Discussions on building or modifying custom systems using JBL, Altec or LMCo components
JBL's official stance on purchasing transducers through JBL Consumer and HPAV Dealers or Service Centers is as follows as of January 2010: We only provide parts for our finished units that need repair. Customers will need to provide model and serial numbers of Harman products they are...
What follows is an attempt at a step-by-step photo and caption Thread for resurrounding a JBL low-frequency transducer. I thought I'd compile this since I was doing a pair, and it might be of interest. Every resurround I have done is just a bit different – got it’s own unique issues. The...
Does anyone have frequency response measurements on the ALTEC 802G or 808-8Bs /511B combination without the M19 XO, Radian or GPA diaps? I am trying to equalize this combination using a active EQ (no simple CD compensation) but I am having difficulties finding such measurements. Almost everything I...
Hi Folks, this is my latest offering to the JBL Gods ....... Still a few things tweak ,but I want to get the parts in and fire them up . I'm not convinced by the colour nor am I happy with the way the top looks from the front . At the moment a 2 way with a tricked out 2234 and 2435 on...

Hi Guys and Gals. First time posting on this forum. I am rebuilding/restoring a pair of 4350B JBL for a client. He wants to veneer case work in Ebony Macasar and possibly the front as well (may be in fiddle back maple) No question, they will look fantastic after I am done, but in this case whats...
I just typed a very long post and lost it:banghead: OK, here we go again. This is my first post here. I heard about this forum over at the Klipsch forums. My first real speakers were JBL L60T's that I bought new in 1989 and just sold last year. I really wanted L100T's but could not afford...
Can't call it a clone, really, 'cause it doesn't exist. 2262HPL + 2432H on PT-F95HF in Dayton KD Trapezoid kit cab from Parts Express:
I have an opportunity to purchase a pair of brand new Truextent Beryllium Diaphragm - 16 ohm for approximately $1050 (approximately $150 from current list price). I will be using these in a pair of JBL 2441 drivers I currently have. As you all know, I am in the process of constructing a JBL...
I have a couple of D-131s and 1217-1290s, and N1200 crossovers. I would like to build a cabinet for them. Was there actually a speaker containing this ensemble? Or a JBL approved cabinet plan? :confused: TIA
My next project is to build a 80-400 Hz front loaded horn for HiFi use. After a lot of reading I have realized that the JBL transducers I have (e145, 2226h, 2205a) are not optimal for this. There are better drivers. I have been thinking 15", but maybe 12" is a good option? 2227h: EBP 182, BL 23,...
Merry cristhmas to everyone. All you people with horn system can´t you post some pictures to look at now when it´s dark and cold. Regards mats
Following recent prolific musings over E2 inspired ideas in the E2 clone thread I have elected to open a new thread on my own project. I welcome on lookers and feedback but please refrain from splashing Monet's palette or Rolf Harris's 6 inch brush with subject matter that is just not relevant....
Vertically asymmetric (20° + 30° x 90°) "Second-generation Optimized Aperture™" mega-PT ("Progressive Transition™") waveguide, 30" W x 15" H, available in both 1" 2374 (126-00177-00) thread-on and 1.5" 2384 (126-00177-01) bolt-on throat variants:
when I got the 18Ti's as donors for backups for the 250ti's , one of the 044ti's was dented. My JBL friend who says he's fixed many Ti tweets and I pulled the driver ....to push out from inside , BUT can't get off the wood/masonite cover...can get a blade around underneath , staying clear of the...
Yet another one of these "4345" threads. :cool: I'm reposting this because I was asked to. I decided to whip up a pair of DIY 4345's this past spring. I could post a bunch of reasons along with a ton of detail but I really need to get back to more pressing tasks at hand so I'll just post the...
I have been upgrading a pair of these very fine speakers, with success. The cabinet is 3.5 cu ft, and is on legs and properly bottom ported at the Fs of the woofer, 25Hz. It has a 12 db crossover, of unknown spec, but it seems to be close to the intended points of the more sophisticated Jantzen...
I have aquired one 2205A. It has never been used. I know It can be used in 4530 horns. What about using it in a Hartsfield? I cannot find any information on thiele-small parameters of the 150-4C to compare it to. The cone is not the steep angle of the 150-4C or the e145, will it handle...
I have been wanting to try to replace my 811C center channel. It's a tall order replacing the 811C so I am curious to see how it plays out. Driver set will be a 2435/435Be on an Array horn and a pair of 2108A's. Similar configuration to the Synthesis set-up. Rob:)
Thought I would share some pics of a restoration job my brother is working on. JBL C38 cabs with D130 and 075 drivers. The cabinets were in bad shape as the pics show. All drivers are excellent. The cabinets are missing one of the aluminum legs. We need one if you have a single doing nothing. ...
My parents bought these speakers new in about 1972 or so. A few years ago the tweeter and cap were replaced by a friend. I doubt the repairs were done correctly. I'm wanting to replace the tweeter with something that sounds a bit brighter. I'm 52 and my ears need the extra highs. Any...
I've always liked the blue used on the JBL pro monitors, and some really generous contributors here did all the hard work a few years back and got a paint code match for it. So I used this formula at HD yesterday: ...
After what seems like a lifetime of delays, I have finally powered up the 4355 variants. I still haven't had time to play with the EQ or run a RTA but the current results are very promising. I am running a Bryston 3B on the top and a Bryston 4B for the woofers. That gives me 150watts and 400watts....
I've build some new JBL 4530 replicas for my living room, loaded with Precision Devices PD154 drivers. 47066 47067 47068 47069 47070 Regards, JR.
I originally made notice for this cloth in the General Information section but it should be in DIY. Too late to move it now. Both colors are cut, boxed and ready to ship. I have already filled a few of the early orders and they are on their way. To cover the needs of most users I have...
I've 2 pristine 2235's doing nothing at the minute so was wondering;Has anyone tried removing the dust cap/mass ring-I'd need 2 replacement dustcaps.................. Cooky Ok CANCEL THAT! I'm on it! Search is a wonderful thing.
Hey, Im the prowd owner of a pair JBL K-120 and K-140. Im very keen to build these ones some nice enclosures, but I have no clue of the recommended volume these drivers should get. They are supposed to run at home, so no big PA-abuse....
