That is some nice wood work over there. Bet it sounds good! Maybe you can make the HF cabinet have the same width as the other boxes? Would look lovely :) 
We need more SPL!

 So, since moving away from HD215's a few years ago and going to 18" reflex cabs I've enjoyed having that bottom octave that was completely missing with the HD's but I've missed that punchy 'in your face' sound that the HD's had so I decided to knock up some Turbosound TSE 118 style cabs to go on top of the reflex cabs. 

 Apologies in advance for the quality of some of the photos and lack of detailed photos, I just took the odd photo as I was building. 

 First job, lots of cutting with my diy saw guide; 

 
All panels cut; 



Carcasses assembled and battens added for the access panel;



 Then I fitted the baffles and guides for the curved piece;





 After that I made some cutouts for the speakons; 





 To form the curved piece I fitted a load of battens around the guide/former pieces, then bent a sheet of 6mm ply over the top; 







 Then I fitted the top panels, braces and sound reflector piece; 



 Cutting out the braces; 



 
 Fitting inserts for the access panels and access panel test fitting; 





 I also knocked up some flared mids whilst I was at it Smile



 Front battens added and edges rounded over; 



I did some testing after that, oh, and knocked up some horn boxes (I've stuck a new dust cap on that mid too!)



Filling and sanding (I HATE filling and sanding!); 



 First coat of paint on; 



 And the finished cabs; 







 With the mid and top cabs; 





 The comps are BMS 4550's and by christ they're good! I've never heard a 1" comp capable of going so loud whilst sounding so crisp and clear. 



 I used the cabs in anger for the first time last night and was very happy with the results, I've got the punch back! Big smile
