TheEAR Posted February 20, 2008 Author Share Posted February 20, 2008 Thank you, When building a cabinet like this,the time and effort has to be worth the pain. In this case the output and extension will be worth the build effort. Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted February 20, 2008 Share Posted February 20, 2008 Very nice. You can literally see the time that went into the build. Quote Link to comment Share on other sites More sharing options...
TheEAR Posted February 20, 2008 Author Share Posted February 20, 2008 Tonight more pics of progress,good progress. Just waiting for acoustic material (by Friday should be home) to cover the inside walls. This thing will end up at around 210lbs empty. With driver 250lbs. Less heavy than my dual TC-3000 15" beast ( ~320 lbs). My largest sub is yet to come as my ACoupower 18's arrive,it will be a monster of a cabinet. In the 400 plus lbs range,again dual cabinets. I am on a DIY roll here [] Thanks for all the good comments. Quote Link to comment Share on other sites More sharing options...

Jay481985 Posted February 20, 2008 Share Posted February 20, 2008 A the port is flared at both ends. you call that a flare? B the 40 pound driver is there to do a job and not for show. you call that doing the job? C weaksauce,no the weak sauce is to own a SINGLE driver and have no proper cabinet and amp. its called I am in college and they frown on power tools in the dorms, they frown on my rf-83, they frown on anything I own. The RA asked me why I need my denon reciever and dvd player, why i need these speakr, etc.... Do better than me build wise and we talk. Plus a couple of ACOUPWER are comming...

BLSamuel Posted February 20, 2008 Share Posted February 20, 2008 Jay, Maybe you should hang with some art or architecture students at your school. The arts building and college of architecture where I went to school both had decently equipped wood shops and I think also had at least one shop in the industrial technology area ... of course that was over 20 years ago and you might have to prove you're an art / architecture student and have a valid class project in order to use the power tools nowdays... and probably sign multiple waivers, etc (do universities still let college students use power tools anymore?) Might have to go the compact route to fit in your dorm room with RF 83's - maybe size to fit under your bed? (your RA apparently has no musical taste). Maybe you need the RF83 as Jubilees won't fit in the dorm (and cost a lot more). All these insane subwoofer projects makes me want to build one for myself ... but mine would definitely be a very minimal low budget affair and even that aint' gonna happen anytime soon.... maybe one of those tapped horns Doc built but would probably be too difficult to get right. Can't wait to see some photos of the beasts people here are building Quote Link to comment Share on other sites More sharing options...
TheEAR Posted February 20, 2008 Author Share Posted February 20, 2008 Flare ,yes both ends you have 3/4" roundovers. Enough with an 8" port. The air velocity will not reach critical where noise can be heard. Doing the job ? Yes a well designed 40lbs 18" driver in its optimal configuration can do more than heavy drivers ...with no boxes to boot. Quote Link to comment Share on other sites More sharing options...

Jay481985 Posted February 21, 2008 Share Posted February 21, 2008 Flare ,yes both ends you have 3/4" roundovers. thats like a trim pieces..... a real flare is double the size of the port [] Enough with an 8" port.

TheEAR Posted February 21, 2008 Author Share Posted February 21, 2008 Real flare, you will teach me what a real flare is ! [:^)] Back to this thread main topic,my EBS cabinet build... Quote Link to comment Share on other sites More sharing options...
Jay481985 Posted February 21, 2008 Share Posted February 21, 2008 Real flare, you will teach me what a real flare is ! hmmm As a service to our customers, we have tooled massive 7" and 10" I.D. ports. The 10" I.D. port is a perfect match for one of our 18" Drivers or two of our 15" drivers. The 7" port is a perfect match for one Acoupower 15" driver. Each Port consists of large 0.062" aluminum flares for each end, and a long thick walled paper tube to run between the flares. The 10" tube is 15" long and the 7" tube is 20" long. Both may be cut to another length as needed. An Acoupower 15" Driver and 7" port provide a new level of performance to high end Studio Monitors and High End Home applications requiring lower tunings. The geometry and thickness of the Aluminum flares as well as the thick wall of the tubes give these ports tremendous stiffness and strength. Both the flares and the tubes are made locally. To be effective, at least 3-4" of space around the flare openings should be free of obstacles both inside and outside the box. Please note the flares are enormous. The larger ones have a diameter nearly the same as that of an 18" driver and the smaller ones have an O.D. larger than a 12" driver. Basic drawings are available below.

Guest srobak Posted February 21, 2008 Share Posted February 21, 2008 "The 10" I.D. port is a perfect match for one of our 18" Drivers or two of our 15" drivers." I've done the math 3 times on each of 4 different cabinet sizes, while trying to tune for 32Hz - and this just does not compute... Quote Link to comment Share on other sites More sharing options...
TheEAR Posted February 22, 2008 Author Share Posted February 22, 2008 Behold the Acoupower 18!!! A monster, Neo motor and all. It is a true brute. Comercial subs beware. [] Quote Link to comment Share on other sites More sharing options...
