Stompbox Posted December 20, 2014 Share Posted December 20, 2014 (edited) I have a 2 x 10" Ashdown cabinet of 8 ohms impedance, and a Mag 400 amp - which will deliver 400 watts RMS into 4 ohms. I decided to build an "Ashdownalike" based on the dimensions of my existing cabinet, the new cabinet also to have an impedance of 8 ohms. The idea is, for larger gigs I can take both cabinets & stack them on each other and thus be able to drive the full 400 watts into the pair. I also have an Ashdown 180 "Blue" head that is just the right size to put on either of these cabinets if I stand the cabinet on its narrow side. All in all this should give me quite a range of different setups. I saw some 10" Celestion bass drivers with a 16 ohm impedance for sale very reasonably priced on Thomann's site & so I ordered two of them. This all goes back for quite a good few months now, before I moved to my present house, and I got the other parts, the covering material and the wood cut and determined to bring it all with me as a "flat pack" kit, ready to start on it when I was settled in, so:- Here are the bits [attachment=179020:Bass cab (3).jpg] I used glued & screwed construction - nothing clever or a shining example of woodwork, but, hopefully a sound, simple cabinet. Here it's starting to go together. [attachment=179021:Bass cab (10).jpg] This shows the main cabinet body, and the speaker baffle with the edging struts to support the metal grille fitted, and the "shelf" that forms the upper side of the front port slot which has now been attached to the front baffle. I painted the front baffle with black Tuff Cabinet paint, also the areas inside the port that will be visible so that the port would not show up in its wood colour. Now these two main sections are joined together [attachment=179023:Bass cab (15).jpg] Here's the metal mesh grille in grey primer ready to have satin black spray paint applied [attachment=179024:Bass cab (17).JPG] Now to cover it - oh joy, a tin of spray glue from Screwfix and a tin of Evostick adhesive...... [attachment=179025:Bass cab (18).JPG] More spraying, cutting, glueing (oh yes, and cussing). [attachment=179026:Bass cab (21).JPG] On go the corners & handles ( I went for spring loaded ones rather than the inset types with big cut outs in the cabinet sides as it's simpler). [attachment=179027:Bass cab (26).JPG] Now pretty well complete - I took it to a rehearsal and did an A/B test with the old cabinet - this is definitely a touch louder and has a bit more OOOMF to it - if I can describe it in such a technical manner. [attachment=179028:Bass cab (31).JPG] I'll put a couple of final pics on to show it with the other cabinet & amps in the next day or so. Hope this is of interest.

Beer of the Bass Posted December 21, 2014 Share Posted December 21, 2014 You've done a neat job of that. What sort of ply did you use? Quote Link to comment Share on other sites More sharing options...
Truckstop Posted December 21, 2014 Share Posted December 21, 2014 Very cool! Good work pal, you must be well happy with the extra oomph? Truckstop Quote Link to comment Share on other sites More sharing options...
Stompbox Posted December 21, 2014 Author Share Posted December 21, 2014 Well thanks for the comments there guys - I used 18mm ply that was stamped "Imperial", 1.5" number 8 screws and Evostick waterproof PVA glue. The speakers are 16 ohms impedance Celestion BL10 100s . The cabinet is lighter than the original Ashdown as I think that on the original cabinet only the front baffle is ply, the rest is particle board, but the two Celestion drivers are heavier than the ones in the Ashdown, so it's about the same weight overall. It's not one for the purists, but yes, I'm pleased with the result as it's a decent amount of "bang for your buck", and it is exactly what I need at the moment. I bought the cabinet paint, handles, corners, covering fabric & feet from Blue Aran. Pics of the completed unit - firstly standing vertically with the 180watt "Blue" head on it [attachment=179071:Bass cab (33).JPG] Now horizontally with the 400W head [attachment=179072:Bass cab (34).JPG] Finally as a "stack" to get the full rated power with 4 ohms overall loading [attachment=179073:Bas cab (35).JPG] Quote Link to comment Share on other sites More sharing options...
Merton Posted December 22, 2014 Share Posted December 22, 2014 Nice work I see you have Geddy Lee's signature "cab" in the background too Quote Link to comment Share on other sites More sharing options...
