A9X Posted September 12, 2018 Share Posted September 12, 2018 They are shaping up very nicely. 1 Link to comment Share on other sites More sharing options...
BioBrian Posted September 12, 2018 Share Posted September 12, 2018 Nice matching of the grain. All looking superb. How are you getting the corner radii to match - I don't expect there's a router bit of this size. Link to comment Share on other sites More sharing options...
Guest Peter the Greek Posted September 12, 2018 Share Posted September 12, 2018 Love the work, awesome stuff. Agree the grain is very nice. @BioBrian CMT make a 38mm round over bit. Looks about right to me Link to comment Share on other sites More sharing options...

How are you getting the corner radii to match - I don't expect there's a router bit of this size. I'm using Freud 1 1/2 inch bit (30-140) http://www.freudtools.com/products/product/34-140 There are a couple issues when using this size router bit 1) not many new routers at least those which are available in local stores will fit this size router bit so I had to make a template and still, not a perfect fit as the router is only sitting halfway in the housing/shank and also no too much space to tighten it up properly !! 2) due to all the above and more, very dangerous to use but as you can see I did make it work ( several passes like 5-6) 1 Link to comment Share on other sites More sharing options...
BioBrian Posted September 12, 2018 Share Posted September 12, 2018 Wow. They should sell suits of armour with those. And with no(?) depth adjustment, it must be pretty fraught doing the first 5 cuts? Link to comment Share on other sites More sharing options...
jkn Posted September 13, 2018 Author Share Posted September 13, 2018 (edited) So finally finish the project I'm actually happy as I tend to move to another before ending the previous one - all is left is measuring and setting it up but so far it is looking good posting some pictures Edited September 13, 2018 by jkn 7 Link to comment Share on other sites More sharing options...

niss_man Posted September 13, 2018 Share Posted September 13, 2018 Looks great Jiri. I am glad you got to finishing these very worthy speakers. I see you've done some large changes to your rack and gear as well. Link to comment Share on other sites More sharing options...

Yes, I kind of downside the rack as I did not need it all the gear>I also went for pro amps driving the bass (found some quiet one's sort to speak )I do have 7500Watts per side (speaker) so I don't think I'll be running of power anytime soon. I upgrade to Mutec MC3 USB Which is a really good little unit for PC audio. Next step is to do all sound treatment I have in mind J Link to comment Share on other sites More sharing options...

I'm using 4 off SAE TX 2400 (bridge mode) they are cheap, reliable and good sounding amp also the most important they are very quiet in operation mode SAE PCM series are better amps as to finish and sound quality and power but they do get noisy in a home environment Edited September 14, 2018 by jkn Link to comment Share on other sites More sharing options...
Guest Peter the Greek Posted September 13, 2018 Share Posted September 13, 2018 Quick question. Did you pour the concrete wet or just put in dry? Link to comment Share on other sites More sharing options...
CamSemp Posted September 13, 2018 Share Posted September 13, 2018 They look so good!! What sort of finish did you use? Are the separate boxes attached to each other somehow? Or just sitting there? I suppose with those weights they're probably not going anywhere! Link to comment Share on other sites More sharing options...

Not sure what do you mean by what sort of finish did you use. These panels where already veneer so on the end I just gave it of wash. The boxes are sitting on anti-slip packers which I have found at bunnings 5mmx40mm round Link to comment Share on other sites More sharing options...
jkn Posted September 14, 2018 Author Share Posted September 14, 2018 I have done some setting this morning posting some pictures. They do sound really good but that comment could be biased,,,,,,, The best scenario would be if someone else auditions and comments on the sound Link to comment Share on other sites More sharing options...

It looks pretty good to me SORT OFF that is If I use different software like raw or holm the FR would be pretty flat. I can apply more EQ to the existing measurements but sometimes it works/sound better without too much eq. Anyway, I think that within +6+6 DB FR is kind of good reference. I think the tweeter is just fine don't need any eq there is suck out at crossover point at 1600 which I don't usually fix with eq I just leave it as it is. A bit Massy is the bass crossover point but..... Subs Left is just fine the Right has nasty dips which I can not fix > unfortunately, DEQx has not separate EQ (left Right) option Edited September 14, 2018 by jkn Link to comment Share on other sites More sharing options...
Mushroom01 Posted September 14, 2018 Share Posted September 14, 2018 (edited) Looking very good indeed... I really like the look of natural grain of good quality ply. Did you need all the weight that comes with the concrete fill? I only ask because you can add polystyrene beads (bean bag beans) to the wet mix to save on a lot of weight. Cheers!
