Hey all,

I currently have Focal Polyglass 165V2 splits.

I want to upgrade to a 3 way system and am thinking of the Hertz HSK-163's. Now they seem to be very cheap for what they are and it is a little hard for me to listen to them as the only retailer in Perth that sells them does not have them on display (well last time I checked).

How would they compare to the focal splits? I like the Focals except the harsh tweeter wich is another reason why I want new splits.

I have 2x Polyglass 27V2 subs and at the moment an Audison LRx5.600 that will be sold and replaced with an Audison LRx2.150 and a 1.400.

I know I have to listen to them but am I wasting my time?


Thanks

Emile

Frankly I don't think that's a good idea.

The HSK 163 is a 3 way system based on HSK 165,
but with HV100 added as a mid-range speaker.

I used to have HSK165 for about a year, and at that
time I remember Focal's 165V2's to sound a bit better than this Hertz,
especially in low registers. The highs were comparable and both tweeters
sounded a bit harsh and "too sharp".

In my opinion the only way for this Hertz system to sound better
than your splits is to add the HM1000 mid-range to the HSK165 system.
HM1000 sounds warm and detailed - great for female vocals.
If you would do this, then it's worth changing.

Sweet thanks for that.

I might just purchase the Utopia TN51 tweeters and put another 4" focal driver in..

Yep. That's the way to go!

But remember - you'll end up with Focal's 165W3,
because your woofer will possibly not "catch up"
with the TN51 and 4W2 and you'll want to buy 6W1 instead :hehe:
(then you've got whole 165W3 set).

Nazar the 3way hertz use a much better 6.5inch woofer than the 2way set. Plays lower and puts out more midbass. The HM1000 is also a completely different impedence to the HSK 4inch midrange so the sound will have big peaks and lows. It seems you have no experience with the Hertz drivers so unless you've heard both then you cant really give a objective opinion.

If instalation is not an issue the Hertz 3ways will be far superior to the 2way focals. Only down point is the tweeter on the HSK163's its the same as the focals, however for like $40 more you can get the HT-20 tweeter upgraded to the HT-25 tweeter.

You cant add a 4inch woofer and utopia tweeter to your current focal setup as ull need to get the crossovers as well. Will work out far more expensive than the HSK's.

With the 6.5inch woofers in deadened doors, mid and tweet in the kicks ull have a setup that images very well.

Maz,

If you'll double check it, you will find out that the woofer
in both system is the same HV 165. The difference is in the
crossover and added 4 inch woofer from Hi-Energy line.
I'm sure about it.

The only reason you find this woofer more mid-bass'y
is a lower cut-off frequency in the crossover, which makes this speaker
work far more dedicated to lower tones.

HSK's 163 original 4inch midrange is a HV 100 speaker.
It's impedance is 4Ohm, same as HM1000's.

btw: you can always build a dedicated crossover, even for
system with different impedances - it's not a problem.

you can check both systems at:

Talking about my experience with Hertz speakers,
you must know that I've had the HSK165, later connected to
active crossover, and now I have the HV1600 + HM1000 + HT250
with passive (mid-Tw) and active (Wf/Mid) crossover.

I've also had an experience with Focal's 165K2 set and it sounded
better than HSK-165, but not as good as my current set.

And again I'll say that the 165V2's will sound pretty comparable
with HSK 165. Try it yourself.

Adding the 4W2 midrange speaker to the Focal's 165V2's
will be more expensive, but with no doubt it will sound better
than Hertz HSK-163.

Greets!

Dude the 3ways use the HV165L woofer..

http://www.hertzaudiovideo.com/f_categoria...sp?id=4&idcat=8

click on that, look at the 2way splits and the 3way splits.

The 2ways use HV165 +HT20 woofer
The 3ways use the HV165L woofer

So your wrong there

http://www.hertzaudiovideo.com/parametr.pdf

That shows the Parameters of all the Hertz speakers, check out the HM1000's impedence and the HV100 impedence..

HM1000 = 5.7ohm Re
HV100 = 3.0ohm Re

Your incorrect again

If you know anything about passive crossovers ull find that with the HM1000 it will shift the crosover points downwards. The 3way crossovers are designed to highpass the midrage at 500hz and lowpass the midrange at 4500hz. With the HM1000 the crossover point change to a 250hz highpass and a 2250hz low pass.

So you have a massive gap between the midrange and tweeter u'll have around a 10db drop in your frequeny response!!!

What passive crossover are you using for your current midrange and tweeter? Cause u'll be most likley suffering from the same Dip as well.

No wonder the focals would sound better LOL

.. now I see you're right. I was so sure about it, because in
Poland these sets are sold with the same HV 165 (without L)...
I think that's a local "anomaly" and I surely will ask for that
at my local Hertz dealer. Thanks for upgrading my knowledge

Talking about crossovers its obvious that changing the impedance
will change crossover points. When upgrading I never thought
about leaving old crossover unchanged. You always should
recalculate the crossover elements and change needed capacitors
and inductors. And again - when shifting from HV100 to HM1000
you must rebuild the crossover (sorry for not saying that).

My crossover is build with help of spectrum analyser (CLIO system)
and I saw the diagram - no gaps. I didn't feel to good about building
this crossover myself, so I left this for my car-audio "garage".
(i didn't ask for exact values for capacitors and inductors).

Focals (165K2) sounded better than orginal HSK165 (with original
crossover and speakers). The 165V2 sounded "at the same class".
And again, my current system sounds better than 165K2.

Thanks again for telling me all that things!

Greets!

No probs man, i reccon making custom crossovers are way out of reach of the average car audio user.

Thats why i reccon the the HSK-163's are better than the focals by a fair bit. The L version woofers has massive bass output, check in winISD and ull see what i mean.
