DLK Speakers = House Product Line for Schaak
Think I may be of help here. I'll keep it short. The DLK speaker line was the house speaker of a midwest electronics store chain known as Schaak Electronics, no longer in business. Based in the Minneapolis/St. Paul area, they had a number of stores. 25-40-maybe more, don't recall. As I was saying, the DLK Line was the house speaker and while I worked for the company during college in the mid-late 70's, this line was the speaker to have-in the area. The store was a mid range stereo store with the highest audio line handled being the Harmon Kardon product line-while I was there. Back to the speakers, the retail price for the speaker set was $1,200.00. As for the sound quality, that is purely a matter of taste. While I have not been in the industry for 25+ years, I would qualify the speaker as being ok to better in sound quality when driven with a clean power source. At 20 years old-when I bought them, they were a great party speaker and used them as such many-many times. Now, I find then a little flat on the high end and have augmented the sound with a second set of higher end bookshelf speakers which are more solid in the higher end. The nice feature of this speaker is they do not need a power monster to drive them. I have a HK670-bought with the speakers-65 watts per channel. I do know, for a fact, when powered to about 7-8 on the volume dial, no remote here gang, they will rattle the china in the house next door, with the windows closed in both houses, and keep several sororities awake long into the early morning. No longer have the exact specs, 8 ohm, non-descript 4" non-dome tweeter, 5" midrange and 2 active 12" woofers. The system also comes with two, looks like, home grown cross-overs with 2 pods mounted on the front under the foam speaker cover. Max power is about 150 watts a side. Hope this helps. Chuck
