Looking for pure Mid recommendation

[ani_101]

I am looking for a pure mid recommendation in the 3-4" size. The objectives are
- crossover to tweeter around 5k and woofer around 300. Though in reality, the range might be narrower, especially the cross to the tweeter, but some ribbons/planars like 4K+
- cost less than 100$ each, though around the 50$ mark would be nice
- doesn't need low extension, higher sensitivity would be good, but not necessary

I have a pair of TB 1320SJ new magnet which I can re-purpose, but looking to see if any other mid can provide better performance given the above criteria. So far what I am looking at are:

TB 1320SJ
SB12MNRX25-4
CSS VWR126X

Any other mid that are comparable and should be considered.

Regards
Ani

To cross low, you may need more than 90dB sensitivity. That will largely be dictated by the woofer chosen, and baffle dimensions.

This looks interesting to me.

Zaph's tests of the non-SL model show very damped cone breakup points in the 1 to 4 k range, but its not any worse than the satori driver he measured.

Zaph's distortion measurement of the SB12MNRX25-4 strikes me as not all that good:

I would also consider these:

though I'm not sure how high the Tymphany should be used.

I like the Scanspeak Discovery too, but look at the larger 12W, they might label the 10F a 4" but it's not.

Re: Looking for pure Mid recommendation

10F is advertised as 10cm, it is actually 9.75cm edge to edge of the frame, as most drivers are measured. Actual radiating area is <3" however.

I would choose the 10F over the 12W for midrange application, its flatter impedance graph implies a lower distortion motor, and much smoother response at high frequency. While it can handle 300Hz just fine, I'd recommend 400Hz crossover, and on the high end you can crossover where ever you choose. The 10F/4424 was measured in Zaph's blog, it has amazingly low distortion, and frequency response is a flat line out to 10kHz+. A bit pricey, which is why I listed the 10F/8414 as a lower cost alternative.

Hey Ani , would any of the new , smaller full range tang bands fit the bill? I know you mentioned pure mid , but

Re: Looking for pure Mid recommendation

10F crossed at 400hz can take plenty of power.

I agree. I was thinking the OP only wanted 4" but since he mentioned 3-4" the 10F would be a great choice.

Re: Looking for pure Mid recommendation

Don't know what sensitivity you are looking for, but the Audax hm100z0 sounds pretty sweet and has SPL of 93db. I have one crossed around 400 hz to an AE td10s.

Re: Looking for pure Mid recommendation

I will second the Vifa NE123W. Absolutely great driver. The Scan 10F I have always wanted to try.

Re: Looking for pure Mid recommendation

This one is my pick:

http://www.parts-express.com/tang-band-w3-1797s-3-neodymium-midrange-driver--264-888

88dB at 2.83V, roughly. You may have a small resonance issue at 3k on the 1797, but should be easy to nuke.

Re: Looking for pure Mid recommendation

I keep thinking about a 3-way with this as the mid:

Re: Looking for pure Mid recommendation

might as well throw another expensive mid into the fray.
