Thank you, Mr. Widget for pointing out that the newer JBL Blue is darker than the original version blue used by JBL. According to some of our long-time LHS forum members, the universal color chart...
I stumbled upon this on the Harman Pro website today 3/17/2024: https://help.harmanpro.com/4435-blue-baffle-paint "4435 Blue Baffle Paint The paint a custom mix. The vendor is: Naylor's Paint ...
I own two MP418SP, and the amp is basically a Crown CE2000 with a novel crossover that makes it a very versatile unit, if not heavy as you well know. The box is rather small, and the tuning is set...
You need to provide a 2nd order peaking high-pass filter with a Q=2 tuned to 25Hz to get the 4645B to do its magic. The 4645B, with its' two 5.25" diameter x ~24" long port tubes, is tuned to...
I know this is an old thread, but...
I'm just beginning a HT project that based the JBL AE Series AC2212/95 that uses the same drivers and horn with a much better crossover.
I love the tiny...
Earl, thanks for pisting the picture!
Makes perfect sense... An ultra long excursion subwoofer would benefit from the vents to relieve the pressure & vacuum built up between The Spider and the top...
I saw the poss about Guido's reconing 2227 into ME150H
What frames am I thinking of that I've seen with the side vents near the magnet and under the spider?
What is the core of the ME150H?
I'm guessing it's the 2227 / 2242 motor...
I'm hoping it's the 2227 basket, as I have 3 2227H that need to be reconed
1audiohack once showed me a 15 in high-end...
Well said, Mr. Widget!
Yup. Your two ears.
God gave you the best measuring equipment known to man - and the ONLY two that really count.
And, the brain that they are connected to...:p
Grumpy, you are 100% correct: charge-coupled capacitors reduce the crossover circuit distortion AND push the behavior anomalies of the capacitors to a level equating to a peak of 2 1/2 to 20 watts...

They were:
Betty Butt
Bella Butt
and
Beth-Sheeba Butt!!!
...they called it the Bertha Butt Boogie...
No question!
Glued-on wedges is the factory method of attachment. :yes: The exploded diagram doesn't reveal this detail, as the 2405 horn is an assembled part.
The outer horn is actually an 075/2402 machined...
There are some Compact Monitor Systems (CMS Brand) 3-way monitors for sale on the bay right now. The seller states that the 2450CF (F? Typo?) are special-built for CMS by JBL, and that they can be...
OK... but you need to re-read my post and keep in mind that you're not in a production company or service situation where you have to get the amp in and out of service and back on the road on the...
I feel your pain... however, considering their age, the nickel plating hasn't done too poorly, has it?
I'd guess it is tin plated instead of nickel but I :dont-know:
If you have the gold...
On low-voltage contact points, oxidation can produce a "diode effect" that can make for a nasty sound quality due to the fact that the oxidized surface is resistant to current flow below a certain...
Crest Audio was started by former BGW employees, and a brought a lot of the same thinking into their amp designs, like their 'overbuilt' power supplies.
Your suggestions really apply to all cable...
:wtf:Why don't you use the mic with the DriveRack's built-in 1/3-octave measurement graph function?
That's what it's made for!!!
This ain't rocket science, but it might take all of 5 minutes...
This ain't rocket science...
Ever heard of cardboard spacer gaskets? They're made for ALL sizes of speakers, ~1/4" to 3/4" thick, have relief notches for bolt holes, cut into 4 pieces with a...
Thanks Mitch.
I posted this thread 4 years ago while helping a customer with butchered-up SRX715's restore them to order. At the time he elected to save $200 with used 2432H instead of used 2431H....
2435H is a whole other animal... no comparison there.
Certainly no comparison to ANY 2" drivers...
Don wanted to know cone weight, etc. to compare to recone parts from McKenzie et.al.
Oddly, both of my JBL C8R2226 kits complete with dust caps weigh 102.5g
The official JBL T/S Parameters...
