HD15/Reflex Bass Cab

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I've been thinking of building something like this for a while. I built a pair of HD15's a few years ago and was always really happy with the sound when they were coupled with reflex PD186 boxes, time aligned. Always wanted to build a single box version of that sound. I'm intending to build four (2 either side), with some 3 way - Mid/High cabs on top. I will probably have to make the boxes an extra 100mm deeper to increase the rear chamber to 300 litres for an 18inch driver (only thought of that after I'd plotted to pdf). Anyway, would welcome some thoughts.

	I'll be honest, I can't see any advantage in that over using separate reflex and kick cabs, dare I say it, having separate cabs would even make the system more versatile. I do like the idea of using aluminium for the curve and brace, my old HD's would suffer quite badly with power compression when driven quite hard so having the curved part made of aluminium would help a lot in that respect I suspect.

	Why?. That box will be a 2 man lift, you'd be better off building 4 single 18s and 4 HD15s.
	If it's got wheels or tits it's gonna cost a fortune

	Wouldn't it be overall easier to manage (load, unload, stack, stock, be modular) to have 2 separated boxes? I don't really see the benefits of putting all in one big box, only downsides

	The idea is a bit unusual. Would call it full range bass cab ^^. I had a similar idea but with a BMS 2236 horn and a 12" but couldn't get it down to a in my opinion reasonable size.

	agree that there's no good reason to build them like this. about half of the places i go involve stairs..

	Thanks for the replies, at least nobody said they'd sound shit! I'm quite fortunate that we never have to worry about stairs. Most of the parties we do are in remote areas or beaches.There are always at least 4 of us so lifting a few boxes off of 4x4s in no real drama. I absolutely agree lifting big boxes up flights of stairs is a tuff gig. I'm going to give these a go and will post some photos once I start machining them.

	If the lifting issue is no problem for you then build them, looking forward to seeing the end result

	Looks good! As you say if you don't have stairs and have all hands on deck... you should be fine. Nice to see something a little different! I would be against putting them into one box too but if it suits your needs... why the hell not! Edited by mini-mad - 09 June 2018 at 8:56am

	Looks a lot better than I'd expect two bins stuck together would look like. Stick a full face grille/foam cover on 'em and leave people guessing about what beast could be laying within!
