My build for the FE108eS:
My Metronome Experience
Note that I made a mistake by lining all four sides of the enclosure and had to correct that. Then I added BSC.

Build for the F120a:
The Metronome
Be sure to read on through p66 #657. My initial experience with the F120a on SS was not favorable. Tubes changed all that.

Cheers, Jim

Forgot about the question of 'quick'. This is not a term I understand relative to FR drivers. Some folks talk about 'slow' bass, but I think what they are hearing is a lack of coherence between bass and mid-range drivers. Errors in phase and amplitude between the true low freqs and their overtones in the mid-range can produce a negative impression.

Cheers, Jim

I'd even choose EL70eN over any of those.

I am sorry if I had brought up water under the bridge. So dave do tell is the mark audios better then the fostex? I really do like the paper sound? Why do you like the make audios next to other drivers? I was looking at the mark audios Aipair 6p but are they better then the chp-70-p drivers? I wonder how the alpair 7 is? Thanks dave again jm

Okey not qucik the drivers respones to move back and forth and beable to not lack cone drag if I am saying right. Also to beable to keep up with all types of music. A quick driver respones and then moves back in to its normal place. I hope I am saying and writing it the right way and in the right terms. Jm

AFAIK FR has always been good (provided the right application and quality of course). It's just that drivers that are easier to use, IE not requiring huge horns, a cm sweetspot if the driver was large, special amp or other particularities, are getting much more common and mature.

Old drivers like Coral, the old Fostex lines and of course Lowther, can still more than hold their own.

During all that follows remember that most of mine (& Chris') listening is with drivers that have been matched & treated.

Warning: long stream of conciousness follows.

Depends. Room, box, amps, taste are all factors. For awhile MA was pulling ahead, then Fostex revised both their main lines. They each have their strengths. If you have a small SE tube amp, the efficiency of the xx6En drivers give them a big edge.

A couple years ago i sent Mark a set of uFonken because the FF85k was trouncing the Alpair5 and Alpair6. I set him a goal of getting better than the FF85K with the next generation.

A recent 3" shootout had both the A6.2p & m did out perform the 85k -- kind of amazing given how good the driver is-- but Fostex hadn't stood still and the new FF85wk is neck & neck,

3" driver audition Fostex/Mark Audio

I really do like the paper sound?
I have never been a big fan of metal cones. Including the 1st gen Mark Audios.The 2nd gen with the unique multiform cones changed that. The Alpair 7 became my favourite driver. The A7.3 is even better (at the sacrifice of a small amount of bass extension). But the EL70 (CSS but made by Mark Audio) is not far behind, with more robust & more extension in the top end, a more relaxed sound, it doesn't have the downward dynamic range but one of the side effects of that is that it is not as ruthless revealing deficincies of the rest of the system including the software -- if you need to rock, or have an HT receiver i'd put the EL70 over the A7/A7.3.

The new FF125wk is right up there in contention (stock vrs stock, 1st treated ones haven't been listened to yet, boxes not yet done)

The Alpair6p does, IMO, give a vinatge sound with a laid back top good midrange and bass that is very unexpected from a 3" (mind you a large one). The CHP70 is not a driver i have heard (Europe & Japan only) . It gets high marks -- check out the accolades on the audioTalkforum -- and is broadly similar to EL70 and of the same time frame (Zia, the only guy i know that has both -- the guy is a recent over the top addict and proud of it), gives the edge to the EL70. The new CHP-70.2 (with gen 3 tech), Mark took the desires of people to have a more vintage sound, and ended up with something i personally feel was a step backwards (look at the FR charts to get a broad idea, big peak followed by deep shelf down). By itself it sounds just fine. Set it side by side with EL70 or A6p and it becomes clear that something is missing -- top harmonics in female vocals for instance. In the milliSize boxes we did this comparo in the A6p is actually the winner, the EL70 sounds a bit constrained -- put it into the larger box that it is happier in and it is clear that it is.

Now, to muddy things further. We developed the microTower as a tribute to Winslow Burhoe. It was always my intention tp eventually convery the microTowers we built to microTower IIs (ie add tweeters to the unused sides). With the CHRs in them originally this would be a receipe for HF pain. With the CHP70.2 the shelved down top can be turned to an advantage here making the MT II make more sense. It would also make sense with some amps, or rooms that are real "bouncy/live"

So it depends ... all these drivers are marking a time when FRs are finally starting to eclipse and improve on the best from the times when FRs were king.

Don't let buyer paralysis take hole, buy something and start playing. Compared to multiway systems they are cheap (money wise, not quality wise)

Questions? Did that make sense? (probably not completely )

dave

Jeff keeps me well bribed so it is hard to put a money value on them. He helped me with some construction projects, i did the drivers he already had in exchange.

To get a pair of treated FX120 add $120 to madisound retail.
