ダンプダクトバックロードホーンの自作

[@文彦斉藤-d4i]

やはりフルレンジ＋サブウーハーよりもバックロードホーンですね。 見事な手際よさですね。 ダンピングファクターの高いディスクリート式アンプで鳴らしたら、最高だと思います。 私は、学生時代にアルバイトして購入したNS-1000Mを46年間愛用しております。

以前、興味本位で長岡先生のブックシェルフ型BH、D-102の開口部を板で塞いでそこに内容積から計算してfd50Hzになるようにパイプをつけてバスレスにしたことがあります。200Hz以下すかすかで50Hz付近だけ少しもりあがったタイトな音のスピーカーになりますた。ユニットがBH用の108Σだったのでバスレフ用の低能率フルレンジなら少しはバランスが取れたかもしれません。ただやはり実用的ではなかった気がします。

[@sergiogomezphotography]

Beautiful work Yamanak! How does it compare to other speakers in that size range? How did you come up with this design? Anyone has built this speaker? Do you have plans?

[@didierleclerc66]

It would be nice if you took a bit of time explaining how you design and compute the transmission line itself.

[@didierleclerc66]

@Tekboy 808 Your answer does not make sense. If the information is available out there it's because TL designers share it. But not this guy. In addition you know that TL design is a lot more complex than regular enclosures. And obviously this guy designs seem to be on the edge of what's doable. So I maintain he should share what his thought and techniques are.

[@goodgoat3096]

The HiVI B4N speaker has a 15 db spike at 3000 hz and would need a serious notch filter to flatten out the response. Above 3000 hz the response rapidly drops off and cone breakup typical of metal cone drivers occurs. The cabinet design may enhance the bass response but this driver is not a good choice for a full range design and no elaborate cabinet design can make up for it.

[@JerryWDaviscom]

Yeah, I noticed the sound did not reflect the effort it took to build the cabinet. There's a big gap in the sound where the music belongs. Too bad. Maybe a good full-range driver would serve better, if there is a full-range driver small enough to fit.

[@jasonmelo1974]

@@JerryWDaviscom geeze, there are so many choices for drivers!

[@goodgoat3096]

@regalblue41 - I don't claim to have the wood working skill that this person obviously has. The fact is that using a HiVi B3S, B3N, or a Tang Band W3-881-SJ or SJF in a simple and smaller sealed (B3) or bass reflex (W3-881) cabinet with a somewhat complicated notch filter would result in a vastly superior sounding speaker than this effort while sacrificing a little bass response. A proper horn design would have an ever increasing throat area ending in a terminus roughly the same area as the driver or larger and not as what this enclosure displays with a "necked down" area at the end. The horn length would also in certain areas be lined with an absorbant material to quench line resonances. This design will become extremely annoying to listen to after a very short period of time. Woodworking skills = A - Speaker design skills = F

[@niyazuddinshaikh482]

[@sebastiancadenas8403]

Una maravilla. Felicitaciones.

[@mcmpgaming1329]

i want one. sounds clear and good range.

[@jdrissel]

So what would we call this enclosure type? A back loaded horn feeding a ported enclosure? This might be amenable to mass production if you extruded the box and the labyrinth as a single piece and then just cut it to width, install the driver and put sides on it. If you used a thermoplastic it could be cut with a hot wire instead of a huge saw...

[@stevezane3962]

[@dwindeyer]

I'm really sceptical of the high frequency performance of these drivers.. The cone area is too large for good dispersion characteristics above 3.5Khz. It should be a specialised wide band driver or coaxial design.

[@BobbyKinstle]

I have a set of those drivers and they really need a tweeter.

[@JayakumaranThangaiah]

@@BobbyKinstle these are HIVI B4N. It's a midbass driver. i have 4 of these crossed at 3.2khz

[@BobbyKinstle]

@@JayakumaranThangaiah I am using a DSP on mine to bi-amp the woofer and tweeter separately and will probably cross around 3khz. That woofer pairs well with the Dayton 1-1/8" silk dome tweeter.

