It will not survive the trip around the M15's bent throat very well, however. The M14 MantaRay's asymmetry is a neat idea, and since s fit on them, I see no reason why s wouldn't. MantaRay is old tech, and that one doesn't sound all that good in my experience. Originally Posted by Zilch. Originally Posted by joaquin.

What I do hear is the absence of typical horn colorations. Originally Posted by Salectric. I'm not sure what you mean by "resonance. If so, I can't say I've ever noticed any problem.
It may be the fiberglass horn 32B has less of a problem with this than the metal version 32A. Certainly if you tap the side of the horn, the metal rings more than the plastic. However, I've heard both of them while being mounted in a woofer cabinet, and I haven't noticed any ringing problems with either. As for crossovers, I have tried a number of variations but right now I am happy using the standard Altec crossover designed for my particular drivers.
The Altec speaker used a woofer 8 ohm version with a G in a 32A or B horn. It has a Hz crossover with 12db slopes and a zobel network on the woofer to account for the 's rising response above the crossover frequency. The zobel knocks the efficiency down a bit, so the final efficiency works out to 93 db or so. But the tradeoff is well worth it in my opinion.
The crossover has more extended bass and highs than any of my homemade crossovers, and it is smoother, more detailed and more coherent, despite the fact that my homemade versions use very high quality parts. The crossover is sometimes labelled They come up from time to time on Ebay.
By the way, even though I am using the same drivers and crossover as the , my cabinet is different. The cabinet is an odd looking thing that appears to be intended for ceiling mounting since the horn is mounted underneath the woofer. I built a bass reflex cabinet using the volume and port area of the Altec cabinet.
Its dimensions are more conventional for a floor standing speaker and put the horn at ear height. I actually use it on top of a massive steel stand Sound Anchors that elevates the cabinet by 6". The Sound Anchor stand made a substantial improvement in all aspects of the sound but especially bass extension and control. Page 1 of 2 1 2 Last Jump to page:.
