I'm starting to feel like once a quarter i'll get a hairbrained scheme and just want to do it regardless of what people may think....i'm fairly certain most of the speaker designs i've done have been a little wack in some form or another...Todays entry is really no different.
considering my speaker builds started by retro fitting a set of tower MTM speakers into a custom built TV cabinet and trying different woodworking techniques and progressing to kerfing and router work for everything, i accidentially stumbled on the expensive boenicke W5's. My desktop build using kerfing and the TEBM65 drivers was my intial attempt at getting something that looked like them, but didnt have anything side firing as the thought of a cross over intimidated me. The Phantom clone was the first build that had the side firing PR's and then the Passives Agressive crossed my path, which in a way sparked this latest wacky rabbit hole venture. I originally was going down the idea of the ND65, with a ND140PR on the side, in a similar enclosure sizing to the PA, but didnt like how they sounded when sitting close in the desktop environment, so looked at purchasing the PA's but almost needed to sell a kidney due to the crap aussie dollar and expensive shipping, so abandoned that. So went down to the garage to see what was available and noticed i purchased the Peerless 830985 full range woofers over a year ago for a project that didnt happen, which apparently has some good off axis response and a pair of the Visaton W130 x2 4ohm woofers.
The idea is to have the 2.5 inch full ranges in a 0.012cuft sealed enclosure and the 5inch woofers in each, 0.07cuft. The FR's should have a F0 of 200hz, whilst the woofer would be around a F0 of 70hz and F3 or 60hz. The port will be designed into the body being a rectangle of 70x7mm, which is the same cross sectional area as the 25mm variant. This would need to be around 220mm long.
I've basically used the first pass from DeZZar and tried tweaking it here and there in Vitriux which is my first attempt, not much had changed to be honest, but more adjusting values to match parts i can source locally. I may need to rethink a few things as based on some of the dimensions of the crossover components i might run out of usuable space considering the size of this build and the choice of woofer.
This will either crash and burn harder than the hindenburg or actually work out, i dont really know.
