Re: sony buyout

Do you think these would work for a near-field computer monitor set up?

Re: sony buyout

With the Fs around 77Hz and a .973 Qts, you could probably find a buyout driver that will go lower, because these guys probably can't produce an F3 lower than 80hz or so... but then again, if you're pairing them with a subwoofer that just might be acceptable.

Re: sony buyout

if someone can tell me what size box these might like, maybe i could whip somthing up this weekend and give a measure.

Re: sony buyout

Thanks to Mr. Arlis, I have one of these on my desk right now.

First, the good:

1. The cone is very attractive, it looks almost wet.

2. There is a lot of venting around the voice coil.

3. The backplate is bumped, and XMech looks to be around 5mm, maybe a little more. These could probably handle a little EQ to extend the bottom end a bit.

4. There is a mounting gasket on the back side. Is this a big deal? I think so, for a driver in the $1.00 class it is a nice bonus.

Now, the bad:

1. The frame is ridiculously flimsy. Rings like a bell with a simple tap test. I would bet a couple dollars worth of rope caulk would fix that right up, though.

2. The exposed part of the frame is horrible looking. It is obviously made to be front mounted, and then a cosmetic faceplate of some sorts would be snapped in place over it.

3. I ain't gonna nitpick any more about a 5-1/4" driver that clocks in under a buck - these are cheaper than a side of fries.

I am going to say these were meant for one of those space shuttle looking "all in one" boom boxes Sony and JVC have been selling for years now (you know, the big, ugly things with lots of chunky shapes, a big dial right in the middle and 258 lights).

Looking at Arlis' initial measurements, it looks extremely useful as a midrange/upper midbass driver. Roman mentioned that the ringing at 5k might be related to the frame, but the cone is on the stiffer side, so it may be that as well. If it is the frame, a rope caulk addition would smooth it out considerably and this could be paired up with pretty much any tweeter - like the Nuance buyout stuff. Honestly, tapping on the cone doesn't give me the impression that it is cone breakup causing the ringing - it has a nice, tight "thumpy" sound to it.

I am about tempted to throw this in a box with that Nuance Audax clone tweeter and see what happens.

In conclusion, not bad at all. Way better looking than the other Sony buyout woofer, and the motor seems forgiving of the bass knob with decent XMech.

With the addition of a simple MDF ring as a face plate, it would look pretty nice as well. I don't see how a budget builder can go too horribly wrong with it.

Re: sony buyout

I appreciate that there are those willing to critique these.
Based upon comments like:

The frame is ridiculously flimsy.

and

I'll pass thanks

Re: sony buyout

Yeah these aren't meant for critical listening just as a fun inexpensive project. If your nephew needs some small speaker for his MP3 player. These combined with a T amp and a little work would be perfect. Or if you need a small set for your workshop...... I think the fun is that there is really no cost involved (what with 30 drivers for under $20) paired with an inexpensive tweeter it is all about the process..... and not trying to compete with higher end projects. I don't think anyone playing around with these plans on hooking them up to their Krell or Classe amps and inviting friends over......

Re: sony buyout

i wonder if they could be rear mounted with a nice roundover? somone should really do a line array.

I am very tempted. I have 16ft ceilings in the shop. Will do some calculations today.

I've been seriously thinking about this as well. Any suggestions on a tweeter and crossover/eq?

Re: sony buyout

someone posted in the original thread somthing like 100 tweeters for 85bux. i dont know if the best way is with just one or a few tweeters, or if the one on the pe catalog with a bunch is the best way.

Suggested is to limit CTC spacing to one wavelength so with a driver of this size it will be have to be lower than xover used with smaller drivers.
