just bought a few surplus gears this past week for my hifi collection including this one: denon.jp/museum/products/sc101.htmldubbed "Super Boy" Denon SC-101 was billed to be big-sounding despite its size, probably due to its efficiency - 91dB sound pressure level @ 1 meter @ 1 watt output. it's a small speaker but sounds pretty loud (the loudest in my collection of 7 speaker pairs) with an 8-inch woofer and a soft dome tweeter that extends the highs, it mimics the horns. the speaker units, Denon said, were specially made by Peerless Electronics of Denmark. the only problem is that SC-101 fails on low frequency response. nevertheless, it sounded good when hooked to a powered subwoofer. i'm currently using the pair with a Velodyne previously used for HT and the result is excellent balance on all frequency range. unfortunately i'm not comfortable with a subwoofer, especially powered, between amp and speakers. besides, i'm driving it with a 160-watt Sansui AU-XII vintage amp (no tone controls, using additional gears between it and speakers not recommended.) Super Boy was sold at 54,000 yen per pair when it was introduced in Japan in '79 and appeared in US audio directories in the '80s at $350 per pair, which is slightly more expensive than the original Wharf Diamond speakers. Super Boy seemed to be popular in Japan in the '80s, it spawned enhanced models including a pair for professional use.

felt so bad Tuesday afternoon, i thought i was hood-winked into buying a pair of floorstander Lo-D (hitachi) metal cone speakers (HS50) at P3K. you see, the speakers were stacked up high near the roof of the bodega and an old man at the shop had a difficulty retreiving them. but then, the metal/aluminum speakers were an object of curiosity for anyone into hifi. so, after a unit was tested on a low-powered Yamaha and the shopowner gave the pair to me at a giveaway price, i said "okay i'll get it." (naawa lang ako sa matanda na nagbaba ng speakers).
then, i found out each box weighed less than 10kgs, too light for a 3-way system with a 12-inch woofer. the speakers also don't have terminals at the back, just a small hole where a tiny wire comes out. in other words, the pair was simply a Japanese cheapo. although i immediately paid for it, i picked the pair up only yesterday morning. i thought that was a waste of money and intended to disassemble everything for use on a DIY speaker project later.
but lo and behold, when i hooked the two speakers on my Accuphase amp, they suddenly kicked off. they rocked harder than American Idol's Bogart Bice. the cheap look also disappeared after i cleaned them up. i would be putting a banana-terminal on the two boxes this morning to put legitimacy to these rockers. i might also replace the box with true wood panels to reduce resonance. so far, no trace of ringing aluminums, as how US audiophiles once described Hitachi's experimental metal speakers back in late '70s.

sorry sir, may digicam ako pero ginagamit ko nung bago pa two years ago, ngayon sawa na. i tried depositing my hifi photos on a host site last year pero ayaw lumabas sa kabilang forum kaya tinamad na. anyway, my new metal speakers (HS50) are very similar to Hitachi model HS630 shown at the bottom of the following page: www.niji.or.jp/home/k-nisi/hs-90f.htmone of these days, gagawa ako ng audio collection website ko para madali na thru links.

inspired by proud owners of vintage Sansui hifi gears at Audio Karma, i bought a Sansui SP-K3000 with busted tweeters and midranges at P2K today from a local surplus warehouse. these floorstanders are comparatively heavy at 40 lbs. each. each box measuring 15X14X26.5 inches, 3-way system and with a 12-inch woofer. i know it's easy to restore, just hoping it would sound like my old JBL Century once it's back in shape. Sansui used to be the assembler and exclusive distributor of JBL products in Japan. unfortunately, most of the speakers Sansui sold here in the '80s were their cheapest models and component package types, not the good ones. here are some photos: wasak ang HF and MF units, parang sinadya ng recycling center staff the plastic ID on the speaker grill MF and HF attenuators info about the speaker at the back indicating it's a Japanese domestic model

hindi ko pa alam sir, pero yung mid-range kayang palitan ang assembly cone nyan at madaling ikabit ang wire dahil hindi naman pino ang coil. yung tweeter ang malabo but i could choose clean-sounding units from those locally made, or a Pyle, which is available locally. buong buo pa ang woofer, with cloth surrounds parang upscale AR vintage units.
nahawa na ako sa mga gurang sa AK, ang sarap ng pakiramdam if your involved in restoring vintage gears. wala kasi akong makitang reference nito sa web kaya binili ko, tapos post agad sa AK para may documentation ng rare Sansui vintage speakers.

wanderlust, hindi ako makatiis, binili ko ang isang pares ng Sony electrostatic speakers, may naiwan pang one pair. ang problema, yung nabili ko, busted ang isang ES tweeter. hindi ko naman maibalik. anyway, maganda yung isang working ES tweeter malinis ang tunog. woofer is 5 inches. here are photos of what i bought: front - it measures 13(h)X13(d)X9(w)inches. kung kasama ang tweeter panel sa ibabaw 18 inches ang height good-looking pero fiberglass and wood sidings ang box back - this is where the amp of each speaker is located, 10 kgs. each per speaker but the bulk of load is on the amp. 50wpc, there's a power socket there and one RCA jack speaker ID/label at the back for details the tweeter is flat panel on top of the speaker box. dimension of the electrostatic panel is roughly 2.5X3.5 inches, half cm. lang ang nipis

bought the Sony speakers at P1.5K/pair, parang gusto kong balikan yung isa pang pares, baka buo pareho ang tweeters. kung hindi, DIY repair - exciting. ang nagustuhan ko dito, aside from the electrostatic panels, kabit mo lang ang CDP kakanta na agad.
wala pang napapadpad lately na NS1000 or HPM100 dito. pero mas mabilis sa akin si Diego pag yang models na yan ang nababanggit. considered as high-end items sa Audio Karma yang dalawang yan. BTW, you were looking for a Kenny KA-9100? wala pa rin pero meron dito ngayon sa warehouse, as-is, 7100, less than 50wpc, ang presyo about P1K siguro.

