Congratulations on having your arrays up and running! You really work super fast!

I'd love to hear more about your impressions, especially if you experiment with different toe-in angles or different speaker placements/listening positions and so on... 🙂

Thank you guys - just got home from a weekend getaway and will start to attempt finetune the arrays and get REW up and running 🙂
The suggested music tips are appreciated, I saw a few familiar identities but most are not well known to me 🙂 Heard of, not familiar with 😉

The array have been playing all weekend and should about now have about 200hrs on them so I will consider break-in period for completed 😀

Another list of fun songs to check imaging etc:
Infected Mushroom - Avratz
Russian Circles - Harper Lewis
E-40 - Tell Me When To Go (feat. Keak Da Sneak) - Deep bass test 😉
Almost any song by John Barry such as The Ipcress File etc. - great atmosphere
Hans Zimmer - Angelica (Featuring Rodrigo Y Gabriela)
Emerson Lake & Palmer - Still...You Turn Me On - great mix of in phase / out of phase

Thanks again for the suggestions and also to mayuri for putting up a playlist 🙂
Have only had brief time to use the arrays and have used that time to listen to music, not analyze it 🙂 I am currently tiling a room in our basement that take most of my time at the moment, honey-do... 😉

However I have come to the conclusion that my drivers arent airtight against a smooth MDF-surface, I can feel them leaking out to the side during low frequency playback. Any suggestions for gasket material? I need to remove all drivers anyhow in order to paint the MDF 🙂

You can carefully remove the front gasket and glue it to the backside with rubber cement (which is removable easily). I use thin EVA foam sheets used for crafts - in the US you can buy from any art or craft store like Michaels'. I have also seen it at dollar stores. Many times they come in bright colors for decorating and not just black. It works really well and is very similar to the gasket that comes on the front of Vifa. Cutting 40 of those foam gaskets by hand can be a chore though. Plumbers' putty works too but leaves an oily residue.

I did try to remove the gasket of one speaker but didnt find it particulary easy to do properly, fail ratio with 40drivers would equal few 😉 I have a couple of ideas for suitable materials, will test tonite.

But yeah, hand cutting 40 pcs will be a chore but so was mounting 160 screws 😱

Indeed 🙂 I expected proper sealing to be required since the Vifa TC9 comes with gasket material on the outside 🙂 I have considered making a new front baffle allowing rear mount which also double the baffle thickness. Then I can also incorporate some sort of a wave guide... :magnify:

Don't do that!.....you'll wind up with all sorts of diffraction with 35mm deep hole. Rear mounting on a single ply baffle is fine.

If this is a sealed box you only need the airtight seal to ensure that the driver's excursion is well controlled at xmax. The leak is probably small and not going to influence cone excursion that much. Given that these are high Qts drivers I think it is probably ok to have slight leaks. If this was a TL or BLH then leaks are bass killers - but probably not critical here.

X - the cabs are sealed and since I need to remove the drivers to paint/finish the exterior I´ll address the seals also 🙂 I´ll find a good way to accomplish a proper seal 🙂

Just got back from a 2hr listening session, I like these... 😀
