I'm looking for a replacement 1.5 inch tweeter - Page 3

post #21 of 30
If this speaker will fit I'd get it, for a 2" tweeter it would be hard to beat for $16 each. It's that same tweeter Marantz uses in a few of their old cabinets. If you have time to wait they usually drop in price to around $10 periodically. If you can't wait, they are still a fantastic buy at $16.

That one is out of stock until late May

I figured someone who is an audio enthusiast would pick up on my assumptions, which was that a large tweeter will dip down into the mid range area. That's essentially a place in the spectrum where you definitely don't want a gap.

I can also guarantee I've tested more speakers than almost everyone on this site, not only is audio a hobby of mine, I worked for Panasonic in the speaker department for 10 years, 5 of which I was a tester. I've also done write ups for various DIY woofers for a major website (which they sent me) using a real time analyzer and various simulation environments. But what do I know, my SN is spelled wrong (purposely for people like you BTW).

And what you're doing is over-analyzing this as if these are audiophile quality speakers and he's trying to retain their perfect sound. I also have to laugh that you were a sound tester for Panasonic. Since when did Panasonic make any decent speakers? Oh that's right, they never have. And you waste your time talking about how the "much larger tweeter" is "designed to handle much lower frequencies" but in case you hadn't noticed, there is a sealed-back midrange that's meant to handle those frequencies. This specific driver was obviously meant to also serve as the sole high-frequency driver in a 2-way speaker - that which this is not. I also might like to add that it's a piece of junk and the Fosters are high-quality Japanese items.

As far as your link to the Sony as supposedly being a Jamo driver; clearly they used the wrong images for the Jamo because the specs for it are completely different from the specs of the Sony. The Sony is not a $2 driver and that's prolly why PE "discontinued" the Jamo driver.
APU what?

I'm not over analyzing anything, your trying to save face of being wrong and suggesting speakers out of the blue without looking at spec other than watts. I'll go ahead and tell you, watts mean diddly squat. What you need to be looking at is sensitivity and efficiency. It's not the best option to replace an 8 ohm speaker with a 4 ohm speaker on a crossover that's designed to run at 8 ohms, especially with a speaker that's horribly overpriced like the Fostex that are 40 years years old and made in the 1970's. I'm not even sure the Fostex will play low enough for this set which probably wouldn't matter since they are 4 ohm and would cut off those frequencies being run on an 8 ohm crossover leaving a gap in the bandwidth. Why take that chance when you can match what you have with new speakers that are tried and true like the ones i suggested. I speak from experience, not speculation. The speaker I suggested has usable output down to 800hz which is outstanding for a 2 way tweeter.

It's funny you say Panasonic never made quality speakers, let me educate you. Technics, like the ones in the OP, were made by Panasonic. While i don't know much about this specific set I can tell you Technics did make some great speakers. Your comments further proves your ignorance. Anyway, I rarely worked with speakers made by Panasonic, the drivers I worked with were outsourced and installed in Mercedes in the high end packages. Some of them came from Harman Kardon and Rainbow Audio, a higher end car audio company, so yeah they were of decent quality.

Also, the Sony speaker is exactly what I said it is. It's a overpriced re-badged JAMO crap woofer. The specs are identical, other than watts which is all you seem to notice. Lmao, now that i look it even says it's the JAMO woofer on the ebay page.

It's a popular woofer so that doesn't surprise me. It was probably on sale recently so that would explain why it's sold out.

The only other suggestions I have is full range drivers (which is what I would do anyway). The only downside is they are little more expensive.. Something like a Dayton RS75 , which is a fantastic little driver. Maybe this Peerless driver, or my favorite low cost full range driver, the Fountek FR88EX. The Fountek is probably a little too expensive, but it's the best of the bunch especially at playing the higher frequencies.

Keep in mind you may need to modify your cabinet a bit. Dimensions should be listed in the specs. How big of a diameter is the cut out of your cabinet?

Technics are garbage as well when it comes to sound quality and twice now you've referred to a tweeter as a woofer.

I'm calling you out. You don't know anything about sound and you're lying about working for Panasonic and Mercedes and you're lying about your screen name as well. You only wish you purposely spelt it improperly.

Just stop, you've proved your ignorance. Now you're just looking childish. My god why do people have to stick their chest out anytime they are proven wrong.

..................................................

I just want to point out that not only is it a bad idea to be recommending tweeters without extremely specific specs, but it is also a really bad idea to boast about how you work with speakers when you turn around and call a tweeter a woofer. Both of you are right in some areas and then completely off in others.

First off Technics isn't too terrible, and for 20 bucks, heck even I would have gone with that deal. Technics was a very yin and yang company. Sometimes they had great stuff, other times....not so much. Chances are that these speakers are vintage (pre-1990s ((((that is a guess bassed of the design)))) I personally have not had experience with these models) and normally vintage technics is ok and sometimes even pretty darn good. In other words, there is no bullet proof guarantee that these particular speakers are bad.

Second off, in terms of speaker design, swapping out drivers with non original drivers can result in some really terrible sound.

What happens if these speakers were specifically designed for very particular drivers? Chances are that they aren't. In fact Cavi Mike has pointed out that they are essentially OEM tweeters, but on the 1 and a million shot this is a very particular design, the wrong tweeter could seriously screw with the sound. I remember switching out some tweeters on some polk speakers several years ago. I bought the same size, type, specs, and even style of tweeter and it killed the speakers. They sounded tinny and harsh. 2 days later the speakers were in the trashed and a I built my own speakers from the ground up.

Further more you would most likely be replacing a vintage tweeter with a new one...... Ehhhhhh that is a recipe for disaster ( I am not saying it is impossible, but it is rather unlikely that it will work well). Manufacturing processes are totally different now than they were even 5 years ago, so I can only imagine how different it was 20+ years ago. God have mercy on your soul if that particular tweeter is designed differently than the ones we have today because I have wasted thousands on trying to chase down new parts for old speakers and it was a giant crap chute.

So in short, while you could probably get away with getting a new tweeter, I would not risk it. If the drive truly was an OEM, then there has to be thousands of the little suckers floating around for dirt cheap. Simply do some more research and start searching for the part on ebay.

Please, point out any flaws in the posts I made.

As far as suggesting "drivers" without knowing the specs. Well, I didn't. I searched, and found them all the way down to the part list. I even tried to find the crossover schematic to no avail. They were put in many different Panasonic and Technics cabinets in the late 80s and early 90s, and is the sole reason I suggested the first driver as they are well known to be great replacements for vintage cabinets and are of better quality(and probably just as cheap) than the OEM drivers that are used. They play low enough to be used with 2-way systems and have that robust warm sound found in old systems.

I found the original driver straight from Panasonic. The mounting is different, but the driver should be exactly the same. Here is the link.

Ok. First off, you never run resistors to any driver. Sure you can mechanically, but it is a good way to kill sound quality. Even if you get the best resistor on the market, it still is not going to sound as good as having a straight wire to the driver. I have done that with some of my past speaker designs, and it just made the tweeters sound like crap. To me, doing stuff like that is one of those paradoxical "can you vs should you" debates.

I also never said that YOU specifically recommended random drivers. I was talking about the other guy. You at least seems to have figured out that sensitivity is a big issue here. I simply wasn't trying to point my finger and be too big of a prick while at the same time alluding to the idea that someone's notion of driver replacement might be slightly misplaced. ph34r-smiley.gif

I too have been trying to dig through files to find the right driver, and I have certainly not come up with much of anything. While that looks like a pretty different driver, if you say it is the exact same one, then so be it. I hope you are right. smile.gif
