This is going to be tricky in Pacific North West, our summer is over.

Yes we have had a abrupt change it looks like. Well, rain can be a good excuse to kick back and view.

I like your idea for the speaker stands. I actually have a buddy that is a furniture builder by trade, and he is trying to get in the speaker stand building business. He is building some similar stands to the ones you described. (Btw-if anyone wants some custom stands for low $ pm me and I will forward you his #)

Great job with the build.

I see that you're from the NW region, you wouldn't happen to live near or in Portland, OR would ya? I'm getting ready to pull the trigger on a set of Fusion-12 and Fusion-8 MTM, but have never seen a set in person or gotten a chance to listen to any SEOS speakers. All I have to go by is the possitive reviews I've read. If you're nearby, I'd love to have a chance to have a quick listen.

I'm in Puget Sound area so it will be 4 hour drive for you to audition them. If you are interested I can sell them to you at cost.

Getting rid of them already?

They haven't even broken in yet!
post #38 of 65
Are you going a different route or is the bass really that bad?

It should improve with break in. Also, what are those subs you are using?

In my room they are putting out good bass in 50-100hz range. I have 2 x Klipsch RW-12D but I don't really like them for music. Maybe I need to upgrade my subs instead of trying to build another set of speakers.
Statements were next on my list of speakers to build.
post #40 of 65
I would definitely consider upgrading your subs, before selling the speakers.

Started working on the speaker stands. Here is the progress so far on the center channel stand.
284570

To make the legs more stable in addition to using threaded rod I router plugs that fit into the legs and glued them to top and bottom.
284571

Even without the threaded rod connecting top and bottom they are pretty solid. The top plug has 5/16 T-nut in it so that I can screw the rod into it.

Getting close to finishing the stands.

Next on the list is to add hidden conduit inside the leg for the speak wires, paint, fill legs with sand and final assembly.

Very Nice!

Let's see them with the speakers mounted. smile.gif

Here it is, as requested:
287803

I didn't get a chance to pull the speaker cables through the hidden conduit in the stands yet.

Overall I like my new setup especially when watching action movies, they sound clean, effortless. I'm not sure whether it is a placebo effect but I think my surrounds sound much better with SEOS than they did with the matching Klipsch.
post #46 of 65
for some reason i'm having deja vu with your system and the fact that you mention some room issues.

1/4 wavelength to a boundary will get you a reflection that result in cancellation, side wall, floor, rear wall...all possible culprits for putting holes in your mid-bass.

your system looks...menacing!

congratulations on pulling it all together.

Thanks LTD02. I don't think I can do much to correct my room issues by doing room treatments. I'm already walking a thin line with my better half and consider myself lucky that she didn't ask to have the speakers removed from the living room. I might be able to sneak a bass trap behind LR but that would be it.

I'm probably just going to upgrade my dual Klipsch RW-12D setup to a dual 15" DIY sealed setup. Hopefully it will be better for music than Klipsch.
post #48 of 65
Those look awesome! I am considering the same three speakers for my next setup. I especially like the stands.
post #49 of 65
Do you have an opinion how the center speaker would sound if it were set vertically instead of horizontally? I still need a center to go with my SEOS Pure 10s, and the cabinet the Pure 10's are in might accommodate that vertical setup. It may help to know this would be due to WAF considerations, and not based on optimizing sound quality. If there is not much difference, I would go vertical. If it totally didn't work, I would place it in the usual configuration with the 46" HDTV on top of it.

I didn't do any extensive listening to Alchemy MTM in horizontal orientation. I tried it a bit and it sounded pretty close to Tempest. As far as sound quality I think it is outstanding. I started noticing a lot more of poor sound recording in TV shows that I never noticed brefore with my Klipsch. You can clearly hear when the sound engineer didn't do a good job recoding and the sound quality doesn't match the rest of the show.

Ideally you would want all three matching speakes for LCR but if you have to make compromises I think you wouldn't regregret going with MTM. One thing you have to keep in mind is that Erich doesn't have flat packs for MTM so you might need to build the box yourself.

I previously had a center MTM from Madisound which was tremendous. I gave it to my son for his new 5.1 setup, leaving me with missing center. I have read from others that all 3 LCR speakers should be "timbre matched" but the MTM paired with the SEOS Pure 10's was crystal clear especially with the spoken voice, and sounded as good as I have ever heard. I could simply replace the Madisound center with another one, but I like trying new things, and that waveguide center looked like the waveguide is actually oriented properly in the vertical position, but you can't tell anything from looking at pictures.

I hadn't gone that far in researching a new center, but yes, that would make a big difference to me. My SEOS 10 used a DIY Soundground flat pack, and I am a believer in those flat packs due to the quality and precision of the cuts.

Note: Just to be clear to others, we are using the term MTM (mid, tweeter, mid) but technically the center you have is a Mid bass, Waveguide, Mid bass. Is there nomenclature for that? Should it be called a "MWM"?

According to the site, Erich does have flat packs, but they are not listed yet (http://www.diysoundgroup.com/waveguide-speaker-kits/fusion-series-kits/fusion8-mtm-kit.html) I wonder if he would take a phone order then ship if they are not on the site? at any rate, I would bet they are coming soon. Having a flat pack for the box would be key for me as well.

I need to get photos up for the MTM flat packs. But I do have them right now.

This is a great news.I cheaped out and decided to build the boxes myself. Looking back I think I should have paid for the flat packs. It would have saved me so much time.

And money! Those flat packs are really economical for the quality of product that you get, and the VERY little amount of money they charge for them.

I am looking for the "two thumbs up" icon for your post. cool.gif

You have to define "economical". If time = money, then absolutely yes, they are a bargin. I probably spent ~15-20 hours getting the boxes built.
If you have the tools and you somewhat joy the process than DIY is cheaper. I spend around $40 on MDF for 3 speakers. Getting 2 flat packs for Tempest shipped to my door was going to cost me $216.

How are the speakers sounding? Did you end up upgrading your subs or add room treatment?
post #59 of 65

I don't think I'll be able to start working on subs until the ski season is over. Too much stuff to do with too little time. I won't be able to do much for room treatment since the speakers are sitting in the living room and it is hard to hide bulky bass traps.
I'm considering converting a one car garage (12'x19') to a dedicated theater so when it is done I should be able to go all out with room treatment on this one. I did a quick set of measurements yesterday and the dip is still there but I also notice the same dip with my subs which I didn't see previously. I need to find time to do more measurements.

I think I am going to order alchemy mtm next week . Was going to wait for tux 1099 but getting the itch to start. From all the feedback and yours as well the alchemy is a fine centre . If I get the assembled crossover , and I'm building the box , do I need anything besides wire , solder , stuffing , and binding posts ?