[@raduflorin6154]

Yeah , it's a shame , a pair of full range Fostex FE series , would have been awesome !!

Can u tell me is this a tline. I built one of these for my 15" subwoofer. 42" long x 22deep x 18" high. Fits between tire wells in jeep Cherokee. My port in each section gets wider from 2.5" leaving sub chamber to 4" at mouth of port. Use 45s in all your corners for better flow n curf the mouth less chuffing

[@garywong8361]

This dude is doing carpentry work of art, very neat and tidy, but sounds muddy and boxy, I suggest plywood sounds better and a better pair of full range drivers

[@peschex0d]

the problem is that boxes have their own resonance, there should be some resin or gel coating applied inside the boxes to prevent "sound colouring" from wood box

F特見ると２ｋHｚに変なピークがあってそこからダラ下がりのユニットなので、バックロードにはあんまり向かないんじゃ無いかと。Qtsも0.52と高いですし、2kHzのピークをローパスフィルターでカットして２wayなり3wayの密閉箱か、せめてバスレフで使う特性だと思います。バックロードに使うならQ0（Qts)は10cmユニットならせめて0.4以下じゃ無いと厳しいですよ。

[@momo85895]

全く同感です。 バックロードホーンはQoが0.2～0.3が適してると思います。 自分なんかQoが0.2のスピーカーをかなりダンプしたバスレフで、密閉箱に近い状態で使っています。

コンセプトがわかりません。 1）あなたは木の自然な山塊を使用します。そこでは、その音の振動のモードが音に追加の色をもたらします。音響トランスデューサの概念的に受動的な役割は、振動エネルギーを蓄積することではなく、色を作成せずに振動エネルギーを吸収して消散することです。 2）エミッターのホーン構造は、ホーンの口のガラス面に基づいています。これは、ディフューザーに取り付けられたスピーカーの断面積が増加する気柱の振動に対する抵抗の原因です。 ホーンの各マウスピース領域には臨界周波数があり、それを下回ると効率が段階的に低下します。ホーンの伝送ラインの役割は、気柱を使用してこれらの抵抗をスムーズに調整することです。 私の日本語に怒らないでください、これはGoogle翻訳です ホーンは、スピーカーコーンの背面にロードされた1/4波長の時間遅延を持つ追加の音源です。スピーカーラスターに追加の空気の質量+トランスミッションコラムに空気の質量を追加します。しかし、スピーカーラスター自体には臨界周波数があり、それを下回ると音響放射抵抗が急激に低下します。そして、この周波数は四分の一波長のサイズによって決まります。そして、これもシャウトラスターの領域です。 ラスターの面積を増やすことは理にかなっています。ラスターは、伝送ラインの抵抗のサポートであり、2次音空間の音源でもあります。 次に、周波数グラフにくし型フィルタが表示される危険があります。 しかし、この問題は幾何学的に解決されています。各伝送ラインにはクリティカルゾーンがあり、縦方向の振動を破壊できる抵抗が追加されています。このゾーンでは、2、3、6の振動パターンが抑制されます。くし型フィルターは部分的に整列しています。このフィルターの位置はセットアップ中に調整する必要があるため、スピーカーの設計を解体する必要があります。

My next speaker will be with sonotubes. These are round,reinforced cardboard tubes and immensly strong ( to hold concrete in pillars up to 10 feet). The tubes will be fibreglassed so that they are like drum surrounds for even greater stiffness. Then the only thing is to set an array of bolts to hold them in place and spaced properly. Also cutting a few wooden circles for speaker mounting. I am deciding on tube length but the initial transmision lin will be . 1 5.25 inch driver in a 6 inch tube, then a 8 inch tube, then a 10 or 12 inch depending on the woofers parameters and tuning. After that then I graft 2 tubes on top for a mid and a tweet. Think mickey mouse ears for mids and tweets.
