Need help matching receivers to speakers.

[cipherlight]

This is my first post and I do not know much about home stereo equipment. Any guidance is appreciated. I have a Technics stereo integrated amplifier model: SU-Z22 and a Technics ST-Z11 tuner powering two Technics SB-G700. I'm wondering if the stereo amp is enough to power both speakers? or is it underpowerd? I've added links. Thanks

As long as you dont play very loud you should be just fine. When turning up the volume if you at any point think it starts to sound a bit bad or fatiguing turn it down a little. (Where this is differs even within a song so turn down as needed, you might not need to if staying at moderate levels)

No worries, hook it all up and play some music.

Now, don't take this personally, but it's a mistake to worry about whether or not that amp and those speakers are compatible, and would be a costly misallocation of resources to buy a more powerful amp for those particular speakers. All that kit looks like something from JCPenny in 1979. The tuner and integrated may still work, so may be of some utility for a modest rig. Your ears would appreciate better speakers, for sure.

The speakers are rated at 8 ohms which is an easy load for an amplifier. Your equipment will drive them without issue.

My question is: I know that by today's standards, your SU-Z22 is not a powerful amp, but does it sound under powered to you? Does it seem to struggle to drive your speakers?

If the sensitivity of the SB-G700s is 97 dB as indicated on the Hi-Fi Engine site, I doubt that the amp would be under powered, unless you like your music rather loud and your listening position from them exceeds 12 feet.
However, I doubt that their sensitivity is that high. I suspect that it is closer to 87 dB. The higher sensitivity is mostly found on pro audio speakers which have to project sound in larger rooms and venues.

What I suggest is that, if you have a friend who has a more powerful amp, or have access to a store from which you could borrow a more powerful amp, such as a Yamaha A-S501 integrated amp, you could see for yourself if you can hear a real improvement over what you have.

The SB-G700's are pretty bad IMO. I have opened the speaker cabinet up and I see the poor craftsmanship and rather cheap speakers. The sound is rather flat and I should invest in better components but, It's hard to let go of them because of their sentimental value. I appreciate your honesty.

It does not sound underpowered but the highs sound less prominent than the rest of the music. I'm familiar with car audio and the 4-way speakers for cars were always garbage. Does that transfer over to 4-way speakers in home audio as well?

It is pretty hard to answer you. Possibly your tweeters are defective or your speakers were voiced to produce a reduced high frequency output.

I suggest that you take your speakers to a good audio repair shop where they could be listened to and be compared with a good speaker which they have. Or do you know a friend who is knowledgeable about hi-fi stuff and able to answer your question following some testing.

All sentiment aside, it is speakers that determine the quality of sound you get from a recording, not the amplifier. If you want to upgrade, the speakers are the way to go.

It has right and left speaker terminals- yes, it's powerful enough for those speakers. These components were made a year apart and they didn't worry about the minute details that people care about now- I'm sure tens of thousands of people used this combination with good enough results and I'm sure that some tried to crank it too loud, which caused damage to the speakers or the amplifier but at that time, 35W/channel was often enough for most applications and speakers were more sensitive than thy tend to be now.

You need to cover and uncover each tweeter with your hand and listen for a difference- if you don't hear less treble when it's covered, it's likely that the tweeter or its crossover has been damaged. Don't be surprised if you look inside and only see a single capacitor on the mid and tweeters- that was common. If the capacitor(s) look like they exploded, replace them- it means that someone was using too much power (caps do this when the voltage is beyond their capacity). You can test any bad drivers by turning the volume and bass down very low and bypassing the capacitor(s) that was damaged- you need it to be just loud enough to hear something from the speakers. If you hear sound from the tweeter(s) when the capacitor is bypassed, it confirms the idea that it was damaged. Capacitors are often inexpensive, but you would need to look for the label inside, to determine the value needed.
