Default What's the affordable 100dB+ Fullrange driver ?

Beside Fostex can you guys recommend any fullrange driver that has 100dB or more sensitivity ?

I saw China brand but not quite 100dB, I have 0.8Watt Amp tube ... so I need this to replace my broken Coral 100dB speaker.

I hope somebody already make one !

thanks
cal

Two questions:

1- Define "affordable" - everyone's definition varies on this one.

2- What is your current amplifier? tube or solid-state? - possibly a way to increase it by a few dB and open up your options a bit.

Regards, KM

You're not asking for much...

Nothing Lowther make meet that. The DX3&4, & the PM2 & 4 get closest, at around 98db 1w/1m, and they're not what you'd call affordable. AER claim over 100db sensitivity, but they're a) just as expensive, and b) the claim, judging from the T/S parameters on their own site, is wildly optimistic, at least for the MK1 (I'm not going to go through all of them, checking).

Nothing Fostex make meets that kind of sensitivity either. From the factory specs., the defunct limited edition FE206ES-R gets closest, at ~98db, & the FE208ESigma wide-band driver manages 97db but again, they're not going to be cheap. The regular 8in Fostex units (206/7 & FF225K) make ~96db. Same goes for the 8 - 12in Audio Nirvanas, which hover around this region.

The largest Supravox & Fertin field coils, at the appropriate setting, just scrape it, but you'd likely need a second morgage to get your hands on these, to say nothing of very large boxes.

I got the price from emailing Katy Fertin some time ago

Ofcourse its fore the standard LB12 and not the fieldcoil...I also got an offer of 1200EUR fore 4 drivers

BEYMA 12AG100 could be a more affordable and interesting 12" alternative, but I am not sure if its still available as it doesnt appear on Beyma site, but only at Breitbandlautsprecher

Calico88, I see now that you may not be in EU ???

$59 USD and 97.7 db 1w/1m (an honest 97.7, in most companies terms, it would be higher).

Here's a project with it:

As you can see, you'd need a big box (maybe an OB?), a notch filter and a super tweeter (I hear some pjanda1 guy even has a pair like those in the above link on ebay right now. At db/$$ though, its got to be the champ.

Eminence Beta-12LTA 12...

More and more i am warming up to this driver. Seems like a full range veteran. Question, how might this driver compare with the non wizzer 12 inch Eminence drivers? I have been considering a project using a non wizzer 12 eminence plus compression tweeter crossed over low (1.2 to 1.5k) vs the 12lta with a super tweeter crossed much higher (around 7 to 9k).

These types of speakers are interesting to me:
