    Chaps,

    Time has come to make that sub purchase. I am completely sold on the Velodyne series, silently following the power buy threads for many weeks. I had made up my mind to buy the CHT-15, even so far as mailing eric, however I am now not so sure.

    Has anyone heard back-to-back or otherwise each of these three monsters and can give a definitive opinion of the differences between the beasts. Is the HGS-15 worth a grand and a bit more than the CHT-15 and then if one sways to the expensive, is the difference between that and the almighty HGS-18 worth digging just that bit deeper for the extra few hundred ?

    I know that all posters are happy with their respective purchases, and I have yet to read A SINGLE disgruntled thread, but has anyone heard all of these beauties in action ?

    My system is reasonable high endish - TAG process and amplification, and ProAc front/centre speakers. I want something MEAN :mad:

    Any opinions ?

    Regards.

    I think that there's only one person who can answer that as I doubt whether anyone else has heard both the HGS and CHT series.

    With a Tag setup I'd personally get the best sub from that list, namely the HGS18. It's hard to describe how good it actually is without sounding arrogant. I considered £2155 a veritable bargain when I got mine and tweaked it, it will totally transform your overall sound. If you live near and fancy a demo you're more than welcome.

    The Velodyne HGS-18 has been described by John E Johnson Jr as a product by which all others are judged. Its simply the best. Subwoofers are supposed to play a "supporting role" by underpinning satellites.
    The HGS-18, can underpin an apartment block let alone a few sats.

    The HGS-15, its THX Ultra2 spec stablemate is almost up their with its bigger brother. The composure of this sub is nothing short of stunning.
    The CHT-15 is IMO a bargain. The M&K 150 for example is more than twice the price and comes nowhere near in terms of performance.

    I have lived with all three in my demo room. The CHT-15 for a few days (ran it in for Jase), the HGS-15 for a few weeks and the HGS-18 as my reference subwoofer.

    just woundering if the HGS15 would be more music due to it smaller driver. I have been on audioreview.com, and alot of people comment on it being "Slow".

    Firstly, there are a lot of nutters on audioreview.com - you get 19 people saying something is wonderful and then 1 saying that it's just about the worst thing they have ever heard! The trouble is that most, if not all, of the 19 actually own the equipment in question and so they are not necessarily going to say it's anything other than fantastic.

    Secondly, with the likes of the HGS15 and HGS18 (and the Paradigm Servo 15 for that matter), the size of the driver is pretty much irrelevant because of the Servo control engineering they utilise (which keeps the driver in check and minimises distortion).

    In the case of the HGS15/18, distortion is kept to 0.5% or lower which is a staggering result - basically, it means that they give almost totally accurate bass - not fast, not slow just plain accurate and this is all that is required - remember, there is little or no audiophile quality to sub 80Hz bass - it is all about accuracy - this is why tonal matching is irrelevant with subwoofers.

    Does this all mean that the people on audioreview cannot have heard "slow bass" with HGS15/18's? No, because if the integration between the subwoofer and the main speakers is incorrect then it can sound like slow bass - what's at fault, however, is the integration of the subwoofer, not the subwoofer itself.

    Matt.

    Another excellent post by Matt. :)

    If you can afford it and the size is fine this is a no brainer, just buy an HGS 18 off Eric. It is the best commercial sub I have found. If someone tells you 'negative' things about it performance just assume they are speaking crap and they know nothing about subs. It's performance is monumental.

    Be very wary of audioreview, a club for people to justify often wrong purchases from very limited experiences. ;)

    As in buyer beware.

    Yes the HGS-18 is a masterpiece, and the HGS-15 should also be seriously considered. However if you're room has resonances anywhere below 30Hz where most subs can't reach, these subs will find them.

    I'm not trying to put you off the Velodynes, as they are seriously good value for money. Just bear in mind that you may wind up doing some work on room acoustics. Thankfully if you buy from Uncle Eric, he'll be able to point you in the right direction.

    Thanks Mark,
    All good points. Another aspect of this is that subs in this class find rattles and creaks that folks never knew they had. For this reason, during my Home Theatre installs, I like to run a full frequency sweep in order to identify these rattles and rectify them before install completion.

    Nothing worse than buzzing picture frames, door handles that rattle etc etc. You'd be surprised how many installation companies omit this very important procedure.

    I'd dread to think what one of those mofos would be like in my room :eek: I find my Stygian bad enough, my room acoustics are crap though, have a wardrobe that shakes at around the 35Hz mark! I have also noticed alot of movement in the window panes at certain frequencies!

    Well I haven't rectified my room as Uncle Eric has and sure enough everything that isn't solid rattles, a mirror screwed to the door, the door handle, the rear speakers, coins on the PC desk, me :eek:

    The HGS18 has the ability to scare, I'm serious, it will make you feel things that you've never felt before. Watch the DTS version of The Haunting at reference level and you'll think the whole room is on a transducer, this film transcends from viewing to "active viewing" :).

