Velodyne HGS-15 vs. any other sub?

[JES14]

THD at 120hz, as you stated, is still a non-issue IMO.

 

[Ilkka]

Better is relative. If you like the extra low end and the bumb around 30Hz, go buy the Sig.

SheepStar

Nope, I would like the 4x output above 30 Hz, but of course this is my opinion.

THD at 120hz, as you stated, is still a non-issue IMO.

But it tapers down to 60Hz before the bump goes away. That is pathedic for a 15inch servo sub. This whole "its at 120Hz thing, I can't hear it" is false. Its not JUST at 120Hz.

Have you checked Ed Mullen's review at Secrets? He tested the Servo V2 (110 V model) and it didn't have any additional THD at higher frequencies.

This is the Servo Sig. Different Enclosure(Which is IMO, the reason for the bump).

Ok, so would you say that V2 is better than V1. Let's forget the sig servo.

I can't say.

Need to see measurements in the same environment using the same methods and equipment

I was looking at second hand prices. They used to have at a store by me but closed out recently. I will look at the Martin Loagan's and Paradigm? Anyone have opinion on which servo feddback is better?

 

[mike c]

I have only heard the martin logan grotto (low end) - and found that it was good for music due to minimal distortion. but to match the servo in price, you can go up to the martin logan descent, triple 10" driver.

 

[dobyblue]

I'm pretty sure if you were looking at the Martin Logan Descent you wouldn't look back - I can't seem to find a bad word about it.

I'm looking forward to giving the Depth (US$1,700) a listen next week-end. I'm considering the Paradigm Seismic 12 or Martin Logan Depth at the moment.

I listened to both the Depth and the Descent in the same room, A\B'd and the Descent was beyond real. I have a large room and even I could not imagine having a home big enough to need the Descent. I think it could be more detrimental, than helpful if you have a small or medium sized room.

I think you will be entirely happy with the Depth which was over the top. I have considered adding it to my existing home theater, it was that impressive. My only knock is that it is fairly plain looking. I think you will come to the same conclusion but keep us posted. I am interested to see if you think the Paradigm can compete.

 

[RMK!]

excetara2,

Opinions are like...well you know the saying .

The Velo you inquired about originally is a great subwoofer. The excellent Audioholics review should provide you all you need to know about the HGS-15X. Although I have not heard the HGS-15X, I had an HGS-12II and really liked that little sub, but it was too small for my large space and my ever increasing appetite for more LFE. There are a lot of good options at this price point and while hasty decisions can be bad, analysis paralysis is no fun.

I am an advocate of buying used until you get a good feel for want/need for your type of usage (music vs. HT) and the room where it will live. Then you can go whole hog and buy the shiny new showroom model.

That's awesome thanks for the input.
I love Paradigm but I've developed a very keen interest in the ML Depth over the last 6 months. I don't have a ton of money to spend on my audio, but I have a Pioneer DV45a DVD-Audio/SACD player and have to admit that as time goes on my hi-rez audio collection is getting bigger and bigger. It's time to consider a good sub and I've had my eye on the Seismic 12 for some time, but I can't help but think that perhaps the Depth would do the advanced resolution audio more service than the S12.
I'll definitely post after I hear the Depth. There's no question the Seismic 12 would be a great addition to anyone's HT for movies, but there's no worse feeling than spending a lot of money on something and then sitting there wondering if you bought the right product you know?
Audio.....where does it end?
One thing I'd like to ask is, how would one position the Depth?
Here's a link to a pic of my current HT set-up, with the sub in the right-hand corner.
Would the Depth go well over there with it's Balanced Force array?

I think any of the subs you have narrowed your list down to will be more than adequate for the size room you have. As far as placement, I would suggest the steps outlined on the Audioholics website for setup.

http://www.audioholics.com/techtips/setup/index.php

I also suggest you read a paper(s) written by Dr. Toole. It is not in this paper, I do not think but his recommendation was to start in the middle of any of the four walls in the room, and not the corner, when using one or two subwoofers. Since any of the subs you mentioned will have more than enough power, corner reinforcement is probably not necessary IMO. A cleaner bass may be possible moving the sub away from the walls a minimum distance based on your crossover setting in the receiver setup. I found the advice very helpful and accurate.

http://www.infinitysystems.com/homeaudio/technology/whitepapers/audio_art_science.pdf

It seems Harman has removed their white papers from their website, or at least moved them so they are now hard to find. Always a good read.

Good Luck and let us know what winds up being the best sub position for your room\home.

I heard the Ultracube 10 and I was less than impressed. It sounded really slow and the driver was bottoming out before it could hit any real dB's (and this was in a small room [12 by 10]). If the sesmic series takes anything from the Ultracube (which it appears to) you may not like it.

Edit: Heres some measurements.

One thing I'd like to ask is, how would one position the Depth?

If you get a Velodyne Digital Drive sub, the sub will show you exactly where the best spot is and then allow you to accurately adjust it to give you the best possible response for your placement. Couple that with the worlds first digital servo control system(16,000 times per second) and a world class 1250WRMS amp and driver, along with free software upgrades to keep it up to date and improve it over time(can't say that about any other sub), with, at least the DD15 or DD18, you will find that you have lost that nagging upgrade bug, I know I have (unless you want two of them )

Have a listen to this interview with Bruce Hall(President of Velodyne Acoustics)

cheers

Uhh, he was asking about the depth, the Martin Logan sub.

Check the website, they usually have a picture in the manual. BUT, the usual sub locations will do. Its all the same thing. Just have the plate amp facing the wall its against.

The DD-10 seems to be around a similar list price as the Seismic-12 and Depth.
It's roughly CDN$500 more, is it worth auditioning that as well?

Well I finally did get my sub - I got a new black Paradigm Servo 15 v2 for CDN$1750 during Christmas Week sales. I hooked it up on the 24th.

I have certainly taken my time to decide on the right sub and I am absolutely thrilled with the performance of this sub. Everything I've listened to on it has made me laugh with joy.

Thanks to everyone for their input - I think I made the perfect choice.

 

[annunaki]

Maybe not a brick wall, but set at 80hz anything at 120hz should be speakers only. You would have to be inches from the sub to hear any distortion, a non issue.

Actually, if test tones were used to output 100db at all frequencies (with an 80 hz crossover point) and a 12 db/oct slope is used the signal would still be at 94db at 120hz.

If a 24db oct slope is used (@80hz) it is still only -12db below the fundamental signal or 88db at 120hz.

If distortion is at an audible 10% it could probably still be heard at 120hz.
