  1. Does anyone have a schematic for the 930II x-over?
  2. I’m taking this in a slightly different direction. I’ll keep all three drivers in the cabinet. I’ll cut it down to 23” and make up the lost internal volume by adding what was cut off the bottom to the back. It’ll be a short & deep T930II that’ll fit under my TV.
  3. I’m considering shifting gears on the project, as a 930II pair has popped up locally w/ rough cabinets & rotted woofer surrounds. All that the new center needs is the midrange and tweeter. The mids & tweeters are identical between 1030 & 930II. The x-over points are close enough (just a different point at mids & woofers). After reading recent posts regarding x-overs for either speaker, my question is this: is it possible to modify the 930II x-over to eliminate the woofers and still present the amp w/ an impedance somewhere close to the 1030 (around 4 ohms)? I have very little experience w/ x-over repairs/mods/builds and would appreciate any advice.
  4. I’m searching for a T-1030 set in rough shape. Maybe bad woofers and/or cabinets. I really only need one for its mid, tweeter and x-over. I’m open to purchasing either a single or a pair. I’m going to build a C-1030, similar to my C-830.

  5. Bill @ http://www.millersound.net/ repaired the voice coils in a set of 4 1030 woofers for me years ago. I listen to them every day & they are perfect His cost was very reasonable (less than buying replacements, if I remember correctly). In the “family” photo, he did my 1030, A70, A60, & HD5 sets. You can call or email for a quote. Tell him Dan in Chester Springs recommended you. Best of luck!
  6. joerand, I was just revisiting this string and noticed your post. I have owned 830 (Series II) 930 (original) and 1030 sets. I found a significant difference in bass response between 830 & 930. Difference in bass response between 930 and 1030 less noticeable. All are wonderful speakers. My listening spaces for these speakers are very large and L-shaped (LR open DR upstairs, Home Theater open to Billiard Rm downstairs). I have to agree w/ Gerry. My favorite of all combinations over the years, is 830 Series II paired w/ a competent sub (M&K are my favorites). Honestly, if I ever find a nice local 830 II set, I'd probably swap them in for my upstairs 1030 set. I'll stick w/ 1030 set for home theater.
  7. I highly recommend reaching out to Bill @ http://www.millersound.net/ to see if he can rebuild it for you. He has been able to replace spiders on the 4 BA made woofers out of a 1030 set, rebuilt voice coils and custom-cut aluminum dust caps for a friend's Totem (proprietary Peerless) woofers, and done countless re-foams for me. The guy is a master craftsman. If you can't get OEM replacements from Boston, give Bill a shot. Tell him Dan & Ashlin in Chester Springs sent you.
  8. I fell in love w/ the A60 Series II in high school (mid-80's). Although I've owned T-830, T-930, T-1030 (currently two pairs), I still love my A-60 set. They are now paired w/ an M&K 12" sub and are glorious. They provide wonderful imaging and are pleasant to listen to up through moderately loud volume levels. A pair can be easily found for $25-$50, they have a relatively small footprint, and parts are easy to find. You can't go wrong!
  9. Great info! Thanks for such a thorough explaination of the difference in designs. I see that the 930 has terminals on the bottom, & 930 II has them on the back. So I imagine you are correct that the older 830 has them on bottom and newer on the back. A neighbor loved the 830 set that I sold a few years ago to a friend. I'm helping him shop for a pair. I have two systems w/ 1030's now, and do miss the 830 set sometimes. Maybe I'll get another set some day when my wife is out of town:)
  10. Gerry, I see T830 pairs with binding post on the bottom, and others w/ binding posts in the back panel. I'm wondering if this is an easy way to distinguish between your generation x-overs and the older version. If so, which is yours? Thanks.
  11. Gerry, Very interesting to read about the change in x-over design on the T830. Please see attached link: http://www.diyaudio.com/forums/multi-way/210503-building-c830-center-channel-match-boston-acoustics-t830-t930-t1030.html I noticed a big difference in the sound of the 'donor' pair vs. the pair that I've had since the early 90's. Is there a change in serial number or a date code that someone can look at to determine which version a pair fall under? Was there any change in drivers? Or could someone simply swap out the crossovers to achieve the improvements? Thanks. Dan
