I had a question, how do I know how good a sub is?

I dont have much experience with many subs, in fact I have only used 3 in my own set-up.

I have heard other ones, but cant get the same comparison due to different rooms and speakers.

Frequency response and db output at its lowest rated frequency response is what you need to look for. A sub that only goes down to 30Hz is just starting to get into the frequencies that really hit you during movies.

First we need to define "What a good sub is" for you, What do you expect from the sub???....

For example, I thought that my two subs (Velodyne VRP 1000 and Infinity TSS 750 150RMS and FR 35Hz-150Hz) were good to me ...until I went DIY and build a Sonosub (850RMS 15Hz-150Hz)with the help of some members from HTS :T; I still think they're good to start the HT experience, but not for me anymore...

I agree with Tony, most subs that has a FR from 20Hz and at least 300RMS can be considered good subs, specially if is a know brand name :yes:

Alright, alright.

Well, when i got an email from one of the tech guys from SVS, he was saying that the numbers arent all thats important when picking a sub.

Here's his response to my email a couple months ago;
Just a preemptive comment regarding your below questions: It is a difficult to estimate a subwoofer’s performance by studying variables like amp power and woofer size/stroke in isolation. We prefer to simply show you what the subwoofer is capable of as a system, with respect to frequency response, maximum clean output, compression and distortion – because those are the things which really matter to the end user. The performance is a complex interaction of woofer, amp, cabinet volume, port size, and system tuning frequency. Few subwoofers have this kind of performance (as measured outdoors at 2 meters) at any price, much less the very affordable MSRP of the Ultra. The Ultra has more clean output at 20 Hz than the $10,000 Genelec HTS-6 for example.

That's true ..."The numbers are the starting point to make a decision to buy the subwoofer" :yes:

What he said in the email about woofer size, port size, frequency response, maximum clean output, compression and distortion etc. is also true, but the question is: Do all companies publish this information??? ...Will the subwoofer perform the same in your room??? ...Will you be happy with the performance??? ...there's a lot of variables to say that everybody will be happy with the same sub. :yes:

Like I said before, give the Velodyne VRP1000 to somebody who has no sub or has been using an HTIB and I bet you they'll be happy ...but, give the same sub to somebody who uses a bigger sub (either brand name or DIY) and I'm sure they will not like the performance, the subs is like anything else; when you move up the ladder you don't want to go back down :bigsmile:.
