My mate has sold his 2x 1852s, and Pre amp.

There is guy here called luton_soundman, who might have CA18.

I have some freshly reconed 4 ohm 1852s, which would be good, 1x per Channel of Proline 3000.

I have 4x of these.

Speak to Richard at Electrikal Soundsystem, they have lots of PD1852 in their system and may be willing to sell four of them.

You can contact them via their page on Facebook, Instagram or the email address on their website https://electrikal.net/

They're based in both Edinburgh and Bristol.

Hi there,

I have 4 brand new in box 8 ohm pd1852's I'd probably be up for selling if you're interested? I'm changing direction with what I have currently and would like to fund some more drivers. 

I'd probably want £300 a piece and I'm based in Leeds.

Pm or drop me an email northleedscarpentry@gmail.com

Cheers 

Richard

Thank you very much for your suggestions and for the offers some forum members sent me.

I haven't found anybody who sells a Crest CA18 yet. I'll ask in the Wanted section of this forum but if any of you knows anything about who sells one or two I would be happy.

I haven't found any places that sell SAE, Admark, or CVR amplifiers but after reading here how fine the CA18 sounds I guess the Crest will be good for the sound we're seeking. Did I understand that right - we need two CA18s to drive four PD1852?

Best wishes
Axel

CA18 cannot fully drive 8 ohm PD1852s.
Would be great driving 1x 4 ohm 1852 per channel.


It is good for 8 ohm PD1850s/V18-1000.

Hello Levyte,

you have a personal message. I'm interested in your 4 Ohm drivers. Are there recone kits for 4 Ohm PD1852s? I looked everwhere but I didn't find any.

Can a CA18 drive two 8 Ohm PD1852s in bridge mode?

Best wishes
Axel

I would like to ask you for advice. Before I buy the wrong speakers or amplifier I'm trying to find out if two CA18s can power four 8 Ohm PD1852s in bridge mode.  I'm new to this.

I checked for xmax with hornresp. The PD1852 is specified for xmax = 12 mm.


Four PD1852 in Scaled Fane cabs with Eg = 110 V

Displacement is 12 mm at 110 V. The CA18 manual says maximum RMS output voltage is 99 V for each channel. I guess that's 198 V bridged. Does that mean the output voltage of the CA18 is enough for two 8 Ohm PD1852s in bridge mode?

According to the manual the CA18 can deliver 4800 W into 4 Ohms bridged 20Hz - 20kHz at 0.1 % THD. I don't know if they were expecting Reggae sound systems when they wrote that. Will one CA18 be enough for running two PD1852s bridged?

The places where we play have three phase 16 Amp mains.

Best wishes
Axel

CA18s can easily power x2 52s in bridge mode heard it plenty of times in the roots/dub circuit with very heavy bass material.

There will be more than ample power available to run into power compression issues long before headroom issues
