PSB 50R speakers, just arrived

I picked up a pair of Paul Barton's 50R speakers yesterday. These were well regarded 8" woofer and 1" dome bass reflex speakers from the mid eighties. The drivers are from Philips and the woofer's need to be refoamed.

Pictures will be up once the work is done.

EPI T/E 100 cabinets with AR4X CTS Alnico woofers and CTS Phenolic Ring tweeters

I have accumulated enough free speakers lately that I managed to create a nice hybrid system.

I am a  fan of EPI 100 speakers but never really liked the EPI T/E100 speakers. So the cabinets got swapped with 8 inch CTS Alnico woofer that were found in AR4X speakers with a pair of CTS 2T2 Phenolic Ring tweeters. I changed the crossover to a first order 8uf cap on the tweeters and the woofer just rolls off naturally as per the organ donor  they came from, EDS 1000.


I am really impressed with the sound, I tried a pair of CTS 2T8 tweeters but found their output was to brash for the 8 inch woofer and swapped back in the CTS 2T2 tweeters.

Fabulous combination.......

Update: I moved the crossover point to 3000hz by making the cap a 6.7uf instead of the 8uf value. It has helped out in the the midrange but I still believe a 5 watt 10ohm resistor still may be needed.

1974 Audio Magazine's Audio hifi handbook

Pretty cool score today at a thrift store is this 226 page complete reference guide to vintage hi fi circa 1974.

"a complete reference guide to all hi fi and stereo equipment including prices, specifications and comparisons"

This magazine is in great condition for it's vintage and full of great articles.

Energy ESM-2

I just finished this pair of Energy ESM-2 speakers today.

These speakers were a step own from Audio Products International flagship speakers the Energy 22's. They look very similar to the Energy 22's but no where near the same build quality or sound stage.

These speakers are well braced on the inside and I added a bit more dampening materiel when I put them back together.

Of course the crossover got a new polyester cap at the same value but with closer tolerance and the woofers got new surrounds. I am breaking in the speakers as I wright this post and I absolutely loving these speakers.

I had a pair of Energy ESM-3 speakers in the past and I am no fan of the Vifa D19  tweeter and found that pair fatiguing, this pair of ESM-2 speakers is outfitted with a pair of Vifa D 25 TG which are much smoother.

The ESM-2 is a nicely balanced musical loudspeaker, the sound stage is three dimensional  with great imaging. This pair of speakers is worth restoring to original or better spec if you come  across a pair in need of rehab.

Advent 5012

When I went to pick up the ADS L420's a few weeks back the seller threw in a pair of Advent 5012's for a reasonable price. They needed work though.

The Advent 5012, from what I gather are the last rendition of the large Advent and the best with the soft dome tweeter. These speakers are large, larger than the Pioneer HPM-60's and larger than the JBL L26's.

These speakers needed a re foam on the woofers, bracing on the inside cabinet, sanding and a new coat of Minwax and crossover work along with new speaker terminals.

Here is how they ended up.

So far I have really enjoyed these speakers, the 10" woofer goes as deep as the JBL L26's I just recently had but the dome tweeter just images way better.

I have read lots of stuff on the Large Advent and the consensus is this is the best out of the lot.

I did do a few tweaks tot he cabinet and installed a brace at the weakest point of the front baffle.

I tried changing the 7uF and the 32uF series cap into a single 5.6uF but found I was blowing the fuses, this aspect of the crossover still needs some work. My best option is sourcing polyester caps of the original value and going the series route.

Update: I have since returned the crossover to the original cap values in series using polyester film caps (7uf) and a Solen electrolytic cap in the 33uf value. 

This is the third pair of Advent to date, I once had a pair of Advent 2/W's and a pair of 2002 of which I swapped the EPI tweeters for.

Woofer re foam

B&W D5 Speakers

I picked up a pair of B&W D5 speakers on speculation that they might turn out to be incredible gems and I was right. These are the entry level B&W speakers modeled after the DM5's but only smaller and do they light up the room.

 

Diminutive in size but not is sound, they give my ADS L420's a serious run for the money and actually sound a little sweeter. The size is quite small but the bass is completely full and the stereo imaging is spot on, these really are a loudspeaker that will be staying for awhile.

The real teak cabinets will get a make over and if I find any electrolytic caps in them I will replace them. I paid the upper end of my budget for these after I found out the seller is an acquaintance, he needed the money.

 

I have had these for a full 24 hours and can not rave enough about them.

dB Plus 440 Monitors

I picked up this little pair of dB Plus 440 Monitors a few weeks ago, they were offered up pretty cheap due to the fact that they needed a re foam.

These are made by Audio Products International, the same guys that did the Energy 22 loudspeakers. In fact these have a similar  look as the Energy 22's if they were shrunk down in size. Mirror imaged and the cosmetic ring give it the look and pretty decent build quality.

These speakers seem to be made for the digital era with an efficiency rating of 94db's, this makes them go very loud. The tweeter is reminiscent of Infinity's Polycell tweeter.

The 6 1/2 inch woofer does not go floor shaking deep but has decent enough bass, the mid range is smooth and the high end does sizzle.

This speaker would probably match up well with a low powered tube amp.

Aesthetically I removed the above badge from the front of the speaker and attached it to the rear to clean up the front baffle, I think it looks way better now.
