Huang Posted July 10, 2021 Share Posted July 10, 2021 Last weekend my Rel sub gave up the ghost I believe it's the amp, fusses are good. Well I had been thinking about a Vandersteen sub, cause they blend so well and Stratocaster's sounded so good. The Sub 3 is where I probably end up but I was offered a 2WQ with two M5-HPs for a great price. The filter battery was marked 2021 so I swapped them out. I have access to a full electronics lab so it was pretty painless. What I did notice was the battery was ready to go (see pictures). If you have filters with batteries CHECK THEM! It would be bad to have battery ooze on Richard's fine boards. My other question is how does the HP filter work. I know you put it after the preamp, then connect to the amp. If the output of the pre is HP filtered how does the low frequency information get to the sub? Link to comment Share on other sites More sharing options...
Richard Vandersteen Posted July 23, 2021 Share Posted July 23, 2021 Huang, on this site is a tribute to Dich Hardesty which you should download the issue about sub woofers. Dick did a better job of explaining how our 2Wq/SUB THREE works than I ever could as he was a writer. Dick was a very good musician (piano), engineer, writer and had Havens and Hardesty audio store. He had a gift to write complex subjects and make them simple. Read his sub-woofer issue and you will know more about subs than you wanted to.

Steve Edwards Posted July 23, 2021 Share Posted July 23, 2021 I bought my first pair of Vandersteens (2C's) around 1986 from Richard at Havens and Hardesty. He provided me with my first introduction into high end audio equipment, and, as RV states, he could explain complicated audio / electronic functions in understandable terms.

Huang Posted July 23, 2021 Author Share Posted July 23, 2021 Thanks, I'm loving the sub, I was just curious how it works. Thanks for you contributions to the forum too Richard. Link to comment Share on other sites More sharing options...
GdnrBob Posted July 23, 2021 Share Posted July 23, 2021 I am a bit confused... Did you get one 2wq sub with two crossovers? Bob Link to comment Share on other sites More sharing options...
Huang Posted July 24, 2021 Author Share Posted July 24, 2021 Yes, currently I have 1, 2WQ and two M5-HPs. It is so seamless, I may add another 2WQ, or jump to a Sub Three. I wonder how a Sub Three would play with a 2WQ. Link to comment Share on other sites More sharing options...
ctsooner Posted July 25, 2021 Share Posted July 25, 2021 Richard would be the one to answer this properly, but I would think that the sub 3 sounds 'better' than the older model and therefore wouldn't match teh sound of the 2WQ. I'll be interested to hear the answer. Link to comment Share on other sites More sharing options...
Richard Vandersteen Posted July 25, 2021 Share Posted July 25, 2021 Huang, you would be better off finding a 2Wq in good condition used to match your existing one. The SUB THREE is a much better sub as it has more power, improved cast basket drivers, a more powerful power factor corrected regulated switching power supply and room EQ (11 bands). I think it would be better to have them matched or sell the 2Wq and get a SUB THREE and add another later when funds are available and use the room EQ.

ctsooner Posted July 25, 2021 Share Posted July 25, 2021 Everyone I've spoken to who has done the upgrade and gotten the Sub 3 has felt it was well worth it. Link to comment Share on other sites More sharing options...
GdnrBob Posted July 25, 2021 Share Posted July 25, 2021 Yup, moving to the Sub 3 definitely improved my system. Even at list price, the cost isn't that bad for what you can achieve. Room correction will make your speakers perform closer to the next model up. @Huang, I still don't understand why you have 2 M5-HP's? I hate to be nosy, but I never heard of anyone with a single sub having 2 crossovers.-Unless someone was only selling a pair... In any case, you can use them with either a second 2WQ or a pair of Sub 3's. B 1 Link to comment Share on other sites More sharing options...

Huang Posted July 26, 2021 Author Share Posted July 26, 2021 Bob, correct I have one M5-Hp on each amplifier channel input (left and right). There’s a left and right input on the 2WQ so, am I doing something wrong? Link to comment Share on other sites More sharing options...

Yes, you could use only one filter and connect it to only one channel, but that would assume the bass is the same in both the left and right channels.

stratocaster Posted July 26, 2021 Share Posted July 26, 2021 @GdnrBob how have you connected your Sub3? You need a pair of crossovers (fixed or MPs) irrespective of whether you are using a single or dual sub. I have seen some amp manufacturers incorporate a crossover internally for the subs (especially Ayre) but I would still expect that both channels would get that customization.

stratocaster Posted July 26, 2021 Share Posted July 26, 2021 @nrentertheoretically you can connect just one filter but in reality it’s counter intuitive since from a stereo perspective there’s hardly any processor or preamp on the market that can cleverly collate the bass frequencies and route it to a single channel and present the music the way it’s supposed to be. At that point you may as well use the 2wq as a coffee table or trade it in for a V2w and let the processor send everything to the LFE channel… Link to comment Share on other sites More sharing options...
ctsooner Posted July 26, 2021 Share Posted July 26, 2021 I sold my Ayre AX5/20 that had their internal crossover (they used their best caps etc..) and it sounded great. Link to comment Share on other sites More sharing options...
GdnrBob Posted July 26, 2021 Share Posted July 26, 2021 @Huang, @stratocaster, I was unaware you/he had monoblocks. So, yes, it makes sense. Bob Link to comment Share on other sites More sharing options...
