OMG!........What's that????

[ThomasW]

Haha, mine's bigger than yours.........:heh:





Now I bet there are some skeptics thinking, 'that isn't a real speaker, he just created those images with a graphics program'.

Not true......... :B

So, do you have an earthquake proof version of that for Californians?

You know what they say, the bigger they are, the harder they fall! :uhoh:


They do have that 1+1 look about them, though, don't they?

That was also my first thought upon the picture popping up. Put some 1/2" steel plates on the bottoms of those things for use in L.A.

OK, it was my second thought, right on the heels of "coooool!"

Dang! Gotta love it! If those puppies vibrated before, I'll bet they do a good Elvis impersonation now. :LOL:

[ThomasW]

The 'flexible flyers' are pretty much maxed out as for as weight limits are concerned. Since the mass is concentrated, and since there's a good sized foot pad they aren't all that tippy.

These puppies can ROCK..........Dialed in with some LFE help from the Behringer, the bottom end is for all intents and purposes as good as that from my small IB (4-Shivas).

Jon's scheduled to be in Denver the 3rd or 4th week of March. We'll do some big time testing/measurements then.

Plan now is to make bass, and MTM modules. Then the speaker can be used as either the 'regular' Arvo, or with the addition of an extra bass module the Arvo-Ultra.

If we were ever to actually build and 'market' a speaker, this would be it....(yes it's really THAT good) ......But I'm WAY to lazy to get on that bandwagon again..... So instead we'll just give-away the plans for free....... :B

I'm pretty sure Jon will write up an article for publication in AudioXpress.

Talk about DOMINATING a room! WAF factor of -23.7. Ahhh, dipole - I bet they are clean and open. I that your new SS tweet?

Dang, I can see I'll have rebuild my Bobs!

Talk about DOMINATING a room

Agreed, they certainly are way too tall for my family room. They'll stay tall until we do the measurements. When I build the finished modular versions, they'll be the standard Avro height. I'd keep the height if I didn't already have 93" tall arrays in the HT. I will build the upper modules just in case.......

that your new SS tweet?

Yep and it's sweeeeeeeet!

Dang, I can see I'll have rebuild my Bobs!

Yes you will....:B

Yeah, I think it's a close call between my old X1 Klones and the "Arvo Ultra" (maybe it should be "Arvo Unreal" ?) as to which has a lower WAF. The original concept speaker is more petite, and a whale of lot less imposing on a room.

'Course, the one's with dual 11" Titanic's won't plumb as much depth as 4 DPL's, but then I COULD add a Bethoven style "auxiliary" dipole woofer, or just a sealed monopole below 40-45 Hz to accomplish much the same.

Now, I wonder if I could get away with an HE15 dipole sub on a big baffle, like that Tumult based one with the array of midwoofers one guy is trying to market? Just the LF baffle on a 3"X5" under the screen? Hmmmmm. Bet it wouldn't be easy to avoid having a little "baffle flex" with one of those, either!

Nice work Davey

Are you using the SL approved anti-gravity sky hooks?

[JonMarsh]

Davey,

What frequency range to you cross from the Excel Midwoofer to the dipole woofers? How much do those upper baffles move when you start pushing things?

~Jon

[Davey]

Anti-gravity sky hooks. Actually, when the lights are out it looks like the panels are suspended in mid-air. Some fishing line or alternative would be even better.

The main panels don't move at all even when playing very high SPL levels. The xover to the woofers is about 120hz and the slope fourth-order electrical so the excursions of the W22 are not that great. I've never seen it move more than about 0.25" P-P.

I'm working on a notch filter for the woofers currently. They peak at about 230hz because of the "W" enclosure.
I also have a set of DPL12's mounted in "H" baffles that I was using previously. I like the force cancellation the "W" baffle yields and I already had the eight Madisound drivers so I used those instead.

Imagine an Orion system only capable of quite a bit higher SPL levels and you'll have a sense of the way it sounds.

Cheers,

Davey.

Hello Thomas,just wondering whats happening with the Arvo Ultra{OMG},are you still using them and have you made any changes.Lazz.

[ThomasW]

Hi,

Well remember our motto "slow work takes time..."

At this point they are still as you see them in the pictures. They're being used everyday.

Work on the finished speakers was on hold until we completed evaluating different woofers. We chose the TC-Sounds 12" TC2+ from O Audio. Factored into this decision was the desire for most linear output to higher frequencies given the ~175Hz XO point.

Finally all the materials needed to build the 'finished' project are in house. The remaining TC-Sounds 12" TC2+ drivers arrived late last week. Construction will being later this week.

They will be modular for expandability and portability. There will be a MTM module and a pair of WW modules. That way they can be set up as MTMWW or WWMTMWW, depending on whether or not a sub will be used.

The XO won't be fine-tuned until next month, when Jon comes out for a mini-vacation.

[Dennis H]

Yes!

