Hey all !!!
I recently picked up some Infinity Reference Five’s. They look amazing, and sound pretty good!
The foams were redone by the previous owner, but I don’t like the way that the mid’s foam was done so I’m gonna redo them myself. I think the foam wasn’t fully glued on and is leaking air.
Anyways, I’m planning to do several modifications to make these sound less boomy. To my ears right now, they do. But I think that’s partially how these were designed.
Anyways, I was hoping that if any of you have had experience working with these speakers or something similar then you could give me advice on whether or not what I’m planning to do would be a good idea? :-D
1) I’ve been reading up on what other people have done to vintage cabinets and they generally say that they are underbraced. So, I’m planning to use five 1x1 pine wood braces linking the front and back and both sides. I don’t know how much this will help or if the effects of this are placebos or not - it seems like it wont be and might tighten the bass. The cabinets vibrate a lot when playing music with an emphasis on lower frequencies, and when this happens the lower half of the driver tends to vibrate a good amount. Also, what would be a good glue to use here?
2) I’m planning to use duct seal to dampen the frame of each speaker. Would this be worthwhile in this kind of cabinet design? Previously I’ve done this on a speaker with a passive radiator and that made the speakers sound really nice and tight.
3) Should I also use armacell insulation tape around the edges of the drivers + crossover to seal them in? The foam on these seems pretty flat - I can’t imagine they would provide a good seal
4) Finally, should I mess with the crossovers or leave them be? I have a pretty crappy multimeter but I got some weird readings from a certain resistor on each of the boards. On one board, a 2ohm 5j resistor measures at 1.8 ohms consistently. On the other board, the same resistor measures at 2.6 ohms. I think this resistor is tied to the mid driver. I don’t know if I’m doing the test wrong, but if those measurements seem weird should I replace the resistors? Or, god, should I replace both the caps and the resistors? Would this help me out at all or would this be a waste of time? (I think these are from the early 90s, so about 30 years old now)
If you read thru this whole thing - thank you so much !! ive been lurking here for a bit because I want to make a pretty good sound system comprised of older + less expensive parts. you’ve all been really helpful to give guidance and direction of what the hell to look for hahah. Thank you <3
