Please refer to the trial #1 first. LPZYfjNUV-g 0:00 Default (Right) 0:14 JBL D-120 (Center) 0:25 Weber NeoMag (Left) 0:40 Default 0:59 JBL D-120 1:15 Weber NeoMag ■補足 1.アンプはセンターを使い、キャビネットをスイッチング。アンプはNFB無しに設定。 2.ステレオマイクを2M離れた、センター位置に配置。このためコムの存在は否めないのと、実際よりも左右のアンプの音量は小さくかつボヤけています。 3.Weber NeoMagは、1xアルミドーム/1xペーパードームを組み合わせています。このため2xアルミドームより落ち着います。 ■感想 Weber NeoMag; ALTEC 417-8Hに比べると、ミッドハイのキャラクターはJBLに近いです。低音は417-8H以上。また音量は417-8Hに近く能率=100dB程度の印象ですが、JBLほどの音量はありません。 能率の差さえ許容出来れば、JBLリプレースとして有効でしょう。またアルミ/ペーパーは別途比較しましたが、ペーパードームであれば、ALTECのリプレースとしても十分に有効だと思います。低音が豊富で、非常に軽量なのも良いです。 ■NOTE 1.Amp is always center, just switching the cabinet. Without NFB. 2.Stereo mic was set 2M distance from the amps, center (in front of JBL D-120). So there's some com filter, and a bit volume difference. 3.Weber NeoMag I installed was 1xAL dome+ 1xPaper dome combination. So the high-mid is not showy than 2xAL dome. ■My impression Weber NeoMag; High-mid is closer to JBL, than ALTEC. Lower responce is stronger than ALTEC. Volume is close to ALTEC, so maybe this is efficiency=100dB or around. Not louder than JBL. I think it's good for JBL replacement, if you can cover the efficiency difference (It's perfect if the efficiency is same...) I can say Paper dome is good enough for ALTEC replacement. NeoMag has strong low, and light weight.

0:00 NFB=on 0:16 NFB=off 0:32 on 0:48 off 1:06 on 1:23 off AMP=center. NFB on/off SW loaded. SPK=JBL D-120 リプレースメントSPKに関するオマケです。 FenderのSPK交換する機会があれば、NFBカットを試されるよう推奨します。サウンドはopened, sparkle, direct, dynamic...後悔はしないでしょう。 This is an appendix of some replacement SPK trials. I highly recommend to try none NFB, when you have a chance to replace Fender SPKs. It will sound more opened, sparkle, direct, dynamic...I bet you won't regret.

0:00 Default (Right) 0:13 JBL D-120 (Center) 0:25 ALTEC 417-8H (Left) 0:40 Default 0:57 JBL D-120 1:12 ALTEC 417-8H ■補足 1.アンプはセンターを使い、キャビネットをスイッチング。アンプはNFB無しに設定。 2.ステレオマイクを2M離れた、センター位置に配置。このためコムの存在は否めないのと、実際よりも左右のアンプの音量は小さくかつボヤけています。 ■感想 1.Default; あまり癖が無く、TwinRverb向きだと思います。音量は小さいですが、能率=98dB程度の印象です。 2.JBL D-120; Loud&Clear。ハイミッドをてなづけるのは少し難しいです。歪み系にはあまり合わないと思いますが、EVHはGreenbackと組み合わせていたそうで。遠くで聴くぶんには良いのかも知れません。能率=102dBというのは理解出来ます。 3.ALTEC 417-8H; D-120よりもミッドハイが若干削れています。パツパツ来ないので、多少てなづけやすいです。歪み系もD-120より多少は許容しやすそうなので、MESAの初期に搭載されていたのは理解出来ます。音量は能率=100dB程度と納得出来ます。 ■NOTE 1.Amp is always center, just switching the cabinet. Without NFB. 2.Stereo mic was set 2M distance from the amps, center (in front of JBL D-120). So there's some com filter, and a bit volume difference. ■My impression 1.Default; There's no special peak, maybe good for TRev. Lowest volume, maybe efficiency=98dB or so. 2.JBL D-120; Loud&clear, but it's a bit difficult to tame the high-mid freq. Not so good with high-gain amps. I can feel its efficiency=102dB. 3.ALTEC 417-8H; Scooped high-midrange. High-mid is not so aggressive, and a bit easier to tame than JBL. Maybe distortion sounds better than D-120, so I can understand MESA preferd this in the earlier days. Volume is just in the middle of the 2 above, so I can understand efficiency=100dB.

On March 6th, 2010 the Banks crew tested out the rail's new "Stroker" 427 cu. in., twin-turbo 7.0L Duramax engine at the NHRDA Nationals in Wittmann, Arizona. The numbers for this trip out were 7.670 @173.54. We were a little faster back in April 2009 when we ran 7.17 @ 181.08. We've also run a best trap speed of 190MPH with the car on a separate test session. All those runs were with our twin-turbo'd Duramax, and now we're getting set to hit the track with a supercharged configuration. Stay tuned for that!
