Axiom Home Page Forums General Discussion Advice from Axiom Owners Subs - SVS vs Axiom

In reply to:

If I buy a 500w plate amp for say $250 (cheap!), a driver for $200, and spent $50 for enclosure material, I would have to build it in about 4 hrs to keep it under what I paid for the SVS. It would probably take ME 30 or 40 hours to build it, making it way too expensive for me.

Sounds like my DIY rig, except my amp was a slightly cheaper and slightly lower powered, but with a considerably more expensive driver, and the enclosure was about $150 to have done for me based on specs given. [I cannot make a good box - lol - I've failed too many times to get the extension right. Tuned ports are HARD to do.]

Hey Curtis..
Ok, gonna jump in here a bit.. I was over at Hsu last week, and listened to both the box type and tube type subs.. Now, this may only occur at higher levels, but the tube style seems to play smoother.. Dr Hsu says this is due to the longer port..
Sounded good to me ? Both the reasoning and the actual sound.. :>

Pretty sound reasoning.. Hard to beat a mass produced product, if it's done right.. And it seems these top sub companies are doing just that..

What I'm getting at is that there is more to a sub than loud, low, and distortion.

Just like speakers with similar numbers and freq curves. Get them into a room and they sound different.

After hearing my VTF-3 and a 20-39PC+ together in the same room. Both great subs, but they sound different.

Hey Mikey,

I know Hsu's TN1220HO tube sounds different than the VTF-3....definitely tighter and cleaner.

Also remember, the TN1220 tube design is different than SVS tube design.

Did you buy one?

curtis, sounds like you're discussing women; are you on the correct board??

I just read my last post...I meant distortion, not than unruly word my fingers actually typed! By the way, my SVS sounded much different when I bought it than it does now. It took several hours with a BFD to EQ it flat. And I mean FLAT. Not close with 1/6 or 1/12 octave measurements. I used a tone generator and burned a disc with all frequencies between 10hz and 125 hz in 1hz increments. Each was recorded for 10 seconds, which gives me enough time to record the results. I use a RS meter and use the correction values to get a reasonably close response curve. Then I adjust the BFD. I used all 12 of the bands, and starting with the lowest point of the response curve, lowered each peak until I figured I was ruler flat on paper. After rechecking with the meter, I am quite sure that I am within a db of flat from 18hz to 100hz. It took a long time, and was a fair amount of screwing around (116 different frequencies, and a whole lot of correction values for the Rat Shack meter), but it sounds fantastic. I agree that each sub will sound different depending on its output response curve. I like accuracy, so I play. I am quite sure that I even GAINED some headroom, because even though my deepest lows ended up with a boost (by cutting everything else and raising the overall gain) the balance is much better, and truthfully, really deep bass is not a full time deal. Most bass that occurs regularly is found above 40hz, which is where my biggest peaks were.

Nah, not yet.. I still don't like that speaker hanging out on the end deal.. Scary..
I'm on my over there right now, for lunch agian.. Going to ask for a look see at the inside of the TN line.. Don't know if that will happen, but never hurts to ask...
Will also ask about the new STF ? I saw a post here early today, somone mentioned it.. STF 1 and 2 ?
I do like the slimmer lines on the Hsu as opposed to the SVS, but have not seen an SVS in the flesh as yet.. Might not be that much of a diff ??

hey will, i was the one comparing women....hijacking the thread in other words. i wouldn't get so technical about subs, unless it was steak, cheese, and mushrooms.

They are very different. If Zen ever pops in again, maybe you could head down to SD to hear/see his.
