Best musician in the world?
Talk about resurrecting an old thread!  23 years! That must be a record! While Galbraith is/was excellent, I would currently vote for Jordi Savall: performing and conducting music from all over the world composed over a period of thousands of yea...

@lewm  Yes, that makes sense.  I'll see how things work out.  Presently, with just the SL speakers, and playing the 16 Hz note on vinyl, the walls shake;  oddly, playing the same piece on digital doesn't cause much to shake, but just the normal v...

@lewm  The standard amplifier that he pairs with his subwoofers goes down to 18 Hz.  We'll see what he's able to find.  (By the way, if you haven't heard that organ piece, you should give it a listen.  My friends who don't even like classical mus...

@rauliruegas  Thanks for your suggestions.  I'm going to see what Duke at Audiokinesis comes up with.  He sounds like he really knows what he's talking about, and is interested in helping me get the best out of my Sound Lab ESL's.  He's also a So...

@mijostyn  I spoke with Duke LeJeune at Audiokinesis, and he agreed with you that the "Swarm" would not suffice in my room, due to its size.  He mentioned that he could make some custom subwoofers with either 12" drivers or possibly with s 10" dr...

I've read some comments on a subwoofer thread about how the user preferred Class A/AB amplifier for the subwoofers, as the class D truncated notes too quickly, and the like.  Consquently, currently, I'm leaning towrards favoring passive subwoofers...

Hmmm. . .I’m back to the consideration stage: apparently, the most neutral approach to add a HPF in my current system is via a high-grade capacitor. However, these capacitors only give a 6 db / octave adjustment, which means starting at 80 Hz (so ...

@holmz My pre-amplifier has two outputs: RCA and XLR, so I can run the RCA to the amplifier and the XLR to the subwoofer, or vice-versa, as the amplifier has both RCA and XLR inputs. I was leaning towards a lower crossover for the HPF, somthing ...

Not to dissuade anyone, but the where are the transducers, and how many are there? It looks like it’s only got 80 W power to a 48 kHz transducer(s). The cheap VEVOR has 3 x 40 kHz transducers at 180 W (3 x 60W) at the base. The Degritter has 2 x 1...

@mijostyn Understanding that digital LPF is better for sub woofers, can a high grade analog capacitor (e.g. silver Duelund CAST) be used for the HPF to the ESL with good results?  What’s the main disadvantage to using an analog HPF via an in lin...

@lewm because of the quality components of the pre- and amp, I am leaning towards an capacitor HPF, as opposed to running it through the sub, which just has a standard 6db per octave HPF, which would just be a standard, probably low-grade capaci...

Correction: I finally found a diagram of the back of the Velodyne subwoofers under quick start guide on their website. . But it’s a very poor diagram, and doesn’t explain anything about the HPF, LPF, etc. It looks like their target is the home the...

@holmz  I was just reading multiple reviews about various HPF and they all say that there is a noticeable affect on SQ.  But I suppose it's worth a trial.  The current problem is finding the best ones to initiate this trial with:. Vandersteen, Ma...

@rauliruegas @lewm Which Velodyne subwoofers would you recommend for best match and highest quality? What about Martin Logan subwoofers, or other brands?  (Velodyne has no photos of the back of their subwoofers and no diagram of connections on t... 
Phono Stage upgrade to complement Dohmann Helix One Mk 2
@rauliruegas  Yes, you would be correct that I have no experience with subwoofers.  Does the Velodyne insert into the system between the pre amplifier and amplifier, with both a LPF for it's own amplifier and an internal HPF that then is sent to ...
