Testing JMLC 270 :)

Thanks for input Earl :)
Will take a look!
Yes, do also think Seas just don`t want to be involved.
Can understand that.
I have done a lot of thinking how to fix.
The biggest issue I think is getting it back together and get the gap...
Got answer from Seas.
They can not help :(
Seems like reconingspeakers still have recone kits from GPA.

No problem! :)
Maybe it will be repaired som day!
Just.....

Thanks for your input Earl! :)
I have just sent an email to Seas if they can help.
I can not ask GPA to pay for this, I don`t now how it has been broken.
I just bought four 515 cheap and hoped...
Maybe somebody nows if magnet from other Altec will fit mine 515 LF?
Like the 3156, 421 or 515 GHP?
For the record :)
These are not a new buy from Great Plains Audio, they are some years old, but not been used.
So no warranty or anything.
I have 3 that is ok, it`s just the last one with...
Hello all! :)
I have one GPA 515 LF 16ohm (Ferrite magnet) where the backplate and following polepiece has come loose.
The driver has probably been dropped to the floor some time...
So I am...
Sorry, my mistake :)
I have just been lookin at Qms=2,5 on 2225 and thought it came from alu former.
Actually one of mine E140 was probably reconed with 2225, it had longer VC then E140, and it had...
Yes, one pair of each: 2220, 2227, E140 and GPA 515.
No I have not tried one pair alone.
Can`t really tell any big difference between them, except the 2220 is the most efficient.
The easiest to...
Correct, the boxes are tuned to 28hz, so extra bass adjusted in DEQX.
Yes, the 5ohm resistor takes down the voltage sensitivity on the E140 (8ohm) so it`s more comparable to the 515 (16ohm).
Have...
Thanks :)
It is the GPA 515 LF 16ohm with ferrite magnet.
No, I have note retuned in any way, I just changed setting in DEQX DSP.
E140 is 8ohm, but putting 5ohm resistor in series with it...
Well..
Got som GPA 515 LF :)
So E140 on top and GPA 515 in the lower boxes.

Glad you like the setup! :)
I`m happy with it and play a lot of music!
Oh! So you have the 2205! Thats nice!
The specs are not far from mine E140.
I actually looked for 2205 recone kit to put...
Thank`s :)
The alu dustcap maybe has some kind of ringing very high in frequency?
I use the bass up to 600hz, so don`t think there is any difference with the paper black dustcap.
E140 is...
Reconed a pair of E140.
Used black gaskets and black dustcap.
Playing with them now :)

One of the 2405 got broken :(
So bought a pair of JMLC 1400 and Celestion CDX1-1430 as backward ambient tweeters.
Also have done som work with DEQX and got a nice crossover at 500hz between...
Could probably go a little lower with the crossover yes. :)
I have not measured how loud....
Loud enough :)
For the bass yes could go with drivers with higher mms.
As I say, it`s not that...
The Frequency response.

The simulations ar not all correct, but maybe gives an image on what`s going on.
For the driver I just used som data on JBL 2440 found on diyaudio.
Think the 2227 was mostly sold in the european market?
They do sound nice.
Both 2220 and 2227 being more like midbass drivers, they do need some EQ to play bass.
Their short stroke specs I do...
Thanks Widget :)
If you think of heavy music with bad recordings it is as good as it gets.
But in general heavy music sound really good in big horn speakers as they have attack and dynamics.

Changed for JBL 2220 in upper and 2227 i lower box.
Testing 2405 tweeters playing backwards.
Sounds good enough for playing Black Metal... :)
