Danny,

i email you via your website requesting info on the transportation cost of 2 or 4 units of M130 to be shipped to Australia, via normal airmail(not express). So far no response.
I would appreciate a response from you, email me at tean _tan@hotmail.com. Thanks.

Sorry for the late response. I was gone on vacation with my family for the last 6 days. I did get your e-mail and responded to it also.

Shipping cost on one pair is $32.95 with insurance.

Shipping cost on two pairs is $54.95 with insurance.

Both of those are via air parcel post through the postal service and will take about 7 business days.

The e-mail that you gave me originally that was tean-tan@hotmail.com did not go through. It kept bouncing back as undeliverable.

[ttan98]

email should be tean_tan@hotmail.com.

Thanks for your response I will contact you again as I am going away for a few days.

Please refer to your email in-tray at GR research website for the speaker order.

Thanks

[Danny Richie]

Got it. When the post office opens up in the morning I will requote the shipping cost and get you a total.

[ttan98]

The credit(payment) details have been emailed. You should get them by now.

With all the commotions don't forget to send my drivers.

Thanks...

[Danny Richie]

They went out yesterday.    Thanks for the order.

Thanks Danny,

Speakers arrived today....I am burning them in at the moment...Well packed, good service.

What x-over frequency should I use between M130 and M165X?
I am using electronic x-over at the moment..

[ttan98]

I miss something, also what is the x-over frequency between M130 and tweeter(seas dome type)?

[Danny Richie]

What x-over frequency should I use between M130 and M165X?

In a three way design I would cross them below 200Hz. Anywhere below that will be fine.

I miss something, also what is the x-over frequency between M130 and tweeter(seas dome type)?

Anywhere in the 2kHz to 3kHz range is good.

Thanks for your response...

Initial testing gave me the impression that the M130 is much better than the M160. The midrange of M130 is very sweet as well very good dynamics. The M160 seems to lack the bass response, this could be due to my design. For the price I paid both drivers are a bargain.

To get the best out of the M160(using a single unit) the ideal size of the enclosure is about 47lit, tune to 40Hz. Is this right? If you have other suggestions please advise.

Also if I double the M160 and double the size of enclosure, according to theory I don't get better bass response. If connect them parrallel I get better effciency and a perception of larger bass, are there any other advantages in term getting better sound reproduction. BTW I am not a bass person, I put more emphasis on the midrange and a smooth top end.

My ideal design is TMWW, where M is M130 and W is M160, and T- seas tweeter. If you think MTMWW is better please explain.

I would appreciate your comments..

The M160 seems to lack the bass response, this could be due to my design.

The M-165X that you purchased will play fairly low in the right enclosure and tuning.

To get the best out of the M160(using a single unit) the ideal size of the enclosure is about 47lit, tune to 40Hz. Is this right? If you have other suggestions please advise.

I show 40 liters to be optimal ported and tuned to the 37 to 40Hz range.

Also if I double the M160 and double the size of enclosure, according to theory I don't get better bass response.

If by better you mean more low end extension then you are correct. The low end extension will remain the same.

If connect them parallel I get better efficiency and a perception of larger bass, are there any other advantages in term getting better sound reproduction.

Yes connecting them in parallel will give you more output and sharing the load on two drivers instead of one will give you lower distortion.

My ideal design is TMWW, where M is M130 and W is M160, and T- seas tweeter. If you think MTMWW is better please explain.

That will be ideal.
