Thanks!

Fun speakers to listen for music.

Avoosl came over today to help with The Megaliths moving to a new location in the listening room.

The prototype MS-5 Music Server is up and running with the dspMusikLCD 2x16 system.

Next step is to install the modified ribbon tweeters and wire them up. Then to get it all hooked up and running and try a new crossover idea.

The 8 updated GT Audio Works ribbons are installed and running in The Megaliths. Making music at this time.

Now for some new measurements to check the dspMusikLCD 2x16 digital crossover with the change to the ribbons. Tweaking the new positions as well.

That's gotta sound ridiculously good.

Rich, Let me and Jim G know when it's time to take a road trip down to hear them!

Can you say way has changed in terms of materials or sound of the new tweeters? Curious if you've compared to the neo3.

Tyson,
Just had a friend over that had not heard them in awhile. Played a live grand piano recording and it has the same large scale sound of the Steinway D. Effortless is a good description.

Having a digital crossover of this quality with this setup just does things very well. Full control over everything right from the computer playing music.

I think it will continue to improve as more measurements and adjustments are made as the new ribbons break-in.

Kemper,

Will be available after AXPONA if you both have time in April. Let me know dates and can arrange listening time.

The new ribbons are Greg's latest design material. The internal connection scheme has also been updated.

I have the BG Neo3-PDR's in The Monoliths setup in the other listening room. Need more time with the new ribbons to see what happens. Best I can say now is I like them both a lot.

Measurements on The Megaliths is done and the dspMusikLCD 2x16 digital crossover is updated. Ran MathAudio RoomEQ on the new HAL MS-5 Music Server and created a new room EQ that sound very good in this setup.

Listening sessions are available by appointment for anyone wanting to hear either The Megaliths or The Monoliths systems. Please PM me for setting up a time.

Just letting folks know The Megaliths are fully operational since some have asked about a listening session.

PM me for scheduling a demo.

Doing some comparison testing with a pair of HX300-12OB servo amps compared to the HX800-XLR3 servo amps on the 6x12's.

Having the ability to set the Fc on the servo amp to the crossover frequency above 120Hz will give some extra adjustment range that has proven to work well with The Monoliths speakers.

@HAL,

What are your XO points/slopes between the NEO10's and ribbon tweeters ???

TIA

Very insane, but also very cool project. Keep going!

HAL · « **Reply #297 on:** 17 Aug 2019, 07:53 pm »

Thanks!

Just waiting on the next generation of DSP crossover to try out with them. That should be fun!
