more really a question for the Multi-way forum, but the question should be asked - for use with which other drivers & at what approx XO?

No sense in our recommending $1000/pair alnico horn tweeters for a pair of $150/pair full range drivers. Good is a relative term. Until we know which drivers they will be used with (and at what Xover freq), we will not know how 'good' they must be.

So, give us a little more information. We are always glad to help spend somebody elses money.

🙂

What do you define as good?

Good VFM? Subjective great sound? Low measured distortion?, broad and even dispersion? carefully controlled dispersion? low crossover frequency capability? great power handling? good looking cosmetically? controlled breakup? extended frequency response (which is great on paper)?

To go in a passive design to marry with an existing drive unit. If so which one?

I started to buy some tweeters on ebay but I was told those are worthless junk. So now I don't know what to do. I was also told tweeters do not have an ohms rating and they hook up different than speakers. If I can buy 2 or 4 or 8 full range speaker that add up to 4 ohms when connected that is all I need. My amp is 80 watts per channel over kill for what I need. It is also rated 160 watts for a subwoofer. The amp has, base, treble, volume for the music/voice and just volume for the subwoofer. This is my amp eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices I am going to connect it to the TV for watching movies. I have a set of 200 watt subwoofers all they do is add boom, boom, boom to the music/voice I am not to interested in this volume on this will be low or off.

Hello Rocket Man,

Tweeters come in many forms. The type you have described as "not having an ohms rating" I believe is a misunderstanding of piezo tweeters, which don't present a very traditional load to the amplifier. For a home audio system, piezo tweeters are not normally going to be a good choice unless they are very well controlled... best to pass on those unless you have specific reason to believe they are going to be beneficial for the application. Most (all?) other tweeter types have more traditional impedance characteristics and IMO, are better choices all around.

I'm confused now you say you want a full range speaker, up to 8 of them? Doesn't really make sense to me. You have a 2 channel amp, the only "rational" configuration [IMO] utilizing full range speakers here would be a single driver per channel.

General rule of thumb is that if you primarily listen at near field and on-axis, you can get away with a single full range driver per channel. If you listen off-axis, at greater distances, or have many possible listeners at a time, a multi-way system with wide dispersion would be the more appropriate approach. [though there are those who may argue otherwise]

The amp is 4 ohm. If I buy 4 ohm speakers then I need only 1 speaker per channel. If I buy 8 ohms I need 2 speakers per channel 8/2=4 ohms.

I have a high frequency hearing loss I can hear things with ear phones I have not heard in 30 years. As the sound travels across the room from the TV speaker to me all the high frequency sounds are lost, all the following high frequency sounds are completely missing, S, F, Th, Ph, T, sh, ch, ete. The word school sounds like hool to me. Police sounds like Pol. And so on. Some TV programs are worse than others it must have something to do with the movie studio sound editor. I have a very hard time watching Master Piece Theater bits and pieces are missing from every word. Sometimes I can turn the TV sound completely off and get more out of the program because I don't have to try and figure out what people are saying. I recently visited an old college roommate he had a home built home movie theater system that he built from speakers he picked up a yard sales and an amp too. It was so amazing I could hear every sound and the volume was not loud. I want that same thing on my TV.

Rocket Man,

Your solid state amp is not 4 Ohm, more correctly, it is rated to drive 4 ohm loads. More resistance isn't going to hurt a solid state amp. A single 8 Ohm driver just means that your amp won't see as much "load" and in effect, have lower maximum output (a couple dB no big deal usually).

You do not need 2 tweeters wired in parallel, in fact, using 2 tweeters on 1 channel is generally considered a major no-no from a sound quality perspective.

Based on your hearing issues and desire to get the highs through to your listening position, I highly suggest a compression tweeter and horn. You'll get more sound where you want it and less scattered around, and be able to achieve higher listening levels with lower distortion.

Or something along those lines 🙂

To deal with your hearing loss, have you experimented with an amp that has a treble tone control? You may be needing more power in the highs. This is equivalent to a hearing aid. Further if you get some audiometry tests done it may give you a target and indicate whether this problem is a hole at some frequency, or a rolloff of the highs.

Hi,

Its impossible to give a sensible answer to someone who doesn't provide
sensible information. What speakers are currently being used ? Blown
tweeters ? no tweeters ? have they any treble in the first place ?
do they have a c/o ? How big / sensitive are they ?

rgds, sreten.

If the subs are vented, seal and stuff them to reduce boom.

Hearing test have been done about ever 5 years over the past 30 years.

I have no trouble hearing TV with ear phones. Like I said, I have hear things I have not heard in 30 years. The high freq is lost as it travels across the room from the TV to me. My friends system of speakers let me hear sound as good as ear phones I think a few speakers in the room it want makes the difference. Loud sound does not work the high freq is still missing. Sound in the 3K range has to be above 55 db for me to hear it. The only problem with me using ear phones all the time is the wire that funs across the room and if people talk I can not hear them, I hear only the TV. I think I can build something that will work all I need is to connect some speakers to the amp and give it a go.

Rocket,
I suggest you go to a Hi-Fi specialist, listen to a quality system or two.
Explain to the dealer that you will probably favour Speakers with a brighter balance due to hearing loss.
Listen to the Speakers they have and try to determine how much of the problem is down to your hearing issues or your electronics set up.

Look at where your friend puts his Speakers, the dealer puts his Speakers, compare this to your own set up. Are your Tweeters actually working? Do your Speakers actually face you?
Presumably your Speakers are not positioned on the floor, like a typical old 1970's set up?

If using surround sound Receiver check if you have this in the right listening mode.

Although highs will be reduced in flight, this is quite minor and is compensated for by increasing the treble level.

Is it also possible that they are tilted with regard to your listening position? Or miswired, or not functioning properly?

re:'My friends system of speakers ' - so what brand/model is this system?

re:'The only problem with me using ear phones all the time is the wire that funs across the room' - wireless, open back headphones might be the go here

My friends system is a home built system. He found a used 100 watt per channel transistor amp on Craigslist. He bought several speakers at yard sales and a couple on CL. Then he hooked them up. The IB subwoofer is under his house attached to a hole he cut in his floor. He said the second speaker he tried for the IB subwoofer sounded best. Then he experemented with his other speakers trying them one by one then using only the ones that sound best. He has 5 speakers one is the IB subwoofer. This is all I know.

I have a couple of full range speakers that are 6" x 8" I think they are rated 30 watts each. I have 2 12" speakers, 2 10" speakers rates 200 watts each at 4 ohms, 2 8" speakers 2 6" speakers, and several smaller speakers. No tweeters. I don't know anything about the quality of these speakers most of them are not marked.
