    Thiel CS3.5 Replacement Drivers and Ohm

    The MDT-32s don't hold up very well over time, in my experience. I got a batch of used ones that tested very poorly on DATS, flat impedance curve with the peak shifted out towards 2000Hz. Apparently, this is a sign of degraded ferrofluid, so that service that would also replace the fluid is...

    Thiel CS3.5 Replacement Drivers and Ohm

    Here are some ideas for tweeter substitution. The D28/2 was used by Thiel late in the CS3.5 without crossover modification, it is the best sub if it can be found, otherwise, the ones listed here as subs for D28/2 itself. These are sonically similar tweeters, they would still need to fit the...

    Thiel CS3.5 Replacement Drivers and Ohm

    Tweeters: Why don't you try repairing the voice coils on the D28AF? Should cost all of $4 for the pair...

    Dennis Murphy Pioneer SP-BS22-LR DIY Modifications

    These remain my favorite bookshelf speakers. I also did the Dennis Murphy mods for the BR-1, the AA+ for about $400 in cost, but I believe these surpass them. They just seem to sound "right" for vocals and acoustic instruments. And for so cheap! I do use a sub to fill in the low end. These...

    Snell problems

    I've done a ton of these woofers, but long ago. If what you need is a fillet filled surround, then contact myaudioaddiction.com for them, 8" I believe, same as for Boston Acoustics. Forget those places charging $40, these surrounds are costing them $1 each, if not less. Crooks, no need to...

    Vintage speaker insulation replacement?

    Fiberglass doesn't fall apart like that when you pull it out. Probably cotton or wool. There are some cotton batts available at big box hardware stores that would be a suitable sub. Keep them off the back of the woofer and make sure you leave an open path from behind the woofer to the port if...

    Sony "Motorboating" Tape Deck- 1982

    Trying to track down my very first tape deck. This was probably my first pirating-oriented piece of hardware (lots of water under that bridge for sure!) must have copied a hundred albums onto tape. Met many a dorm denizen willing to lend me their albums for the sake of screwing over "the man."...

    How To Get Best Deal on Shipping Speakers

    I plan on unloading some speakers, mostly bookshelf and was wondering if there are any programs out there by the shippers (or third parties) to get the best deal on shipping them. I will probably be using eBay and accepting paypal.

    Alright, Who Else Picked Up a Set of Badges for their TC-50s Yesterday?

    I got my pair, but there is a large group out there that appreciate this speaker and would like them properly badged. Hard to believe some go unsold for under $200 nowadays, these set the standard for imaging at one time.

    Rsound Foam Failure after 11 years - Large Advent

    Yes, I experienced early failure on my refoamed 4002 woofers I converted to an econowave some 7 years ago. I think I got mine from looneytunes2001. They were the proper thin wall foam with flat inner ring mounted out front on the pincushion frame. I agree, they should have lasted longer. I...

    Alright, Who Else Picked Up a Set of Badges for their TC-50s Yesterday?

    Vendor apparently has been making badges for a number of vintage equipment. So very cool. https://www.ebay.com/usr/burtnbec

    Alright, Who Else Picked Up a Set of Badges for their TC-50s Yesterday?

    I kid you not that I have had a tickler on eBay for over 10 years waiting to complete my restoration of a pair of TC-50s. Finally, it looks like someone is making replacement badges that seem to have fallen off of every pair made. Six sets sold within 24 hours. Hopefully he will make more...

    Dennis Murphy Pioneer SP-BS22-LR DIY Modifications

    Here is the BOM that is no longer showing. MY PE order was $65 total, but did not include the board, obviously. I see I paid $2 more back in 2015 for the tweeters. I think about $70 in parts for the pair would be a reasonable estimate.

    Dennis Murphy Pioneer SP-BS22-LR DIY Modifications

    These are on sale again for $58 at Frys. I have really enjoyed these over the years with the Dennis Murphy mod, which is essential. An absolute bargain of a speaker for under $150...

    Buying A Multi-Meter

    I have found even cheap meters to be accurate. The red HF model that is frequently given away for free (or $5) is very much right on with readings from my Fluke 77, but it takes a few more seconds for the reading to stabilize. Have had it for at least 5 years. I got it for working on the car...

    Cassettes missing pressure pads

    I found what could be the ideal felt pad replacement. It is 3M SP-820-NA. There are several self adhering felt pads for floor protection use, but this one seems to be the right thickness. I haven't tried it yet, though. Cut with a razor...

    Question about removing vinyl from Klipsch Quartets.

    That is formica and the adhesive probably contact cement. Lacquer thinner seems to be the proper solvent to take that off. A good technique is to soak a thin piece of cloth in it and let it sit on the glue to be removed. After 5 minutes or so, use a plastic spatula to wipe off the goo. Be...

    Minimus 7 Loudspeakers - Measurements

    Minimus 7 Loudspeakers - Measurements

    Attached are frequency response plots generated by REW with a UMIK-1 mic. The speaker is the Minimus 77 w/ the PZ2.1 mod. I must say that I was never impressed with the 7s or 77s, never understood what the fuss was about, though I did approve of the build quality. But these 77s with the...
