Just curious what's the rationale for crossing the GZ at anything above 50Hz when they have an internal crossover (high filter pass) that is hard wired at 5000Hz and they have a range down to 50Hz?

 

The crossover cap is only for the tweeter. The woofer still needs a HPF. While the specs may say down to 50Hz, they don't play it with power. If you can get 90Hz to play well on that speaker with rated power, you've accomplished a lot.

 

Everybody has different ears, and speakers often sound different to others. If your GZ coax are sounding ear piercing, I have to question the validity of your x-over frequency settings.
The Hertz Neo coax I have in the tour pack, are much brighter than the GZ coax, to the point that the highs in the Hertz Neo can overwhelm the highs on the GZ coax with no problem.
Guys call the DB Moto G2's ear piercing as well, but I find there is a sweet spot on some speakers, where x-overs, when set properly, allow the mid-range to shine, and balance out those highs.
Without a DSP, a CC1, or RTA to check your settings, you really have no way to know what frequency you are actually setting your variable dial at on your amp. Sure you can estimate your settings on the dial, but your accuracy is not guaranteed. That brings it down to setting the x-over by ear, which isn't always a bad thing, as long as you take the time to tweak it and find that sweet spot.
Personally, I find the highs to be rather mellow on the GZ coax. Probably the most mellow coax I've tried to date.
That being said, without a DSP, a guy leaves a lot on the table, for any speaker to reach its full potential.

 

Like to know what you used for those speakers please. I'm attempting to this on my Softail.

 

It looks like he has GZ 6.5 coaxial in those pods from what i can see in the pic

 

Search & go through my past few threads...there is a post on what you need to make the pods happen.

 

My 4 6.5 Ground Zero Coaxials with a SD 800.4 and a Arc Audio Psm Dsp. It rocks with the right tune.

 

Wow...only 140w to each...downloaded the video but I can't play it 🤷🏻

 

Yup...I'm only sending 150w to each my GZ's with my Arc Moto 600.4. I know most are sending 200+ but for my needs, I'm pretty pleased.

 

Loved them in my fairing, but hated the fairing on my Heritage, working on installing them on the engine guards, just need the BT adapter and longer speaker wire.
