Here are pics of my holiday project. I made a folded horn a couple months ago but it can't go as low as I want. I use a minidsp to send 15-40hz to the sealed sub and 40-120hz to the horn. A crown xls1000 drives both.
The box volume before bracing was 4.3ft^3 so it's about 4ft^3. I used about 4lbs of stuffing too. The pic shows the room response after some tweaking. The horn definitely had some peaks and valleys when I started.
I think it sounds really good. I had a radio station playing and I was surprised by the deep notes I never knew were in some of the songs :T I need a good new action movie to really test it out. I sat through The Fault in Our Stars with my wife :rolleyesno: , which wasn't a very good test.
Those are some nice results. I assume you are happy with the HF in the 4^3 sealed box? I ask because I am about to start a project with mine but don't want to nor will have the time to build my own box. I was looking at flat packs on PE and noticed they have a 3cf pack designed for that driver, but I'm afraid it will start to roll off before my liking. So I was thinking about going with their 4cf pack and cutting my own baffle.
I've had this sub for a couple of years now and just threw together a particle board box 'temporarily' to get an idea of what size box I wanted to go with in the future. I also am using an amp that I got over 15 years ago and have no idea what it's output is, but I know it's not much. With those two things combined, it sounds like to be perfectly honest lol. Between air leaks and the amp clipping I get the oil can effect without really driving it hard.
I've got a little bit of free time during the next month or so, so I'm trying to decide what I want to do with this driver to get the most out of it, without building a huge ported box. I'll probably purchase an inuke3000 to pair it with in case I decide to add another in the future.
I wanted a larger box for more bottom end and a 4cf box fit exactly were a small table used to be, a plus for the WAF. The sub gets 350w from the xls1000 and it plays clean right up until amp clipping. It can reproduce those grin inducing lowest notes :laugh2: My wife heard the REW sweeps from the side yard, so I think I'm good :smile:
