It depends. what do you consider low frequencies? The eD would most likely have an output advantage from 5-11hz and 20-80hz. The ultra would have an output advantage in the 12-18 hz range(maybe, depends upon room). Sound quality would depend upon you. Some will like the ultra and others would like the eD. I am just guessing here.

ED A7S 450 vs PB13 Ultra
Hi there,
How does the the ED A7S 450 compare to the PB Ultra in terms of spl output, low frequencies and bass quality.
cheers

Wouldn't a fairer comparison be two A7S subs and a PB13 ultra? That is the cost equivalence. While I'd love to have a PB13, the thought of owning two A7S subs is sexually arousing.
Yeh, that's why I got two!

I'd think the advantage would lie in the 50hz - 80hz range. Advantages in the deeper hz area would favor the Ultra until you get below tuning. It would depend on room gain and outboard eq of course. That said, they both get pretty damned loud.

I don't own the eD or ultra but I did have the plus/2 which is supposed to be louder than the ultra above 25 hz(dual 12's with 900 watts). My sonos are similar to the eD, just a little bigger and the plus/2 can not match the one sono above 25 hz. That is in my room though and other rooms may vary.
bsoko2, how do those two ed's perform as far as out put an SQ? because I was thinking of going with a submersive but if two ed A7s could somewhat compare to one submersive then I think I would happy with that. let me know your thoughts.
Can't answer as I have not heard the Submersive. But from what I've been reading on the forums, the Submersive has both Output and SQ with little distortion. It is really hard for any sub to do this and Mark has came close to it as what I have been reading. If I had it all to do over again, it would be Mark Seaton all the way, speakers and subs.

I've got dual Ultras, but started with a single. I've not heard an eD, but they've got a good following as well - just not my cup of tea regarding their finish. The Ultra sub is something special and I'm constantly discovering new sub 20Hz information on DVD's (no bluray yet). I got a second since I've got some serious nulls going on with a wide range of seating positions that I didn't want anyone suffering from a lack of flat response. Plus I used to run dual Outlaws and when my wife asked why I needed duals before but not now I presumed that was permission to get the second.
You won't really appreciate your subs until you go with BluRay. Getting a good balance between your speakers and sub(s) using BluRay is harder to accomplish then with SD DVD.

I don't want to change the subject but what about the DIY kit ED sells?
Looks like dual 13"'s with a 1200 watt amp.
Anybody ever build one of these?
It is sealed so it should go way low.
For a grand, it's sparked my interest.

That sub should be killer.
bsoko2,
are you pleased with the A7s's performance in HT and in Music?

Why is that? The test tones are the same and so is the procedure to do speaker balancing including the sub.

True, test tones are output via the reciever or the test tone dvd. DTS Master Hd material is a real killer on mains and center with its highs and lows. Unless you have new speakers or high end speakers to handle the new codex's, vintage speakers really suffer with it unless you have the crossovers upgraded. True HD is not so bad and standard DVD audio is a walk in the park compared to DTS Master HD. I have Polk SDS SRS 2.3's for my mains and some HD audio is too bright and some BluRay movies with the DTS Master I will watch and listen to with THX Select 2 to handle the highs and lows of the audio. Now that I have amped out all my speakers from my Pio "94 reciever, that has helped with the taming of the audio tones in the DTS Master HD in BluRay. I found that external amps really help with thier added wattage in the audio channel.

For HT the 450's have the output that you look for but is limited on the bottom end unless you really do your homework with the setup via an EQ of the LFE. I have the Anti Mode 8033 and have not really done REW as yet on my room. I plan to do this in August when I go on vacation for two weeks. Hell, I'm 66 and don't take well to new tech things right away so I need time to sort it all out (don't know how I got this far with everything I have today with the HT setup). For music, I really miss the HSU 3.3's SQ and I wish that HSU would really address this with a new sub line that can deliver the best of both SQ and slam (output) in a sealed sub. I haven't heard the ULS15 and reading some of the forums it falls short on ouput but excells in a flat curve with SQ.

Do you mean that THX rolls off the high frequencies so you don't put as much demand on your speakers? I haven't messed with THX for a while, I didn't know THX rolls off low frequencies.
Or did you mean something entirely different with your statement about using THX for certain material?

From what I undertstand of THX that it filters out the highs and lows for a even balance of all audio channels across the board. If you try THX with any movie format you will find that you can up your volume a few numbers on the dial from where you usually listen at and it will increase your bass. THX has no audio filter (audio parameters adjustments) that can be indivually adjusted like DTS or DD so it sets a level between the lows and highs. You won't loose any bass with THX just some audio lows and highs (it is like it compresses the peaks and valleys of the audio channels). I hope that I make sense of this to you.

Thank you for the clarification. I guess I listened to too much loud music. I need all the high frequencies I can get.
One thing is for sure. I am not one of those individuals who is afraid to use any available settings to get the best sound to their ears.
Some people wouldn't dream of using something as simple as a tone control. If I was a golden ear that would be something entirely different.
