My main concerns for surrounds are sensitivity mis-match and compression of my current speakers. My current surrounds are much lower sensitivity(89db). However I'm expecting them to noticeably run out of gas and for the sound field to collapse to the front where the SEOSs reside. rolleyes.gif

From behind and off axis I'm not sure that tone timber matching would be a deal breaker for me, although I do concede that it is ideal for all speakers to be identical, period.

Well the biggest issue isn't them running out of gas; it's crippling the mains. If you calibrate all of them even, you will just be backing down your mains to be equal with the surrounds.

I haven't really noticed any "distracting" timbre issues with my QS8's and the SEOS up front.

I'm not sure my surrounds have ever been asked to do 90db even

Which would mean never have your mains (if properly calibrated).
post #7627 of 9857
Huh? My mains have definitely hit peak SPLs over 100db at the listening position.

Show me a source material with surround content as loud as -10 to -5dbfs. Most surround mixers already mix well-calibrated surrounds to 3db lower than they would be if they were mains because they fire directly into ears, and even then they never put the big dynamic sequences on surrounds.

I'm not saying that it's a bad idea to build for dynamic surrounds, but I am saying that I have never come across such content.

Only one that I can think of is war of the worlds, when tom cruise and dakota are watching the lightning storm. There is a scene where the surrounds have a pretty loud effect. I don't know how loud it is but its the loudest I've heard from my surrounds.

I've been around, haha. Mostly just lurking. Over the last month I got a cool chance to review some nice speakers, which took up some of my time. It was pretty refreshing from my perspective, because until these, all the real critical listening I've ever done has been towards similarily voiced speakers.

My SEOS Project is currently underway too, in the box construction stage, but it's been put on hold as much of my free time has been devoted to preparations for my sister's wedding. I can say that one of two baffles is glued together to 1.75" thick, the sides, back, and top/bottom are all cut, and one of two slot vents is glued together. Gotta cut up the bracing still, which for the time being is on hold. Once one speaker is built it will be designed and voiced in mono and then the second one will follow.

Thats what I mean by compression although I might not be describing it correctly. I calibrate spl at like 75-80db for all speakers flat. However as I turn up the volume the lower sensitivity speakers exhibit "compression" and "run out of gas" and the SEOSs keep going. At higher volumes this would bias the SPL balance towards the front. Maybe compression is not the correct word? IDK biggrin.gif

I know for sure from measurements that the conventional MTM with dome tweeters the top end begins to get rolled off when they reach their limits. Distortion is pretty high by this point also. They will absolutely not track as linear in power response or flat FR as the SEOSs based on my experience measuring both. How this affects the sound field in everyone's room is prob different by application.

Thats encouraging that you like the Axioms! Like I said before, I hope to be able to keep my lower sensitivity speakers in place for surrounds(for a while wink.gif ) and I don't expect timber/tone to cause any major concern for me either.

i dont think that will be the case. the mains are usually mixed much louder than the surounds. also, the material going to the surrounds is usually higher frequency stuff. if anything, the surrounds would just clip and/or distort not hold the mains back

So I noticed the Fusion-8 Alchemy MTM is in stock now, when will the frequency response, impedance, power handling, and sensitivity be updated?

If audyssey turns it way down then the gain is too high on the amp.

Just trying to figure out a budget and wanted to know which CD's are available to purchase Erich?

It looks like the BA and the 350 yes?

And how do I get a quote on the shipping to Australia?
post #7636 of 9857
The CD's right now are the 105, 205, 350, and 360. Shipping to Australia is quite expensive. The cheapest way is US Postal Service, but it's still ridiculous.
post #7637 of 9857
Well I was interested in the 360 and BA. But on the website it said the 360 was reserved for those buying WG's. How big of a box would it be for a pair of 360's?

The only other option I have here is 18 Sound and Beyma CD's. I know it might be close in price with the 360 including shipping but I wanted to ask. I was hoping to start on a SH soon. At least I can model what I hope I can buy soon is all.
post #7638 of 9857
Hey Erich, any update on the plastic SEOS 15's? Just curious how the GB is going so far and what the timeframe is shaping up to be.

I need (want) to order some more stuff from you and if I could order and ship it all at once it would probably work out better. Also, I am looking for some custom baffles to be made for the SEOS15 and the TD15. Is this something that I can get through you as well?

Thank you.

Brian

Things are taking a little longer this time around for some reason. I'm suppose to have samples in about a week. Then I give the go ahead and should have them about 5 weeks later.

There will be baffles available.

chrapladm, the box to ship the compression drivers wouldn't be very big. But I do put a decent amount of foam around everything before shipping. I'm guessing 10" x 10" x 8".
post #7640 of 9857
10x10x8 is for which CD? And can a pair fit in that box? And how much is the weight?

Will there be larger flat packs as well (3ft^3)?
post #7642 of 9857
For those with the SEOS-24 and 1.4" entrance, here's a bracket that will make life easier: http://www.ebay.com/itm/Horn-and-Driver-Support-Bracket-for-1-4-inch-Exit-/380451199667?pt=US_Speaker_Mounts_Stands&hash=item5894a89ab3 The seller is Bob Crites: http://myworld.ebay.com/bobcrites?_trksid=p2047675.l2559

With the bracket in place, the SEOS-24 is heavier than a BMS coaxial compression driver. I plan on making a shelf for the horn and bracket that the outside lip of the SEOS-24 will rest on, as well as the bracket above. This will keep things stable and take stress off the SEOS's neck.

Erich, would it be possible to get a quote for shipping to Toronto Canada for say the Alchemy MTM 8 and two of the Alpha 8 Minions? I assume these would match decently?

Also, how large are the shipping boxes for these and how heavy? Alternative would be to send them to my parents in FL.

Thx
post #7644 of 9857
Does anyone know what port tubes are used with the 2 cu ft flatpacks? They are the same as the Tempest design.
I need to purchase 12 of them and I cannot find the exact ones to use. I am sure Parts Express has them I just don't know which port tubes are recommended.
Thanks
Chris
post #7645 of 9857
The ports come with the kit. Did you order just a box or a baffle and need matching ports? Or are you doing a different design and need a baffle cut with the ports?

I'm still trying to figure out how to calculate shipping to other countries. Shipping through my FedEx account is too high. Right now the problem is that I have to package up an order, get the weight, then take it to the US Post Office. Then contact the person and let them know how much it will cost to ship. They say 'No Thanks', then I just lost 1-2 hours packaging up their stuff and getting a shipping price........only to unpack everything.

There are a decent number of people that use forwarding companies to ship their stuff to them. They must be located all along the border. There's also a company called Jet Carrier in New Jersey that must be reasonably priced because there are a lot of people from Norway and other countries that use them.....even to ship 65lb 4 cuft flat packs.

If anyone knows a good way to set up shipping to other countries, I'll do it.
post #7647 of 9857
I think the USPS said 10x10x8" 8lbs box would be about 100 roughly to ship. Seems high but I expect everything from the USA to me to be about 100-175 for shipping. Still think I will order some 360's soon when the group buy is over for the SEOS WG. 150 each for the 360 is still a good value to me.

I bought 4 x 2 cu ft flatpacks with the baffle cutout for the TD12M. I received them a couple weeks ago. I need 12 total port tubes that fit the 3 port design
Thanks

just ship it to the border and pick it up. https://www.kinek.com/

storage central in buffalo only charges 5 bucks.

Thanks for the update. Are there any additional GB orders to Poland planned? I may be interested in ordering some SEOS 18's. Thank you!
