Cheapest Full Range 20hz - 20khz Speakers?

[Logan_Nolag]

Does anyone know what the cheapest pair of full range 20hz - 20khz speakers there are? It seems like pretty much every speaker I've ever seen that can do the full audible range without a sub costs tens of thousands of dollars.

There has been some discussion on this topic:

There are a number of speakers under 10K that claim to get into the low 20's. For example, the Tekton Double Impacts ($3K) claim to get to 20hz. But honestly, I think most decent subwoofers that can actually produce 20hz start around $500, and that is a unit purpose-built to hit those low frequencies. The fact that a full range speaker costs a lot of money shouldn't be that surprising.

It's confusing when seeing the term "full range speakers" which implies full range single drivers but I'm not sure that's what the OP intended.

FWIW the Lowther DX3 full range single drivers are rated at 30-22000 Hz.

Also take into consideration that there's not that much musical content below 40hz.

Man, I wish I could hear that high. As any of us get older our ear drums harden and we simply can not hear in the 18khz area we can when we were 20. online hearing test are all over the net. find one and prepare to be disappointed.

Yup. I am surprised after so many years working around loud machinery I can still hear to 14khz. Just barely.

Producing the full range is one thing. Audibility is another. It takes a lot of amplifier power and large drivers to produce a 90dB 20Hz tone. Some sub woofers can do it, but if you're looking for a three or 4-way it's gonna cost you, period. And you'll need a big bucks amplifier capable of generating a lot of current.

KEF 107's are rated 20Hz - 20kHZ. They can be found used from $1,000-2000. Only problem is they are not getting any younger, and may or may not need rehab (I bought some already restored). A real bargain if you can get them at the low end of that price range. I can't see doing it any cheaper, honestly.

My Legacy Focus are rated down to 16Hz (can't recall how high...maybe 30 kHZ?). They typically start around $2k, used.

They are the only two pairs I have that go 20-20. That's why I use them for home theater/music duties in the "TV rooms."

For music only, I am using Tannoy Arden. They go somewhere around 35HZ - 30 kHZ.

I don't find I need that low, low end unless I'm doing movies too. But I don't listen to super bass-heavy music either. The Arden at 35 HZ is plenty low for the music I listen to.

Another thing that's almost always left out of the specs is distortion. Very few speakers that go low do it cleanly.
