it should. The neo, tho' was really coming alive between 35 and 40 hz (yeah, I know...I wanted it to happen...but at least I used the same knob, so there is a relative correlation there...if Dave's markings are really that accurate...man, that's spooky!)
The neo was noticeably louder at the same input levels. Not 'blow you away" louder...but not subtley, either.
Perhaps the greatest difference, to me, was in the mids. I knew that the GS112s were 'scooped' in the mids when I bought them. I don't mind that at all. I could eq around that, either with my F-1X or TF. The neos are so MUCH more articulate in the midrange. The last two cab series I have been using have both been 'scooped' in the mids. I have been used to boosting my mids a touch on the bass itself. This helped restore the 'cut' in a band mix.
I haven't broken out the F-1X yet, but my trials with the TF have led me into heretofore uncharted territory. While the 'enhance' knob sounded good in a solo environment, I couldn't use it at all in a band context...cutting the mids was a no-no. Similarly, rolling the timbre to the left was great for 'thud' but definition went bye-bye.
This is now a whole new ballgame. The mids that the neos bring to the table now allow me to experiment more with the TF. Settings that had been 'taboo' on stage now are viable. I can tweak the 'enhance', roll the timbre to the 'dark side'...all while being able to cut through.
There 'may' be a caveat...the neos aren't rated for the same power as the OEM speaker. It's close...300 for the OEM, 250 for the neo. These are both rms ratings..."music program" numbers are doubled...since this is where we 'really' operate, it should be a moot point.

My wife and I, both, after 'ad nauseum' listening...gave the nod to the neos...by a huge margin in 'real world' terms.

My disclaimer:

Please do not 'desecrate' your lovely GS112 cabinets. They are wonderful, just as Aguilar has provided them. (really!)

If you trash a driver...and are the experimenting type...try the Deltalite II 2512.

At the very least...it's 7 lbs lighter!

It was the Delta 12LF...actually, if I were a wagerin' man...I'd bet a year's wages that the Aggie speaker is nothing more than the Delta 12LF in the Delta Pro cast basket. All of the numbers (and my observation) lead in that general direciton.
Interesting, as the DLII2512 and D12LF are very different drivers. What appears to be a DPro frame in the OEM is more likely a Gamma Pro, long ago discontinued for retail sale but they are still used in many OEM applications. The superiority of the 2512 is no surprise, OEM drivers tend to be on the lower end of the quality scale. When better drivers like the 2512 are used in OEM the manufacturer will usually advertise the fact.

or they'll just say the speakers were designed with their sound in mind. ;)

eminence does make some terrific speakers, and i'm a HUGE fan of their guitar line, but aguilar also makes a terrific 1x12 cab, and it'd be a shame for a perfectly good cab to be ruined for curiousity's sake.

still, glad you were able to find a great sound despite the tragedy that befell your original speakers. :cool:

Absolutely...and my point as well-"Kids, don't try this at home.";) . Had my speaker not taken on its new, 'unique' voicing, I would never have thought to change it out-I love my Aggies!!. I have a lifelong aversion to buying items at the "sucker price" just for the sake of convenience-I really cannot afford to. Not going to mention the price I was quoted for replacement of the Aggie speaker-just let us say it was 'up there'...to the point that value, to me, had exited the equation. I was able to get both of the 2512s for less than the single OEM speaker would have cost me, simply because of difference in distribution channels. I had already dealt with Eminence's tech folks when trying to match competitor's drivers in other applications...they were very helpful...and I was extremely pleased with the results each time. So I had faith in their giving me the straight story...and for telling me when I was in 'uncharted territory'. Really a wonderful company.
I already had an 'escape plan' devised...if the 2512s were even slightly off the mark, soundwise, I would drop them in some spare floor monitors and, biting the bullet, order the OEM speaker. It would have been an experiment that failed. No biggie-I could use the extra speakers anyway. Did I mention that I love my Aggies? I would never, intentionally, let any harm befall them :bawl:

Bill, thanks for weighing in-I hoped you would. Also thanks for not openly calling me a nutcase here on the forum :D

Remember the 'Special Design' stickers on the back of Fender guitar drivers? The only thing special about them was the sticker. Leo did have a preference for certain Jensen models, but when it came time for him to sign the check it was always made out to the company that gave him the best deal.
 
I am fascinated by this thread because I am one who has to always be upgrading everything I own. I just upgraded my dual monitor card and added a gig of ram to my pc. Getting new tires for one of my vehicles is always a research project.

The Aggie upgrade sound very interesting but has also made me look at a different path on my second cab. I was planning to purchase a Epifani UL110 not just for a second cab but to replace my Workingman 10. The LMII and a UL110 together weigh 4 lbs less than the workingman. But what I am know considering is changing the speakers on my Tech Soundsystems CT212 to the DeltaLites. (for those who have not seen one, it is a German Cab very like a Schroeder configuration) I was thinking of selling it because of it weight which is 58 lbs. But putting in Deltalites would make it only 2 lbs heavier than the Aggie. At 58 lbs the cab was starting to feel a little heavy after all this downsizing that I have bee doing.

As usual fun reading all of your responses and it is great to have Bill Fitzmaurice add his wisdom to a thread like this...:D
 
Probably a stupid question but, I assume that after changing the speaker that the rattle is gone? One of my GS112's had a rattle that I traced down to the spring loaded handle vibrating. Dave from Aguilar saw my post about this and sent me a new handle. After installing it the rattle seemed to go awayuntil my next gig. Then it started up again. I remedy this by putting a spare guitar cable under the handle. Problem solved, plus I have a cable handy in case my wireless suddenly has a dead battery. Funny thing, my GS112NT's never had this problem. only the tweetered version.

No, it's not a stupid question. When I got my first pair of GS112s...I had the handle rattle...Aguilar said it would go away and it did after a few times gigging the cab. This 'rattle' was the speaker itself. It did it both inside the cabinet and hooked up all by itself on the floor. I could find nothing visibly wrong in the areas that usually cause similar sounds...the surround's glue joint was solid without voids as was the same joint on the spider. The voice coil was not rubbing throughout its travel. It appeared that the tinned leads had 'wallowed' out the holes where they pass through the cone slightly, so I re-glued them, but the rattle persisted. My only thought at this point is that the leads may be loose underneath the dust cap.
Changing the speaker...I had also substituted the speaker from another one of my GS112s earlier...confirmed the problem was the speaker itself.
