I think those who went from the 220Ti to the B&C DE250 on the Ewave have been happy with the improvement.

I used Titebond III Ultimate for all my gluing. If you want the easiest finish I would just use two MDF boards for the baffle.

I couldn't find anyones testing with the Beyma so after seeing the statement about the NQ passives I figured I would ask.

Dave (DL86) has 380Ms on the 152WGs.

DE250 $120 from Pro Sound Service
who will also post USPS which makes it cheaper than UPS through PE.

Never been a fan of any of the Selenium HF drives especially the Ti ones.

If you want something as a stop gap and they'll work for you, I'll let you have a couple of NIB/NOS D205Ti cheap.

Yah the shipping is always going to be around 45-55 for flat rate box. I usually just order all my stuff from Leland over at speakerhardware who always has the best shipping for me to OZ.

I will have to figure out if I want to spend more and go with the "upgrade," or not. I was just going with what had been documented and the Selenium was used and then the DE250 for the next upgrade.

But after wanting to clone a few other products my budget is having to go up so I am just trying to see if I can squeeze in 5 CDs at atleast 2x's the cost.

I was going to just use a sheet of 1" MDF for the baffle but didn't know if there was any better way to rid the cabinet from vibrating by using MDF/Ply or MDF/GG/MDF or other?

I know everyone is just adding the lead wrap to the WG but I didn't know if I should try some GG or other combo.

You can use Fed Ex with PE, the shipping is a lot cheaper than USPS. I've bought tonnes off PE with fed ex.

The Beyma kick ass on the QSC WG. Everyone that heard the combo at my place was stoked at how good it sounds.

I want to try experimenting with some larger compression drivers and waveguides though. The 1 inch is fine but I feel the itch to try a 1.4!

Every single item (hundreds) thru UPS, Fedex, bax etc have had a customs fee + GST and maybe duty at this end which have made it more expensive than USPS (<$A1k gross).

Why? All you do is move the BW down so you'll need a supertweeter, will have a proportionally larger flare which introduces listening issues with the larger C-C distance. Go 2" and I'll loan you some JBL2445 or BMS 4590. The latter are still attached to some 2380's.

A bit smoother at very high level playback? I always thought the 1.4" was ok without a supertweeter. Bought some XT1464 flares which I can keep about the same C-C distance as what I have now with the QSC's just about retrofit them.

If I went with a 2" how will I cross this over to the supertweeter? What supertweeter would I use?

Brandon, could you clarify which CD is in your passive XO design.

Is it the CP385 or the CP380??
post #578 of 603
Beyma CP25 supertweeter

I have always heard go things about these.

And what about a BMS 4592 coaxial. Still one driver for the highs to avoid CTC changing much.(depending on WG)

The CP385 seems to be flatter across the higher range than the 380 around 2500hz or so. But seeing Brandon has used them both I am sure he could tell us.

385Nd with the TD12M, and 380M with the 3012HO.
post #580 of 603
hi brandon, why the difference in c.d. based on the woof? i'm sure that i'm missing something, hence my asking...

thanks!!

Catapult just posted that you are hearing some issues with the Beyma?

Any ways here are some pics of the NQ passive using TD12M/CP385Nd and 3012HO/CP380M, and the BBV2 family including the little sub (using three subs in my HT). There will also be a 2512/DE160 No Quarter, and all versions will be done with and without foam.


Just a heads-up, if anyone wants to build the cheaper 2512/DE160 version, the 2512's are on sale for $109 at USSPEAKER.COM till 12/31/10. Two, shipped to my address adds roughly $20. (Only about a $20 savings over PE)

The DE160 I also found on sale, sorta. They're $96/ea at http://www.prosoundservice.com/m9/BC...cy-driver.html

I know the passive XO's aren't done yet, but a person could get a head start and get the drivers.
post #583 of 603
Ive got the TD12M and Beyma CP380M. I was planning to go active.

Do you think the differences between the 2 beymas are small enough that I can use the passive XO for the CP385M?
post #584 of 603
The only problem is the 152i waveguides from QSC are no longer available. Zilch is workin on pursuading PE/Dayton to build/distribute/sell up but that might take some time.
post #585 of 603
I still have 4 of those horns that I'd like to use sometime, so I still am looking forward to a crossover

Bout to finally start building my mains. Anyone know an answer to this before I buy my amps and crossover. Money got a little tight. Wouldnt mind going passive if the CP380 is a drop in replacement for the CP385
post #587 of 603
I was hoping your question was answered but I think the only way to know for sure is to try the XOs and see what happens.

Do you have measurement equipment?
post #588 of 603
No i have to buy measurement equipment. Was thinking of going with the Dayton omnimic kit.

