Most woofers do weigh that much or more, but I've been looking for light woofers lately, and the Deltalite 2512 weighs just 5.1 pounds. It is the best output to weight ratio that I've found yet.

Wish it could be easier to order a sealed Tempest. Sent an email to Eric a couple days ago asking for a sealed front baffle swap, I know hes busy and all, I'm just impatient. I want my three Tempests too!

post #6903 of 9844
I guess ignorance is bliss but what would the difference be going sealed vs not on the tempests? I just know that I like the way the three ports look!

I might have missed your email. Did you want the same size baffle, just no ports? Or did you want a shorter baffle with no ports? When you order, there's a place to leave a message. You can just write it up there. If I can't get it done, I'll send you a message back.

The Tempest works ok in a small sealed cabinet of 1 cu ft. The only problem with this type of setup is the F3 is 105hz so a subwoofer is definitely needed and has to be crossed at around 100hz to a subwoofer. I wanted something small/slim and at least a 12" woofer to go with my quad subs. With the ported version it digs a lot deeper, 37hz. These could be run full range for music and crossed over to a sub lower like 60/80hz.

I would like the 14.5 x21" sealed baffle, the same as the Deltalite. I'll leave a message in my order thanks.

 

EDIT: Just bought the 3 Tempest kits and left you a message in the order.

Thanks, that makes sense. I ordered the Tempests because they seemed like they had the best specs in my price range and they play low and I like the look. I have never had a speaker that could be considered "Full Range" and would like to try how it sounds for listening to music although I am sure most of the time it will be crossed with my F20. Also I keep reading about the "mid bass punch" of the Tempests and that is something I have always felt was lacking in all my audio setups. Cant wait to hear the impact of these on my front stage!

Hi Eric, I sent you an email but thought it might be better to ask here (so maybe you don't have to keep answering the same Q multiple times).
Do you have an baffles for the Big Mal?
If yes, should I order the Malcom and say "make it a Big Mal in the comments section. It's a bigger baffle so I'm guessing it'll cost a bit more and shipping will be a bit more (to 46140). Just let me know.
Thanks,
Gunther

The cut-out dimensions are 13" x 9", and from the looks of the pictures there is maybe a 1/8" lip that the baffle butts up against... so the total baffle dimension might be ~ 13.25 x 9.25. One main consideration would be not overlapping any of the mounting screw holes.

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.

Any info on the Jack of All Trades 8 in an in-wall application? I'm thinking this may be a really interesting for budget in-wall mains behind an ST screen. Not sure if they would fit on the Dayton IMS baffle mentioned above given the horn width, but that's not necessarily a must. If the IB crossover is similar to the sealed in cost, these would come out to around $400 for three channels... quite respectable. I'm assuming the IB could likely be crossed over with a sub at 80hz easily as well, maybe lower?

Wondering if there are any current kits that are approx 6-7 inches or less in depth that would mate well to the Fusion Tempests as LCR? If not, any thoughts on how a set of Klipsch in-walls might work?

A similar question...I was thinking about the Klipsch RS42 II for a surround but how would they work with SEOS speakers up front? Some people say that Klipsch speakers are a little bright and that is something I don't want.

post #6911 of 9844
I've got my jack of all trades in wall playing right now. They have an edge over the boxes version but xo is a few bucks more. Literally like $3 more. Ill put together info on it in a few days after I've logged some listening time.
post #6912 of 9844
I'm looking for opinions on surrounds for HT. Particularly folks using SEOS speakers for surrounds. I really am concerned with directionality for my surround choices. I currently use vertical MTMs with a 1" silk dome and 5.25" woofers for surrounds and at times I feel they are too directional. My room is pretty narrow so that is another concern(only 14' wide). This puts listener ears 6-8' from the speaker maxiumum.

I have the parts for my LCR builds(SEOS over 12" Eminence) build but am already looking ahead to the surrounds.

Has anyone considered a high efficiency dipole/bipole for surrounds?

Are monopole/dipole considered obsolete?

Another concern for me is I will have two rows of seating and this stretches the beam width of the SEOS. My listener ears will be about +/- 37degrees from on on-axis. I know this is still in the "zone" but just wanted to discuss.
post #6913 of 9844
Your furthest listening distance is 7' (14' wide room) so we're in a similar situation and I've been wondering what to do also. I have no surrounds ever since I moved last summer. Because the listening distance is low and you want wide dispersion, I'd personally go with a neo SB29 tweeter crossed to a 5.25 woofer. I think that's how I'll end up going. It could cross pretty low. And if that's not enough output then make it a three way with an 4" mid and 8" woofer. Keep all three drivers in there omni bands. Or maybe even this guy here: http://www.zaphaudio.com/SR71.html That stays pretty even off axis quite a ways out and there's a reduced baffle step compensation version.

