fostex fe126e in a mfonken?

[dod996]

Has anyone tried a Fostex FE126E in a mfonken?
I'm building a mini system for my niece and I don't want to spent too much on drivers.

not an advisable combination if you don't plan on sub/sat style system - even then the FE126 would have some problems in a enclosure this small

if you don't already have drivers in hand, either the recently discontinued FE127E (still some around) or Mark Audio CHR70 in sealed version would be the most likely candidates

the only downside to any of the Mark Audio drivers to date is their lower sensitivity to which those of us familiar with Fostex have become accustomed - and frankly that's only an impediment with low power amps such as the flea watt SET's some of us enjoy in combination with our single driver systems

FE126e will not work in the mFonken. It is specifically designed for FE127e... If you look at this thread you can see that each specific driver needs a bit different box to work ... but FE126 will not work no matter what i try (the closest curve to acceptable gives F3 of about 140 Hz, and it starts flling at about 300 Hz)

The discontinuation of the FE127 is a big loss to the diy community. I still have a few pair left, but after that... EL70eN is a good sonic substitute (not the same, but on balance), but you do need some 4x as much power (fortunately these are much happier with SS then the FE127eN)

as Dave alludes, there are several models of Mark Audio drivers that work well in this size box (we've tried to date the A6 CHR70 and EL70)

unless your niece will hosting dance parties, amplifier power of e. 20-30W of solid state ( such as a Class T amp) should be sufficient


for the budget your inquiry regarding FE126 implies, the choice between either of the "70" models could well depend on whether you have a known preference for paper or metal

until I hear newer production models from Mark, my own taste leans to the paper (EL70)

Dave, have you ever tried enabling any of the Tang Band drivers, like the w4-1320? It has good sensitivity of 89 db and it's an 8ohm driver which is a plus. One thing's certain, at least for me, Fostex are some of the nicer looking drivers out there. Too bad they're fazing out the xx7's.

I have EnABLed some 3" TBs.

How would a mMar-Kel70 sound using a T-Amp in place of the mfonken?

Tony

[planet10]

They sound fine. I am using the original prototypes in my office. More capable than FE127 in the bottom & top, not as forward thru the mids, and perhaps not the finese thru the midrange -- i'm being reserved about that, as these drivers seem to take just as long or longer than the Fostex to bed in.

T-amp will like that they are 4 ohms.

I know it has more power available when used with 4ohm speakers but isn't distortion a bit worse with the t-amp when using 4ohm speakers?

[planet10]

Measured distortion s typically higher in almost any amplifier when you halve the impedance.

There is little or no correlation with distortion and sonics until you start looking at the spectrums.
