GR or Adire? - Page 2

Is the speaker close enough to use the same box? (putting the new woofers with more Sd in a A/V1+)

It is close. The ported A/V-1+ box is .78 cubic feet.

The sealed enclosure for the A/V-3 is .55 cubic feet.

The Sd is the same for the woofers in both and they can both use the same front baffles and grills.

How about crossover design? Is the response different enough to need a different crossover?

It has to have a different crossover. Its impedance is different. In the woofer circuit the inductor gets larger and the cap value gets smaller.

I noticed the Q parameters are different and I'm guessing this is why a smaller box would be need for an optimal alignment. Correct?

The higher Q woofers need a larger box, but we have been comparing optimal ported in the A/V-1+ to an optimal sealed in the A/V-3. Optimal sealed enclosures are typically about half the volume of optimal ported, and the ported enclosures allow much lower bass extension.

How long is the wait on a pair of A/V1+'s?

Right now it is within two weeks. I even have one pair here that can be sent out.

What part of the country are you in?

Danny,

The reason I keep on asking about the A/V1+ vs. A/V3 is that I want more bass extension, but I'm worried about my amp with the 4ohm load.

I have a Onkyo TXSR500 for a few months until I can afford a preamp. Do you think this amp can handel A/V1+'s all around?

I live about 30 minutes due west of Chicago.

Thanks,
Brian

Question for you Brian.

Do you or can you build your own enclosures?

The new A/V-3 will give you great low bass extension, will be an easy load on your amp, and takes up no more room than a stand mounted A/V-1+.

It is hard to say how well your Onkyo TXSR500 would handle a 4 ohm load. You would have to check your owners manual.

Most of the receivers out there will handle it fine with moderation. It is when you start cranking that volume knob that it makes it really tough on the receiver.

I am both able and willing

. My plan from the beginning has been to build everything myself. What do you have in mind?

I checked the owner's manual on the TXSR500 and it isn't extremely specific. It says exactly what this link says...Here ...it has ** and I haven't been able to figure out what that means.

Ah, then you can save a considerable amount of money building a kit.

For example: Our A/V-3 kit is what we have that is the closest to what you are asking for.

Our new A/V-3 kit is only $329. The Sonicap upgrade will be $85.

Enclosures will be $400. each. plus shipping.

A fully assembled pair will be $1,400. plus shipping.

You can build them and assemble them yourself for _______?

Seems they left out the asterisk definitions, but the fact that they even list a 4 and 3ohm! dynamic power rating tells me it has an above average power supply for such an inexpensive unit, so should have no problem driving a nominal 4ohm load to fairly loud levels if the A/Vs are reasonably efficient.

Anthony_Gomez · 06-11-2003, 07:33 PM

you should be fine with 4 ohms as long as you are only driving a stereo load. Don't try 4 ohms with 5channels running

just my opinion.

Brian Tatnall · 06-11-2003, 09:06 PM

Greg,

That is what I thought about the 3ohm rating also, but I did notice the 3ohm rating is for the (front) only and so is the 4ohm rating. The all channel rating is 6ohm. Maybe I'll just risk it.

Danny,

I think I'm going to wait for the review from Chris comparing the 281 and A/V1+. I wouldn't mind being able to sample one of your kits either way though. What are the hours you can be called at? I couldn't find the info on your site.

Michael R Price · 06-11-2003, 09:37 PM

I want to hear a comparison too! I keep hearing all these things about the GR speakers, but nothing specifically comparing to something I'm familiar with. I don't think I'll be switching speakers, though... until someone comes up with a speaker as dynamic and full sounding as the 281 for $400.

I used to power my 3 AV1+s with an HK AVR320 and it would just get too hot and made me scared it would fry. For a month that I had this setup I used a fan to keep the heat level down.

I really think these speakers are better paired with a good amp. I upgraded to a Parasound 5 channel amp and it's made a difference in terms of dynamics and clarity.

However since an 8ohm version of the AV1+ is now available why not just get those?

Danny Richie · 06-11-2003, 10:25 PM

Good advice from Tony.

Normal hours are 10:00 am to 6:00 pm Central time.

Ideally I like to get a group of you guys together in one area to send demo speakers out to. Then you guys can compare them to many different speakers, and shipping time and cost between you is kept to a minimal.

True, though I view it as how much time will all channels be driven simultaneously and why even list a 3/4ohm dynamic headroom rating if it didn't have a
