    Tiny Tiny amp for Lascala

    in Technical/Restorations

    Posted

    I want to try one of these, mainly out of curiosity, on my Lascala's.

    http://www.parts-express.com/pe/showdetl.cfm?Partnumber=230-108

    "Output power: 70 mW (32Ω), 12 mW (300Ω)"

    Can someone do the math and give a reasonable opinion as to the volume I should expect using an Iphone 3 as the source, and this headphone amp as the "Amp"? I am thinking it might be suprising. I have no idea what the output of the Iphone 3 is. I already have a home-made adapter made up to adapt an earphone plug to speaker terminals.

    I can see it now, just a AAA battery making all that music. I want to impress one of my "Car Audio" friends that believes the only way to get performance is with a pair of 1500 watt amps and power wires as big as your thumb. I already have a couple of small t-amps and am quite pleased with their performance. He hasn't seen the t-amps in action yet. I may be in for a disappointment, but I may try one anyway. Thanks, Bill

    If you want to impress them... Get a boombox and drive a pair off the headphone amp... We did that back in the early 1980s and it sounded like a big stereo!

    So your saying the firmware upgrades that are done via the internet that are mandatory for certain features to work that denon adds or fixes will void the warranty? You sure your not talking about hardware upgrade or something? Still doesn't make sense to me. I've upgraded my denon only when denon releases a bug fix or something.

    Yes, that is what I am saying. I would call Denon and see what they tell you. I think they are worried that you will turn it off or something while it is upgrading the firmware and brick it. I have let the Denon upgrade when it wants too.

    Here is an example of what Sony says about their liability on firmware upgrades... "SCE AND ITS AFFILIATED COMPANIES EXCLUDE ALL LIABILITY FOR ANY LOSS OF DATA, LOSS OF PROFIT, OR ANY OTHER LOSS OR DAMAGE SUFFERED BY YOU OR ANY THIRD PARTY, WHETHER DIRECT, INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL HOWEVER ARISING, AS A RESULT OF ACCESSING TO OR USING THE SYSTEM SOFTWARE OR ANY OF THE CONTENTS, PROGRAMS, FEATURES, SERVICES OR INFORMATION ON OR PROVIDED THROUGH THE SYSTEM SOFTWARE. SO LONG AS THIS PROVISION IS ENFORCEABLE IN YOUR JURISDICTION, THE FOREGOING LIMITATIONS, EXCLUSIONS AND DISCLAIMERS SHALL APPLY TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, EVEN IF ANY REMEDY FAILS OF ITS ESSENTIAL PURPOSE."

    The comment I read said that usually there will be Software License Agreement you have to click on before it updates the firmware... It has been a while since I did the firmware on the Denon, so I don't know if Denon is doing it or not. My big concern is what happens when you are out of warranty and it does a firmware upgrade... Who is responsible? I am hoping that Denon would stand behind their product but I don't know if they will.

    I bought one locally a few months ago on Craigslist and have enjoyed it with an HK 3390 powering a few pairs in the basement. Did the fan swap. Fun!

    It's ultra quiet.....no surface noise.

    Years ago I had some QSC amps and I got some acoustic foam (the grey ones they use on studio walls) and put them in front of the fans about a foot away to quiet them down, and it worked fine.

    What? If you upgrade they won't cover under warranty? How do you figure?

    If you take it to a repair shop and they do the upgrade I believe they will honor the warranty but as far as doing it yourself I doubt it. I have heard of some people recently that have done firmware upgrades on other products and it made it a brick and they were SOL. Now I had a PS2 years ago, and I bought the extended warranty and it did the upgrade by itself and made it a brick... It was replaced by warranty. You never know what they are going to say. In another forum people have uploaded the firmware for people to use and they say use at your own risk... If it becomes a brick you are on your own.

    Firmware updates scare me as I am always worried about it making my equipment into a brick. The bad thing is if you do a firmware upgrade and it makes it a brick, they won't cover it under warranty, which in my opinion sucks! I had a few problems with my 4520 when I got it and I did the firmware update and luckily everything went fine and my receiver now works fine. Hopefully I will not need anymore firmware upgrades and the 4520 will last a long time.

    Got my new seats on Saturday!

    I built a quickie stage for the second row to get the feel of what height will be desired (current 11 inches), so don't mind the 2x4 feet; they are temporary.

    If a person was to soundproof a room... And they put some Heresy speakers recessed into the wall (like in the above picture) would they need to treat the cavity the same as the rest of the walls ie double drywall etc?

    Muel,

    I seem to remember a thread somewhere in the BFM forum concerning the driver access. You might want to search over there. Here is a clip from BFM about placement:

    "Decide where you’re going to put your sub. While a middle of the floor placement will work you’ll get better results with it next to a wall, with best results in a corner of the room. It doesn't matter if the cab stands upright or is laid on a side, but either way the horn mouth should be at the floor with the driver access hole, which has no cover, facing either the wall or the floor. In a corner the horn mouth should be facing into the corner from about a foot away. You do not want the cabinet tight into the corner with the horn mouth facing out."

    You should defeinitely pose this question in the BFM forums. Be prepared to be slapped around. The place isn't really very friendly IMO.

    .

    The La Scala bass will be louder too if you turn it around and face it to the wall or a corner but it works fine faced into a room, same with the Tuba, plenty of output unless you are trying out for an SPL contest.

    Even at very loud listening levels with my THT facing my listening position there was no lack of bass.

    I never had an issue personally at Bills forum.

    Good to know. I actually face my THT's out and it's fine. You don't get the added gain of corner loading is all.

    As far as problems at the BFM forums I posted some questions a while back and got snippy responses like didn't you read the instructions and can't you use the search function. Happened a few times. You probably never asked stupid questions there. :unsure:

    I guess some of the people in the forums have never heard "if you have nothing nice to say keep your mouth shut!". I have run into that problem too and it has usually been after I have grown tired of searching for an answer that I decided to post the question.

    Here is the idea. Stretch the THT out, lay one on another, make it a deck for rear seats. The ends would be the ports. The drawing below is of two stretched 48" wide THT's on top of one another. I didn't have time to draw in plywood thickness, but you get the idea. The horn length is to scale as is the mouth and everything else. It's just two 48" wide THT's that are unfolded.

    Why reinvent the wheel? Build a SPUD or 2 and call it a day. It's a proven design made exactly for that particular application.

    Good idea. I don't know if this is the best drawing of the sub. Also, what about the F20 (did I say that right?). How high is it?

    How does that work? Do you wire one woofer out of phase so the sound waves don't collide?
