dbx 223xs Stereo 2-Way, Mono 3-Way Crossover with XLR Connectors

Do you have speakers that really want to produce 20 to 20K but just struggles like the little engine that just couldn't? Get this active crossover and some subs like me. DBX has been around for years. I purchased some processors from them in the eighties for my first stereo and it appears they are still going strong. Since I've added this crossover, I adjusted the frequency so that my speaker can produce clean highs and mid-bass and passed the lower bass to two subs. It took a while to get the right settings but for my system 70hz appears to be the right high to low cutoff. Yours might be different but just adding subs using LFE to your system is just makes things worst. You can hear what I'm talking about if you go to YouTube and listen to stereo systems that just added subs without using an active crossover. Anyway try this out for yourself and see what a difference it will make in your stereo system.

Simple to use. But does require an understanding of how frequencies work. Easy to set up and use. Effective. Works well for analog minded folks.

solid product, no noise. I found the price a little too high but it does seem quite sturdy.

I've been an audiophile for 30 years. About 15 years ago i integrated a sub, eventually a pair of subs, into my 2 channel system. I did this because a truly full-range high end speaker pair is extremely expensive. Typically starting at $15,000 and up from there. I have a $10,000 pair of speakers that compete with any speaker at any price down to about 32Hz. Below that they roll off quickly. The subs fill in the lower bass. For years I used a crossover to control the cut-off on the signal sent to the subs but allowed the main speakers to run full-range. I thought that anything inserted into the signal before the amp would degrade the sound so never considered a crossover like this. I also thought I had my system dialed in and was happy with the sound. I bought this dbx crossover just to play around with expecting I would either set it aside or return it. Instead, I have been blown away by the improvement in sound. I've detected no degradation of detail in the sound. I love this thing. A few months ago I installed this crossover between my preamp and amp and was amazed

I run 4 active 12 inch main top boxes and 2 active 18 inch sub-woofer boxes. My signal chain is mic/instrument/cd player --> mixer (HPF, gate, compressor, and parametric eq) --> 31 band equalizer (tune the room and ring out the feedback) --> DBX crossover (80-90 crossover point). Although my active 12 inch main top boxes have a built in 200 Hz crossover point or HPF and my 2 active 18 inch sub-woofers have a 130 Hz crossover point or LPF, I prefer to "set my own crossover point" and control the "gain" to the sub-woofer and mains separately with this DBX crossover while setting the signal gain and volume on my boxes at the most optimal point. This DBX crossover allows and affords you flexibility and control over crossover point, gain to the mains, and gain to the sub woofers. That is what you are paying for.

True DBX quality, and very useful in the studio! I have 2 near field full-range monitors and 2 subs (using as a stereo 2-way). This unit allows me to control where the full range and subs crossover, being able to adjust not only the frequency, but the levels as well make this unit versatile and very useful!

Excellent device! ... Improve the quality of my sound system in a surprising way. Exelente aparato! ...Mejoro la calidad en mi sistema de sonido en una manera sorprendentemente.

この商品は電源スイッチが無いため、 スマートプラグを使い電源のオンオフをしてました。 電源オフ時のポップノイズは普通に出るので、 気になる方は遅延回路を組み込むことをおすすめします。 アナログアンプでアンバランス接続可能な点に惹かれ、 「アナログなら壊れにくいだろう」と思って、 長期保証を付けずに購入し使用してたら、 片チャンネルの音量が小さくなってしまいました。 （アナログなのでスピーカーを巻き添えにして壊われなかったのは不幸中の幸いですけど。） 手元に残ったのは音出し確認用に買ったコンポ用スピーカーと買い替えた高いケーブルとアンプ…(泣) 次は長期保証付けて電源付けっぱで使用することにします。 音質は比較対象のものが無いしスピーカー次第でいくらでも変わるのでレビューはできないですが、 ノイズが皆無な点は嬉しいですね。 〜その後〜 （多分出力段だろう）NE5532をOPA1622に交換してみたら、 「元々はモニター的サウンドだったんだな…。」 「音楽を愉しむためのものではなかったんだな…。」 ってことが分かりました。 これ以上改造するなら自作したほうが安上がりなので、弄る予定はないです。 …が、デジキーで送料無料ついで買いしました。 元々付いてる074をド定番の上位互換のTLE2074に乗せ替えたたころ、 一皮むけたように音質改善されました。 今はTLE2074をOPA627と同シリーズのDifetにし、 低音のLF347はADのオーディオ向け高精度JFETアンプに、 高音のLF347は何も足さず引かないTLE2074に、 出力段はTIの高精度、低ノイズが特徴のJFET入力アンプのシリーズのもので、 オーディオ用と化しました。 （すべてユニティゲインで安定動作、電圧スパン(最大)30V以上） LF347は癖はそんなにないが最新のオペアンプと比べると、音が団子気味に感じます。 OPA1604などのSoundPlusシリーズは暖色系で高解像度で音が奥で広がるが、 空間表現が不自然気味。 LMEシリーズは寒色系で、高解像度だが音の広がりが少なく感じる。 （49740は音が曇るような余韻がまとわりつくので全く別物。） TLE2074は完全にプロオーディオ、スタジオ向け。 音が前に押し寄せてくるが団子にならないし、癖が無い。 LTシリーズ（C-Load）は寒色系、高解像度、音が細く艷やかでかなり癖がある。 Difetは単体では最新のオペアンプに負けるが、空間表現が自然で広がりがよく、 低音・高音を補助するように最新のオペアンプを組み合わせると化けます。

I bought this unit with some trepidation because I will be using it on a high end ($50K) stereo. On a live application it would not make a bit of difference as long as the unit does it's job. But, on an extreme audiophile system-- ??? I am crossing over a super tweeter @ 10K, so it is hard to tell the fidelity as most of the program is just air. But, I can tell you the unit is clean and silent and does not introduce any artifacts that distract or fatigue. The unit is 'colourless' and has an invisible sonic signature-- exactly what a X-over should be.

value for money

Muy buenas funciones. Buen desempeño. Lo he usado solo en stereo (separación de altos/medios y graves por canal). Seguro la configuración mono para 3 vías funciona muy bien también (un dbx 223 por canal). Quizá mejor.

A bit pricey, but does what it's suppose to do.
