Default daniel hertz levinson m1 wow

hi all
i just found some pics of this amazing speaker on the net http://www.danielhertz.com/products/m1
first impression is WOW its big
i wonder how it sounds

i,ve been looking for ages for a design like this to use as a base for my next diy speakers but how would a 12" driver go producing midrange ?

and what about a compression driver for highs ,i know they use them alot in the pro industry but are they good enough for home audiophiles

any way i reckon they look grouse and would proberbly blow your socks off

any oppinions ?

regards sheafer

Looks beautiful and simple. The drivers look like off the shelf pro audio drivers. The tweeter horn looks like it is turned the wrong way. I bet someone on here could tell us the drivers and we could easily clone it using the information they give on crossover points.

saw these, saw the price tag, laughed so hard i shot coffee out my nose.

For the price of these, one could easily purchase an old farmhouse and install a pair of altec a7s with the sound practice mods in the barn.

A real brawl about Daniel Hertz M1 speakers at the Axpona show!!

Agreed about the price.

does anyone actually think they look good?

They look as tacky as you can get in my book.

So I take it you're not going to add chrome rings to your drivers now? I guess you're afraid of being labelled a 'copy cat'.

The blog linked was hilarious.

Don't worry at all what they use, there are plenty of other great units out there from a number of brands.

Not crazy, fairly mainstream for some of us.

It could sound OK, but we'll probably never know.

Geddes uses them (and 10's and 15's) in his designs with good results. I use 10's and think they're excellent.

Yes, but like everything, there are good and less than good drivers and flares. A sane starting point for a CD is the B&C DE250 and the JBL Ewave flare.

Nothing to say
They copied my design
Quite basic : big volume for a big woofer ,which has to be necessarily near the floor to keep efficiency with the mid&tw ; the box being tilted to accomodate the offset of mid&tw ; crossover made accessible to change the parts that's me ! and also mechanically isolated ; port (s) on the bottom front ....that is a big compromise ...I would have had it preferably on the back or on the bottom ,but I choosed to keep it on the front because of my little room and their positioning near the walls.
Ok ,mines are 12"+6.5"+1" dome at 94 dB/W/m and costed me about 300$ ,and I don't think they can handle more than 100W

I've used a lot of PAudio stuff over the years (still have maybe 10 drivers) and it's OK, but generally nothing special. You can do better with other drivers either locally or imported esp with the $ so high.

The 2" CD will start breaking up somewhere after 8-10k so you'll need something above it, which is why I suggested a 1" driver. Good 2" flares are less common and generally more expensive. With few exceptions, I'm not fond of Ti diaphragms.

PS: Wayne's article is also well worth reading.