the Sansui SP-K3000 restored, cost minus the tweeters (my old stocks of Velodyne HT surround tweeters) is P240. this is a floorstander that would sell at least P40K brand new based on its performance and size. anybody who's more into sound than looks could easily be convinced to buy this used, once auditioned, at roughly P10K or more. for those who have heard how the JBL Century sounds, this pair is a clone. i was attracted to it since it does not appear like the usual "kabuki" Japanese speakers (with so many tweeters and midrange units and even flashing lights.) the dirty white woofer reminds me of JBL Century when i first saw it in the warehouse. what registered to me immediately was that Sansui was once JBL's exclusive distributor and assembler for the Japanese market (Delta Audio of Delta Motor Corp. was the licensed assembler here in the 70s and 80s.) my 20-year old kid who still believes the EV Interface A was the best speakers he's heard was awed by this Japanese junk. it's still Epos 14 and EV Interface A on top of my list, however.

I've just acquired an american KLH six speaker from a thrift shop and decided to match it with my Japanese Yamaha NS690 surplus speaker from the Pier. The KLH Six I matched the Yamaha NS690 (see pic) with the KLH Six using a Sony CDP 337esD and a Pioneer SX1050. Yamaha NS690 and the KLH 6 This is my personal comparison of the American and Japanese speakers. In terms of weight, the Yamaha outweighed the KLH. It also is a three way speaker with a 12 inch driver while the KLH has 2 drivers with a 10 inch woofer. Its enclosure is thick plywood whereas the KLH is wood vinyl on MDF. There’s about an inch difference in height and depth. The 690 has low, mid, and high speaker connections and two (dial) tone controls in front whereas the KLH has a single (toggle switch) tone control at the back. See back pics of the speakers. KLH 6 back Yamaha NS690 Back I tested using the eagles’ live Hotel California and Nora Jones and some instrumental music. There were two of us auditioning. The KLH did justice to the music, but face to face with the NS690, it seemed to be at par with the 690 only at the tweeter level. There’s a very slightly stronger mid and bass coming from the 690. The American speaker has a mellow sound while the Japanese speaker has a very rich sound. i.e. it seemed to me that the second voice in Norah Jones’ Lonestar seemed to float out better with the Yamaha. It was quite hard to distinguish the two speakers though when doing a blindfold test except that the 690 was always louder. I slowly turned the volume higher for each speaker. When the dial pointed to 34, the KLH bass gave up and gave a loud clipping sound. I shifted to speaker B and the 690 sounded easily on. I assume that this is because the KLH has a much lower wattage than the Yamaha . I used the KLH for three hours continuously and never got tired of listening to it. I will pick the 690 over the six if allowed only one speaker but all in all I am very happy with the KLH Six and intend to keep it. It shouldn’t be played at very high volume though. KLOSS

i noticed that some posters here and on other sites have been eyeing several Diatone (Mitsubishi Audio) speakers. an unsolicited advice: Mitsubishi made a lot of speakers and was the most popular brand in Japan but the best ones are those that are heavy (some heavier than UK-made bookshelf types), with wood/brown (simulated or true wood) boxes, and speaker drivers are solidly built. i was watching a DVD tribute to Cameron MackIntosh (Hey, Mr. Producer) and realized i have yet to post photos of my DS-300V. this model was made for HT applications and is really quite good for mid-frequencies especially vocals. it looks like the small brother of DS-a7, the bottom of a premium line released by Mitsubishi in early '90s. here are comparisons of the DS-300V and DS-a7: DS-300V - www11.plala.or.jp/se_ke5583/DIATONE/diatoneds/index.html the drivers are generally less impressive in build compared with the DS-a7 and the woofer is smaller at 5 inches compared with DS-a7's 6.5 inches. the simulated wood cover is also darker compared with its bigger brother. 300V's original brand new price per pair was about $400 while current used price at Yahoo Japan is about $150. bought it late last year from my friend Toto, a Jap surplus trader, at P3K. DS-a7 - www11.plala.or.jp/se_ke5583/DIATONE/diatoneds/index.html DS-a7 is the reason why i started buying Japanese speakers. it sounds very good and comparable to my Epos 14 and KEF-101 series 2. when i did a research on the web, i found out it was rated at par with or even higher than British-made LS 3/5s, and Italy's Sonus Faber Concertino. it was initially sold at $900 per pair but brand new price went up to $1,200 per pair when Diatone stopped producing in late '90s. its Yahoo Japan used price now ranges from $400 to $700. got it at P3.5K two years ago.
