RCF HDP-45a

Richard Penrose 6:36 AM - 8 October, 2018
I’ve just seen that RCF are bringing out new models in their HD line. The most interesting one for me is the HDP-45a..

Watchm.youtube.com

Some of the more interesting features for me are :-

1/ New amp module derived from TT+ series
2/ RDNet
3/ New cabinet design (HD35 and HD15 also have this)
4/ 1.5” compression driver (745a uses 1.4”)

Other features look similar to the 745 and NX45

133 dB Max SPL
2200 WATT 2-way power
1.5” Titanium Compression Driver, 4.0” v.c.
Neodimium 15” Neodimium Woofer 3.5” v.c.
750 Hz crossover point for perfect vocal reproduction
90°x60°, wide dispersion constant directivity horn
FiRPHASE
Ultra-Light weight
705x442x386 mm - 27.76x17.40x15.20 in (HxWxD)
20 kg / 44.09 lbs

This looks like it could be a step up from the 745a?

So it's like the HD version of the ART 700 tops?

What's the difference between the two anyway other than the grill?
Richard Penrose 12:35 PM - 8 October, 2018
Pretty much all the things I mentioned above :-

1/ New 2200w amp module derived from the TT Series (745a has 1400w)
2/ RDNet features
3/ Slightly larger 1.5” compression driver (745a has 1.4”)
4) Different 750hz crossover point (745a has 650hz).

The amp in the DHP has various DSP settings. Basically an improvement on the 754a and it’s not butt ugly which means a hell of a lot to mobile DJs. Definitely want to hear these and compare them to the NX45a.
Rebelguy 4:07 PM - 8 October, 2018
Glad to see they added PowerCON in and out on them as well.

PowerCON is a must these days! Good call.

is that 2200 RMS or Peak?
577er 2:48 AM - 15 November, 2018
PEEEEEEEEEEEEEEAK That number is already cartoonish enough, you want it to be bigger?

I wonder if these speakers have a high pass filter built in?...or are they like the 745a that do not.
Arjun B 7:03 PM - 31 January, 2019
They have the DSP module on the back, so im pretty sure they do.
Johnnynights 7:28 PM - 31 January, 2019
Awesome if they do..a little later this year I might switch out my srx815ps and get these to go with my bassboss subs.

They appear to have presets and high pass filters.

Nice I'm really looking into them...I need to hear these in person if there out yet.
Arjun B 7:01 PM - 2 February, 2019
They're probably going to sound similar to the 745a, nx45a etc but better since the amp module on the hdp-45a is new. Im pretty sure RCF is just using the same ND940 HF driver in all of these cabs, the only difference being the amp modules and the wood/plastic box

Just seen this speaker added to the RCF website so hopefully release is coming soon!

dj scottie b 11:20 AM - 16 April, 2019
the model on the site is HDM...i guess its the one ?
specs/desc/pics is the same
just askin'
Richard Penrose 11:51 AM - 16 April, 2019
Yes that's the one. The name changed for original announcement.
577er 3:25 PM - 16 April, 2019
If you look closely at the plastic ridge around the outside edge, it slopes in at the top and bottom just enough that the grill can be damaged... annoying, but I can't wait to hear them and compare them to the new HD35A which are the same weight despite the smaller VCs.

i emailed rcf today and was told it they are in production and will be at retailers 4-6 weeks.
thanks Richard for the heads up about the website!
RIDDIMNBLUES 11:34 AM - 31 May, 2019
I wonder how will they compare to the NX45? just sold my jbl srx812's and bought 2 rcf' nx45a, due to be delivered today cant wait, then I see this new hdp45
Johnnynights 3:29 PM - 31 May, 2019

Will do, out here waiting on ups like a crack head lol...still trying to figure out the difference between the nx45 and the hd45 with no luck on the internet, the hd seems to have a larger amp though and is plastic compared to the nx which is wood.

wood vs plastic? wood should sound better imo
RIDDIMNBLUES 1:01 PM - 3 June, 2019
So my NX45's came in this weekend and didn't have much time to air them out, but so far when tested them out I noticed right away a huge improvement in sound quality over my srx12's

These speakers sound amazing and the low end is incredible..everything just punch out more clearer than the srx series..the input sensitivity was low on the srx boxes, wow what a difference on the rcf, even at low volumes this box sounds so much more defined and detailed.

I took a look at the RCF website. The HD45a has advanced DSP where as the NX45 just has boost button. The HD45a also is compatible with their network control so you can essentially tune it from your desktop. The HD45 would be my pick as you can do a lot more with it, but the NX45 is still outstanding on its own.

I already bought the NX45, imo they both will sound very similar, the wood enclosure should sound better, I also like the looks of the NX vs the HD appearance..

The actual model number of the new speaker is HDM 45-A

I follow this discusion with great interest .
I own 2pcs of nx45's and 4pcs TT25a-mk2 and have compared them . They sound spl whise almost identical the TT25a-mk2 is a little bit louder but much more cleaner and defined in sound quality . The nx45 is definetly an improvement over the previously owned ART745's but a step under the TT's.
Why i mention the TT's is because the amp in the HDP-45's is identical with the amp in the TT25-mk2's as i notice , Even the presets are identical in the DSP .
It is wery posible that the HD45's will sound better (more defined, and punchier sound ) than the NX45's just because the amps even if they use plastic housing vs wood . Just my 2 cents ;)
Johnnynights 3:11 AM - 5 June, 2019
Dam if those HDM 45-A are a more of an upgrade to my srx815p I'm going to start saving.

Plus more lighter.

The only reason why I didnt go with rcf in the past was because they didnt have a built in high pass/crossover and I hate carrying external ones.

Looks like these new models have all that plus more awesome.

Good observation, got me thinking now to return the nx45a and swap for the hd45's, not sure if its worth the hassle, will contact my dealer and see my options.

Do you have any pics, video? How is the weight, bass, throw, dispersion, eq settings? Im really curious as Im going to sell my 735s soon.
dj scottie b 1:33 PM - 10 June, 2019
weight is light ( thank goodness)
bass is decent, but like anything else, in the right spaces .
throw is CRAZY.
dispersion didn't pay attention to.
eq settings i didn't have a chance to go thru, i had to go right into battle by myself.
i used w and without subs at different places, worked great .
anymore than that, I'm a neanderthal.
am i happy?
HELL YEA

Yes you do. Do it! Do it!
Rebelguy 9:00 PM - 11 June, 2019
I doubt there will be a huge increase in quality. If the Hd45s used the same components as the TT line then you would probably hear a difference but DSP only goes so far. Realistically your audience will probably not notice a difference.

Pros of the HDM 45 are the 8 DSP presets and being able to control it all from their software. Not that any mobile DJ is using software, but the 8 presets can be useful.

2 CLOSE (C). When the listening distance is less than 4 meter
4 LINEAR (L). When the listening distance is from 4 to 11 meter
2 FAR (F). When the listening distance is more than 11 meter

Side note all the touring boxes are made of wood which will always translate into smoother bass and weight.

I thought the whole wood vs plastic was dispelled long ago.
Rebelguy 12:52 AM - 12 June, 2019
The RCF NX-45A is the wood cabinet version of the ART 745A. The components are supposedly the same. Every review I have read about the NX-45A state it sounds better than the 745A.

Doesn’t this support the whole wood cabinet sounds better than plastic cabinet discussion?

yes I has been dispelled many years ago by respected sound engineers with more degrees than any of us to prove it........In 2019 wood is merely a security blanket or placebo effect.

I am still curious how this relates to my comment above yours. If end users are noticing a difference then how do you explain things?
