That old coil looks similar to the one I took out of the audiobahn... What can I use to soften up the glue on the spider so I can get it of the plastic ring?? gotta reuse the ring and don't want to mess it up..

A da sander or release glue it's called un-cure by bsi industries. Over all he's right I think a video of his had spider spacers like 3 bucks lol. Unless your bored it's not worth the time. Also you can try a heat gun. Most adhesives soften with heat. Most being a very key word. An audiobahn??? Really???

What's funny is a company sells a product with issues like the v1s over snug gap and fixes it on newer models but the poor saps that bought the v1 are SOL. At least when Rockville did there optimistic wattage rating snafoo on the K9 they replaced every one no questions asked to everyone that complained, I bet alpine did a better luck next time.
@michaelzernie7092
@michaelzernie7092 2 года назад
Thats not what Rockville did for me. I bought 4 of the K6. Seriously overrated. They told me I'm s.o.l. that's why I now tell anyone who will listen to never buy Rockville

Would you prefer the alpine x over RF power T1?
@RobotUnderground
@RobotUnderground 6 месяцев назад
No the RF is better The type X has problems with that stupid copper vane that's in there. Both of them are overpriced though I'd rather see you get a Skar EVL which performs the same or better and cost a fraction of the price

Please explain to me how inductance doesnt matter on a sub?
@RobotUnderground
@RobotUnderground 2 года назад
It does on a PA speaker because many of them play up to 1 or even 2kHz. However, on a subwoofer, it doesn't play up that high so the amount of the inductance doesn't affect the frequencies that the sub is playing. Many, MANY PA guys have yelled at me over the years but these are the same yahoos that use PA for EDM and recorded music.... And they blow woofer after woofer and pay like $300 for a recone on a $900 18" sub that's NOT MADE for anything below 40Hz... Even if it can play below that, it's not meant for that type of excursion. It's super light so it can be loud and play on the upper end to meet the tweeter.
@noncog1
@noncog1 2 года назад
@@RobotUnderground do you think then that most all subs have an inductance that doesnt affect their impact or transient response at 100hz and down?

@Acoustic_Theory
@Acoustic_Theory Год назад
@@noncog1 You can do the math yourself using a crossover inductor calculator. Put your coil's DCR into the load impedance field. Then adjust the frequency downward until the inductor it tells you that you need is the same value as the Le value of your coil. That's the frequency where your frequency response will be down 3dB due to inductance alone. You're more likely to experience "slow" bass due to mass-controlled roll-off (due to not enough BL) than to be experiencing inductive roll-off in the subwoofer range. What most people describe as having 'slow' bass is actually from not having enough midbass output, because that's where 'kick' lives. Even then, you can't just say "Le is bad" - you need that mass for a woofer to be efficient in making deep bass in an enclosure, so you can't just take mass and inductance off of a subwoofer and expect better performance. You can have "too much" Le in a subwoofer but that's not achieved with most coils that are actually used in speaker-building. In midrange or tweeter speakers, inductive roll-off becomes a more significant factor to control in order to get the bandwidth and top-end response shape you want. In subwoofers, designers will use a shorting ring below the top plate, but that's just meant to try to make the Le curve more symmetrical, not to decrease rest Le (although it does), and Le(X) distortion is usually insignificant in subwoofers anyway so you don't need it. The most musical subwoofers I've ever heard were TC2+ based motors and they had no shorting rings, copper caps, sleeves, etc.
