Old Kustom junkie here. My Kustom Tall Boy (circa 68) 3-15 (Black T&R for Sound Quality) needs a cone job on one of the speakers (stupid me, I used it in my woodworking studio during a lull in playing, of oh... 25 years). Having Simply Speakers in Pinellas Park FL recone it. Question: it's model is a 418-B, was this a common Altec for 1968. Reading lit. they -Kustom- listed Altec Lansing # 421-A (?) as their normal AL. Anyone know the differences. One for Bass-One for Guitars?

The JBL 140's only have a frequency response from 40 to 2500 Hz. The 130's have a response from 50 to 6000 Hz. Considering that the horn crossover in a 2x15 or 3x15 is at 2500 Hz, the 140 is a very poor choice for a 2 way system. The 130 would work great in a 2 way with a little less bottom end. The power handling of the 130 is less also. The voice coil in a 140 is copper. A little heavier with slower movement, hence the lower frequency response. The 130 has an aluminum voice coil so the response is better. I have no history with Altecs. Every driver in my PA except for the horns are JBL E series speakers. I don't think I will ever use anything else. If I wanted to reduce the weight I would use D or K series JBL's.

I am toying with the idea of building a 3way 3x15 cabinet(s) for a more compact PA for small rooms. But I think I would like to split the cabinet into 2 sections with the subs in their own ported enclosure and the mids unported with the horn in the same section. I don't know what this will look like though but I will use JBL E140's for the subs, E130's for the mids and the siren horns as Bud intended.
