Using two EL70s

[jamikl]

If I was to build the EL166 MTM MLT crossed low with one EL70, could another one still be used on top as shown in the mini tower of chrisb to get the efficiency/sensitivity up a bit. They would have to be in series as impedance would be too low paralleled I think.

I ask because I wish to build something in this format but not necessarily using the EL166 as I have not heard any comment as to how they sound. I may end up sing something a little bigger than the EL166, just looking around now. Might be early days yet to get an opinion on them.

Two EL70's in series work well. I run them that way in my Coniston^2's with a 68uF cap across the second one to filter the highs away from it. In a proper box they are surprisingly capable drivers set up this way. I think with the cap trick you could mount them both on the front of the cabinet.

microTower. A miniTower is a 12"x12"x48" box with a 6.5" driver (& tweeter) on each face.

You have seen our EL166 MTM with FF85KeN? EL70 is pretty close in efficiency to that driver.

Here is a thread on AudioTalk where Toppsy has done the EL166/ERT26 2-way. I've only used EL166 up to ~300 Hz. In Scott's ML-TL they work really well.
