The Legacy Wavelet DAC/Preamplifier & JL Audio Dominion Subwoofers | DSP Dilemma & System Review

[@mattkozink7488]

I smiled when I heard Tom's comments toward the end of the video regarding time spent obsessing with the "tweak-o-rama" process vs simplicity of set up with the Wavelet DSP system. In my mind it begins and ends with the music and how one most enjoys it. Thanks Tom, point well taken, although I do hope you explore how one can tweak the Wavelet's number crunching with alternative locations of the subs.

Great video. Great mag. Love legacy speakers.

Glad to see magnepan come out with bipolar subs, that said eq and time Domain makes a huge difference below 100 hz ,Just ask anyone who’s heard a pair of Vandersteen model fives and up the difference between flat EQ and properly adjusted eq in the room. Note: 11 band eq below 120 hz.

You should try different toe-ins with your speakers, with the DSP processing enabled. You observed an increase in width with your initial setup. I have found that the Wavelet increases sound stage depth. Once the toe-in has been done, redo the Wavelet calibration.

[@thomasmartin2219]

Interesting. Magnepan is pretty insistent on a specific toe in to get the tweeter and woofer in phase. But this could be useful for symmetrical speakers. And experimenting with this is easy!

@@thomasmartin2219 To test out toe-in, I used the Letter track on Yosi Horikawa's Wandering album. It has the sound of a pencil scribbling on paper, moving across the sound stage (near the beginning and end of the track) from left to right. I listen for a constant speed movement of the pencil without dropout in the center. I start with the speakers pointing directly forward, where there may be drop out, or where the sound stays on the side of the sound stage before jumping across a gap in the middle. I toe-in and try again. As soon as the movement is constant without dropout at the center, I stop. Of course, one could use any track where there is constant movement of a note across the sound stage from left to right.

You can get a lot of the Wavelet functionality with the NAD C658 with Dirac. Adjustable high/low xover point but no time domain. At nearly three times the price I assume the Legacy will perform at a higher level but the NAD is more in line with the price of the Maggies.

Please review some actual Legacy loudspeakers.

Nice review👍

Hi Tom, great video. Regarding the time delay between Mains and Subs, I didn't see how it is done by the Wavelet. Is it automatically defined? In your case how many milliseconds was needed (I suppose the delay was needed for the Magnepans). Thanks again

[@SuperMcgenius]

Good to see hifi using pro audio Features like dbx that has had it for a long time. That the crossover points are not adjustable, is real letdown. Time Domain/ phase may be challenging concept for some listeners, maybe a small explanation would be helpful to some viewers.

[@esylsten]

You never mentioned that DAC performance, you said you would get to it but I never heard it. Is it a typical $1500 DAC, better, worse? Would one sacrifice performance if one is used to a better say $3000 DAC?

I have been reading TAS since late 80s and really like the magazine. Lately I have been seeing the reviewers showing up on KZbin for reviews and new product introductions. This is great. Looks like TAS is in transition to online reviews. However, may I suggest you use high quality microphone to capture the sound so we all can hear. I understand the sound captured and listened on KZbin doesn't truly represent the sound heard at the review site. I rather read your magazine than watch you talk for 30 minutes without any music and without showing how to set up the equipment (using the microphone and hooking up Legacy Wavelet in this case). For lack of better word, this video is boring.

OK- quarter wavelength. Is that of the crossover frequency? Which was? (120 Hz?). Or 1/4 of the room width, and whatever frequency that works out to? Thanks!

[@thomasmartin2219]

It is 1/4 of the wavelength that corresponds to the dimension of the wall where you are placing them. So, 1/4 of the distance between left and right walls at the wall/floor intersection. In Toole’s testing for Harman, he was testing 4 woofer setups IIRC. I don’t believe this 1/4 wavelength on the front wall and back wall was his best result (which I think was at the centers of each of the 4 walls), but the 1/4 wavelength point was better than many other options. In my room, the centers of the walls won’t work because of a doorway.

[@thomasmartin2219]

The Wavelet here has low pass options of 110 hz and 70hz. I was using the 110hz option at Bill Duddleston’s recommendation.

Lots of elephants in that room... ARC Ref DAC? The Jeff Rowland stereo amp...? Observations only...
