neodymium speakers

I know the speaker is louder but how much louder? I want to put a celestion g12 century vintage in a blues jr for a portable practice amp. the amp is rated at 15 watts but I thought it might be nice to bring it to a little jazz jam session once in a wile and I want enough clean head room to be heard over a drummer and a hammond b3 organ player. I want to chuck the stock eminance speaker and friends suggested this speaker for more clean headroom from that smaller amp platform. I dont want to haul a bigger amp in there if I dont have too. I intend to elevate it off the floor so its got half a chance to be heard by the other players.
 
Re: neodymium speakers

Phil, I don't know much, but I one contacted Eminence about their Neos, and the main man there, Anthony , wrote me back and told me its mainly a question of weight savings, and not too much about sound, at least for their speakers that are designed to have the exact same tone, but with ceramic and Neodymium magnets as an option , and thats what you are paying the big bucks for, is the weight savings , and not any real outstanding tone difference.... but then Celestions 'Dr. Decible' told me , via e-mail, in response to my question about neodymium speakers , that their 'Neos' had a great deal of touch sensitivity, more so than other non Neodymium Celestions.
Thats all i got. Hope it helps.

I plan to try neos

your speaker in question is 98db http://celestion.com/product/14/g12_century_vintage/ so I would compare it to db which is exponential really, so a change of 3db will be huge

based on what I have read and people's comments on this forum I want to get a laney cub 12 and eminence tonkerlite, and that will give me tube sound combo and weigh about 20 pounds! http://www.laney.co.uk/products/product_details/27
 
Re: neodymium speakers

right on, I was thinking by swapping out the the speaker and trani I could squeeze alittle more headroom say....in the range of 20 to 25 watts out of that amp. Fargen makes a mod where you can create an extension speaker for this amp but I dont know how much the mod is and I dont want to spend 1,000 dollars extra on this amp. would be cool to put an extension cab below it both speakers celestion neo"s for nice ambiance in a small package
 
Re: neodymium speakers

How much louder is easy to figure out but we need to know what the stock Eminence is...

The G12 Century is rated at 98 db.

If the stock speaker is around 98 db the Celestion will be about the same volume if the stock speaker is 96db you'll notice extra volume and if the stock speaker is 100 db you'll actually loose volume.

All that said I'm guessing that the stock speaker is in the ballpark of 98 db as that is a fairly typical number.

Now, if you want to take a 15 watt practice amp and use it at gigs go with a mega LOUD speaker...

The Eminence Tonker Lite or Lil Texas are both also Neo speakers so they are light weight and they are both 101db...the difference between a stock 96-98db speaker and a 101db speaker is quite a difference.

Email Eminence and tell them the numbers on your stock speaker and they can tell you the db rating of that speaker...
 
Re: neodymium speakers

You are doing exactly what I did about 3 years ago.

I have an amp that I LOVE, but it's "only" 2 Watts. I upped the effective wattage by finding the most efficient speakers I could that I like the sound of. In the end, I settled on Eminence Wizard/Swamp Thang.
 
Re: neodymium speakers

So get this, a vintage 30 is 100db while the celestion neodymium century is 98db. So the v30 8s actually louder then the neodymium speaker in the blues jr. Thats weird to me that the neodymium speaker is less loud then the v30 according to celestions websight info

Re: neodymium speakers

It might be weird, but in general they are engineering them for a sound and not so much for power. Yes, they could go over the top and use all that neodium potential power and produce a speaker rated at 120 dB or something, yet no one would buy it, because with the current state of the art in guitar speakers, that speaker would sound horrible! You would have to change a lot in speaker design to be able to rightly use all that power and right now they have started with the neo's by going for a good sound and light weight, that is enough selling point to them. Most amps are loud enough already anyway ;).

Say what is that 2 watt amp you are referring to that sounds good with a Wizard and Swamp thing? I assume you are doing a 2x12 with the amp. Does this produce a goodly amount of volume? . . intrigued!
 
Re: neodymium speakers

I always thought neos were more about light weight than super high efficiency.
 
Re: neodymium speakers

I've had a G12 Century Vintage for some years now. Good definition but it's also a very bright speaker. Overly bright for my taste. I wish I had done a little more research before I bought it because a lot of the reviews I've read since reflect that same sentiment. I think it could be a good choice for overdrive and distortion and would definitely help you cut through the mix. However, it also sounds best in a closed back cabinet. For clean tone in an open back I found it to be to "ice picky". Have you checked out any of the Eminence and Jensen offerings?

Phil.
Do you want neo to save weight, or just to make you amp louder? The main reason people choose neo is because of the weight saving. A Blues junior with a regular speaker (even a pretty heavy one) is still a light amp to carry.

If its the latter then there are a wide range of speakers out there that will do the job. If its volume you are after, its max sound pressure levels you should be looking for (measured in db). When speakers are measured, the standard is 1 watt of power measured at 1 meter with a decibel meter over the entire frequency spectrum. Whatever frequency displays the highest db will give you the spl rating. Some speakers have their peak fairly high in the sonic spectrum which will give you a bright and cutting speaker (one that might sound like it will slice your head off), but not one that necessarily feels fat and powerful. Another speaker might have a slightly lower spl rating, but its peak is in a different part of the eq spectrum and might feel like it has more "punch". Different speakers all have different feel in that respect, so purely looking at spl ratings does not tell you the whole story. The sound, feel and overall performance of a speaker is something you can get clues about from spec sheets, but in the end you have to try them out yourself.


I'd steer clear of a vintage 30 for your purposes. Its loud yes. Its very clear and cutting too, but that is more of a rock thing than a jazz thing for bladting through the mix nest to a heavy handed drummer and a an electric bassist.

If you want your BJ to be a bit louder than currently and sound good for jazz, then go for a cannabis rex. Its not neodymium of course, so you wont get a weight saving, but it is a very efficient speaker (over 100db) and it will do the job of not only making your BJ appreciably louder, but it will fatten up the low end and give a nice full fat tone (something blues juniors are not known for).

+1 Good advice. You obviously know your speakers. That was exactly the problem I had with the G12 Century Vintage. Although it was clean, defined, and cutting it "sliced my head off". I'm now running a C-Rex in my SCXD extension cab that has increased the volume a fair amount and a pair of C-Rex in my Mesa and extension cab that have tamed down my Tele considerably.
