Mattias Andersson Posted March 17, 2020 Report Share Posted March 17, 2020 I have now built my firs Othorn prototype and noticed that the front grill wont fill out the mouth perfectly. Would it make a difference if I make the total width of the following boxes smaller by less then 10 mm or 3/8". What will happen to the FR, compression, the -3dB point, delay time, cone excursions and output if I made this chance? Yeah, I badly need those grills 😎 Best regards /Mattias Andersson Quote Link to comment Share on other sites More sharing options...
Mattias Andersson Posted March 18, 2020 Author Report Share Posted March 18, 2020 In between the amp and each Othorn a 5 meter of 4x6mm3 cables are going to be used. The big size cables keeps up the damping factor of the amp. And I like to build my own cables. Quote Link to comment Share on other sites More sharing options...
Mattias Andersson Posted March 18, 2020 Author Report Share Posted March 18, 2020 It's nice to have handy people around, helping me out to CNC "some" parts. Quote Link to comment Share on other sites More sharing options...
Mattias Andersson Posted March 18, 2020 Author Report Share Posted March 18, 2020 It's nice to have handy people around, helping me build some baffles in 3 mm of steel. Nuts should also be welded to hold up the B&C 21sw152-4 to the playwood baffle who sits in between the driver and the steel baffle. Quote Link to comment Share on other sites More sharing options...
Ricci Posted March 18, 2020 Report Share Posted March 18, 2020 Making the cabs smaller will reduce the efficiency and sensitivity a little. Should not affect the FR shape or extension much. It's only 10mm. Make sure you check that the driver will still fit after subtracting 10mm though. A 21" driver frame is already very tight in this box width. Have you thought about adding a bit of extra wood to hold the grilles instead of modifying the cab width? I'm interested in seeing what you have going on with the steel baffles too. Good luck! I will see if I can get a hold of Kyle about your picture bandwidth questions. Quote Link to comment Share on other sites More sharing options...
Mattias Andersson Posted March 18, 2020 Author Report Share Posted March 18, 2020 Hi Ricci, thanks for your input. My first idea was to put some extra wood for fitting the grill. The ply is still untouched so changes can still be made in the plan (I'm the guy who like everything in perfect fit) Considering the size of the 21" and the steel baffles are already cut out and welded so I'll go for some extra wood for the grills to have a nice fit. I gladly like to post more pics but can't, there is not enough space to share files 🤔 Thanks for trying to solve this out. Quote Link to comment Share on other sites More sharing options...
