C'mon guys,

Pl tell me if it's worthy to go for a dual SUB setup (Alpine type R 12" or type S 12" or Hertz 12") instead of my current single bandpass SUB. Those 2 subs can be powered by my current Alpine MRD-M605 Monoblock amp?

I think he meant the rating so the Sub.. not the amp Zak..

Any ways you got yourself an Alto... you wanna get LAUNCHED through your windshield??.. why else would you want TWO 12"rs ??

Drum roll..... and DOUBLE TWACK-CRACK-BOOM!!!.... "There goes Zak".... ... lol

Once this Alto withstood a crash at 80kms Head on! And the bonet was dented and grills broken etc.. No windscreen cracks, no problems to the door, even the headlamps remained unbroken!!

And you think, this thingy wont be able to handle the bass made from 2 12" type Rs?? Nay man! Those are not heavier than a ZEN colliding head on at 80Kms?? is it??

My poaah accent took a hit for 70 odd ... Including the headlight!... I know the ALTO fisrt hand!!... Which is why I said YOU launched throughthe windshield!...lol ..

2 subs esp. sealed would offer better quality of bass than the bandpass. Your M605 should be able to run a pair Alpine or Hertz subs you mentioned.

and ZAk.. YOu might really want to consider the iDQ's... even from what I read they are leagues over the ALPINE R types... The R types and the X types I have heard (in Zuhiemi's Honda City)... did not like them - but that is again personal choice and acknowledge that too many variables are involved least of which is the installer's idea of ideal sound!

Anyways you gonna be around to witness this first hand right??

Thanks NavinJi. That's so nice to hear! I'm thinking of getting it in sealed Boxes rather than a sparewheel well, Plexiglass or ported install. I think it will sound better and offer nice SQ.

Zuhemi has Type Rs and not type X. And he also has a serious problem with his setup. Maybe too many speakers and too many amps. and everything not tuned well.

And here're the power ratings of typeR subs:
Model: SWR-1222D / SWR-1242D
12" (30cm) Subwoofer (2Ohm+2Ohm / 4Ohm+4Ohm)
Peak Power 1500W
RMS Power 500W
Frequency Response: 24Hz - 500kHz


BTW, my front components will be changed soon. I was thinking about Hertz. 5.25" components will be fine I think (They can be fitted without much modification too). What do you recommend?

I'm planning to move my Bandpass Sub and velocity components into a friend's car who is ready to pay me. So I'm not losing again.

I'm looking for some nice grills for SUBWOOFER. Can't find anything in this side of the world. What about the other side??

The power ratings you mention are Thermal. Try putting 100W at 30Hz into the sub and see! :-)

As fro grills you can use a plexiglass sheet like Viper did. Pester him enough and he'll post pics.

But will Plexiglass make the box sound like a bandpass again?

And regarding Alpine typeR and Hertz, Which sub is the one worth killing for?? (I mean killing some green stuff, not red)

Zak, both are great subs. Different kind of sound though. I am assuming you are looking at the Hertz ES series.

The Rtypes are high excursion designs. Work well in small sealed boxes. Go quite low. But need a powerful amp as sensitivity is on the lower side (85dB). To my ears, they sound a bit "round".

The ES series is a bit cheaper. Again, work well in small sealed boxes. For better low end performance, use in a ported box. These have an overall sharp, punchy sound. And efficiency is on the higher side (97dB), so you will not need much power to get really loud.

Again, this is based on my listening experience with both subs. In the end its a matter of taste really. I suggest you listen to both...

Thanx GunMan!

That's a nice suggestion I think. I'll defenitely give a look to the ES series which is more cheaper and efficient. And what about SQ man? will it suffer? especially when put in ported enclosures.
I like more of sharp and punchy bass rather than smooth bass. But it should go really low too.
(Hope NavinJi is not going to hold your ears for recommending Hertz)!!


BTW, I'm still waiting for your travelling plans!! What's up man??

i think he intends to vent the plexiglass and use it more like a grill than a box.

Yes SZAK... I feel you may like the sound of the ES's too..

Sure will be nice to see Zuhiemi's knowledge getting E-X-P-A-N-D-E-D ..
