It's been a while since we've heard from Harley.
I've heard very little from him since he changed jobs and moved. He's not building cabs and I don't know if he's playing.

Re: Replacement speaker for WCA115PRO cab

is there any particular reason why the Kappa would be more suitable than the other two? Driver displacement. It's what limits how loud a cab can go. The average 410 has 500cc driver displacement. The Delta 15LF and CB158 have 411cc. That makes the 115 the weak link in the chain. This is one reason ...

Re: Replacement speaker for WCA115PRO cab

Either driver would work OK in a ported cab, but neither is capable of keeping up with a 410. That's probably why the Fostex blew. The Fostex wasn't original, and most likely it replaced the original driver that blew for the same reason. A suitable 15 that can keep up with a 410 is the Kappa Pro 15 ...

Re: Downsizing my rig - anyone done it?

I never heard of an amp having the speaker outs wired like that. I wonder if someone has their wires crossed----get it---wires... If the internal speaker is 4 ohms and the minimum amp load capacity is 4 ohms then an extension must be series wired. This is a rare circumstance, most manufacturers won...

Re: Ceramic vs Neodymium

The magnet material has no effect on the sound. There are about a dozen factors which do influence how a driver works, but the magnet material isn't one of them.

Re: Why did the Ampeg cross over the road?

From the reviews (by "name" pros) it would seem that these are the be all and end all cabs. Not by those pros who play mine. :mrgreen: They (fEarful) are considerably better than the vast majority of commercial cabs, but since they're not horn loaded they don't have higher efficiency than store bou...

Re: Why did the Ampeg cross over the road?

One thing I'm intrigued by though is... if 10s, 12s, and 15s aren't optimised for operation as woofers and midranges, why bi-amp at all? You don't, there's no point. If you have speakers with at least an octave differential in their low frequency response then it's worthwhile. For instance, on PA, ...

Re: Why did the Ampeg cross over the road?

Hi BP, I've been reading the forums here and on Talkbass re: using 1x15 and 4x10 and how it's not the ideal configuration i.e having matching cab speaker sizes (solely 10s, 12s, or 15s) is the way to go. Nonetheless this is what I have... 1x Ampeg SVT3pro, 1x SVT410HE, 1x SVT115HE. I am curious as ...

Re: Are low impedance cabinets inferior?

Bob Gallien (in norm stock tons bass book) claims he doesn't like 4ohm cabinets or low impedance cabinets in general.he claims you lose power in the speaker cord and connectors and lose control of the cone? That's simply not true. You will suffer some signal loss if you're using a 4 ohm cab with a ...

Re: 4x10 vs 1x15 vs something else

I've been looking into a pair of Beta12-AII's which are available in NZ for a reasonable price. However, talking about this is throwing the thread off its intended discussion... The OP asked about 4x10 versus 1x15. It's highly appropriate to inform him that there's nothing inherent to either format...

Re: 4x10 vs 1x15 vs something else

Before anyone jumps on a driver size bandwagon you first need to do a reality check: There is no 'signature sound' based on driver size. The sound any driver produces is based on fourteen or so T/S specs, along with a number of construction details, and the cabinet that the driver is loaded into. Th...

It would be useful if your main speaker was insufficient to drive the stage by itself and you always needed the assistance of a sub.

True, but that sub should be part of the PA, not your stage rig. To do so you DI your rig to the PA board.

Dirty pots can cause problems, though usually not so severe. You should rotate them regularly even if you use the same settings to keep them clean.

Re: 4x10 cabs and dip in the mids

From what I can see you're getting the normal sharp rolloff around 2-3k from the LF driver, but this cab also has a horn which isn't taking over where the LF stops, so there's a bit of a gap between the two. Same thing would happen with a 2x12 or 1x15 if designed this way. Most commercial cabs are ...
