Seas Loki MKII Coaxial Speaker Kit - Parts Only - Each

The Seas Loki MKII is a single 7" coaxial driver speaker system from the highly regarded Seas Prestige line. The driver used is the T18RE/XTV2 (H1333).

Consider the Loki MKII Kit in a stereo pair for music listening, or as a hi-end surround sound solution.

This is the most versatile and easy to build speaker kit that we offer. With the tweeter coincidently mounted at the base of the woofer cone, the Loki provides a point source presentation. There is no traditional “sweet spot” for the listener; the soundstage is broad, and the imaging excellent. In addition, the speaker can be laid on its side without any lobing issues. The magnet is also shielded, for worry free installation regardless of location.

The crossover for this system has been redesigned by Bjørn Magne Idland of the Seas R&D team. The new network is less complex than the original, and specifically engineered for this speaker kit. Crossover slope is 12db/octave on both the mid/bass and tweeter. We conducted hours of listening tests between the original and new crossover design. While we are still a fan of the original, the new design proved more balanced in its presentation and worthy of implementaton in the next generation Loki MKII kit.

Coaxial driver Information:

Bass and midrange frequencies are carried by a PP/TPX (clear polypropylene type) cone ideally matched to a special adaptive rubber surround. This results in a very smooth frequency response from the mid woofer.

The coaxially arranged precoated fabric dome tweeter has a low resonance frequency, and integrates with the cone driver to a point source.

The cone of the woofer acts as a horn loading for the tweeter, and the chassis of the dome unit represents the throat of this horn. The tweeter is located where you would expect to see the dust cap on a traditional driver. The woofer cone moves independently around the tweeter.

Assembled Crossover Information:

The Loki MKII kit crossovers are professionally assembled with high quality parts throughout. The tweeter section uses a ClarityCap SA along with Mundorf MOX resistors. The woofer circuit utilizes a Sidewinder 16 AWG air core inductor. Upgrade options include ClarityCap ESA and Mundorf M-Cap Supreme for the tweeter, and Goertz Copper Foil 14AWG inductor for the woofer. Please inquire by email if you require a specific combination of parts that is not shown as an option above.

Cabinet Information:

Recommended bass reflex cabinet is 12 liters (.43 ft3) with dimensions of 8" wide x 15” tall x 11" deep. Front or rear port this enclosure with a 2" internal diameter x 6.5" long port tube. You may also choose to build a 7.5 liter sealed box for the Loki if you would like a smaller footprint and do not require the low end extension that the ported box offers.

Notes:

While creating a wonderful sound stage and imaging in an ideal setup on speaker stands, the LOKI also excels in non-traditional arrangements. We have auditioned the speaker in many unusual locations (on-wall, in ceiling, bookshelf, unevenly spaced, up in the warehouse rafters, etc) with very acceptable performance in every case. This is the most forgiving speaker for difficult locations that we have heard, so don't be afraid to get creative.

We can say without hesitation that the Loki offers audiophile performance in a small and convenient package.

Other options:

Consider using Deflex Panels on the inside walls to stop reflections and help dampen your enclosure. Put one on the back wall and cut two in half for the sides and top closest to the driver. You need 2.5 panels per speaker, or just one behind the driver if you want to keep costs down.
