Eminence Acquired by B&C

@kipman725 I still feel most people want dual 18s these days compared to 21s. The 18sound 18NLW4000 is a great 4" VC driver. Not as all out beefy as the 18IDS, but a bit lower distortion and slightly more efficient.

I'm not a fan of aluminum VC wire. You need really good heat management with it, as it fatigues faster with temp cycling than copper and power compression is a bigger issue with it. Copper VCs will deal with temp abuse more reliably even though it makes the VC heavier.

I am aware. But how bad can it be. The drivers are used in a bass guitar amp with a 40hz claimed response in a 212 config and 32hz in a 112 cab. If I cut at 250hz to a midrange I’m sure it will be ok. Sure I can add a 18” sub to my system later.

I got my edn XST drivers today. They seem very well built I agree with the other poster. Free air resonance seems lower than expected when I tap the cone is resonates like a 808 bass drum which to me is always a good sign for lows. Can’t wait to test it in my heresy like cabinet with ASD1001 in APT150 horn and 1,6kHz xo, I have a feeling this will perform better than the Beta-CX. Tempted to buy more and play around, these tick off most of my “requirements” but it would be nice to have a datasheet.

Do you not own some sort of measurement setup ie DATS or Clio?

The cone looks great for lower mids. Most other 12s in this range use smooth cones, not as stiff as ribbed paper. Could be great with some Aquaplas coating, like JBL does.

You and I agree on the cat and the 102.
As you probably remember, I had luck with rough setup of b102 wide open plus single capped 378 slid back 2".

Still on the fence about to redo that with right sized box and felt covering woof box edges.
I ran 1.4ft3 tuned to 40, while butterworth 4th sims have (since qts .39) Vb=2.3ft3 tuned to 48hz (FS).

My money is that at 10', it would smoke a TB 2145.
Limited tweeter dispersion (couch at 7') but still better than 1 head at 7' (8").

The B102 needs at least 2 cu ft to shine on the lo end. The TSPs make it attractive for a QB3 alignment close to Fs, although its not the most accurate at that alignment compared to an extended shelf. The whizzer cone needs to be removed to avoid the high mid hash which raises Fs and lowers Qts ever so slightly. You can make up for it with some epoxy on and around the dust cap. Don't use JB weld, as its magnetic and will create distortion being that close to the VC.

Where are you crossing it at?

wasn't crossing b102 at all.
5.6uF on 378.

The peak past 3khz didn't bother me 7' away.
Always meant to try to notch it..........

I wonder if you glue a felt dust cap over the dust cap.
I assume the peak is all whizzer.
Cut off the whizzer and I bet it would really climb up (have an increasing response) to 2-3khz maybe.
That's what we saw on fullrange forum when you cut the whizzer off of an 8" driver, climbed to 3.5khz then dropped like a rock.

To me, it was easy to listen to.
Big phase plug might help, might not.
Not the cheapest way though.

The financials are quite bizarre. The press release implies that B&C paid off Eminence's debt at acquisition time ("Details of the transaction released by B&C Speakers confirm that the acquisition of the two companies in US and China was agreed for a value of $4,495,000 (USD), which B&C Speakers financed using its own financial resources. Price paid to Eminence Holdings LLC, is $3,551,000, taking into considerations the companies financial obligations, ")

But the value of a 96,000 square foot warehouse should exceed the value of the entire company, I would think:

"In 2006, Eminence expanded its worldwide operations with the addition of Eminence Dongguan Enterprise Ltd. The 96,000 sq. ft. facility was part of the international Eminence effort to provide loudspeaker manufacturing capability in areas strategically located near manufacturers of musical instrument and professional audio products."

I used to work for Hewlett Packard, and one of the things I noticed about their financial disclosures was that HP nearly functions like a real-estate-investment-trust now. Basically, you look at HP, and wonder "how can this huge company exist on revenue from printer toner alone?" When the truth is that HP owns some of the most valuable real estate in the world. Their holdings are "special" because they're so large and contiguous. A few examples:

1) HP owned a campus near Houston that it acquired when it bought Compaq, back in the 90s. That campus is big enough to land a space shuttle, it's just a ridiculously huge chunk of real estate, in a relatively prime location.

2) HP owned a campus in San Diego that was absolutely huge, located across the street from Microsoft and Sony, and two blocks away from the HQ of Petco. Similar to #1, it isn't just that it's in a killer location, it's the sheer size of the campus that boggles the mind. It's much MUCH bigger than Amazon and Google's puny office, and may even be bigger than San Diego's crown jewel (Qualcomm.)

3) HP owns numerous campuses in Silicon Valley like that

4) T-Mobile's HQ in Bellevue WA may be leased from HP. This is a confusing one: basically, when T-Mobile moved in, they took it over from Attachmate. Attachmate was acquired by HP quite a while ago. But parts of HP have been spun off into HPE and MicroFocus. IIRC, MicroFocus wound up with the Attachmate assets. Of course, it's possible that Attachmate was leasing their building in the first place, and it's also possible that T-Mobile purchased their HQ at some point. I was there when T-Mo moved in to the building, and I distinctly recall dumpsters full of Attachmate stuff getting discarded. But the number of mergers and acquisitions in the ensuing years makes my head spin.

But these are gettins sloooowly sold off. Apple's HQ sits on land that was formerly HP, and so does Apple's new campus in San Diego. I'm not sure who bought the Houston campus, but I heard that everyone who worked there transferred out years ago. The last time I went to the Houston campus, it was practically a ghost town, about 10% occupied. So I'm guessing they spent close to a decade getting their 'ducks in a row.'

HP's gross operating income is largely dependent on its operations in China.
