Hey guys...we need a little rallying here... - Page 230

That's great news! Excited to get my AT1's.

Plase someone. Is the deltalite kit under 60 pounds with the flat pack

itll be close when fully assembeled. it uses a 2 CUFT flatpack (the 12), which if it weighs as much as the one for the Tempests did that alone is ~40lbs, fedex said each box was 42lbs.
Comp driver is eaisily 5 lbs and the woofer is 10+

Erich will be able to give you more accurate answer but itll be close.

I think the flat pack weighs about 40lbs. The rest of the parts probably come in around 15 - 20lbs.

If you're wanting to hang those, you might want to get the taller shallow 2cuft box instead of the deeper one.

If one wanted to build a few of the new Bagby designed speakers, would it be possible to order the kit (sans flatpack) but get plans for the cabinet that could be given to a local cnc shop?

I'm all for supporting Erich and all the effort he's put into everything, but I fear I'd be doing more for UPS than for him :P Shipping a bunch of flat packs to Canada would be cost-prohibitive yet I want the ease of assembly that the cnc cabinets offer.

The cut sheets for the boxes are on each speaker page.

Shorter is better. Sealed tempesr or deltalite are my options

Thanks for that Erich!

Is there a design, or could someone easily enough work up a design, for a Kharma-8 or Fusion-8 for in-wall use that would fit the Dayton IMS-812 in-wall mounting system?

Baffle dimensions are ~ 13" x 9".

A CNC baffle from Erich to match the frame/hardware of the IMS-812 would be awesome as well!

Stephen. I've been messing around with a lot of in-wall designs lately since I moved into a new house recently. This weekend I'll be building a pair of these into my wall: http://www.diysoundgroup.com/forum/index.php?topic=37.msg267#msg267

My initial looking at this makes me think I'll be able to get it even better than that one. It's lower than your budget seems, but it'll actually be used and tested in wall. If you wanted one of those kits done in wall, Jeff or Matt might be able to simulate a reasonable cross over.

Are you building the sealed enclosure into the wall? I'd love to be able to build as IB for simplicity if at all possible. I think someone on the DIYSoundGroup forum was working on an IB in-wall Delta10 build, but I'm thinking that may be more than necessary for me.

My previous posts were for a possible future dedicated theater room. The in-walls would be for my current room... lower is definitely better in terms of budget. I have a pretty beefy AVR to power them (Onkyo NR905), so a super-high sensitivity isn't wholly necessary. That said, I like the looks of the sensitivity of the Fusion-8 better than the Kharma-8 in general and would pay the difference to get it.

Since Erich is cutting CNC baffles, one that drops right in to the Dayton IMS-812 would really make the absolute easiest possible build for anyone who knows how to use a screwdriver. Even if not, surface mounting the drivers probably wouldn't be the end of the world given the application.

Thanks again!

That was me designing the Fusion Max in-wall. It may even become a kit in the future. This will be mount flush into the wall and replace these left and right speakers.



They'll be cheaper than the Fusion 8 and on par with the Kharma 8. As far as sensitivity, they're IB so there's a solid +3db gain right there. They'll be around 92 to 93db/w/m. Only issue for your application is there's no CNC baffle available for them. Out of laziness I'll be surface mounting the parts to see how it goes. Probably cut some felt around them or something to soften any diffraction.

That would look cool, and could be done alright, but I would center the horn between the two 12/15/18 inchers of your choice. That should fix some of the problems designing the XO, as long as one would assume the listener would be dead on center with the CD and both drivers at that point would be equidistant.


how soon is "fairly?"

Do you have details on your current speakers with cone tweeters?

You can PM me if you want, to keep the thread from getting off track.

Is this JBL Everest in the same vein?

The Everest is one of the best looking systems I have ever seen. It looks very intimidating and I bet it performs very admirably.

Keep cranking,
Robert

Are you sure the baffle dimensions are that big? I can see if everything fits and get something made up. I just placed an order from PE yesterday, bummer I didn't know about these sooner or I would have ordered one.

While thinking about centers and the talks about the issues with making a small one using the SEOS 12 discussed above. Would it be dooable with a different sized horn? Something like the Denovo DW-774S. Basically make a MTM version of the Karma 8. I know nothing about desiging speakers, but it would fit in the small space of a center more eaisily vs some others if it didnt have serious tradeoffs.

Seeing JTRs new speaker is what made me think about it

I've discussed center channel set ups like that with the designers. From what I gather, even with a different waveguide, there are still issues with that set up. But I'm not sure it's a deal breaker.

I have mentioned that many other companies are doing it.......even if it's not ideal. So at some point we just have to make some designs, even if it's not the 100% ideal set up.

I'm with you on that Robert, they look stunning. I've always liked that gray baffle and contrasting veneer look JBL does.

Does anyone have a really nice photo of a finished SEOS speaker that can be used on the website? It doesn't necessarily have to be a close up shot or anything like that. But good lighting would help.

Some of you may recall that I tried hiring a "pro" to take photos for some of this stuff late last year.....because my photos aren't the best. He later asked to borrow my lights. Well, his 2 sample photos for just the waveguides weren't any better than mine, and of course I still don't have my lights or parts back yet.

I have a passive worked out for it, but don't have an inductor on hand to try it.

you can steal any of my pics from my build thread Erich, and i can get you more/higher rez if you want a cleaner background this evening
also ill still gladly help edit photos for you like we discussed a few months ago

Well, I think MTG-90 does have an MTM 2.5 way version of the Kharma 8 made up. And I have an MTM 2.5 way version of an 8" two way I've made. So they're out there in prototype land. Just a matter of, is it a good idea, or at least better than no center. Some people say running no center is fine. Some people would rather have a compromised center than no center at all.

The nice thing about the MTM 2.5 ways is you could flip them vertically for left and right as well

I have a quick question? Would there be any disadvantages to flipping the speaker cabinet so that the compression driver is on the bottom of the baffle and the driver on the top (slot port on top of the driver). This type of setup would be ideal in my case to aid in clearing the bottom of my screen, while maintaining the tweeter at ear level. Here is a sample sketchup layout. Disregard the bottom half as they were just separate bass bins me and another forum member were kicking around. I originally did the tweeter layout for a TPL-150H so it isn't scaled for the SEOS dimensions.

There isn't a problem doing that.

what same vein? About having the drivers beside each other? Yes and no, they use a midhorn to extend the horn loaded frequencies down low enough that you could put the drivers side by side, or top and bottom or whatever you want In a standard 2 way design with a single horn crossed at 1.2khz or so, this wouldn't work as well.


You can use any of the ones from my thread as well!

 

This JBL is actually a 3.5way design. One of the woofers kicks in well below woofer-midhorn XO.

Mwuuuuuuwhahahahahahahaah a storm is coming! Just placed my order for 3 Fusion 12 Tempests!!!!!!  I just want to thank all of you who have contributed to this so that someone like me can bring this level of audio into my home!  This will be my second DIY home audio project my first being a Lilmikes F20.  Once I receive the shipment from Erich I will start a separate build log for them as well as documenting in my Theatre thread in my signature!
