hi.
i wanted to share my outcome of my 4345 project with you.
still waiting for the 2122h to arrive (hopefully tomorrow)
used drivers:
2405 (original blue dia + alnico)
2425j (original dia)
2307 + 2308
2122h (until now test with 2123h)
2245h (original cones)
i used the giskard schematic with biamp only and coupled caps.
external crossover in external box.
here are the photos:

Are you happy with the sound? What crossover are you using for the bass amp?
for now i am happy.Originally Posted by lordoflight
have to wait for the original midbass chassis to come. i will have to do measurements once all the original drivers are built in.
but i am impressed with the moment outcome too. knowing it will be better with the 2122h...
i am using a active crossover for the LF drivers with the JBL 6260 for now (crossing at 290 Hz). no passive crossover used.
for the moment i am using an mini dsp DDRC24. but i will go back with an analog active crossover in the future.
my budget for now is low due to the high costs of this project...
I know the feeling. I have started my own project last year and still not done with it.

My filters are now in Australia with Mr. Ian MacKenzie for a full revamp to 4344MKII. I was not happy with the sound. To me it sounded veiled and was lacking bass. Maybe bi-amping will do the trick. What can I say... this is one hell of a hobby....
hi.
i already have it biamped. LF has no passive crossover.
i like the sound so far.
this hobby is real fun. sometimes it can be frustrating but when you get it right in the end, you smile like a child on christmas eve..
the only thing that makes me thinking is, that the L-pads are only to the half way "sensitive". after the half the behaviour stays the same.
means, that from the half there is no difference in volume any more until full turn...
can somebody help me with that?
is that normal behaviour?
thx
It is difficult to tune in the l-pads by ear. When I was tuning the l-pads I was using a dB meter. Nevertheless when the l-pad is full off the speaker should be almost silent. Is this the case?
hi.
yes, if i turn total to the left, the speakers are silent.
Nice Work!
You should buy yourself a Dayton mic https://www.amazon.com/Dayton-Audio-.../dp/B00ADR2B84 attachit to your iphone, geta db meter app and you're in business. Fix the mic in front of the driver you want to set and get the measurements going.
Refer to this thread :http://www.audioheritage.org/vbullet...l=1#post391167
I hope this helps.
i have a umik-1 microphone with my minidsp.
i will do the test once the 2122h is mounted. they arrived today. i am happy now!
will update you soon.
thx
Where did you find the 2122? I ended up using 2123 instead?
Mine use 2123 baskets with 2122 cones from JBL. Don't know if any 2122 cone kits still exist though.
GT's note in the Designer's Post in the System Information archive says:I noticed a comment earlier in this string regarding the 2122H. It is a really good voice transducer. It always has been and always will be. Things just sound really natural through it. Another one that might be slightly better is the 2123. It is a little less smooth but perhaps a little more realistic on voice. Either are really good for that critical range from a few hundred Hz to about 1500 Hz.
". . . as you have no doubt noticed, no one told the 4345 that it can't work correctly so it does anyway."—Greg Timbers
i know one who knows one who had them. was just lucky...
i have two original c8r2122 recone in spare.
was lucky to get them. wanted to recone e-110 but then i got the 2122h.
