Default Suggestions for Open Baffle Driver

Sorry if this as been asked and answered a ton of times -- searching is not revealing much. I am looking for a driver for a pair of open baffle speakers. I would prefer new production, something I can get at Madisound or PE, and if I can keep the price under $100 per driver that would be ideal. I am not planning to use seperate subs, so bass response should be decent. I am, however, willing to add an extra tweeter, so suggestions there are also appreciated.

My amps are 300B based (about 7 watts), but I don't listen to music loudly, so efficient is good, but super efficient is not necessary.

Thanks,

-d

Default a couple of suggestions....

consider one of these:
beta 10cx

Vas is big enough, I think. It's a coax from Emminence, $70 each (not sure if you must buy a cross over..)

and please build the JE Labs baffle, it creates an incredible amount of bass.

I did put a full width "top" on it and a full width "back brace" near the floor as well.

You might consider the Silver Iris.

http://www.hawthorneaudio.com/drivers.htm

I have not heard them, I have no relationship with the dealer, but I have read some very positive comments on other forums. Having just completed an OB project, I like the idea of a 15 inch driver. They are very tempting (my wife is going to kill me) and not that far outside your budget.

Hope that helps,

The silver iris may, in fact, be a good choice. I've purchased a pair, but I haven't found the time to get them up and running yet. I specifically chose them for their high Qts (0.91, I believe) suitable for an OB.

Other candidates that I considered (and may be better for all I know) include the CSS FR125 and the Visaton B200. But, the silver iris should have better bass response, possibly at the expense of midrange accuracy and detail.

You might also want to check out the driver discussed in this thread:

Good luck.

I'm pretty sure this price does not include tweeter or crossover. Adding those will put it pretty close to the introductory price of the Silver Iris. Depends on if you prefer a 10" or a 15", though the Silver Iris is designed for OB.

Thanks for pointing this out. I may give it a try. Certainly looks easy enough and is an acceptable size.

Default thanx for the info, Mr. Ebert..

and the clarrification. Like I said I was not sure if additional stuff was needed.

In my case I used a pair of Oxford J12s, + a tweeter from an old set of Missions, xover from an old set of Wharfedales.

yes the Silver Iris seems like it may offer a better "deal". It sure looks like an Emminence (perhaps made for Hawthorne or modified?)

Default Beyma 8AG/N

Last weekend I have heared the Beyma 8AG/N, a 8" Fullrangedriver, in an open baffle, no xover, no notchfilters - sounded really nice - and it's quite unexpensive, at least here in europe.

The silver iris is a version of the Beta 15CX custom made by Eminence for Hawthorne. The standard Beta 15CX has been discontinued. The tweeter is also made by Eminence. The crossover was made by another party and is, presumably, better quality than what Eminence usually sells. Hawthorne may modify these prior to selling them (I don't know). My impression is that they are quite well made, in a sort of 'professional driver' way. That is to say, they don't have the 'coolness factor' that a Seas Excel or Accuton or a Fostex Sigma series driver might have, but they look good in their own way.

I'm hoping to get a baffle made next weekend.

dsavitsk, can you give us a bit more information? How low would you like the system to go and how big a baffle are you willing to consider? Those two parameters are the basic tradeoff with an OB.

Thanks for all of the suggestions. Sometimes it just takes a few suggestions to figure out what to search for to start the learning process.

A comment on budget: It is not a hard limit. I just wanted to express that people could suggest things above $40, but that I was not looking to invest $1000 in a speaker system. I am not going to quibble over a few dollars, so everything mentioned so far is perfectly reasonable.

Well, I don't listen to church organs or classical, so the lowest notes I need reproduced are those from a bass guitar. My current speakers (an older set of B&Ws) claim to reach something like 48Hz which has always been enough. Lower is better, but if I hit 42-45Hz I am sure I'll be happy. My landlord's bedroom is directly below my stereo, so discretion is in order. Also, I like punchy round bass more than deep bass (which probably seems odd from someone with 300b amps, but they are punchy.)

For baffle size, I figured I'd go with the 31.5"x35.5" from the JE lab site until I knew to do something different. I am open o suggestions, but also don't want 6 feet of plywood in the living room.

I have seen comments on other sites about the B200 driver that Paul mentioned, and people seeming to really like it. Any thoughts? It is not clear if they are using tweeters, or of they are just using a single driver. Also, I can't seem to find a source for the CSS FR125 to check prices/availability.
