SEOS12/2512 Build - Page 2

Nope, never did a with/without on the same speaker, so I could be wrong. I have noticed that the ones that had roundovers seemed to disappear better, but then the way psychology works......

the way that you consider yourself both an observer and as part of the experiment in several of your reports is very rare bill...big props, very big props.

Well, who has time or energy to set up a blind test, anyway. Particularly on speakers?

Nice. Does one know what the minimum width of the box as I am wondering if I could build one for a CC, but then I would need to have the Seos sideways? I only have 12.25" on top of the stand to the wall mounted lcd. Also, where is the build plan for the box? Thanks.

Don't sideways mount the waveguide, that wont work well at all. Maybe see the Malcolm type center channel.

Thanks for the response, it is the perfect size.

I would move the woofer and waveguide together until they touch to reduce the c-c distance. Ignore this if that wasn't how the crossover was designed.

I would also make the distances equal on all three sides of the waveguide. Not that 1/10" extra on the top is is a big deal....but computer graphics make perfection look easy, nay, mandatory.

get em up at ear level, whichever height gets you there.

Ok....so you still need to get them up to ear level so either design requires a stand. My thoughts would be to make them only as tall as they need to be say 24" and get the volume by depth. The 2523 is playing high up in frequency and I'd want to reduce slap back on the cone as much as possible, heavily treating the rear of the enclosure. My design is 14.5" wide by 22" tall and 18" deep.

No estimating..........the waveguide and cd are in their own chamber,protected from enclosure pressure. Even though the SEOS is pretty thick, why take a chance. I use this really nice corrugated foam that's a full 3" thick, open cell.

That's how I've been modelling my own enclosure, two separate chambers. Couldn't you also have the waveguide and cd mounted externally? I've seen several cabinets with this type of configuration, much larger waveguides were used though. Could this be done with the seos-12?

wait till the 2nd and use the L-pad and switch the cap for lower tolerance one. dont waste time on expensive caps

for the jantzen cap dont waste your time. for the one that's out of stock get the more expensive one.

PE just started carrying Audyn caps for a good price, might check those for that missing value. BTW are the two LCR traps for impedance spikes or to smooth response bumps?

voltage doesn't matter your not planning to put 4k watts through the caps are you

I have the same dilemma. What I am trying to find out is what's a lesser compromise - all three front stage speakers aligned horizontally slightly lower than ear level or L/R are raised to the recommended level and center is set lower?
The front row in my room is approx. 12 feet from the speakers. At this distance how much of an audible difference would be between 30" and 40" (top edge of the cabinet)?

"I have the same dilemma."

can you get an acoustically transparent screen? that would solve a lot of problems.

"do you maximize the height or keep consistent?"

it seems that different folks are more or less sensitive to height variation. personally, i can't stand the center below the screen. it ruins the whole thing as i see an effect in one area and hear the sound coming from another. but if you have many seating positions around the room, a center can help get the sound near the screen without creating a lot of delay between the mains, which increases intelligibility.

it is just a problem that without some sort of weird solution like a shaded array of speakers around the screen (even that isn't ideal), you just have to choose the best tradeoff for you and your situation. i know that isn't much help.

java, ltd02,

thank you for the replies. AT screen is not really an option at this time.

i played a little with phantom center. at the MLP it sounded very good actually.
one thing i noticed is that, even when at ear level, the speakers are at the bottom part of the screen, there is still a disconnect from time to time between the video and the sound. to overcome this i had to lift the speakers much higher. but then I could not get used to the sound when listening to music....

Java,

If you are going to get the L-Pad make sure the shaft is long enough to go through the cabinet material.

I just got my SEOS 12 (350's) / Delta 12A's going this evening.....all I can say is WOW!
