spica tc 50 이란 요넘이 제손에 들어왔는데
소리가 제법 쓸만합니다
맘에 들어 어울리는 스탠드를 하나 제작하려는데
모양새와 소리를 업그레이드 할만한 스텐드를 제작하려구요
2웨이 6.5 오닥스 우퍼(종이 콘지)와 트위터구성입니다
음압은 84db 4옴 밀폐형인데 소리결은 좀 날아다니는 가벼운 성향의 소리이고
중고음으로 치우친 감이 있습니다(엠프 탓일수도 있지만 같은 엠프를 엠비엘321에 물렸을때는 그런 느낌을 못받았어요)
와트의 퍼피처럼 mdf 통으로 도장처리한 스텐드를 주문 제작해볼까 하는데..
높이 60에 가로 세로 35/38 사이즈입니다
스텐드 덕트를 전면에 하나 내면 좀 저음이 보강 될수 있을까요 아님 밀폐형이 나을까요?
그것도 아니면 로하스 계통의 철 스텐드를 제작해서 올리는게 나을까요?
날리는 소리를 좀 밑으로 내리고 저음을 보강하려면 어떤 스텐드가 좋을까요?

The Spica brochure describes the TC-50 as a deceptively simple two-way loudspeaker based on a 6-1/2 inch acoustically suspended woofer and a 1 inch dome type tweeter. Its crossover network is truly state-of-the-art, in parts quality, circuit layout and, of course, design. The compact speaker is the result of exhaustive research and the latest technology in computer assisted optimization. Designer John Bau had indeed pushed the limits with tools available for the period, creating a time-aligned design with remarkable imaging qualities. Close tolerances were maintained during production and units were serialized to ensure a optimal left/right matching.
Specifications:
Released: 1983, est. 20,000 total sold (post)
approx 7,500 TC-50's / 12,500 TC-50i
Description: Two-way, stand-mounted loudspeaker.
Drive-units: 1" soft-dome tweeter, 6.5" pulp-cone woofer.
Low-frequency alignment: sealed-box Q=0.78.
Crossover frequency: 2kHz.
Crossover: high-pass slope, approximately first-order, 6dB/octave; low-pass slope, fourth-order, 24dB/octave, Bessel; both drivers connected with the same polarity.
Frequency response: 60Hz-17kHz (-3dB).
Sensitivity: 84dB/W/m.
Nominal impedance: 4 ohms (3.6 ohms min. at 4kHz).
Amplifier requirements: 25-100W.
Maximum power handling: 50W continuous, 100W peak.
Dimensions: 15.5" (394mm) H x 13" (330mm) W x 11.6" (295mm) D
Weight: 20 lbs (9.07 kg) each.
Price: $420/pair (1984) / $450/pair (1986-1988); $550/pair in oak or walnut
Schematics:

SC-50i Schematic
Additional Details
Replacement Drivers:
In January 1988 Spica began shipping the revised TC-50 or TC50i (pictured). Easily identified by the shape of the felt surrounding the tweeter, early TC-50 units have a rectangle hole while revised units have a square hole.
TC-50 (early)
Woofer: HIF 17JS 2 CA12, 4 Ohm Audax (FR) / Polydax (US) (specs for 8 ohm)*
Tweeter: HD 100 D25, 4 Ohm Audax (FR) / Polydax (US) (specs for 8 ohm)*
TC-50i (improved, pictured, post 1988)
Woofer: HIF 17JVX 2CA 2, 4 Ohm Audax (FR) / Polydax (US) (specs for 8 ohm)
Tweeter: DTW 100 TF, 4 Ohm Audax (FR) / Polydax (US) (specs for 8 ohm)
* The specs for HD 100 D25 and HIF 17JS 2 CA12 provide the correct response curves etc. however, the 4 ohm version of this driver was used in the TC-50.
