Seconding Tannoy and B&W, the 685s are great, though probably too new to be very easy to find used. I'd look for something like the B&W 601 S3 or Tannoy Sensys DC1.

PSA: If you like NAD amps, don't combine them with Tannoys without listening to the combination first.

That being said, it's not much more than an amplifier with a 3.5mm jack, so you're not gaining anything except a smaller footprint.

Oh hey, that thing is pretty cool.

Not to mention that you can get better amplifiers in them than before too, Class D or Tripath vs a lovely AB with a too small powersupply (because space and heat constraints).

I hate this whataboutism trend

Yeah, it was just too easy...


Well gently caress, that was what I was getting at. I'm bad.

Back to the topic at hand:

At normal listening levels, you'll rarely exceed a few watts of power, and the average power will often be <1W. But in properly mastered recordings (i.e. poo poo that isn't overly affected by the loudness war), you'll have portions of the track that will demand a lot more power "on tap". That's why good amps generally have well thought-out powersupplies with decent capacitor banks and transformers that can keep up with demand.

You very rarely blow speakers by feeding them too much power, but it's exceedingly easy to do with an undersized amplifier if you don't pay some attention to what you're doing. As the amplifier peaks, it sends out square waves (DC of alternating polarity) that will fry tweeters in a hurry. A classic example is the old Cerwin Vega AL1000 paired with a single NAD 216 or 218, where they really need bridged 218's or 208's to survive being cranked to 11.

I have a Trends TA 10.1 t-amp that I've paired up with a couple of Tannoy MX1 bookshelf speakers. The combo sounds pretty good, but you notice when it runs out of steam fairly quickly. Some of this is due to the Tannoys being relatively low sensitivity (87 dB/1W/1m IIRC).

No, this is wrong. Clipping and square waves do not produce DC. They produce harmonic overtones to the base frequency, in other words clipping generates high-frequency content. And square waves do not kill speakers, otherwise distorted guitars and synthesizers would be killing speakers left and right.

What actually happens is that a square wave has ~1.4x the RMS voltage and ~2x the power of a sine wave with the same amplitude. You're putting more than the amplifier's rated power to the speakers, and if the speakers are undersized, they'll fry. Especially if the tweeters are under-specced, as the clipping creates high-frequency harmonics.

But in the end, what kills the speaker is too much power, not the mere fact that the amp is clipping.

For instance, it is completely impossible to kill a genuinely 100W rated speaker using a 10W-rated amp through clipping, no matter how much you abuse it. Utterly impossible.

Good points. I'm rusty on analog electronics :v:

However, the point about harmonic frequencies, doesn't this push more power into the high-frequency domain? and what is the power handling of, say, a soft dome tweeter vs a 15" woofer?
Going back to my example about the AL1000's, what usually happened was that either the fuse for the tweeter blew, or the tweeter itself blew, as it couldn't handle the power being put through them.

Thanks for the info. I have everything hidden away in a central closet in our house so it passes WAF. I figure for $20 apiece, I might as well grab them and figure out what to do with them later. Perhaps use all 3 to power an IB subwoofer setup in the next house. Or, if I can find a cheap matrix audio control unit, set them up for whole home audio distribution via ethernet. Overkill but would be fun to play with if I can do it on the cheap.

At $20 a pop this is a complete nobrainer, buy them already!

1) almost no lower limit, you'll be fine.

2) you set the amp up for the speakers you have, 2.0, 2.1, 3.0, 3.1 etc etc doesn't matter much. Starting with 3.1 is a smart move, the front row (+ sub) is the most important bit for audio quality. The surround channels are cool too, but not as critical, at least not to start with.

Probably? But the bar is pretty low at this point, and you'll probably upgrade later, which brings us to this:

One thing you will never regret is spending the money on a proper sub like an SVS

I bought an SVS SB12-Plus a while back and immediately regretted not just buying an SVS sub when they became available in Norway a few years ago, they knock pretty much everything else out of the water in their price class without breaking a sweat.

This is exactly the thing that makes me laugh about the loving AV industry, it's all a numbers game but the numbers are loving meaningless in most cases so finding a genuinely great product is really hard to do, particularly when speaker manufacturers tweak the figures so much.

Amp A: 3000w PMPO - the output an amp can do for a nanosecond before exploding (also known as; wattage ISL - if struck by lightning)
Speaker B: frequency response of 20hz-20khz - 20hz response is -15db and basically inaudible
TV C: contrast ratio of 10million:1 - test conducted in a pitch black room with the screen off to measure black level, white level only attained for a nanosecond before the screen burns out

So much bullshit.

And people wonder why I just stick with Tannoy, SVS and higher-specced Pioneer* receivers...

*My newest Pioneer is a VSX-1015 that isn't even HDMI, so... I dunno what I'd get now.

Yeah they're not the best bang for the buck by far, but they're the best bang for the bucks you pay for something you didn't make yourself.

I'd really rather run an IB setup or one of those horn loaded subs, but they're hardly viable for a 750 sq feet apartment :v:

I mean a flat pack from diysoundgroup.com and Stereo Integrity HT 18 v2 are probably the best budget bang for your buck if you're willing to go with DIY route. $275 for the subwoofer and enclosure. Then a Behringer inuke 3000DSP for $280. All in your under 600 bucks and have extra amp capacity if you want to build another.

Nothing store bought can come close to it but you're talking about some work and the biggest difference to me is the finish. Putting the flat pack together is easy for anyone but finishing the cabinet in something that looks nice is a lot more difficult for someone without experience.

Yeah, I fully agree with you there.

Sadly, I live in Norway and my options are more limited. I got an SB12-Plus for a few hundred dollars used, it's more than enough for my needs.

The next time I move, I'm probably going for an IB setup with 4 or 5x18" in a suitably sized home theatre room :sun:

Worth trying the SVS SoundPath isolating feet or a subwoofer platform.

Can confirm that these works wonders. One would think that dampening feet wouldn't make a real difference for a sub, but in practice it goes a long way to decouple the sub from the room, thus bothering neighbours a lot less.

I moved from a freestanding house to an apartment block and I haven't had any noise complaints despite rocking it pretty hard at times.

I think a lot of the "ported subs are boomy" came about from cheap drivers and cheap manufacturers. Like if you're going to make a lovely sub you're going to port it just to get the efficiency bump. That doesn't mean ported subs are inferior in any way.

"Tight" vs "boomy" probably has a lot more to do with "expensive" vs "cheap", than sealed vs ported, I guess.

You can compare the driver to a motor and the amplifier to a controller trying to steer the motor precisely.

A cheap driver tends to have a lot of moving mass compared to magnet/coil motor strength and will objectively tend to sound worse no matter what you do in a ported enclosure. You can mask some of this in a sealed enclosure because of the inherently better damping*, but it's still going to be meh when you push it.
The same effect can be observed by pairing a good driver with an undersized amplifier. As you push the limits of what the amplifier can output, it will lose control over the driver and you get distortion in various forms.

*This is my intuitive understanding, it's by no means entirely accurate.

I'm getting kind of sick of my Elac B6 being too boomy when I listen to music. I have a Denon s910w for a receiver . Is it worth it trying to stuff the ports or do I need to step up? I use it for music and movies. Thought about going with a set of KEF Q100s but prices brand new seem kind of insane at 500$. The front port seems nice to me since they would be sharing a wall with the bedroom.

In all seriousness, subs are fine but you should have dampening feet for it. SVS has one type for sale, Auralex also makes sound dampening pads.

But in the $100-200 range, I don't think I'd even bother.