I will probably have to mount mine in my ceiling or on weird wedges on the wall behind me. I'm really stuck also.

I've been using these guys for surrounds over the past year. No complaints, but I am not an audiophile.

Ive been thinking about using these, how do they match up with your main speakers? I've been reading that there is a difference in sound between a compression driver and dome tweeter. I'm also not an audiophile so I'm basically looking for something that sounds good and not a huge difference in sound. Wayne recommends the one Pi with his speakers so they must sound good!

I use and like B&C 8CX21 coaxes; in fact I just bought four more for my 11.1 system.

Addresses the listener/integration distance issue, 94 dB efficiency, and work in .5 cu ft ported boxes.

F3 is highesh though, ~100 Hz IIRC; doesn't bother me.
post #6917 of 9844
Any of the 8" EOS models would work great.

I've been having the same concerns lately. I've discussed it with Parham. His opinion is that you need a 180 degree waveguide for surrounds - in other words a baffle mounted tweeter. I'll have a chance to listen to a set of Jack of All Trades soon and hopefully that'll give some real world experience.
post #6919 of 9844
I've been happily using all monopole waveguide/CD speakers for side and rear surrounds (CHT PRO-10s) for over a year, no complaints.

Agree...very wide dispersion surrounds is my preference as well.

I'm thinking about using these as surrounds, mounted in the back corners of my room.

I got the last of my speaker components from DIY Sound Group today.  When my theater is done, I will have 3 Fusion 12 Tempest speakers for the left/center/right.  I will be using 4 Fusion 8 Alchemy speakers for my surrounds and I picked up two sub flat packs for my 15" Titanic subs.

 

While it has been said many times what a great service Erich has done for the hobby by taking the time to offer these kits/components, I also wanted to point out the care that Erich puts into each order.  Yes, he answers tons of questions via email and makes sure everything is carefully tracked on your order, but I was really amazed at how well my orders were packed.  Some serious thought went into boxing these parts.  This isn't a part time ebay seller tossing some parts in a box.  He carefully bundles/straps the pieces and packs them with various types of foam to ensure everything arrives in perfect condition.

 

I know this doesn't have much to do with building speakers, but it is one more thing to ease our minds when sending our money to someone and hoping everything arrives intact.

 

Thanks for everything Erich!

+1 Big props to Erich.

180 degree surrounds. ... What about two 90degree waveguides toed out ±45 degrees from center? Then vertical is still narrow with less horizontal beaming than with domes. Assuming the waveguides work wedged together like that. Maybe a bit pricey for a surround though.

Wouldn't you get combing doing that Bill? Or am I not understanding what you mean.

Try 'em firing up as well as straight out.

I'm also in the wide-dispersion camp for surrounds. In practice, for me at least, that means concentric drivers firing up. That's always seemed to work better than any other alternative. I haven't tried a narrow line array/CBT though. I suspect that's the next area to experiment with. Toole looks favorably on the idea in Sound Reproduction, but to my recollection his comments are more grounded in theory than practice.
post #6927 of 9844
Sounds like there is a lot of demand for wide dispersion high efficiency surround designs.

I would help out if a designer wanted to tackle it. I really would like to see a high efficiency dipole/bipole, i dont think thats been done yet in DIY!

Anyone?
post #6928 of 9844
I really don't see the advantage of a dipole/bipole over a monopole for surrounds? I've never understood how they even came to be. If ever I can avoid two sound sources above 2khz I will (including a cross over). And a 90db/w monopole with a 180d dispersion pattern is easily attainable. Even 93db/2.83V/m is easy to get. The Kef coaxial idea is excellent, as long as effeciency doesn't have to be high.

What kind of effeciency were you hoping for?
post #6929 of 9844
Surround novice here, but I'm curious what the use case is for wide dispersion surround speakers - I would expect ~90 degree SEOS speakers to be a darned near perfect solution if you point them right at the head of the back row viewer furthest away across the room.
post #6930 of 9844
People who want an ambient sound rather than a pin point sound. Also, because of the oblique angles across all the seating positions, point source / wide dispersion sound covers the listening area better. We've hacked this one out a few times on this forums iirc. Seems like half and half. I've taken the position that either works if implemented correctly. Most of the time people with moster waveguide surrounds go on about how great it is, but their listening distance is well over 10 ft. Then someone like NicksHitachi has a narrow room and they prefer (rightfully) the wide coverage.