    It's almost masochistic to even think of using a pair of these, I'm quite certain that a pair of these at loud volumes could do actual damage in my room................cool :devil:

    Here is a piccy of the volume setting I use (the processor is set to -2 on the Sub level) and that setting is more than enough :eek:

    Dual Servo15s have been reported to have cracked a concrete lintel at a teenagers party when his parents were away! These things need to be treated with 'repect' :D

    What in the frilly eck is that cable magking :eek:

    I assume it's a single phone to dual phono, the feeling on this forum is that the only advantage for that connection is the ability of the sub to detect signals easier for auto switch on................but the HGS has a permanent On switch so doesn't need this.

    Please enlighten me as to what it is and why you use it, thanks.

    The cable is a Monster M351 SWHT, THX sertified sub cable.
    It comes with a Y-splitter and a short cable so you can use both inputs.
    I guess i don't really need it, but i connected it like this when i got it on New Years Eve and have'nt thought much about it.:blush:

    I use the On option and shut it off by the remote when i don't use it (Can't stand the "hissing" when i'm trying to sleep, it's 1m from my bed).
    Do you think i'll get better sound if i don't use it?

    Oh, and i have the volume on my amp to -7db.

    Using the Y Splitter won't hurt, nice cable btw, I have 2 x Monster Scart cables at £120 and they are fantastic. I currently use an IXOS Gamma 1141 for my HGS, does anyone know if a more expensive cable will yield better results?

    I would say, as long as the cable is well sheilded and has some quality about it (termination/plugs) that's all that's needed. :) I don't think a more expensive cable than the one you already use will give better results.

    Thankyou each and everyone of you for your considered and amusing replys.

    I have decided to get the HGS-15 which will give me the impact I am looking for, but fit within the constraints of my living environment and budget.

    Eric has been mailed so I look forward to his reply.

    Thankyou all again.

    Regards,
    Steve.

    Steve,

    A good choice. You'll be over the moon with the HGS-15. I've been very pleased with mine.

    Rob,

    Perhaps you can tell me this plse. I have started another thread on the amp board because I am considering replacing my 100x5R with the Bryston 9B. I prefer my music a bit more weighty and bass-ier than what I am getting.

    Did you find that with the addition of the HGS-15, your music listening took on a bit more weight and did it integrate well for you ? I am hoping that with the addition of a sub, the concerns I have about my weedy amp will be lost in a fuller belly of bass !

    Thanks again,
    Steve.

    P.S. Cheque will reach eric next week (post pay day :blush: ) so I will post again to tell you how I am getting on with it. . . .

    As the HGS15 is very similar in performance to the HGS18 I'll answer this one if I may.

    Forget everything you've ever heard about large drivers being rubbish for music, the HGS15/18 utilise the Servo technology to the max, when set up properly it will totally change your music. I listen to everything from Basement Jaxx to Linkin park to Eminem to Vanessa Mae and the HGS is a perfect addition. With the handy remote control you can tailor just the right amount of bass depending on how the piece was recorded.

    Just wait till you get your hands on the HGS15, you'll be sat in your chair listening to material with a silly grin on your face. I doubt I'll ever make a purchase in the future that will so profoundly change my enjoyment of movies/music, I'm still excited now and I've had the sub for 3 months :blush:

    The HGS-18 is fantastic for music & anyone who tells you otherwise is quite possibly wrong.
    I have seen (via posts in here) that some people turn their sub off when listening to music..

    Bad sub or incorrect positioning, or both?

    I'd be happy if i had to pay £3000.00 for it

    @ Uncle Eric's prices, you'd better saw his arm off for one.

    I'm afraid that I just can't agree with the above statement - not all of it anyway - take out the words "quite" and "possibly" and you will have my full support.

    Alright,

    Enough enough. . . . .
    Forget it, overdraft has been arranged.

    Eric - the cheque and covering letter are on the way.
    Apocalypse - the invoice for the overdraft charge is on the way . . . . :clown:

    Your enthusiasms have got me wondering just what I have let myself in for I cannot wait any longer !!

    Once received, I will be sure to take some time to set it up, run in, and then give my feedback to you all. Of all my AV purchases I have to admit that this one is giving me the biggest anticipation. . . :)

    Cheers,
    Steve.

    *SPOLIER ALERT FOR "THE HAUNTING"*

    You owe it to yourself to watch either Titan AE or The Haunting (both R1 DTS versions) when the HGS15 arrives, I challenge you to keep a straight face on the Haunting at 1hr 14mins and 35 seconds into the film, the eyes open and Nell says "God it's coming for me" then you get this almighty wallop from the sub that is unlike anything I've ever felt/heard from a sub :eek:

    Other favourites of mine for sheer bass quality are Brotherhood Of The Wolf (R1) and Blade II (R1).

    Musically you should take a look at www.telarc.com as they specialise in low frequency material. I've got about 6 discs from them and they are indeed low, infact most of them go lower than 10Hz which is the very limit of the HGS18. I took this pic of the warning on one of the DTS CDs here :eek: :eek: :)

    Adam why have you changed your name?


    My HGS18 is really singing now I have taken a bit of time to position it correctly and run it in. The sub is awsome and I now know what real sub base is. I had two REL storms before this and they are just blown away. I now realise that what I thought was sub base was just distortion and vibration.

    I have yet to try it on the haunting.
