I hear you! I'm going from a simple 5.1 straight into a 11.2 with active DIY LaScalas and DIY subwoofers.. Money and time are against me.

YES! I'm able to audition the dB-mark XCA-26 for 14 days . Only shipping has to be payed if I return it (like 10 euros). Maybe I can find a Xillica somewhere too, which I can use to compare them.

I know I cant deduce quality of sound from a spec sheet, which is why I'm asking here was hoping that maybe because of the included chips/parts it was maybe possible to establish a level of subjective quality. Thanks for the link! DAC Chip: Texas Instruments PCM1798 ADC Chip: Asahi Kasei AK5388 DSP Chip: Texas Instruments TM320C6726)

I would, and maybe I will, but I have a lot of upgrades planned. I'll also need several crossovers in the end, including one for my height speaker and subwoofer project, which is why I can settle for a les qualitive xover for now. Will 100% end with the Xilica (in the near future)!

Still kinda "sad" I went for the behringer.. Trying to sell it now so I can buy the Sabine NAV. A recent flyer got me thinking though.. would you happen to know something about the dB-MARK gear? I've included the flyer below.

Still, 250/ch is impressive! Is the horizontal dispersion of a tweeter in that kind of horn (or the K77 horn) wide enough? I believe you, just bit surprised. The vertical curve is necessity though? Is there any coupling that you know of? Cause the K77 can't keep up with the bassbins and K55 when driven to their "max", not sure if thats even a problem, but some extra dbs in the tweeter range is surely welcome.

Hadnt thought of doing it like that.. Was looking for a different configuration though. Something like the MCM1900 which uses several smaller horns and drivers, instead of the K-402 and the KPTXII 12-inch Tractrix® module. Although they might be able to produce high-fidelity sound for several hundreds, maybe even thousands, they are next to impossible to get my hands on. I have looked at several ways to obtain the legendary K-402, but I haven't found any dealers in Europe which could sell them to me, and although I have found a way to buy them in the US I was told it would be crazy expensive to ship so that plan is on hold for at least several years. I was told I could use a Seos 30 horn (EDIT: or a jbl 2360? those are cheaper) to get as close to the K-402, but those horn also cost like 500 a piece (which is a bit too much for now, maybe in the near future). Using a 12" for mid-bass might be a good way to go though! Maybe I can emulate the design and use a sub I can easily get my hands (the EQ844, which is very "similar" in design to the MWM / Jubilee bin) from 100 to 200hz (or maybe even 300hz), the LaScala bin from 200-300hz to 600-700 (not sure how high the LS can go with decent efficiency etc) OR a front horn loaded mid-bas woofer (like in the Grand Cinema) and use my PH2380(horn)(or maybe one with a wider dispersion pattern? Not sure what is ideal for a concert/stage speaker) with a driver like the Faital HF200 (109db SPL and 70W power handling from 900hz, AND recommended by guys like Bob Crites). This looks like a project that would be in the price range of our organisation (and my persuasion skills)

The top bins are for later, if I even have them made. I'm doing a separate bin setup like the LS II. I have a LSII sitting in box at my home at the moment, which I'm hoping to sell for a fair price so I can finance this project. For now the builders can use it to model the clones of. By using separate bins I can easily stack them (I do have to figure out how to place the inputs on the back instead of ontop of the bins).

Awesome thread! Some promising remarks about the simplicity of the build! Havent found any specs (power handling, sensitivities etc) about the MWM / MCM1900. Why is that? Because they are not always the same or? Is there maybe an "average"? Or some recommended drivers? Eminence Kappa 15C for the woofers I'm guessing, but what about the tweeters? Some wild recommendations so I can maybe have a look at how much the total project would cost. Maybe some JBL 2445/2380 horns for the midrange? They go for crazy cheap over here and seem perfect for a PA goal (maybe not the same klipsch quality though..). Again, no hurry and no problem in suggesting things youre not completely sure about, it's only in the planning stages. I will check everything again and again before I start the build, if I do.

Thanks! Absolutely no hurry, or problem if you dont find them!

Yeah, I'm getting some greaat input over there! Was going to tell you about that haha! Just forgot :s

Might be a worthwile plan! If we can build a pair of those with our organisation, we could maybe build some other bins/"flightcases" for the other drivers. Renting something like a line array or other decent audio installation might cost more to rent if we do that every year. Probably around 1000-2000 each year... If I can supply our first year with the amps, cables and mid/HF drivers we could build all the cabinets (we are with 40-50 people so workforce is not something we lack) and buy ourselves the appropriate gear over the years, to run it without my personal input. That might be a plan I can convince them on.

Could be that it is normal practice in this kind of situations, but did you use a mono signal? And only a 2x120W 8ohm amp for everything? Awesome! What about those tweeters. Does it matter how the curve goes? Is the dispersion wide enough to put them vertical (with the tweeters themself horizontal) Or would a more horizontal placement/curve be better suited when only using 3 horns /side? Will have to make my own flightcase like that, beautifull example though, thanks!

Whoa, seems like a good idea I left the task to local woodworking atelier (with speaker building skills). They will be building a few for me, but before they do they want to build a prototype to test how it holds out. This will cost me a few extra euros, but as you say it's worth to get a decently build bin! I'll pass your info along so they know what to focus on. It's to good to know they also the right tools like specialised saw tables for the tricky angles.

I think I kind a misunderstood :s You used the LaScala bins in combo with the complete MCM 1900 array? Or with LaScalas instead of the MWM bins? And if you mean mids, you mean a different set of drivers as the K401 horns? Like a MSSM? Also what are the specs on those MCM Piezo arrays? Cant seem to find any info on them. That aside: .... Ö Would have loved to have met that setup ! Pure powerrrrr

Yeah, I'll probably stick with the 3/4" in the inside and adjust it for 1" sides. Shouldnt be to hard to calculate. Thanks!

It's crazy how generous! Cant believe it actually! Klipsch lovers over here also have a tendency to sell primarly to people who are as much in love with the brand as they are, so I guess it runs in our collective veins I know some klipsch owners from second hand sites who could maybe help me, but none with as much experience as the ones on this forum. Might have to look better.

Might build them one day though! They look pretty cool! for now I'll stick with the LaScala tower (with more powerfull woofers and an upgrade from the K77 to the CT120 for better power handling) Slightly related question, would you happen to be able to recommend annother klipsch tower/stack design that would be able to achieve a 100db output over a distance of 30-40 meter (100-130 feet)? I'm guessing the MCM combo would be able too. Maybe interested in designing+building/buying second hand our own sound system to use over the years. That way I wouldnt have to put my own personal gear in jeopardy every year (it's an event held by our youth movement, so I have no financial gain by organising this).

Probably cheaper to move out to you guys, than move those MWM bins to me...

Shipping those would be crazy expensive I fear Love your offer though! You people are crazy generous Ö

Belgium :sssss

Didnt have any time to go through it, but will tomorrow! Did have a quick read in the "block party" thread, interesting stuff! Might upgrade to some MWM bins or the like in the future, but the LaScala tower is a start

Will look in the archives later! Google searches havent turned up much usefull info though..

That looks like a beast ! Would be perfect for my goal, but the main goal of the LaScala tower is using the gear I already have. PS I also have 4 heresys I could use.

Yeah, I still got time probably a few months ! If we decide to use the LaScala towers we will be testing them first too ofcourse. Not everyone in our organisation is convinced, so I'll probably have too blow them away first to show the true power of Klipsch!
