The Tang Band W2-852SH
​
We're into very high end here folks (tongue in cheek)
Cost was less than $20 CAD each, bought on sale at www.solen.ca for like $10 a piece.
If the datasheet is accurate, with a 86 dB efficiency, some low QTS, a reasonable frequency plot and a FS of 160 Hz. It could work in a horn.
I had to try to horn load it.
​
Could be a nice 2-way system with a pair of 12" crossed at ~800 Hz
For watching TV, this would suffice, as it's a TV speaker after all :)
fit in center best I could
consistent time domain measurement with this horn (compared to when used with 4" VC compression driver)
fit in center best I could
I used the Eminence H2EA horn to mount the TB driver.
​
H2EA Horn is exponential with 2" throat entry (60 x 40 coverage)
The cut off is 700 Hz.
Match should be good
​
As per speaker datasheet, there is some anomaly above 14 kHz. Ideally, they would need a tweeter at ~7 kHz)
​
Results are interesting.
I need to try a back chamber before I give it a listen.
Seriously, I WILL listen to this cause, as I've been bored lately.
duck seal
just barely adjusted to be somehow flat
Like Edison once said : "I have not failed. I've just found 10,000 ways that won't work.”
Update: Day 2.
​
Just in case you’ve never seen an idea take off. How about this? I horn loaded a cheap TV speaker on a horn designed for PA use, and normally used with a compression driver.
​
There must been a reason for nobody using this.
Because it’s not working. Well… not satisfactory at least.
​
Subjectively, it does suck big time. No matter what music you play, it hurts.
​
Very veiled, colored and kind of hopeless really.
No miracle cure… even with a DSP, the sonic are poor.
The speaker cone breaks up above 10 kHz making all cymbals sound exactly the same and unrealistic.
​
I could go on and on describing the lame sound, but it’d be a waste of time, you get the idea.
​
I did try to listen to the set up with the horn playing @ 700 Hz – 20 kHz
​
I put a new measurement but ended up wasting 3 hours of my time. And that was that.
