HPower Posted December 10, 2019 Share Posted December 10, 2019 Yesterday I came across 4 used Eminence LAB 12 drivers that I ended up getting. It's not that I needed them but at $400cnd for the quad, I figured, what the hey. I first thought I might build 4 of Wayne Parham's 3Pi subs... they are a 20"x20"x20" box with a 4" round by 16" long port. Then I did a little reading on the LAB12 and it seems they might be well suited to a horn loaded cabinet. I already have one F20 sub and two Exodus Anarchy 6.5" 25hz tapped horn subs, that really work nicely, so I do understand what horn sub base is all about. Anybody with any experience with the LAB12s... Calling Carl, Claude, Jason ? Quote Link to comment Share on other sites More sharing options...
jason str Posted December 10, 2019 Share Posted December 10, 2019 To make the most out of those ? 2 x double 12" Tuba 60's. Quote Link to comment Share on other sites More sharing options...
Edgar Posted December 10, 2019 Share Posted December 10, 2019 I have no direct experience with them, but they simulate extremely well in tapped-horns. Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted December 10, 2019 Share Posted December 10, 2019 Those speakers were a favorite a few years ago over at DIYAUDIO, for use in the "tapped horn". The cabinet must be designed for those woofers, but there is a very nice program that will help you (HORNRESP). Do NOT use a generic cabinet for the woofers in a tapped horn design and remember that the title, "tapped horn" is a bit of a misnomer. They are more of a transmission line design and do not share all of the advantages of a true compression loaded horn (although, for the bandwidth they can be conveniently sized). Good Luck, -Tom 1 Quote Link to comment Share on other sites More sharing options...
jason str Posted December 10, 2019 Share Posted December 10, 2019 Works in any slimmer THT design as well. Quote Link to comment Share on other sites More sharing options...
jvs1670 Posted December 11, 2019 Share Posted December 11, 2019 I used one in my THT LP, dimmensions of the cabinet is 18"x18"x60". BFM plans, it sounds awesome. Quote Link to comment Share on other sites More sharing options...
ClaudeJ1 Posted December 11, 2019 Share Posted December 11, 2019 I have some lumber that's precut for a pair of LAB 12 Tapped Horns that are flat from 20-60 Hz. I have called them my "coffee table" subs, as designed by someone else. Nice buy, BTW. My flat packs are spoken for, but for a guy like you, this should be a super easy build. You just need to make sure you have speakers that can cross at 60 Hz. and your are all set to have the best low bass you ever had. Believe me. You can't go wrong with 4 of those on the center of 4 walls, so once built, you will want to sell everything else you own, trust me on this. 1 Quote Link to comment Share on other sites More sharing options...
ClaudeJ1 Posted December 11, 2019 Share Posted December 11, 2019 There's no need for an access door for the driver, as everything can be easily done from the mouth of the horn, which simplifies the build. I also have the layout for 4x8 sheets of plywood, which I'll look for later. 1 Quote Link to comment Share on other sites More sharing options...

For HT and music, I strongly recommend the JBL research of having 4 identical subs in wall centers as the ultimate setup. Todd Welti did his homework, that's for sure. multsubs.pdf 1 Quote Link to comment Share on other sites More sharing options...
HPower Posted December 11, 2019 Author Share Posted December 11, 2019 Thanks guys for the suggestions so far! I agree that the Tuba 60(s) would be killer subs, but the size of these B#ggers might be an issue for my room. And my room is in the basement, which is a chore to lug big boxes down into. My F20 was a struggle and then my Jub clones were a real B!t@h to get up and down the stairs, even with four guys! Claude's plans look to be much more manageable to build and transport to the basement. The multiple sub technique is also what Wayne Parham endorses, hence why I original thought of going with 4 of his 3Pi subs. Quote Link to comment Share on other sites More sharing options...
HPower Posted December 11, 2019 Author Share Posted December 11, 2019 My memory is not what it should be, sucks getting old, but was the Spud and or Super Spud built around the LAB12 driver? I did a google search, but I did not come up with plans for either of those. Quote Link to comment Share on other sites More sharing options...

Chris A Posted December 11, 2019 Share Posted December 11, 2019 46 minutes ago, HPower said: ...but was the Spud and or Super Spud built around the LAB12 driver? The Spud uses dual 8" woofers. The DIY version typically uses a Tang Band woofer--W8-740P (of which I just replaced four of these in the two DIY SPUDs in my listening room). Here is the thread where the plans used to reside--before Photobucket unceremoniously pulled their own plug. I'll post the relevant info below: THSPUD%20Rev4.pdf This could easily be expanded to accommodate the Lab 12s by increasing the thickness of the SPUD design and moving things around just a little in the driver area, being careful not to constrict the last bend in the horn before the mouth is encountered. Hornresp simulation of the Lab 12s with the SPUD basic horn design could be used. The reason why I put all this information up is because the pair of DIY Spuds in my room carry the frequency response from 31 Hz down to 13 Hz (-3 dB point)--without boosting EQ... The only comment I'll make is to make sure that the horn paths are sealed up well around the drivers... Chris Quote Link to comment Share on other sites More sharing options...

Edgar Posted December 11, 2019 Share Posted December 11, 2019 An old post of mine showing that the 10" K41 would work really well in a Spud, if it could be made to fit and if you didn't push it too hard: https://community.klipsch.com/index.php?/topic/126476-tapped-horn-sub-woofer-build-spud/&do=findComment&comment=1444452 Quote Link to comment Share on other sites More sharing options...

There's a harman white paper on this as well. 1 Quote Link to comment Share on other sites More sharing options...

Best suited to THT, both THTLP types & Tuba 60. 15-18" wide versions or double 12" Tuba 60. Quote Link to comment Share on other sites More sharing options...
