Martin Logan's Prodigy

The Stereophile review was shoddy. It failed, as I recall, to compare the Prodigy's directly to other speakers and seems to have been written in slap-dash fashion. I found it uninformative.

I don’t know if I qualify all that well to comment on such a topic, but here goes.

First off I do not own the Prodigy’s, but a close friend of mine has had a pair for about 4 months. I have been fortunate enough to be able to listen to them for hours upon hours with both music and Home-theater during the past four months. Over the weekend I had a conversation with my friend about my recent experiences in auditioning some Classe amps at a local dealer paired with the ML Prodigy’s. I told him “Had I been there to buy a pair of Prodigy’s I would have been very disappointed”. With the set up they had Classe CAM350’s, Classe SSP-75 I thought great set up, but to my surprise the Prodigy’s sound was thin and lacking detail no bass slam. I was concern that the room acoustics were inadequate due to some recent re-construction taking place. (I.e.: The front wall behind the speakers was just un-taped sheet rock). Obviously there were some flaws. I don’t think I could attribute the sound to just that though. None the less I walked away disappointed with both the amps and the speakers. Especially knowing what I know.

At my friend’s house the ML’s matched with a Classe CA401, Theta Casablanca II for Home-theater and Bluecircle tube preamp for music. The music the ML’s produces is amazing. Very airy and transparent with very good slam when needed. His dedicated room is on the second floor, which allows for a raise floor instead of slab floor that the dealers use. This I have found to attribute quite a bit to the lower end effect of a system. The ML’s sounded great in Home-theater applications as well, but then again the remaining system has a lot to do with it.

Also to answer Gerry’s question about using a Velodyne. My friend uses two HGS18’s in his big @22WX34 room. Just for kicks we used them in music mode. Even with the volume levels at 2 the bass was bit excessive, but controlled. I really feel that with the 800 watts@4ohms coming from the Classe 401 made the ML sound awesome.

Just my .2 cents.

I have yet to be truly impressed by any of the ML hybrids. Macm hit the nail on the head regarding the CLS/Genesis combo. Lots of panel-- lots of fast, articulate bass. I disagree with the comment about "any good subwoofer will do", however. Been there, done that. There are some very good subs (like the REL's, for instance) that just couldn't cut it with CLS's. Not fast enough, and they do not lend themselves to the correct positioning... *not* behind the panels, not firing downwards. The optimum subs for a home-brewed mini-Statement system are the Kinergetics SW800's and SW800C crossover with Compusound software -- subs and crossover designed specifically for the CLS, (saw a pair with the amplified version of the SW800C for sale here on Audiogon for $3000). I imagine there are other fast, front firing sub towers that can be positioned correctly just outside the CLS's (Infinity?). Another benefit of this type of set up is that you can just run your IC's from the pre to the power amp (bypassing the crossover) and run the CLS's full range for smaller scale, more intimate music. Try that with a stinking hybrid ;-) There is some loss of transparency, even with the Kinergetics system, so it's nice to be able to have the speakers do what they do best with little hassle.

Howdy, Jim, I am still looking forward to hearing your CLS/SW800 setup some day...On to topic: Prodigy bass. I heard Prodigy's at my dealer and the most striking thing about the panel/bass integration was that it was familiar. Familiar in that I recognized the sound from my own listening room. I went through the same type of break-in with my SL3s. Prior to being fully broken-in, the bass went from anemic to boomy. Compounding this change, I was dancing the speakers around on a seemingly endless positioning hunt. A nudge here and a scoot there and--yikes! I'm going from major suckout to mammoth reinforcement!

Anywho, when the bass drivers finally wore in, I found the bass response less placement sensitive. I can still get a boomy-boom-boom if I want it (don't), or a light tap-tap (don't want that either) just by moving them a few inches. But, when positioned correctly, the bass to panel transition does not draw attention to itself. Certainly it is not as seemless as a single driver, but, what is?!

For the record, I have heard from "them" that the panel requires virtually no break in. The driver has a certain tension that relaxes so gradually that the change is not anything like the change noted for dynamic drivers. The electronics driving the panel, well that may be a different story.

That said, I'm going back to listen to the Prodigy's at the dealer--it's been a couple of weeks...hmmm...

i also have prodigy,i m at around 200hrs.still very boomy and no detail bass and very bright highs but i got the same problem with amatis ,i spended around 500hrs to get right sound from them.be patient.
