More Bass....

WM

The Horns are Vitavox S2 with S5 diaphrams.
The bass units are 15" proffessional drivers, and apparently very efficient, enough so for an 8w amp like mine (but I dont know the make/model).
The bass cabs are karlson stromberg design. Apparently this is a good match for horns like mine.
They whole shebang is in a big veneered box.

Cheers
Chris

 

more squalid member?

that'll be the chicken again..

 

Ju,
I think it your reference to next door's Kitchen, though the Chicken was looking decidedly nervious and twitchy, but he, who am I to comment on members sexual preferences, after all 15" drivers and horn loaded this and that, jeeze it a wonder the dirt old men sqaud haven't raided the place yet

 

Julian, I'd go along with TB suggestion and look at replacing the B&Ws, though not necessarily with Castles. I'd personally look at s/h, Tannoy (Definition or Prestige), JBL or B&W's Matrix range. As you've probably guessed I like big speakers .They might not be as good as the £15k D100 (I suspect Merlin didn't pay anywhere near that figure ), but then you wouldn't be spending more than about £2k.

 

Here's an Ebay pair of Response 3's that might be worth watching, for anyone who's interested.

 

hmmm,
the consensus seems to be crystalising into forget the subs - get some proper speakers. unfortunately this option will probably not occurr this year as christmas approaches and money will have to be spent on other things. shame as there are some matrix 801 s2's for 1300 quid on hififorsale.
cheers

Yes for the perverts amongst you (yes YOU), I was suggesting the listening experience in the kitchen - couldn't think of anything you are allowed to eat other than chicken

Chris, thought of going with Vitavox but domestic considerations precluded that Waiting on a price for some rather tasty compression drivers and horns before progressing - but anything will be built around the JBL 1500AL.

Dev is right as ever - Ju, get some bigger speakers

 

They'll give nice big room filling bass alright, not too sure about the rest of music though

 

Oooh, this sounds like it could just my kind of speaker porn... Sir will obviously be requiring something like this for the weekend.
What horn-loaded compression drivers are you looking at

 

I'm sorry but the CHT-15R will go a good deal deeper (and cleaner) than the Storm. Velodyne are one of the very few sub manufacturers with the balls to quote the anechoic frequency responses of their subs - REL use some variant of the 'in-room' technique which is pretty worthless (tho they're not as bad as some...)

As for the crossover, the REL definitely has the edge but I wouldn't cross off the Velo on that basis without first trying it.

Dunc

P.S. - The REL actually uses a 10" driver. 150 watts into a 10" driver vs. 600 watts into a 15" driver (which remember means more than twice the surface area of a 10") in a larger cab.... you do the math!

 

Saved me a long post Dunc - I was about to say the same (and I'm a bit surprised at Chris' post).

One thing you didn't mention though was that (unless they've recently changed it) REL now use -6dB readings for bass extension as oposed to the more normal (honest) -3dB. This makes a big difference.

Also, I seem to remember that it the recent Paul Miller sub test he found the REL Studio (next one up from the Storm) rolled off steeply below 25Hz.

 

I certainly think Julian should hear them So Class A, when are we all gettting an invite?

Joel, I looked at Goto but the bank manager said no

Beryllium looks a possibility - I do like the idea of some thing like this

 

if there's to be a gathering at class a's to hear the jbl's i'd certainly love to attend.
cheers

I think your bank manager is probably doing you a favour, Merlin. Goto are seriously overpriced and, IMHO, not that great.
I wonder which market those JBLs are aimed at
TAD OTOH...

 

Which one have you got? And, on the accuracy front, isn't the THD of these so low that accuracy is virtually guaranteed? The results here would seem to suggest so: http://www.hometheaterhifi.com/volume_10_4/velodyne-dd-18-subwoofer-12-2003-part-2.html or are you going to start on about transient response etc

By the way, how have you found the EQ and variable servo control?

Matt.

 

Matt, it's the DD12 and if I were constructing a home cinema I would have absolutely no doubt that it is probably the best subwoofer of it's size on the market. The ability to shake the room has to be heard to be believed

Alan Shaw at Harbeth acoustics is a firm believer in cone materials having a sonic signature. I tend to agree (although why he puts those nasty metal dome tweeters in the HL5 I have no idea ).

I am as yet, not convinced of the transparency of the EQ built into the Velodyne. The variable servo control is very useful , although the high servo settings tend to sound very detached and make it difficult to blend with main speakers in a normal two channel setup.

Matt, for movies it's superb. For music it is also very impressive. But it does lack the sublety of something like the JBL's (although of course they cannot go as low or with such impact) Horses for courses I feel and 99.9% of the population would be utterly amazed by the Velodyne.

Joel,

I am thinking of a 3" driver

 

I guess that's really useful if you listen to your hifi in an anechoic chamber then

My Storm is flat to 22 Hz and -3dB at 20 Hz. I know this because I have measured it myself. The nearest room mode is at 25 Hz.

 

He does that because he can get metal-domed tweeters to match to much tighter tolerences than soft-dome tweeters.
Every pair of tweeters is tested at the factory, and pairs are often split because their tolerences are not close enough. He's picky about things like that.

Don't be such a tease, merlin. What are you thinking of?

 

Mmm, if it were a case of gtting the best pair matching only Joel, I would have imagined he'd have used them in the M30 & M40. I had a listen to some HL5's yesterday - I really wanted to love them. Sadly I just don't get on with metal domes The midrange and upper bass were glorious though

Last clue - I have a copy of the crossover schematic for a top JBL on my laptop

 

A 435Be for the May project?
