    Big Loud Party Speakers

    Both systems are big and bold and will certainly impress... I do prefer the newer designs as tonal accuracy and imaging are important to me, but for the cost of a pair of 43XX clones or even fine vintage originals, it is hard to go wrong.

    I really value this advice.

    I too am looking into building 2 pairs of 4355 or 4350,s for a loft style party space

    Having used Urei 813B,s for a while I really seem to be drawn to these type of JBL enclosures.. sure they're big, but for big rooms they seem to really hold their own. Solid.

    They are beautifully simple and cost effective to build.. and with veneers they can get very nice

    I keep going over options for drivers, amplification, processing,,, its fun to be inspired by all the designs and the sound of JBL

    Hi Charles ,

    I think you could do a lot better with something newer for this application. Bare in mind , the 43XX were designed for studios -treated and specifically designed spaces.

    Although , at one time , I did have 4345 and 4435 running in my painting studio . The sound was very good ,but for the same money I could have bought something that would have out performed it .

    Im all EARS shoot, what new system would you suggest. One caveat, I would love for it to be sourced from Canada and within a 1000km radius.. drivers would maybe be manufactured elsewhere..

    The aim of the project is studio sound.. no mp3, all uncompressed files, room will be treated Im told.. would like to go with walnut veneer I am old school and like walnut as you will see from my hand crafted attached pic in solid walnut/maple

    I agree that new can be good.. I also know that some of the magic is lost in todays systems and the passion that "older" JBL can inspire in ppl all over the world.

    We are auditioning different local systems but I havent heard what Im looking for yet, and when we do the price is ridiculous, took a professional cabinet course to get the price down and build it myself. Every time I see the incredible DIY work here it inspires me to dream of a different era where speakers were big, bold and music was too :P

    I have a pair of 813,s and there are strengths and weaknesses in the design. My room is large enough for these speakers, but I barely push them. This will be a more demanding environment so we may have to go with more powerful drivers.. and add independent subs & the extra 12" as with the 4355

    The plan is to build something scalable, as well as a demo system to try different approaches and drivers. Project wont allow for horn loaded for size and looks.. Dont have the money to pay for an entire system off the bat..

    going with two stacks first:

    First is the sub woofers for the system. Going wit a popular design and 2226 drivers that I have already..
    http://mainkas.tripod.com/page/audio...ngen_sub2r.htm

    for the tops it will be very similar to Lasse's project using my 813 donor cabs for testing, 2395 with BMS 4590 (or 2397 wood variant & TAD$$) 2405 or ET703.. BSS Soundweb London processing.. if needed a separate 12" driver in its own box can be added. http://www.audioheritage.org/vbullet...560-4355-clone

    There will also be the booth monitors with dual 12" drivers and an A290 style wood horn.

    Tweeter array perhaps wonder how you guys feel about that LOL

    Amps will be refurbished Crowns, macrotech 3600 and ps-200,s & D75 as well as some Bryston 4b,s

    Hi Charles,

    sounds like an interesting project ... would be very useful if we had a loose budget . Tons of members within that radius with and equal amount of knowledge and ideas .

    I really dont want to start hacking Mesudman`s thread to discuss more of these off topic plans so I`ll try to be brief and to stay on topic with the 4355 clone options.. If the moderators or Mesudman feels like this is too much off topic, I will make another thread once construction commences or feel free to move this post

    * I feel this thread is a good indication that others are interested too in building these bigger older systems.

    The initial budget is very tight, we want to start making money with the space to finance upgrades.. We also need that demo system to try out different options and iron out details before commiting to build the 4way or 5way stacks. Once finalised on design and driver/amp/processing choices.. The four stack system with the additional two booth monitors and all the processing, wiring and cabinet manufacturing/sourcing, drivers, amps.. the maximum is 50,000 CAD/USD.

    The first system will be my pair of Urei 813B with two subs using the 2226, pricing out materials tomorrow at my friends CNC shop for subs. Right now the Urei`s are powered by two Bryston 4B,s in bridged mono. Original Urei time align networks.. the subs will be powered with second hand crown amplifiers, and we will have to find a way to integrate them into the Urei setup.. We have a lot of Crown amps around, we will probably try using something we have first.. One of the lead repair techs at Soundcraft Canada (JBL,s Canadian dist.) is good friends with my partner, and he takes great pride in restoring our amps as well as giving us advice..

    The upgrades will take place over time. I will be testing locally sourced Transparence 15'' drivers in the 813 enclosure first before I commit to buy anything, then try some refurbished JBL drivers we have.. If the TR drivers are more power hungry they will be Macrotech driven for the midbass.

    First thing we will source will be a set of 2405 and used/refurbished D75A, and borrow a set of the 2395 and BMS4590 from a friend for testing. We will try the PS-200 on the 2395/BMS4590.

    I am manufacturing at my own cost a set of A290 horns and double 12'' drivers for the booth at a later date, but first will be the set of 2397 horns - from solid walnut at my friend`s cnc shop. The brass throat adapters will be manufactured by my friend`s cnc metal shop. This is something I always wanted to do, and one of the reasons I took my cabinet makers course.

    We will be borrowing/demoing a Soundweb London from Soundcraft for testing and dialing in the 4way system.. we may add the 12'' enclosure to go 5way.. or pair up the 2397 with the 2395?? This I have never seen done. I have seen double 2395 on a stack, both powered by BMS 4590.. we will try everything!

    suggestion

    A few idea's, thoughts and a sales pitch.

    (1) I have a pair of 813B cabinets here in central NY you can have for dirt cheap. even have the grills ( need a little repair though ) Also have the crossovers.

    (2) Go newer for the HF....a seller in ohio on ebay has a pile of 2352 1.5" horns for a decent price. Put a 2450SL on those and you are DONE. add UHF if you have extra bats around you need to deal with. I have (4) trap cabs with 2226G and 2352/2450SL that I built that are very close to the JBL 4726A in size. Easy to EQ and very smooth. The older metal lens are pricey to source, REQUIRE uhf and have vertical pattern issues.

    (3) Do not use the D75 for any PA project, period. Get a CT210 for cheap and put a comp/crossover card in it. the d75 is a great near field monitor / headphone amp but is TOO SMALL for any direct compression driver app - one clip and it's all over. KACHING...

    (4) I have (4) techron/GE 10KW monoblocks if you want to do subs right. Put the same length wire to each cone ( up to 16 eight ohm cones per amp ) and you have perfect phase integrity.

    (5) instead of a megabuck processor how about a crown/BSS 8810? combine 8 inputs with 10 outputs that can have all kinds of delay / filtering and such...500 bucks....easy to setup with an ethernet cable.

    I know that Acoustilog on at least one occasion built a TD-1 (a time-delay/crossover unit, first built for and used at the Garage, from my understanding) for use under a pair of 813 monitors for a nyc hip hop studio... I am unsure of the crossover frequency that was used... but do have the unit if you want some pics of it.....
