My first two piecer was over a parallel pair per side in 2 cuft sealed......talk about midbass slam! Those were truly an awesome deal when they were around. Glad i got mine while the gettin was good.

Originally posted by Taterworks View PostIf you were there at the DIY Dayton where my Whetstones design debuted, not all the driver mounting screws were evenly torqued in one of the two stamped-frame drivers, and two out of three judges noted an audible buzz in one speaker. I noticed it too during later testing, and found that applying more torque to one of the screws quieted down the buzzing. The driver's normal operation was enough stimulus to excite the frame. The job of the frame is to transmit the part of the reaction force from the cone and voice coil that isn't absorbed by the motor's own inertia to the baffle of the enclosure, and if the frame isn't very rigid, then it will bend, twist, and deform even under a normal music signal.

There's still the law of physics to consider, and a reasonable size box sacrifices a lot of low end if you want even higher sensitivity.

Funny thing is, I've started construction on a very similar system, using the HDS 850439 as both mid and woofer, with a pair doing woofer duty. I'm sure they won't have the same low end that Paul's 10" will, but it should be interesting to hear them both in Iowa, eh?
I like it Paul. You always seem to get the most from the drivers you use. Can't wait to hear them.

I like the idea of active eq though. How about one of those 4x100 sure modules and a two way analog eq...
I know, defeats the simplicity part...

Originally posted by Paul Carmody View PostActually, both the woofer and mid have a stamped frame. And the fact that the mid has a stamped frame allows for it to be surface-mounted (they're desined to look nice surface-mounted). I recognize that the higher-end Peerless drivers have certain technological improvements, but I don't feel like flush-mounting that thing with its cast aluminum, truncated frame... neither would most builders.
Stamped-frames are not that evil.
As for the woofer having a stamped frame, I didn't say anything about the woofer - I specifically mentioned the mid driver, because the frame is being excited much closer to its natural resonance, and that's why you'll be sacrificing detail and openness with the stamped-frame mid. The whole "stamped frames aren't so bad" meme only applies to bass drivers, which aren't exciting the frame near its own physical natural frequency.

Re: Next up in the shop: a LOUD, paper-cone 3 way
It came off as pretty critical and sarcastic, particularly given Paul's existing designs. Also that you were attaching a lot of significance to the "classic paper sound" comment. The design objectives seemed clear to me. It seemed to hit some hot button of yours.

As for driver cost - I find little correlation with driver performance vs. cost. You can find $30 5"-7" mids that are sufficient for top notch high end performance if you pick carefully/wisely and you can find $500 drivers that are essentially crap. Today, a great speaker system has more to do with competent engineering/design/execution, not driver cost.

Why not try out the new NE25VTS?

Originally posted by Thomas Brown View PostYou know, Paul, you post a really cool design using drivers that are about $100 per speaker ($200 per pair) and people immediately start pooping on it. Now I'm guessing if you where to use some of the "holy grail" drivers, maybe there would be less pooping and more praise, quite possibly the complete opposite. After seeing the pictures of the "swopes", checking out your website, I think this is a great idea. A "throwback" (for lack of a more technical b.s. term) with a really cool cabinet design. With the cabinet design, it leaves tons of options for finishes, As soon as I saw them my mind started turnin'. I am sure the final design will come out fantastic, I would be proud to build and own a pair. Not everyone can afford, to spend $100+ on a single driver, and some of us can't jump on the buyouts due to $$ flow. Here we get looks, affordable (in its relativity), a little bit of a challenge in cabinet making (again in its relativity), and drivers that might be around for a little while. Just a horrific idea! :rolleyes:
Anyways, I am subscribed to the thread and looking forward to someday, enjoying the "sound of paper" with Ride the Lightning on vinyl playing at ear bleeding volumes, possibly distorted enough to blow something up (and not have to pay out the ar$e to replace said blowed up component).
edit: Seems I type slow and so has some of the poop flow.

I love the design, and I am actually going to do something very similar, using the Swopes, sitting on RSS315HT's.
My early design is eerily similar in angles too.
