Labhorn query

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello everybody!
This is the first time i appear in this forum. 
Until now i have read a lot in the forum, and i wanted to say thanx for the information given by 
all people! 

I would have a few questions for the people who has built labhorns.

Please correct if i'm wrong, but in every labhorn build which i've seen until now, there were no
rounded parts in the corners, there were only 45° angled parts, right?

Did you use the actual (dxf, pdf) plan from the prosoundweb site? Because i've read that there are a few slightly different versions. And in a topic here i've read that in the plans, are some parts that are a little bit imprecise. (I guess the metric measurements were meant, because the inch measurements
are cruel rounded!)

A little bit other information:

The labhorn was for me a far away dream because of driver costs. But recently i found the LAB12 in the
internet for a very good price and therefore the plan is fix that i want build 4 LAB's!

When the whole system is finished (i hope this will be soon  (i like smileys )) i want to
make mostly psytrance parties here in austria.

Until now I've built 4 MT 121 single mids (b&c 12 pe 32) and 4 mhb 4818 (rcf lf18g401)
My first plan was to build another 4 MHB's so that they are 4 a side, but now the plans has 
changed, as i said above.

For upper mid/hi i would like to use the limmer 042 horn flare + ciare 6.38 mr3 and b&c de 16,
so that i can use passive crossover from h-audio. 

And because of truckspace, i thought to put the rcf's in an es18bph.

Does anyone use es18's and labs together? Impressions?

Hopefully i can also give this forum something, not only taking something! 

thx
Avatron

p.s. I hope that my english was not very bad and hard to read!

	As much as i admire your enthusiasm i would have to disappoint you. Labsubs are definitely the wrong box for psytrance. Been there, done that got kicked badly by a guy with some stupid rcf reflex boxes. So you better look for something along the USB boxes.

	USBs loaded with Celestion FTR-4080FDs have got the kick factor you'd be after. They drop pretty low in stacks as well.

	We used to do quite a lot psytrance parties in Finland with lab + usb + stasys3 combination, and I think they did the job better than well. Before usb+stasys3 upgrade we had hd15+porn horns over the labs. Off course you don't find that much energy below 50Hz in psytrance than in some other music, so just a huge pile of USB's or similar would probably do the job. But LABs are nice challenge to built, nice guys to carry into the woods (:--D) and they offer some clean loud bass, deep extension and accurate transients when those are needed.

	They are great subs, but they are big and heavy, and not needed for psy trance. He will definitely need a dedicated kick boxes with them, which complicates the setup and ends up costing a lot more money. Meaning more boxes. more amps, more transport volume. So if he build 4 lab subs, he will need 4 kick boxes. So double the amp and so on. So in my opinion he better build 6-8 USB subs.

	Just build another 4 mhb 4818, will be by far the most economical solution. 2 mt-121 a side will keep up with ease.

	@all thanx for your quick replies! @marjanm and jwdrain: I thought about what you said, having 2 piles of kick bins. The USB i think wouldn't be the way to go for me, because i already have 4 rcf lf18g401 speakers and i dont want to sell them. And i dont know if the speaker would perform well in this cab. @jerrinomo: Yes, you're right building another 4 MHB's would be the most economical way, but .... in an es18bph, the rcf speaker is tested as far as have read. Having 6 of them per side would go pretty low, i think, and would take less space as the MHB's! And would be 2 18's more per side which can work! Therefore i wanted to ask if somebody could simulate a stack of 6 es18's with the rcf lf18g401, please?

	Addon: I asked for a simulation because i dont how use hornresp. And, is it ok that i asked for a simulation in this thread, or should i post in an other thread? I also saw that a how-to-hornresp thread exists, but there is no working link for downloading! Edited by Avatron - 28 May 2013 at 1:39pm

	Used the G401's in es18bph, they sim very good(search the forum) Usable up to 110hz, above that it get's very honky, used them as kickbins above X1 subs. Scrapped them both and build 4 mhb-46 and I don't regret it!

	Build labhorns and be happy Have been using monoblocks of 4 to 8 labs for years now, at outdoor psy/prog parties here in Australia. Not interested in many other subs, happy with my labs and so is everyone else.

	Build the Lab horns, realise there not what you need, then take that pain you feel to make an informed choice to what your life requires bass wise.
