So.... they're finished! Like a dumbass I didn't get any pictures in decent lighting, so here's a very unflattering teaser photo:

I haven't really had much of a chance to listen to them as TV is king in the evenings but initial impressions are OK. I need to work on their positioning a lot but this was just a test to make sure everything works. There is a hum out of the amp which is irritating and I can't see a reason for it and I hope it's not the power supply.

You don't have them off the floor much -- and with carpet you might find a hard base to help the bass.

You do need to get some hours on the drivers...

Commited,

Congrats on completing your first build! I did mine last month - a BiB with Fostex Fe166en.

The BIBs are pretty amazing. As Dave has suggested, better start getting hours on the drivers. As a FR newbie, I am also learning that the drivers tend to change a lot as you start piling up hours of play.

Hi Dave, I'll definitely be raising them off the floor thanks, I just wanted to check that they actually worked!!

Zia, I'm not really getting a chance to play with the drivers as the amp has a horrible hiss that I'm trying to get rid of!

So I thought I'd give this a little update as I've now been listening to them for a few days. It's pretty difficult to get some dedicated listening time as we're currently living in someone elses house which is also compromising placement. To make things even more difficult, my TK2050 amp turns out to be faulty so they're currently being powered by an Aiwa karaoke system which is pretty horrific. Couple this with an ipod as source and I should be tearing my hair out.... I'm not. You can tell, even with this awful source & amp, that these speakers are something special. I can't wait to hear the speakers in corners of a well shaped living room with the TK2050 amp and my Monica 2 DAC. Shouldn't be too long away! Thanks Dave for the heads up on the drivers and help with the speakers so far!

I have now ordered some 30mm long spikes to go under the speakers and I'll be using some of my leftover plywood to make some bases which I'll spray black.

I'm going to cut the karlson slot in the speaker soon. I'm going to start off with 1 on each side approx 50mm x 200mm - any opinions on this size?

Te scheme i plan on using if i get as far as building a set, is to use a grid of holes (in one of the Karlson documents), as illustrated in the attachment. The staggered grid looks better to me.

Slot can be easily grown and leave the panel stronger.

That looks like a serious amount of holes to drill, or am I being stupid?!

I was going to draw the outline of a small size slow and cut out with a jigsaw! Then I was just going to cut strips off until I was happy.

Thanks Dave - I'll be able to give a proper update when I have some decent amplification.