Hey Jon (Mr. Sim-Man extraordiare), please do work out XOs for the MTMWW and WWMTMWW configs. This thing has really got me interested. The Orion looks nice but it just doesn't have the full-range SPL I'm looking for (as an unapologetic aging rocker who also likes loud monster stomps in movies.) :W

Well, at least we understand each other's motivation, because they appear to be nearly the same. My other issue is that I wanted to try going passive to make it possible to easily switch amplifiers, and to not have a rats nest of electronics just for the mains.

As previously noted, I think the LspCAD predicted response (no external EQ) looks quite promising.




This weekend I'll be doing inventory on crossover parts and putting together an order. I'm considering using some "botique" capacitors on the tweeter crossover, too, just to make things interesting... :banana:

I already have all the key inductors. They're pretty scary looking, sourced from North Creek Music. AWG 12 wire.... :B

I could use about a month off to get stuff done on all these projects I've got in the air... maybe I need to think about the possibility I'm taking on more than I have time for? Well, I'll just have to fit it in somehow!

~Jon

[Al Garay]

Jon,

Figure out how to get by on 4 hours of sleep and promise yourself that you'll take better vacations than a week in Colorado buidling crossovers. I was thinking a week in Hawaii with a beautiful lady. Heck, they just have to be better looking than Thomas.

[Dennis H]

"Doc I'll get all the sleep I need when I'm dead."

Wade Garret (Sam Elliot) in Roadhouse. :LOL:

[ThomasW]

Dennis,

Now that Jon has all the necessary drivers 'in-house', the plan is to have the all passive XO for the MTMWW completed ASAP,

With that design completed we can extrapolate an all passive design for a WWMTMWW. But we won't be able to actually do any hands-on measurements of that configuration, until Jon comes to Denver (tentively scheduled for the 2nd or 3rd week in June.)

Obviously if one wants to bi-amp a WWMTMWW, information for that will be available as soon as the all passive MTMWW XO is completed. Biamping has been my plan all along, since unlike Jon I don't have any 125 watts/channel class "A" power amps sitting around......

[Hank]

Do my eyes deceive me? Did Jon really type those words? My bubble is burst :cry:

... maybe I need to think about the possibility I'm taking on more than I have time for?

:rofl: Hmmm...perhaps a remote possibility.

[JonMarsh]

Talk about being quoted out of context! :W Well, maybe not...

Actaully, when I wrote that, I wasn't doing too badly. But shortly afterwards I bought a used NEC 9PG+ CRT projector, and started a major living room re-org necessary to support it properly.



Now, THAT was biting off more than I have time to chew! :E

OTOH, I've gotten tons of stuff done in the last two weeks, including most of the living room re-org, getting a suitable table for the 125 lb. projector, getting my screen situation sorted out with a new Carada, and setting up a new computer workstation and remedying a long standing glitch in my desktop by replacing the MB, and doing a transplant of the system into my ATC 200 case which has been sitting around unused since I transferred the HTPC to the ATC601.

Cap and coil inventory about done, now I'm drawing up the spreadsheet to order parts.

And two more TC2+ have arrived... now have all drivers.

On the downside, I got assigned two more hardware projects to do in the next 2-3 month by the headquarters folks in Austria- this I didn't need, as I already have a very busy summer work wise. Plus, our synergies with the HV IC relocation to Singapore aren't synergizing, and now they're trying to schedule a workshop in July for knowledge transfer to the new hires...

It's going to be a gruesome summer...

Slow work takes time....

~Jon

[Hank]

Yes, that CRT projector will be a chore. One of our local group guys bought a used one (he just HAD to have blackest blacks). It took 6 of us to install it, including someone in the 130-degree attic drilling through the studs to mount the all-thread rods to hang the thing from. My friend has been tweaking/converging the monster for a year and is considering coming over to the light side with a digital projector.

As for your work schedule, Jon, HQ will continue to pile projects on you as long as you continue to complete them on time :roll: "They" don't seem to mind your loss of free time. Oh well, tequila's good for that. 8x)

[JonMarsh]

Oh well, tequila's good for that.

Yeah, I like mine in the "Orozco Margarita", a specialty of my favorite local family owned Mexican restaurant. 8x) arty:

Yeah, I kinda like those Darth Vader blacks myself; this is my 3rd CRT front projector; had a digital before this 'un. I think it comes from watching too many SciFi movies; outer space just doesn't look right when it's only medium gray...

Mine's not going to be hung; it's going on a low table, already found and purchased, but not yet assembled. The physical and electrical setup will take some time. Scanning rate up to 1600X1200 on this 9PG+, but I'm planning on setting up and running just 1080i. The NEC's have filtered tubes with excellent color reproduction overall; I'm just looking for something similar in color quality and contrast to my NEC CRT presentation monitor (29"), but a bigger picture.

You're probably right about the projects thing, which is why delivery on some items are starting to "slip"....

[David Meek]

Mine's not going to be hung; it's going on a low table, already found and purchased, but not yet assembled.

Wouldn't that leave the PJ open to being bumped, nudged, knocked or otherwise inadvertently moved out of position? After going through the rigorous setup demanded by 3-gun CRTs, that'd be painful. Just thinking aloud. . . .
