Restoring Bozak E-300 cabinets

Hey mrphilco,

Hearing, listening to loudspeakers and what you're psyche wants to hear is so bloody objective. Without having the 200Y's to directly compare to, you simply won't know. I spend all my time here in the Speakers Forum looking at posts that focus on older speakers. From what I've gathered here and in personal observation, so many people enjoy rolled off highs. In fact, your B200X tweeters were born when Rudy Bozak felt that the music back in the 50's simply didn't have any frequencies worth listening to above 10k. I too listen to music that was mostly made back then and into the 60's, but the same genres. I feel that I'm missing some of the presence of the recordings when I compare the rolled off highs to the more modern 200Y tweeter. And even then, for me the Y tweeter is still on the light side. My psyche enjoys a more modern tweeter solution. This is why with my Bozak Symphony project I will be integrating a pair of modern SEAS tweeters to the mix. I've got a crossover that cuts the B200Y's off by 9k, and brings up the SEAS at 8k on up and then caps them at 19k.

As time goes by and you put more and more material through your rigs, you may or may not find the limitations of the X tweeter. When and if you come to the decision that you'd like to replace the X's, the solution is available. The Y's are plentiful and affordable, the crossover to integrate them into your system is available at the touch of a few keys.

Ain't those B199's an amazing driver?

Agreed, yes, the B-199s are superb woofers. And agreed also that listening to speakers is quite objective. What one person finds to be near-perfect reproduction, the next person may feel that the sound is like muddy mush. That's why there were, and are, so many manufacturers pushing their idea of the ideal sound.

Speaking of rolloff...as I type this I am listening to a Paul Weston LP from 1953 (Dream Time Music) that sounds like it could have been recorded in the 78 rpm era - it definitely has rolled-off highs. I would imagine that if I were playing this right now on one of my other sets of speakers, that it would sound more like...muddy mush.

I love these E-300/B-302As so much that I'm already wanting another pair, only a set of Urbans next time. I just missed out on a pair of Bozak Urban empty cabinets on the auction site that sold for a whopping $16.50. I didn't bid because I didn't want to drive to near Pittsburgh to pick them up, but I've been kicking myself ever since. Anyway...if I get lucky enough to acquire a pair of Urbans, I will experiment on them. I've been looking at the Tobin mod, and that may be the time I try it out along with some B-200Ys. But I think I will leave these E-300/B-302As alone as I am very, very satisfied with them - they have quickly become my favorite set of speakers. I would willingly let go of my Wharfedale W70s and W60s for a pair of Urbans. I'm going to sell my Sansui SP-1500s as they do not even compare to the Bozaks. I had a pair of Klipsch kg4.5s for awhile, sold them earlier this summer, wasn't that impressed with them, don't miss them. Yup...I'm hooked on Bozak. :)
 
Hey Ron,

Funny you mention the Paul Weston LP and your experience. I've found the same thing with the music I listen to on modern speakers. The music is lifeless, missing all the vast and wide open midrange I'm used to. You're right, it's muddy and lifeless.

It sounds as though you and I are walking a very similar path. I sold my early W60's, I wasn't able to find anything that I liked about their sound. The early W70's were worse. Both the mid and woofer run full range, and they share the same cabinet space. The backwaves intermingle and confuse the both of them. All the tweeter has is a single cap. User DC270 ran the drivers through his DATS system for me, bot the T/S parameters. The drivers themselves are excellent! It's the execution that ruined it for me. I also have a pair of Sansui SP-1500's, these I'm going to hang onto for a while. They don't have the dreaded horns. Do yours have new caps? I redid mine and it made a huge difference.

For the music that we're listening to today, you are going to be hard pressed to find a better manufacturer to stand behind. Especially for the money, I don't believe it's possible at this buy-in cost.

I would suggest bypassing the Urbans and go directly to a pair of B-4000 Symphonys. You've already got the E-300's, that's nearly the B302A's right there. The Symphonys will be sportin' 2 B199's and hopefully the venerable and darned near perfect B800A midrange, along with an array of B200Y's. They aren't as deep as the B302A's, foot print is a little easier to deal with. But the best part? It gets the midrange and tweeters up where your ears are! The B302's are low slung and the tweeters come in at your shins. Many people remove the tweeters from in front of the woofers and put them in a separate box that sits on top. With the Symphonys that's all taken care of. Contemplate it on The Tree of Woe.

Don't get me wrong, I do like my W60s and W70s. I like the W70s better due to the added midrange drivers which do make a difference. The two-way W60s are certainly not terrible...but not great either.

As for wanting Urbans...it's aesthetics as much as the Bozak sound. You see, we live in a Mid Century home built in 1960 and we have mostly furnished it in Mid Century Modern furniture and things. This is the main reason I have the W60s and W70s - they go with the time period of our house. I bought the W60s first, a few years ago, not long after we moved in here. Then in May while at the huge Kutztown radio meet, someone made me an offer I couldn't refuse on the W70s as he did not want to take them home, so I grabbed them at what I thought was a great bargain. Now, I'm trying to convince The Boss to let me replace the W70s in the living room with a set of Urbans if I find a pair at a decent price after she shot down the idea of putting the E-300s in there. The Urban cabinets with those legs would look great in the living room.

Oh, yes, my Sansui SP-1500s do have new caps - film to replace the original electrolytics. It certainly helped them. Mine do not have horns either - I didn't know the SP-1500s were offered with horns.

Hey,

Ooops, sorry. I made a reference to the bigger brothers and sisters of the 1500's without actually stating it. My smaller living room doesn't have the room for horns to spread out and do their thing. They compress and go directly through my skull. And completely understood on the aesthetics. It's one of the major reasons I'm dragging home the older stuff. I don't like looking at the modern, skinny towers. Well, I can't imagine the urbans wouldn't pass muster. I think you're good to go.

...I love to see a pic of the final setup I your office.

Glenn, here you go...

You see one E-300 to the left of my desk. To the left of that is a Mid Century record cabinet with a Fisher TA-600 as a static display for now. Sooner or later (hopefully sooner), I'll get it restored and then it might replace the Pioneer SX-1500TD currently on my desk.

The other E-300 is to the right of my desk, not shown in this photo.

Best speakers I've ever owned...:thumbsup::rockon:
 
Glenn, here you go...
Really nice office! Love the whole look of it. I. Bet once the Fisher is restored, that system will sound so sweet!
Cheers, Glenn

Weird, my post didn't show up.
Anyway, your office looks great! Must sound amazing there, and once the Fisher is restored, you'll never want to stop working!
Cheers, Glenn
 
Glenn - Thanks!

The Boss (wife) enthusiastically agreed to my idea of getting a set of Urbans for the living room.

So, Biggles...long story short...I'll soon have a set of Urbans with the Tobin mods already done, so I will discover this audio nirvana for myself by the end of the weekend and will be able to compare them to my stock E-300s.

(side note: I signed up for the Yahoo Bozak group but my application has never been approved? :dunno::()
 
Hey Ron,

Yeah, that's pretty much the rumor I've heard as well. You sign up and wait. I suggest the FaceBook Bozak group, you'll get approved the same day or the next.

Yippeeeeeee on getting a pair of the Urbans with all the work already done. You rock.

Of course, you'll be stopping back by here to give your impression between the two.

I'm feverishly getting a pair of Wharfedale W70's, all Alnico, ready for sale. They may or may not be going up today.

Busy busy!