Originally I was going to get a crossover (possibly a Rane), a crown D75 for the CDs and a Yamaha amp for the TD12M. I do like those Digmoda plate amps tho.

I wont try the CP385 Xover unless I know its gonna work out. Rather not waste time and money. Better off to just go right to the active approach if thats the case.

These drivers have been sitting here collecting dust for too long now. Cant find the time to work on this project. I should hopefully start making some sawdust in the next couple of weeks.

Any update on the availability of the wavequides? Kicking myself for waiting.....

I'm told the chances are good on this from PE. No time frame though, there is still a way to go in the process.

Until the QSC horn is available again I'm in no hurry to finish the NQ project. If they do become available again I still have to find a suitable CD for the higher end version. At the lower crossover point I wanted the CP380M just was not as well behaved as the DE160 on this horn. Now the DE160 must be crossed higher anyway, but that is tradeoff I was willing to make on the budget version. If the CP380M doesn't sound better crossed higher (I doubt it will, it appears to be a simple case of the horn and CD not being a good match) then I'm not sure what I'll do. Considered the 18 Sound ND1060 but reviews were not good. Possibly the BMS 4550/4552. Otherwise I'll just go to the old DE250, as it appears to be just about identical to teh DE160 as far as matching the horn goes but should be able to cross a bit lower. Then again you never know what it will do until you bolt it to the horn listen.

The BBV2 will be finished before the NQ, I just got sidetracked helping a friend build a home theater in his basement, so I haven't had time to finish building the crossover on the BBV2 and listen to them. By friends theater will be pretty cool though. Bookshelf size speakers based on the Zaph ZA14 woofer and Scanspeak 9130 tweeter (old Peerless HDS). Crossed to four Peerless 12" woofers. Should be nice.

What about the Faital Pro 200 I think it is?

I have seen tests with this driver(Klipsch forum) and it can be crossed at around 500hz.

I think the No Quarter could become a cult speaker where it becomes a highly prized speaker due to the limited availability of the waveguide. I also don't think it is an exercise in futility as QSC was really cool about selling these waveguides and a lot of them were sold before their new waveguide design was implemented. I have 10 of them that will be pressed into service in one way or another. The reason the NQ was attractive to me was due to the approach that you take with your speaker design. You clearly 'get' what is going on and it is clear to me that a final product would be a really well designed speaker that would not fail to please.

All is not lost for those of us who are neophites in speaker design and wish to use this waveguide. Most of us are familiar with the 'econowave' and 'show us your meddle' threads at AK and Zilch's efforts there. Zilch clearly 'got' speaker design and has posted many crossovers with different combinations of drivers. He did choose compromises always using the same breakdown, trapezoid kit enclosure where as the NQ is a purpose built, few holds barred, system. I'd gladly build a memorial 'econowave' speaker system that would sound great, but the NQ is the holy grail for this waveguide.

Thanks Brandon for your efforts and teachings and for the inspiration to achieve considerable sound quality through DIY efforts.

The 200 is a 2" CD, it can do 500Hz but not very good above 10KHz. Do you have the link from the klispch forum, I would love to read the comments about the > 10KHz performance.

You can easily combine the NQ cabinet design with Zilch's Ewave Deluxe driver/crossover design. If you want a better mid buy a TD12, take measurements and modify the Zilch topology. Zilch gave us all the tools needed.

Hi Guys - Good News - the QSC Waveguides are now being stocked buy Parts Express !!! - maybe someone can let Brandon know that they are available again - I am also hoping to build Brandon's waveguides... those that will have the better parts in them than the Econo - waveguides, but I am waiting for his passive crossovers - all very exciting - Best Wishes -

Any updates on the BB v2? Did you ever get a write up on it?
post #599 of 603
Thread Starter 
A little update since people are asking...the BBV2 should be playing in my HT by the end of the month, just need to assemble the crossover. It may take some time to tweak things, but for the most part it should be a done deal soon. As for the NQ I'm not sure what I'm going to do. The QSC is back but who knows for how long? The Eminence drivers shot up in price. I'm still trying to find a "high end" compression driver. The budget model uses teh DE160 and that is what I've been using matched to the 3012HO woofer for almost two years, but I really wanted to find a driver that let me implement the design philosophy fully and the DE160 must be crossed too high to do that (still sounds really good though). I do have a couple horns and compression drivers for auditioning to shed some light on the matter but all that takes time. And right now it is summer and the priority is: drink and chase women, finish a center channel for a friend (with AMT tweeter, kinda neat), help another friend finish his basement home theater including the sound system which is my design, finish the BBV2, do some projects to test a few tweeters and woofers for future projects, finish my Statement Monitor build (had the parts since so why not?) and finish my multi subwoofer build. In that order. Checking out leads to decide how to complete the NQ isn't going to happen until winter.
