Found a MS908 (like boss akyat's) look-alike in RAON and brand is a Crown. Pati yun 10" LF driver sa sides meron din, ang hindi ko lang napansin kung may spikes din like yun sa MS ni chief. ;D Meron kami Crown yun 18" 1000W na double magnet nakakabit sa L36 na bass bin for PA use, oks din ang layo ng nararating. Pero yun nakita ko parang ok na pangbahay.
But the catch is it's only ~5K! ;D Parang ang hirap lang mag audition dun kasi nasa bangketa eh. Hehehe.
Any comments on this brands? Crown, Dai-Ichi etc. Meron ako Dai-Ichi pero DIY yun box, alam ko may magaganda na din sila na buo na.

i'm also interested in feedback on local (or China-made?) speakers. 10 years ago when i was planning to relocate here in Davao, i applied for a distributorship at Daichi. that would include the speaker demo room plus the British brands they import at that time - Mission, Celestion, MF, Tannoy, etc. those were the days when they hired a British guy to design their speakers, pero kahit gumanda ang itsura, if you'll listen to the high frequency drivers, wala pa rin. the bass was also wanting, masyadong matigas, even for powered boxes. this was also true for other local brands, such as Micro, Crown, etc.
lately, however, i think the technology has improved based on what i hear in demo rooms, and on the sidewalks. i never bought any new units though but with such low prices, i'm tempted to buy boxes loaded with 12 to 15 inch woofers and horns (prices here range form P4.5 to P7.5K). i auditioned one here in Davao, pero nakakatakot ang vibration ng box pag tumunog ang organ! i also suspect the horn, which serves midrange to high frequency, is comparatively noisy. i'm still curious though and if i read positive feedback from this thread, i'll probably buy a pair in the next few days. para, masubukan lang.

am actually on the look out for any positive and credible review of locally based or china made speakers, but is to lame to do it myself.... as doing so means buying the unit na, cant get any relaible outcome doing so thru the bangketa.
i do however recall DOHBERTs assistment on the daichi (forgot the model) maganda daw a it was sporting this and that drivers (from known brand speaker manufactures), highs were good, mids, etc. but you have to ask him personally bwt that to be sure. he did some tweaks to it als to improve the what (i forgot).... ;D

I'll be returning there this friday and will investigate more. What caught my eye was it had a nice black finish, a good looking grill too (and hirap mag DIY nito ;D ) and the 10" woofer on it's side. Naalala ko agad yun speakers ni chief akyat eh type ko pa naman yun. It is an MTM design (midrange-tweeter-midrange) plus the woofer on the sides. Also has gold plated BI-Wireable terminals!!! ;D Crown ang brand nito, let's hope na pwede audition ng magandang amp nun shop. ;D

just to share my experience with an early '90s pair of Dai-ichi 3-way floorstanders (CB-100?). bought it at roughly P4K and it's still being sold brand new in Dai-chi shops there in Manila. its response, musically, was really too inferior compared with my other bookshelves including the smaller ones. it's now lying somewhere here but unused for at least 5 years now.
i did some tweaks on it already in mid-90s, which did make improvements but still performed short compared with my other speakers. what i did are as follows (baka may gustong sumubok diyan):
1. disconnect the midrange since my ears heard it makes vocals harsh (ngo-ngo);
2. change the tweeter to US-made (Pyle) and extend its coverage down to mid frequencies (thru the dividing network); and,
3. unwound the wire coil filter on the dividing network assigned to the woofer by about one foot. i also changed the internal wiring and the speaker terminals (to accept bananas.)
the "ngo-ngo" sound disappeared and high frequency was extended; even as low frequency bias for the woofer went up to a level more pleasing to my ears. i think the designer forced the 10-inch woofer to go down to as low as 40hz, which it could not do properly (masakit sa tenga).
ang maganda sa murang audio, hindi nakakahinayang kalikutin. pero sa dinig ko, mas maganda na yung mga bagong labas ngayon. lalo sigurong gaganda kung kakalikutin pa.

One thing i've noticed about the China made speakers, the box are thin. Maybe replacing the box with good MDF one retaining the grill & the face of speaker can do justice with the Sound Quality. The driver are made of aluminum casting which is the quality of a good driver. & a tweak with the x-over will definitely make them sing. IMHO

Amidst the noise of Raon and people shouting, I think these babies can sing. For me it's a good buy, but I won't be buying anytime soon. Another thing I noticed is that the 10" driver is kinda good and reacts/blends well with the MTM drivers. If I were to choose between DIYing another speaker project and buying this Crown floorstander, I would rather buy it. ;D The sound I heard is more than it's asking price. Octaver, I would rather leave it be instead of tweaking the hell out of it. Wires, caps, resistors, etc. that makes up a crossover requires science and understanding rather than just changing it's parts to botique parts. ;D I've heard a speaker that has been upgraded with high priced wires and caps only to find that it sounded the same. ;D ;D ;D now that sucks!  |

inspired by this thread, i searched and found my shelved 10-yr-old Dai-chi CB-100. using Epos 14 as reference with respect to sound, i removed the innards of the CB-100, re-installed an upgrade Pyle for high-frequency, reconnected but filtered the 5-inch Da-ichi mid-range to remove the nasal sound, and changed the woofer for the best-sounding (as per my ears' preference) i could find from a local shop. i had to install and test four woofers before i picked the best i heard, and returned to the store the three others.
was surprised the best woofer i found for CB-100 was also a Dai-chi but with comparatively smaller magnet. bass crawls well and no more heavy bass sound i heard from the originally installed heavy-magnet woofer. with its big box (82cmX35X35), the bass dips lower than what the Epos 14 could achieve driven by Sansui Alpha 907 (160wpc @ 8 ohms / 200wpc @ 4 ohms). i spent a little more than P1K for the modifications.
the modified Da-ichi CB-100 boxes are now used as matched speaker system for a monster Sansui Vintage series amp (AU-X11 - straightwire, no tone or loudness compensation controls - 160wpc @ 8 ohms / 240wpc @4 ohms). the new combination sounds more palatable on the lows compared with using my other floorstander, an ESS Performance 12C. more efficient than Epos 14 too, at over 92dB SPL i would guess.

Didn't Dai-Ichi also made OEM drivers for PYLE and Cerwin Vega? I saw those before in an audio fair. Dai-Ichi is really making better drivers for the local market which is a very good thing for diyers and the likes. And congrats to sandawa on another project, this inspires me to repair an old sony mini compo speakers, but instead of having the drivers repaired, I'll just put in some replacement Dai-Ichi drivers for a bedroom HT. ;D Cheers! |

what i know was that Dai-Ichi's sister firm was the exclusive distributor here for Pyle drivers (mobile audio) as well as Cerwin Vega systems used for commercial applications (disco). another Da-Ichi firm also imported most British brands such as MF, Mission, Celestion, B&W, Tannoy, Wharf, etc. i actually applied with that firm for audio distributorship here in Davao in 1996, unfortunately, i can't afford the minimum amount of bond required.
but i think they did assemble a US brand (was it L.A. Audio?) and supplied MTX with woofers.
