The first two G1s are built and up for testing. Still need a bit of work, but we are getting there.
It was nice to finaly get started on building these smaler boxes for a change. Did some minor mods to the cabinet to suit a polemount on the side aswell to be able to put them on stands both ways. This just adds two vertical bracings instead of one in the middle.
This cabinet is built with 15mm Poppel, but still a quite heavy box even with the neo magnet on the 12" driver. Still managable for most people to carry around, would guess around 30kg.
Here is some pictures, but not too much of the actual building process...
Temperary bracings to make sure the box is square under assembly.
Drivers and horn installed. The plan is to make brackets that supports the horn to be turned 90* easily. This will make the box more versatile.
Sanded edges. Here you can see that the plywood is chipping off smal pieces when cut/grinded. This is a problem with using cheap plywood as poppel.
We put them to work this weekend at a smal private party.
Feedback from that first fieldtest was a bit harsh sound in the upper region when you turned the volume up and drowing the mid a bit. This could be the room, but also adds to our first impression when testing in the garage.
This could be the distortion levels from the BMS4550 at higher volumes when crossed over at 800hz, but we are going to explore this further. They sound quite nice at low/medium levels, but the distortion becomes really noticable when cranking the volume up. The Lavoce WAN124.01 sounds really good, dynamic and clean, even at really high volumes.
Had to tone down the 200hz area and also 3-4000hz, but gain 550hz and everything above 5000hz. This is just from listening to the box, so we will see if that is correct when we get some measurement data.
Next bloggpost about the G1 is going to be just about tuning, and installing phaseplugs to raise the crossoverpoint and hopefully reduce distortion.
