Warwick Hellborg 215?

[Mr. Foxen]

Hence the question. You don't have an answer, you don't know, you just keep trying to change subject.

Hence the question. You don't have an answer, you don't know, you just keep trying to change subject.

I have stated repeatedly that I don't have a clue about Hellborg's engineering experience. Who cares? I was simply commenting on your shortsighted implication that an artist is of no benefit to product development, unless they have engineering experience.

So, now that we have repeatedly established that same thing over and over,.....do you care to comment on my question to you, about your experience as an amplifier engineer? What design concepts have you revolutionized in amplification? I am genuinely interested to see if an engineer has been able to make a significant mark in his industry, while having complete disregard for professional input.

 

[Mr. Foxen]

Why not make you own thread for asking questions to pros, whilst professing repeatedly you don't know what you are trying to argue about? I like how you run with what you decided my profession with in spite of it being stated right under my profile pic.

LOL,...no, there is no reason to start another thread. You belittled Jonas Hellborg's participation in this series of products, and you did it in a way that was quite rude to the Warwick representative (who was nice enough to come here and field questions). You went on to belittle any artist participation in product development. So, I just thought it pertinent to point out that an engineer that disregards professional input will almost never leave a mark of his own. It defies common sense to disregard professional input.

I'm pretty sure my points have been made, ad nauseam. I don't think there is anymore to say on your perspective,...or my perspective of your perspective.

 

[Mr. Foxen]

Yeah, you covered that you don't know the answer to the question. I am still confused as to why you had to repeatedly state so. It does kind of illustrate the point that you assigned to me though, about the opinions of musicians.

Hello.

Anyone who wants to personally experience whether Jonas Hellborg´s ideas regards to amp design are worthy is welcomed to play on my Hellborg rig. You can test it against custom SWR tube pre/LAB Gruppen power; tube Trace Elliot TwinValve; tube THD Bivalve and FET pre Genz Benz Shuttle 3.0. All fine amps with very different technologies, design features and price points. For my needs the last I would let go off would be the Hellborg´s with the THD Bivalve in tow, the best-all-rounder being the Shuttle 3.0. Now the THD is a low watt guitar amp that has a filter that cuts off bass frequencies, so that should be a fair warning regards my understanding of what makes a good bass amp

Anyways...
We can discuss - and should as this is a forum for discussion after all - all that we want regards equipment but we should not base our attitudes on gear, their design or the people behind them based on forum talk. All "truths" are by their very nature subjective, as we experience things subjectively. Therefore experience it yourself. Then you know.

Cheers,

Jonas learned about engineering when he put together his own high end studio in the 80's and found out the cost of hiring someone to repair the gear when it breaks. He has also been unhappy with most of his gear choices since early on in his career and learned about amp and instrument design as a necessity to design gear that he likes.

I still haven’t found a “Direct Radiating Bandpass Cabinet” design - is there such a known design or is this something new?

May be some sort of hybrid?? It seems it should be adding lowend extension, but the overall spl wouldn't be more than the coax can run on it's own. Be curious as to the drivers used. IIRC, you could run into problems with the HF on long excursion as you'd basically be changing it's quasi "horn path" from long to short to long again on every stroke.

Maybe the struck a balance there, or some other internal driver geometry helping remedy it.

Presumably the Coax would be designed so that the "tweeter" isn't interfering with the larger driver (simply moving it forward would do that). I mean, these are pretty high end cabs with supposedly custom drivers (I know everyone has "custom" drivers but it seems likely these are at least "designed in consultation with".
Also, unless there is NO crossover (seems unlikely since they describe it as a "basically a hifi" speaker, the longest excursions would be undertaken by the lowpass driver.

Aside from the arguing, how is the Big Cab as a standalone cabinet?

Think it has been left in the dirt by advances in available cab design by now. It was pretty much the last attempt at doing something new with ceramics before neo took over.

For sure. I just picked up the Hellborg Pre and poweramp and was wondering if I'd like the Big Cab. Thomann is liquidating them so I was thinking of grabbing them. I currently am running a TecAmp M212 but was wondering if a different cab might compliment the sound of the Hellborg pre more.

Hi to Everyone.

The first time I heard a Hellborg Amp was at a Larry Graham concert in London and was shocked by the sound of it......It was a Big Rig anyway, one Big Cab on each side of the Stage as a Side Fill and more amps at the back of the Stage and the Bass sound coming from the Stage was much better than the sound coming from the PA.

It was like that in the Good old Days, big Bass Amps filling the Hall but now Bass Players go to gigs with tinny little DI boxes with a speaker on it.........and then the Bass Sound is at the Mercy of the quality of the PA and its operator........

I was lucky enough to purchase the Hellborg Amp that was owned by Jack Bruce and used on his last record Silver Rails, recorded at Abbey Road Studios.

After that, I started buying every piece of Hellborg Gear that came on eBay ending up with the full Hellborg Line, including the very rare and early discontinued Mono Power Amp 250.

Having the Club Cab and Lo Cab Set from Jack, when I bought the Big Cab I was very disappointed with it because having exactly the same Drivers its performance was very Low on Volume and Bass...............

Something is not Right here and opened to see what's going on in there.....

On opening, I found this Bottom Speaker facing upwards on the same vented chamber as the back of the Top Speaker and decided to change the polarity of it and problem solved (it was in phase with the other speaker but out of phase in the chamber pushing air against the top speaker.....

Then I found out that the Top Speaker is a TF1525CX (OEM for Warwick that is just a TF1525 with a built-in
CDX1-1425 High-Frequency Driver) rated at 250w with 98 dB sensitivity and the Bottom Speaker is a TF 1530 rated at 400w with 99 dB Sensitivity connected in parallel with the other one...

That doesn't make any sense since you are limiting the capacity of the Bottom Speaker to the capacity of the Top One making this Cab very Low on Bass Response.

So I decided to connect them separate to the back panel on individual Speakon connectors to have a compact version of the Lo Cab, Club Cab Setup with individual volume control for each on the Stereo Power 250 Amplifier.

The problem with Artist design products is that they are made for their specific needs and Jonas needs are not mine......I'm a Rock Bass Player and He is a Fusion Player playing with a (Bass?) that only have a bridge pickup... and that's the pickup I never use........

But I'm thankful to Him for convincing Warwick to Make a High-End Bass Amp That I can Modify to my needs...


Very overpriced and arrived too late to a market that moved to Lightweight Amps this product was a failure for Warwick and ended up selling for less than its original price on Thomann in Germany...

If anyone needs some advice on any model of this line of amps, I tried all combinations and modified some of them to suit my needs...

@Musicavenger

I´d appreciate your take regards

1. using the lo cab alone
2. using the hi cab alone
3. differences of lo/club cab´s when used alone

I have the Hellborg mono 250 and Hellborg pre-amp.

These would sit in a home studio with lowish volume.

Thanks,

J.
