Default speaker companies

What companies that are making high sensitive speakers do you recommend? What speakers are you using?

Lately my favorites have been:

TAD, for the big buck crowd,

PHL for the slightly less wealthy

Polydax Pro, for slightly less $ yet

Fostex for the budget minded

Beyma and Selenium instead of beer.




And of course the ever popular Altec 604's

A good list... the 604s also remind us that there is some nice vintage stuff out there. Triangle, and Eminence (as in things like the Adire HE10) should also get a mention.

I would have to add JBL to the list behind TAD, but that’s me. And if you talk about sensitivity, you have to include horns.

I like Triangles too. And don't forget about Fertins (if we can trust dice45).

Brian Cherry's initial reaction to his are also very positive.

Ok Nelson (and everyone else) I've got my Selenium 15" driver for my beery bass.
Now for the higher notes:
Anyone heard the PHL 1240 TWX 7.5" that has a coax tweeter? only $160!!

Zylatron has 'em on their web site

P-10:

How about a bipolar speaker? The PHL 1240TWX (with tweeter) faces forwarda plain PHL 1240 faces back.

The 1240 has 93 dB efficiency, the tweeter is higher.So if I have one forward and one back will the efficiency be 96dB for the 1240's ? Solves the bafffle step issue, right?, but does it also increase efficiency in the midrange also?

Second possible approach: I'm planning on getting a Fostex FE206 to make a varient on the Basszilla (instead of the FE208)
The driver is mounted in an open baffle. Will the PHL 1240TWX work in an open baffle instead? ( with a crossover to the tweeter of course) but I'm wondering if the compliance is good for open baffle. I assume you can't use too compliant?

Ok another question: What if I mount a 1240TWX AND a 1240 in a vertical array facing forward on an open baffle? Double the efficiency to 96 (the same as the Selenium woofers) Does the tweeter being in the center of one driver screw things up? Obviously not a D'Appolito, but the drivers don't have a tweeter keeping them apart. suggested crossover is 3k.

Sounds like a plan.

93 dB measured into 2pi space. As soon as you wrap into 4pi space they go down to 87 dB (ignoring room lift). A bipole would be 93 dB all the way up - it is always radiating into 4pi space. You gain some with 2 drivers in a room.

The Q is similar to the Fostex. Should come close to filling the same role.

You'd have to add BSC so you might as well build a bipole (if your room supports it).
