Page keeps crashing chrome on my phone for some reason? Ahh well. I'm assuming they must be neo magnets then, to me the magnet structure looks like a similar total magnet mass to a double stacked ring, (lots of airspace as opposed to solid magnet), and I assumed with that darker finish they were ferrite rods, but I guess not.
So this makes sense, tbh I think I robbed the s1 number out of a horn resp tutorial lil mike posted once many moons ago as a place to start because I wasn't thinking logically. that was a decent enough tutorial though because I actually figured out a lot more than I had previously known.
I knew this at one time yet when thinking about this suddenly forgot it because I was thinking if I could make something like this work well enough in a small enough container I would make it part of my next bluetooth speaker project and was focused on wiring down to 2ohm in order to get the power from the amp chip I want to put in my bluetooth amp board.
I would do a 2 driver 84L TQWP = tapped pipe = straight flare tapped horn.
This is pretty nice and I may play with it some, originally the idea was to make a tapped horn small enough to fit behind the seat of a single cab 03 ford f150, most conventional sealed enclosures designed for that space give ~2 - 2 1/4, ft3 of air space so even in my modeling I had sacrificed quite a bit of SPL to make it small enough. That guy ended up finding some old junk 12s and I built him the typical sealed wedge.
I appreciate the input from everyone and will still probably pick u a few of these up just to play with. I am currently working on building a new center console for my pickup to house my dual Stereo Integrity SQL12s. Trying to decide if I go from front firewall all the way to rear wall and pick up another pair, second alternator and 6k amp, or just pick up a second 1700w monoblock for my existing pair.
It’s not mine. An internet friend shared his measured TS parameters with me
Nah I think max I could have gotten was around 70L because home boy is like 6'9". maybe if he was exceptionally short could squeeze some more volume out of the space
I see why the enclosure is sealed. All the BR (TL too) and BP6S enclosures are coming up terrible in HR.
I'm going see what BP4 I can come up with.
Something is not right with those measurements. The tuning frequency is not changing in HR with increased sealed enclosure size. I am going to see what happens with the manufacturer's specs.
